  1. Here is a puzzle for you. It has certainly been puzzling me and I have yet to determine the answer!

    I have been looking at the gear selector mechanism. At the front end are three forks with detents for each gear and neautral. As the lorry is chain drive with the gearbox at the back, the selector rods are three feet long. When we salvaged these parts, we were in a hurry to get away so we simply cut the rods, or tubes as they turned out to be with the view to repair them later on.

    401.JPG.766aad40b24fca744bc3b58f96549981.JPG

    That moment is getting closer but I cannot see how they were attached originally. There is no sign of braze or weld although the corrosion could hide a welded joint.

    402.JPG.648ad8a9f46da3b34a3a6b133ceb6e50.JPG

    Interestingly, each selector has a hole in the side and, when shaken, rattles so there is something loose inside.

    403.JPG.600edb73c0b733ae7284ec79bec4cbc0.JPG

    404.JPG.be40d4c44efd75b6df5be57a08f0fae7.JPG

    There is a discontinuity about an inch away from the selector and when I put a screwdirver down the tube, it bottoms out here.

    405.JPG.dcb207394f0a3e1ad18b38faaf7ebd4f.JPG

    I can't see how the joint is made but, fortunately, we have another set of selectors although they are a bit rough. They have corroded through on the joints but this hasn't made it any easier to understand!

    406.JPG.3d9e2978c3d81f7c2ceaec4f8afff6c7.JPG

    407.JPG.d6a5adc47eb9bd2e5974a51ba94a2a7c.JPG

    In the bottom and the top rods you can just make out a lead button which is free and rattles. In the centre one, you can again see signs of a joint about an inch up.

    409.JPG.15d6168d53bcb847b5613fc4e56002e3.JPG

    Looking at the centre one, it shows signs of a drilled hole but really quite a large one. Certainly larger than the bore of the tube.

    410.JPG.c2c2e1f9cc82a9c1e098299ff4bbc9ad.JPG

    Now, I can make a repair by drilling the centre and brazing a peg into both the selector and the tube so I have a solution. However it really irks me that I don't understand what they did and why! Any thoughts would be gratefully received!

  2. I have been pushing on with bits for the fuel tank and seat box installation. First job was to take a look at the petrol tap.

    401.JPG.cb6fe60dfeb5357d2f82ade0ed18a110.JPG

    I filed the ends off of the split pin and removed the washer and spring. It was pretty mucky!

    402.JPG.65840d5adce4a3ec738e97b495977d19.JPG

    More gunge!

    403.JPG.6ea9dc1f797a409a55d921ec13b6934a.JPG

    A tap with the mallet and it came apart quite easily.

    404.JPG.7c0e26527d9b00e660bedad395df8abb.JPG

    A gentle wire brushing all over along with a bit of emery and it all looks OK.

    405.JPG.5e7ff0fd256500a10a280fff9b4812fb.JPG

    I lapped the plug in with a bit of metal polish and then treated it witha smear of graphited grease before reassembling it. It works very smoothly and has a most satisfying feel.

    406.JPG.3131c88029f2082ffa8793d94a03377b.JPG

    The banjo was missing so a turning and silver soldering exercise soon remedied that.

    407.JPG.3d9c6b0c15b607fc8af890ce593295c4.JPG

    Then onto the quadrant casting. I clamped it down and skimmed off the runner and riser before marking it out and drilling it for rivets.

    408.JPG.d904fa5b34acada4af472ace2708e96f.JPG

    409.JPG.ab22f65b9de145710edfe198a6c78e9c.JPG

    Of course, the tap needs a handle so another fabrication was in order.

    410.JPG.12bbc802d71a69b7105b14a80fea03a9.JPG

    411.JPG.bf64fc82ecfa79916d8ab47e024c367f.JPG

    A polish up and rounding of the edges and it is ready to fit.

    412.JPG.934db4fa21404572df9dcc87b4205454.JPG

    All of the tap parts lined up. The bit of bar is a random length from the drawer as I will have to set that on assembly.

    413.JPG.9de3678092403fb55af5e4c812ca5c57.JPG

    Dad has been painting the components of the seat box so we can have a nice assembly job the next time we are together. Gear and brake levers next!

  3. Progress continues. Dad has primed the seat box panels.

    325.JPG.0e5dbdf742de9ccb02d30db78b3f1857.JPG

    We have drilled and bolted them together.

    326.JPG.539882644e431f60d40f933d08c188bb.JPG

    327.JPG.70f7f2fd766912bc7ce84a9aceeba80b.JPG

    I have since rivetted on the angles and Dad is continuing the painting.

    Whilst doing this, we noticed that there are two angle brackets rivetted to the ends of the box so I ground off the heads, punched them out and levered them off. Dad has cleaned and painted them so they will be ready for drilling and fitting next time.

    328.JPG.605114a3072543186a5c64dcee4c828d.JPG

    329.JPG.31d802aa0e41d9c1d25b4ed0e82bf515.JPG

    Well, we have been working hard on the new box and brackets but what about a fuel tank? When I completed the Dennis tank, I was feeling really proud of myself so I went to show my pal Barry. His response:

    'Why didn't you ask? I have a spare one over there!' I took a look and rather than a Dennis, I saw an original Peerless tank in first rate order! Barry felt that I could give it a good home and so it has been awaiting the moment.

