    Belzona is excellent, and used in heavy industry. MoD use it and I have used it successfully in all sorts of applications. regards Richard

    To be honest no, it was a very interesting exercise and I understand more about the system than I did before. Unfortunately I am so busy, give it a week or so and the information will be overwritten in my little brain. It will still be there but I will have to concentrate damn hard to retrieve it. I have made notes and identify the various wires for future reference so that should help. The engine loom is all tided up and the engine has been started several times. There are some aspects that I am not happy with but once the steering box and final drives have been connected to the gearbox the whole lot can come out for spraying and then any concerns addressed.

    Part of the Pitmans range of motoring books, written by an ex ASC ( Sergeant ?) and full of useful information about the dawn of Mechanical Transport generally and Thornycrofts in particular. Originally 2/6 d ( arf a crown ) I bought mine at £80 (Ouch) but have found it invaluable and have read it cover to cover except for the hard sums ! Tomo

    BRDM, Vehicle electrics, what can you say. One day perfectly good vehicles will be useless because of them. I find it hard to believe that our armed forces buy vehicles that are reliant on electrics. Rick, One step forward, two steps back, The oil pipe was a stupid mistake on my part, my son connected the pipes together and I didn't check them. Still I have made a modified version of the connector and I am waiting yet again for supplies, god this area can be frustrating some times. Simon, Thanks, to be truthful after emptying the oil over the floor I was rather issed off but the worst part is that I know that I can't buy the items that I need locally so I have to rely on the internet. Rely, internet, Ha Ha Ha...…….. Jon

    Evening All, This is a long one but where to start. The petrol tank is finished and the new engine is in place, so now on to the electrics. I have an engine, a wiring loom and two ECU's, one engine and one gearbox. The wiring loom doesn't fit the engine, the concept of plug and play has gone out of the window, the wiring loom is the wrong loom for my engine ECU. The ECU requires one yellow plug and one black, my loom has one yellow and one blue plug, that doesn't fit the ECU. As far as I can ascertain, the loom is for a 3.2ltr, my engine is a 3.6ltr. What to do. In a moment of shear depression, I did think about trying to find the correct loom but then I thought, what the hell, I will rewire the whole thing. The Haynes manual is like the proverbial chocolate tea pot, so after a lot of searching on line, I found a wiring diagram for a 3.6 of roughly the right vintage and begun chopping. This is definitely not a job for the faint hearted, it involved altering, and I am not exaggerating, about 80% of the wiring loom, even the colours are different. Eventually after two days of chopping and adding I was getting somewhere but where I wasn't sure. Even the simple items had either more of fewer wires. At last I turned the key, nothing. There was, in the loom, a group of about 10 wires that were all permennant lives, in other words they were live even when the ignition key was turned off, something I don't like, so I cut them into individuals and traced where they went, ignored what I didn't think was important and connected the remainder, just one. After my initial test or failure, I realised that I needed a second permenant live to the ECU, this was connected and I tried again, the ECU fired up along with the fuel pump. I now had two of the main items, a cranking engine and fuel but no spark. When the expert, had decided that I needed a different engine, part of his reasoning was that this engine didn't require an ignition amplifier. I spent hours looking for a wiring diagram that didn't require this amplifier but I couldn't find one, so I rang the expert. Now amazingly he told me to ignore what he had told me and fit an amplifier. This should give you some idea of what I have been up against. The amplifier was ordered and duly arrived. The wiring diagram showed 5 wires, the amplifier had 7 connections and the plug had 7 connections but only one of the wire colours in the plug matched the diagram and that was in a different position in the plug. Again, back to the internet but I couldn't find the relevant diagram. What I did find, was a thread where a bloke had wired in his amplifier incorrectly and attached pictures of the connections and their relevant place in the plug. There's a but, the plug had 7 spaces but only 3 wires were connected. The wiring loom that I have, originally only had 3 wires, of course the colours didn't match but I decided to attach these 3 wires into the plug as per his picture and blow me I had a spark. Today I reassembled the cooling unit into the hull, connected everything up, filled the cooling system, attached a temporary fuel tank and pressed the starter. After the fourth attempt it started, what a sweet note from the exhaust, well for 30 seconds and then the oil pipe to the oil cooler shot off and emptied 8 litres of oil on the floor. Bugger. I have to admit that I have shortened this story so that you don't consider suicide. Jon

    If are looking for liners, I use Westwood Cylinder Liners, they have stock sizes or will make to your spec. Sometimes you might find the right diameter but slightly longer, my machinist cuts them to length before fitting them. Then you bore to required size. regards, Richard

    Put them in the bore when (I assume Mike) has bored the cylinders for you and the liners are in place. If they fit well go for it, if they don't make some new ones. Young James Allison seems to have cracked making rings round here. I believe turns them to size plus a magic number (which isn't big by the sounds of it, but seems to be a trade secret). Puts a junior haxsaw through them, springs them out using a spacer and waves the gas axe at them to get them to a certain colour. Then lets them cool and gaps them Then they are good to go.

    All pistons are marked 30.C on the tops. This should mean +30 thou. Size C, which was the only oversize piston available post war. In fact the pistons measure just under +20 thou. and have been turned down to match worn bores, with their top corners rounded off to avoid the step , ( just visible in the previous pics.) This apparently was common practice in the day. During the war no oversize pistons were supplied and the Army ended up casting their own at Base Workshops to prolong the life of engines. Info; "Auriga" Book of the Thornycroft p.87-89 The plan is therefore to attempt to fit liners to standard size A and turn down the pistons to match. This all depends on the remaining wall thickness, which is due to be measured with an ultrasonic gismo by an ex Williams racing engineer on Friday. Exciting stuff this isn't it ?

    I managed to get another good hour tonight and was able to mark out the 2 rear side panels. I cut the first one and test fitted it and it looks good, it will probably need some fine adjusting but I was happy to cut the second one. Thanks Andrew, I am slowly working out how thing's fit in relation to each other. Peter.

    Blyth Battery Goes to War - May 18/19th I took both the "Jessie" and "