    330.JPG.c7a0a77474bbcdf7949fc04a65bd5eae.JPG

    It really is a lovely tank with the original makers plate on it still.

    331.JPG.825a5b31e75f971d00df5156f81d549f.JPG

    And the tap!

    332.JPG.ba8c7d1746dd8a400884d5f5f8f9447b.JPG

    We took the tap off so that is awaiting cleaning up.

    338.JPG.556a3f312d2d40039a905fbdcfa7965d.JPG

    Dad has set to and started cleaning up the tank for painting.

    339.JPG.c4d916ef05410bc41c31dae287bd1b6b.JPG

    I understand that it is now green so what a lovely thing to have. Thank you Barry!

    340.thumb.JPG.c395fcfcd1e0d8b42bd13698b7cf49bb.JPG

    On the end of the seat box is the petrol tap lever, conveniently positioned.

    341.JPG.172d3302cff3c7d5f0d7d8014faa90b4.JPG

    Unfortunately, it is broken and incomplete but one of our forum friends very kindly made a 3d print of it for me to use as a pattern.

    343.JPG.8f22210806f0e6f539548ea1333fe28f.JPG

    Another pal, braver than I , does aluminium casting in his back garden and he very kindly offered to pour it for us.

    344.JPG.5db7eae0538e77127b81bd55dfb1ce8f.JPG

    He did say that getting it out of the sand was a bit tricky!

    345.JPG.51312aac08c65beb423e807ce6821be4.JPG

    346.JPG.1a883474abd299249f1fd523c44c4002.JPG

    They just need a cleaning up and drilling and they can go on too. We are making progress!

    347.JPG.12b8e7b070147952be8c824c8260d00a.JPG

    We feel that things are really beginning to move now but we couldn't do this without our friends. Many thanks Chaps!

  4. Hi Barry.

    No, I have had it for a few years. It was an opportunistic purchase from another old lorry man and sits next to the Bridgeport in Leicester. My original 10 tonne press now lives on the floor in Devon. I find it a lot easier to work standing up than kneeling on the floor these days! It has proved to be a very good tool and much better than hitting things!

    Steve

  5. As usual, we are doing several things side by side and one of them is the seat box. This is of steel construction with the fuel tank hung inside on straps. Our predecessor with the lorry had replaced the front panel but, as you can see, he made it a bit short so it was packed at one end with a strip of wood.

    301.JPG.682fd8753a28a0d02f184e7290176a62.JPG

    On the left, you can see an original tank bracket which has had the rivet replaced with a long bolt. The bracket is a piece of bent steel. However, on the right you can see the replacement which is a piece of black angle welded in.

    302.JPG.086399a07225aa9b37ce79c472dd9810.JPG

    303.JPG.f252ffc5afd1d4d9c2d186f7465fd740.JPG

    304.JPG.62de9efaf188c1cbc7ba009d53a05672.JPG

    This is the original front plate which has had it but which makes a good pattern. In the left hand end, you can see the tensioner casting which is riveted to the strap. This one has proven salvageable.

    305.JPG.55327d085981813cd0f8f4a177e927f4.JPG

    Dad started on the new box by getting the steel bent. He then drilled and profiled all of the bits.

    306.JPG.478a6d859002a20bbea0a85ae0db80fd.JPG

    It was a tedious job and he was glad to see the back of it!

    307.JPG.28b263ce068e57709f195e455d9c189f.JPG

    He turned up the new pins.

    308.JPG.d8599ec9cafb39a0fa33188728780e26.JPG

    An original strap had survived in the heap to make a pattern.

    309.JPG.d5f09dff5a03a8803382384394158ff2.JPG

    Unfortunately, the tensioner casting had been dismantled with a cutting disc which had damaged it beyond repair.

    310.JPG.562006c5deb29b0cd2da141b8e4a731c.JPG

    I started off by fabricating  a replacement. I welded this one. You can tell that I did it by the amount of filler used to get a decent shape!

    312.JPG.bdacfd14fa1eafe2a52920010c073031.JPG

    Dad fabricated the tensioning bolts. Fortunately, only two of these are needed.

    314.JPG.3193d45720a80b0816fd4acd568368e1.JPG

    Then we had to bend the eyes in the ends of the straps. I keep a big lump of steel especially for making up jigs like this.

    315.JPG.27fdff7a3da78941784b437f08884562.JPG

    The G-clamp was used to provide an end stop for the strip which we pulled around hot.

    316.JPG.d4a29642c05ca6893039245eefa23c87.JPG

    317.JPG.a23d5183261c984ecdf90062ff824686.JPG

    I was very pleased at how consistent we managed to make them. They need to be the same length otherwise the tank would sit with one end down.

    318.JPG.fa044fefde770e7c360b3a8ea1fdad52.JPG

    Dad drilled and riveted them up.

    319.JPG.015bf91d58e209b30cbfea11b0dd0399.JPG

    320.JPG.cceaca1fbf2de01d4a7777ba5a6b6af8.JPG

    321.JPG.09302c5894e2efdf590a9a69f7a0cb53.JPG

    Two have eyes in only one end so that the clamping casting can be fitted. We left them off at this stage so that we could get the length right.

    322.JPG.fddad8f9146fe4dd3dbb1353ad0518d7.JPG

    Then I had to bend them to 7 1/2" radius for which I used the press. This was a bit painstaking and took a while to get them consistent but they were OK in the end.

    323.JPG.a3807283f4b6d83cdf233c8218d1b3fb.JPG

    324.JPG.92e72957fc98d1607ec434e222f989aa.JPG

    Seat box itself next.

  6. Did a little more this weekend. The correct 3/8" key steel has finally turned up so I set to and made a pair of keys for the other sprocket.

    181.JPG.5ba786780efa11c866e44599796b337f.JPG

    They stood a bit proud but a file soon sorted that.

    182.thumb.JPG.c955879e85fedd46bb82656eddb0e5c1.JPG

    Then of course another tag washer! I hadn't spotted that we would need one so out with the hacksaw and files again. Fortunately only one required.

    183.JPG.8fed0d08614f9ed23dec918ad55d4916.JPG

    185.JPG.6665806bda4e38f7298d36df1f4d8498.JPG

    Then the fun bit of trying to tighten the nut. I stuck in the vice as hard as I could and then Dad hung onto one end with a 3/4" drive socket, tommy bar and a piece of scaffolding tube whilst I leaned on the other with our second biggest spanner. Hopefully, it is tight enough but time will tell.

    186.JPG.660ab56fe74ebf6fc86f2885bed2e78a.JPG

    187.JPG.2a71430226ea2e42446e09ab75d2aa0c.JPG

    Then insert into carrier checking that the gland nuts are in place and slide over the bearing. Secure with screws previously made by Dad.

    188.JPG.546db62802851c241a2c423deeea01e1.JPG

    Dad is painting it at the moment after which I will wire the screws.

    On to the next job!

    Steve  🙂

  7. Next step was to fit the half-shafts. Firstly, we needed to secure the chain tensioner into place. This is done with a coallar screwed into position using holes in the face to get a purchase. The outside of the collar forms a running surface for the oil seal.

    102.JPG.c37febc6db5dd6b215f1576ee9483a3f.JPG

    103.JPG.daa0f543e45f55032ab363c2bd57daee.JPG

    We have three retaining collars to choose from. These go behind the bearing and keep the half-shaft in place. They also have a groove for the oil-seal felt.

    104.JPG.081ae2e08d519b6aa75c43b0fdf28bb8.JPG

    105.JPG.ef0965021b42ba3107413ab1cc65aea6.JPG

    I cut strips of felt and pushed them into place.

    106.JPG.7df62732ebb5c0c43b54bd9b47438068.JPG

    Once fitted over the collar, the bearing could be mounted. These are double-row self-aligning bearings and, whilst a little tired, will fight another day.

    107.thumb.JPG.5baea4eca712167dce5de4260be7157e.JPG

    109.thumb.JPG.3f2c1cf8e1777b8261e890297cc4ce7c.JPG

    They are retained by a nut and locking washer.

    110.JPG.74b8b080159611142c942658d1ac4522.JPG

    I had previously spent a couple of evenings filing them out and they were probably only a penny stampings originally! The bent-over tag locates in the keyway in the casting.

    111.JPG.372f5c92f2c087c61bee2fc68e286fb2.JPG

    112.JPG.9ee657dc5175369f65ddf112234d62f3.JPG

    The nut is just a simple pressing as well. Fortunately for us, the FWD hub-nut spanner fitted it.

    113.thumb.JPG.e2c1f88589748c69d1f7ce3f53c4a3c6.JPG

    Bend the tag over and that job is done.

    114.thumb.JPG.377ed77cd7581241e63e1e38aef9509d.JPG

    115.JPG.135c9b06a11a5d81ba3fa32af37ba7bb.JPG

    Slide the shaft into place, locate in the differential and over the bearing.

    116.JPG.9558eb8056898253ab7732a17732f1aa.JPG

    The original securing screws were very ropy so Dad has made some more. They are cross-drilled so that they can be wired.

    117.JPG.a966dbf3f403e5a35917c30bcee6e536.JPG

    First one down!

    118.JPG.9a19a9890b5aacf1540346ac2d2b7284.JPG

    On the other side, the sprocket had been removed.

    119.JPG.eec8c900b289c71fc7084b1a68330cdf.JPG

    First job was to make up some new keys. Dad saw this coming and got some key-steel into stock. However, despite being labelled 3/8", it proved to be 10mm and won't fit!

    120.JPG.3b82dbf6b7ed89ef404476405a8d3938.JPG

    Dad has ordered some more which turned up yesterday. This is labelled 3/8" but is 5/8" this time! Some jobs seem to be unreasonably difficult!

  8. Yes, quite right! There is an option in the manual for an extended layshaft with gland and drive gear and a note 'see power hoist supplement' which, unfortunately, we don't have. Of all the bits in our collection, we have the remains of one complete lorry and that spent its life, after the war, working as a tipper on the Somerset levels. It is the engine and gearbox from this lorry that we are using. We met the grandson of the original owner and he tells the story of how his father and Grandfather went to Southampton to purchase the lorry after the war and how they drove it back to Somerset using only the oil side lamps for illumination and they kept blowing out! As they bought it Government Surplus, they must have fitted the pto as a later addition as I can't believe that the Army would have had it. It is a genuine Peerless part which the lorry acquired in its life so we thought it best just to leave it on there as part of the history.

  9. Well, we have just had a splendid weekend in Devon and have made some very satisfactory progress. Here is the first instalment.

    Gearbox was all ready to fit so we pulled it out and lifted it onto Dad's lifting trolley. It is fitted by pushing under the chassis and then lifting it up into position

    901.JPG.39ba5bc4c4550f251a643c9bc2702d0b.JPG

    904.JPG.fb89d21d603a3481b98a3fbf1b0b3ea8.JPG

    However, as predicted, the combination was too high to go underneath.

    905.JPG.9ea8c88d9ac904649db4f1d57a5281a2.JPG

    The solution was obvious in the end. Just jack it up and put it on stands!

    906.JPG.1a522d778bef02fee3f10a54d103de73.JPG

    We then took the opportunity to trim and fit the spacer tubes and dig out the bolts previously made by Dad.

    907.JPG.46e178be979a70e9eb1597039bd85f24.JPG

    910.JPG.ba3cf350c751aff2dda282a8295dd541.JPG

    The fun now was to align the bolt holes.

    911.JPG.e9269bacc18c78b9ae259c6c15cc3269.JPG

    A lot of fiddling and messing and with the help of a bit of rod with a tapered lead machined on it, we succeeded.

    912.JPG.2acb223fda421a74c9e57a138282472f.JPG

    913.JPG.cd4f341e26977d9f2ce6b215f855d535.JPG

    The rearmost bolts needed some spacers to lower the box into line with the half-shaft outer bearings but this was soon accomplished.

    915.JPG.5c02d74008ac2c87acfa677e6df52c1f.JPG

    Now it was time to connect the gearbox to the engine. Father had previously repaired the propshaft and painted it.

    916.JPG.5b0581cd31bb7772641ce7d77e5db8be.JPG

    The couplings have a felt oil seal fitted. This is contained by a pair of bronze castings wrapped around the shaft and contained by the outer cover.

    918.JPG.d3deb0a70c21334e25e9584971873623.JPG

    The felt is contained by a spring clip which we were fortunate to have.

    919.JPG.8590dee91ab242ffebd5d95ba2473341.JPG

    The bronzes were fitted and then the cover wangled over them to hold them together. This was something of a juggling exercise!

    920.JPG.14665c6385f2119095204456df5aec50.JPG

    Tim and I carefully held all the bits together whilst we juggled the shaft into position.

    921.JPG.5ffc182e525241c81a05a4978de87581.JPG

    The steel bearing blocks were fitted to the pins and the cover slid over the lot to trap it.

    922.JPG.ffde554a6a1a8e86320ce807d794d37b.JPG

    Four bolts (UNC this time) secured it with the cover carefully rotated to allow access to the grease plug inside.

    923.JPG.894a23443fa34f9ba6e4fc883cb000fe.JPG

    924.JPG.c1e03acf6c13fde4fed603b539caebb8.JPG

    And the other end with both grease plugs facing the same way!

    925.JPG.8dce4541581cabf82e5e2595492c6c8f.JPG

    We were then connected from front to back so it was time to add the pedal shaft and clutch pedal, again previously sorted by Dad.

    926.thumb.JPG.76e5810c714ffe6e602681a6bece675e.JPG

    We realised that we were missing the two UNS pinch bolts so Dad turned them up

    927.JPG.433feffbbac522da56ad380f3e094074.JPG

    Pedal shaft installed and the clutch works! I added a couple of Peerless greasers from stock just to finish it off.

    928.thumb.JPG.445210fa2d8db9f64c20a6684e0b781f.JPG

    929.JPG.68e1dfe7c58c06fe4510ca1707d6262d.JPG

    We had to try turning the handle and watching it all move. Very satisfying!

  10. Yes, finding that photo really made me smile. I just need to trip over the car at a rally now and my day will be made!

    Getting the box in is tricky because of the bracing bars on the sides of the chassis rails. As you suggest, Mike, I am planning to jack and pack the chassis up to give me the headroom. I think I need another four inches which is achievable.

    Something else I found time to tackle was the clutch spring. I found that I had to reduce the length of the hooks in order to slide the assembly  into position so I took your advice and fitted a jubilee clip to secure it. That gave me a lot more confidence!

    It screwed on with just enough bite on the thread.

    903.JPG.b7d94f89600652614252b8e7dd8c5aef.JPG

    Then it was a screwdriver under the clips to ping them off and we were done!

    I am hoping that the lining will bed in quite quickly and allow the cone further into the flywheel. I cut the lining as thin as I dare so I don't know why it protrudes so much. Anyway, we are now in a position to connect the box to the engine. The next visit is going to be an exciting one!

  11. We have just had a splendid weekend in Devon celebrating parents' diamond wedding anniversary. This is completely off-topic, I know, but bear with me. Father bought a brand new Austin Healey Frog-Eye Sprite in 1961. He and mother did all their courting in it and eventually they took it away on their honeymoon. Whilst my thoughts have been on the subject, I casually googled the licence number and amazingly, it still exists!

    801.jpg.f4fb35f4de966e3d2aa2efd425cef9bc.jpg

    I was unable to track it down in time for the party but we would love to see it so if any of you ever come across it, I would be very pleased to hear from you!

    To return to topic, the second half of the weekend was spent working on the gearbox! Tim and I started by fitting the replacement self-aligning bearing.

    802.JPG.d0f66ea729defe93c71c686be1bf3ab3.JPG

    The mainshaft was then ready to fit but it is a heavy lump and almost all I could do to lift it.

    803.JPG.c5d1e31d6518660d56d9689fa27bed51.JPG

    This was the point at which we remembered that the bearing carrier has a locating hole in it which should face upwards. More heavyweight wrangling needed here to get it onto the top.

    804.JPG.3c774bbff1ffdce32f7364999bb2d24c.JPG

    Then the input shaft was inserted over the new bearing.

    806.JPG.9ac19293214f062d57b87e8dd8b54fd5.JPG

    That was all satisfactory.

    807.JPG.bdf0065a7432508e7988975437a33944.JPG

    Next, the layshaft.

    808.JPG.009b6a39f11358e3e760946be4298108.JPG

    Everything turns! I squirted quite a lot of oil around but it was all most satisfactory.

    809.JPG.afa930d850150db86dd3fc0463807a1f.JPG

    Then the selector forks. Despite my repairs, there is still a lot of clearance around them. Will have to see how they work out.

    810.JPG.509530bb7075dce60416742e090b5785.JPG

    Dad has made up some new couplings for the selectors. They are left and rh thread. Now finding LH UNS taps and dies really is tricky so they have been made with 7/16" BSF threads as they are the same pitch as the UNS equivalent and only the thread form is slightly different. They still screw over the original selector thread so I am happy with the compromise.

    811.JPG.730840c03b66cad69b91bb6e486f6b8d.JPG

    812.JPG.18782f8cfc8888fb4a03ca3ababf9d5c.JPG

    They work!

    813.thumb.JPG.6bdde0d0a0dbcb02dc1e4ba55c8b6e91.JPG

    The nuts were all pinned and the felt seals were fitted into the carriers before screwing home the glands.

    815.JPG.20aed1db08e4f59a7d21946d2a066b13.JPG

    816.JPG.70e79850e66b23206c4d78f6481f48a7.JPG

    The drive coupling was cleaned up and fitted at this stage too.

    817.JPG.2492a19194572f4ad93ad32b5fee2585.JPG

    Along with the PTO gear. This gear will never be used by us but it is an original part that was fitted to this box so we have reinstalled it to keep it safe.

    818.JPG.419cc8144f1589b2484f73406f59139e.JPG

    The box is ready to fit!

    819.JPG.7621816eebc4e33ee0ca5679bbc2c63f.JPG

    We are planning the next visit to install the box. That will have its own challenges as it has to be lifted up from underneath but is too tall to slide under the chassis when on the lifting table. Something else to ponder on!

  12. We have done a bit more today although I was a bit slow getting going this morning. It is taking me longer to shake off work these days! Anyway, Dad has put a flat on the fan support rod and finished that off. The hole in the Y casting has a flat to locate with it and stop the fan rotating on a vertical axis.

    602.JPG.5dad50771f79da3252fe8922462487d2.JPG

    The rod is supported at the base by a casting and I have been making the pattern for that. It is mostly MDF with a bit of oak for the boss. That smelled wonderful whilst I was turning it.

    603.JPG.2d0b58dd0fc437264ef53632acd87c31.JPG

    604.JPG.dc70a6e69c24abd4563a7c224c73271c.JPG

    Radii created with Isopon and dressed all round with the Dremel. It is now in the paint shop.

    605.JPG.fa2f60436fa16df1000d2a5c5814e206.JPG

    The two missing support tubes for the gearbox bolts just need the ends trimming to fit the channel. I will do that next time I am down.

    606.JPG.4a7be971f291895d653272c12afd7d4a.JPG

    I did try fitting the clutch but could not get the spring tensioning nut to bite. I have therefore made some clips to hold the spring compressed whilst it is being fitted.

    607.JPG.93353fa3bcdbf9384bf541e8c1d73402.JPG

    I squeezed the spring up in the press and tried them out. They work fine but I have been advised to treat the arrangement the same way I would treat a live hand grenade!

  13. Dad has been making up the gearbox mounting bolts ready for the grand reassembly. They are actually studs and UNF at that. We are pleased about that as UNF nuts are available!

    501.JPG.85d6a353978241b58123805d2ac500fa.JPG

    502.JPG.57dd34cca2b4709ad1ea44a40cb98c20.JPG

    The bolts go right through the channel cross-members from top to bottom so tubes were provided to prevent the channels from crushing. Unfortunately for us, two tubes had gone missing at some time in the life of the lorry resulting in severe corrosion of two of the bolts, hence their replacement. In the mean time, Dad has cleaned up the two remaining tubes ready to fit.

    503.JPG.59f6c72d80429af59c594eb085213ce6.JPG

    504.JPG.1be3b779fdc957849b89371de05a9595.JPG

    505.JPG.858939985638406c8e2f7ac281210f73.JPG

    I have done as much gearbox as I can from here so my thoughts have turned to the cooling fan. Unfortunately, we don't have one so it has to be made up. These are the bracket mounting holes on the front of the engine.

    506.JPG.844db6b56a0c5ed7f4c464c850b3b715.JPG

    The Bovington armoured car mount is quite different so nothing to copy there although I did measure the fan and drive pulley diameters.

    507.JPG.101c6c664e07d13e5e15cd94096e2f30.JPG

    The Sandstone lorry has the same bracket mounting holes as ours but the bracket is an obvious later addition.

    508.JPG.53b769dcf08d6c61cd360f3aea25fa4d.JPG

    However, the Banfield lorry is exactly the same so that is the one to copy. I even found that we have the Y-casting in the heap so that has been cleaned up and fitted.

    509.thumb.JPG.0a8df743a08c3974716919e33b8efefa.JPG

    Just recently, I was given this fan by a great friend who thought it might do.

    510.JPG.658b8aef9649fa35b8b5288bc5aaf691.JPG

    It doesn't look anything like the cast fans we had seen. However, I remembered that the Wheal Martyn example had something similar but with only five blades.

    511.jpg.691484a99110ce30ef74450e13761496.jpg

    Then I found this picture in the collection which has a six bladed fabricated steel fan so we have precedence! The bracket is slightly different so I wonder whether there was a weakness there and the extra steady bracket was put on top later?

    512.jpg.1dd69623ca39e335be9eb624b9da07b8.jpg

    First job was to get it to bits. Heat and brutality as usual.

    514.JPG.f0859db49b2f6e114aac22cf5ca41805.JPG

    The drive pulley is mounted on a left hand thread which, very fortunately, I twigged before trying to unscrew it.

    515.JPG.77c9871e3e12d3cae23e7841a9b194e6.JPG

    Bearings might have fought again but I have bought new straight off the shelf.,

    516.JPG.bab04898444d13c6319f0728a7000afb.JPG

    The original spindle was mounted eccentrically to allow for belt adjustment.

    517.JPG.7be5a18620b509576db47e0b9867d748.JPG

    The fan was a bit undersize and one of the blades was broken. Also, the curve on the blades had been set so that it was a pusher fan and we need a puller so I took them all off and cut out some new ones.

    518.JPG.1a0d7a7909c4da86cb80cd190799659f.JPG

    519.JPG.a8e257fab48f53f73a90fa4486ed9ce9.JPG

    521.JPG.417d0482651faf4c80d10c8b84b984da.JPG

    Then I had to rivet them back on. I suspect that this fan was French as everything on it is metric. Interestingly, the six rivets on each blade were of three different sizes which was an added headache.

    522.JPG.fde227dcb9f8f3c85a732e76c337cc8f.JPG

    I set the blades to curve the other way and it started to look quite nice.

    523.JPG.e5ef6b173251f4a95ff755c2400db03b.JPG

    I sweated a ring around and it is ready for cleaning and painting.

    524.JPG.cb99eb588246628b283141ebb25299ff.JPG

    We need a new spindle of course and this was a nice turning job.

    525.JPG.42bfab168fad22e4bf9508d75d3a6f02.JPG

    Then bore and tap a hole through it taking care to keep the tap square to the spindle.

    526.JPG.6eeceb01ca638444a8b7266d75e9af7b.JPG

    Annoyingly, the spindle has and extra flange on one sideso I had to turn that up.

    527.JPG.064cff5b3682b2aef1c01607bc68f3c5.JPG

    Silver soldered and cleaned up ready for some paint.

    528.JPG.746aa7617e55f999d05cc101e13959c4.JPG

    Dad has made up the support rod.

    529.JPG.2a3c588c41e50bdb9ec8d0727b05bd7b.JPG

    I am currently pattern making for the base casting and hope to finish that tomorrow. We will need to think about the drive pulley as that is missing as well. Another pattern needed!

  14. There are four things preventing us from reassembling the box (apart from time!) and these are the selector forks, the mounting bolts, the bolt spacer tubes to avoid the channel crushing and the gear tooth damage. I have picked up the selector forks.

    As you may remember, the wear surface of all three forks was pretty rough.

    401.JPG.23578393ff1cdbaa834deb0e4aed0814.JPG

    I started off by polishing each with a piece of emery on a sanding block. Although this one is pitted, I reckon there is a enough metal left to create a rubbing surface so I have left it alone. One down!

    402.JPG.911715f8c9e7cdd75b8fde1e1f1bf6c6.JPG

    The other two were just too bad so I chose to machine out the corrosion and then silver solder some replacement metal into place.

    403.JPG.78a3e3bd7e56a2905b2f5a8a69bf446f.JPG

    The replacement pieces were secured for soldering using 6BA brass screws tapped into the parent metal.

    404.JPG.2ce1cd7a696cf05ea7a883512bd23a4d.JPG

    Ready for the heat.

    405.JPG.ca8400994cd1b07b0286e76934c92427.JPG

    First edge dressed off with a file.

    406.JPG.dd0a2a929f6bd6b4cdec1d824c7a500b.JPG

    Then clocked in the mill and dressed back.

    407.JPG.aa4f065914d4dd1f5617a05dd96b9d48.JPG

    They came out well and I was very pleased.

    408.JPG.b73d5322ab1ac9e7e2f093858a2a9682.JPG

    The drive spindles had had it, however with no thread left and a spare cross-hole for a pin drilled as a 'fix'. I turned up some studs as replacements.

    410.JPG.d180fba122bf0869babb0cf7e3899f8c.JPG

    After sawing off the original, I drilled and tapped the ends in the lathe. The challenge here was to get the threads straight in the ends.

    411.JPG.a631a001866e587877c5bbcfdd58b6f8.JPG

    Once started in the lathe, I resorted to a tap wrench to finish off.

    412.JPG.93c273312e81d5a4f3ec276a9ab34ff6.JPG

    The spigots have slots in the end to allow for adjustment of the actuator rods. The sleeves are screwed to the correct position and then a split pin is put through both to prevent rotation. Actually, I don't think this is a particularly good arrangement as the thread isn't secured and can fret as the selector is pushed back and forth which is probably what caused the initial failure. Possibly some locknuts should be given some consideration.

    413.JPG.8311bc0a3b1df27b30bd7a9e739eced1.JPG

    Set up ready to screw into place.

    414.JPG.917e21067c0eeef5755ca09bcab2a09a.JPG

    Selector rods ready for use! Another job ticked off.

    415.JPG.0145c83090abf3e83b17fc1cce44984b.JPG

    Dad is pressing on with the bolts and spacer tubes. More shortly!

  15. Thanks for your thoughts, Robert. You are right in that some hairline cracks are visible. I did try using a hammer and pin punch on the tooth edges to see if they would break off but they are quite firm still. Going in with a Dremel to tidy them up would be a good move though.

    I don't think these bearings caused the failure, Andy as they are all quite good. The two on the input shaft had lost their cages but were unworn. Even the failed self aligner was only rattly. All a bit of a puzzle but I am loathe to replace the pinion because of it. It won't ever have to work hard again so I think we should get away with a bit of remdial work.

    Steve    🙂

  16. Progress has been a bit varied recently and I haven't had a story to tell although there are things in the pipeline. They will surface soon but in the meantime, we have been doing a bit with Dad plugging away at all the rough jobs. With the box inverted, he has persisted with his cleaning up and started to paint the ironwork.

    300.JPG.96f8af0ad2c58d2d57443b9227fed933.JPG

    This flange was missing a nut, UNS of course.

    301.JPG.541668ffc06addebb0ea42399b91681f.JPG

    I slotted some that we had previously had made so that was soon sorted.

    302.JPG.c5501f1f9ae99b9dea6306f268724557.JPG

    The top face was missing 11 studs. again 3/8" UNS so Dad has made those up. Making studs can be very tedious.

    303.JPG.c0706978b24d4f9587a1b70086f19ffc.JPG

    Of course, he had to fit them upside down!

    304.JPG.81949ac144df8220975a1dc8676920ff.JPG

    I went down to Devon with the aim of reassembling the box. Alas, it was not to be but we did do a selection of tidying and preparation jobs. First was to turn the box over again and have another go at cleaning out the last few bits.

    305.JPG.47ecd4e2b89dd9ede1ff961d41269238.JPG

    Dad has been cleaning up the shafts with paraffin. This is the layshaft.

    306.JPG.db049ee1fb28b70a92ef0f1579d1ecbe.JPG

    Then the mainshaft.

    307.JPG.a6118541e57eba523f85abe6286e5e20.JPG

    It soon became obvious where the chunks of teeth had come from. I don't think they will cause any trouble so I had a poke to make sure there were no loose pieces and we will put it back as it is.

    308.JPG.d43d6e4423db8be2e9366be45630e743.JPG

    The input shaft nose bearng on the RH end is a double row, self aligning ball race. Once the oil was washed out, it became obvious that it was completely shot so we got on line to order a new one. Not the end of the world but it meant that we couldn't put the shaft in that weekend.

    309.JPG.e2a7e5daf4255115bcb62cf8eddbd426.JPG

    310.JPG.7afffb86f76c70fb41e3a8732b11d710.JPG

    The lid dropped beautifully over Dad's new studs and I fitted the repaired cover for the first time. At least that will keep the dust out.

    311.JPG.3dcb9e1b0e4cf3abd533d2a3154ff125.JPG

    Something I had been pondering over was the magneto drive coupling. The output on the timing case is simply two dogs like part of an oldham coupling but the only way to adjust its position is to remove the timing cover and increment the gear by a tooth at a time or in steps of 10°. This seems a bit coarse and also very inconvenient so I took an old vernier drive which had been previously machined and turned the back off before drilling two holes for the dogs.

    312.JPG.bb9a9c973f24ab9ef9862b9a6cd56a07.JPG

    313.JPG.2db76e489ae22b0478fcaa9a4ef93b85.JPG

    It actually worked quite well and I had only to dress the holes out with a file to make them fit.

    314.JPG.147c4507a8640bbbf24e50578196f1a1.JPG

    It went straight onto the dog on the right without altering any part of the original installation and we now have a fully adjustable vernier coupling.

    315.JPG.fc59f750fc66242a90e87aba4df9f3c6.JPG

    Next, we took a look at the selector forks. They run in a channel side by side but where they have been on the outside of the box, they are rather corroded.

    316.JPG.5bea93e52144b0581c69c481e272771c.JPG

    318.JPG.20594bdc00db1d92fc24b3e7002fb951.JPG

    Now I am wondering what to do with them and would value your suggestions. I had thought of cutting the ends off, screw extensions back in and then re-machining them. I could have them built up with braze or weld and machine them back or I could machine them back and braze a piece of steel into the cavity behind. Of course, I could leave them alone altogether and just use them as they are. Does anyone have experience of metal spraying to build the surface back up? There is certainly more than one way of skinning a cat!

    319.JPG.1c2ac5f93460b59d421c488211306cec.JPG

    The other interesting feature is the tubular connector which screws on the end and attaches the push rods. One of the threads is completely shot and needs replacing. 7/16" UNS again but to get the adjustment, one end of the tube is left-handed! I think they may end up BSF as that is the same pitch and I am not having taps and dies made!

    I have realised that we need to sort out the selectors and fit them to the box before the box goes back in the chassis so these are becoming pressing.

  17. Hi Al.

    Thanks for your comments. This is the first casting and a tester. Now that the pattern is proven, I am getting some more for several friends who want them. The silly thing is that I don't actually need one myself! Oh well. The pattern can go in the box with the others ready for the next time. I have made, or friends have made for me, 35 patterns for this lorry so it is quite a resource for anyone doing another.

    The next pattern is for the Peerless and is a lot simpler!

    Cheers!

  18. Well, now is the moment of truth! these are the cores produced from the core boxes. They really are nice.

    201.jpg.fbf89993347093dd159ebd9157b219e6.jpg

    And here is the casting!

    202.JPG.e23e9b4f5fdc564bdd61a6e29e264f75.JPG

    203.JPG.7d32b2c5f8edd9138de5b0c21f9d0485.JPG

    The core was made by gluing the two halves together before putting it into the mould. Even the removable piece came out OK.

    204.JPG.db7bc22db1ae6a43388a52c96909c25e.JPG

    And the one the other end!

    205.JPG.3f71f6044baa435886be8f6d57776b8c.JPG

    I am very pleased with the result as this was quite a difficult one for me. Many thanks to Adrian for all of his help!

    Back to the Peerless now.

  19. Well, I have been back on the gearbox input shaft so here is a progress report. I have obtained a very generous bronze blank, so big, in fact, that it wouldn't go in the lathe and I had to fret out a disc using a sawing wire. It took a while!

    101.JPG.9261404bee0c9b4577938896e71994e4.JPG

    Next move was to set the casting up in the four-jaw and turn off the old thread.

    102.JPG.657761ad980e74721d0e4064a5c43f6e.JPG

    That all went nicely.

    103.JPG.ed65393e78a82a885274702482c821f2.JPG

    Then I set the blank up and trepanned out the centre. That is a useful piece of bronze so I was not going to turn it into swarf!

    105.JPG.f7bec3f0c7720aa93d3a75f7a933d775.JPG

    I turned a rebate to fit the remains of the casting.

    And then silver soldered it together.

    I suddenly remembered that I had this. Dad picked it up for me but it has had very little use and is immaculate. I use it rarely but when you want one, you want one!

    It was rather remiss of me but I didn't snap the turning process. I had measured it up and reckoned that it was 5 1/4" dia x 16 tpi. thread to cut. I did that with a single point and then cleaned it up with a chaser. However, the casting wouldn't fit! On much closer measurement, I realised that it is 5 7/32" dia x 16tpi. so once I had cut a bit further, all was well. Peerless thread standards are a story in their own right!

    On removal, I was very pleased with the result. The metal colour is interesting. The ring was definitely bronze but looks more like brass. Fortunately for me it turned more like brass so the job wasn't too hard.

    As you can see, the new bearing is thicker than the original. Fortunately the bearings are spaced apart by a sleeve so I shortened that by the same amount.

    First bearing in and the oil shield dropped onto the shaft.

    It took a lot of wangling to get it all together but eventually, they were aligned.

    They were a lovely smooth fit but just a bit more than I could push. I don't like hitting bearings so the whole assembly went in the press which soon made short work of it. Very little force required, just a steady even push until it was home.

    Now to secure the bearings on the shaft.

    The change in length of the spacer meant that I could use a different tab on the lock washer which was fortunate as the regular one broke off in my fingers.

    The bronze cover sets the end float. I have no figures for what that should be so I simply did it up tight and then backed it off a bit before drilling for the locking screw.

    That was tapped 1/4" x 27 UNS to try to remain consistent with the rest of the box. Hopefully, it won't be my problem again!

    120.JPG.fc107a4f93580ba586fdf0dfdc9493af.JPG

    All together and ready to fit.

    The gland is not yet packed as Dad has the stocks of felt but that can be done in due course. Reassembly planned for the next visit!

  20. Yes, this one has certainly been a challenge and I wouldn't have got this far without Adrian.

    There are two things which would have resulted in such an awkward shape, I think. One is that 100 years ago, making things out of wood was very common and there were a lot of highly skilled people about. Casting was the standard process for making shaped parts and there was a foundry on every corner. They would also have had some really nice timber of exotic species available to them which would make things easier.

    The second thing is that, in my experience, not a lot of thought is given by the draughtsman for the pattern maker and moulder. One of my colleagues was drawing up a casting at work and whilst looking over his shoulder, I suggested that if he taper it the other way it would make it far simpler to get out of the sand to which his reponse was 'I expect they'll sort it out'. He had no interest or consideration for their problems. I have seen this in the radiator castings too. The Peerless bottom tank is a simple draw using one pattern and one core box, all nicely thought through. The Dennis tank has a plug and six core boxes, two of which are to simply provide an aesthetic feature. I bet the pattern maker cursed when he saw that drawing. I certainly did when I realised what I was going to have to do!

    There is one more pattern on the horizon for the Peerless fan bracket but that should be a simple one, fortunately!
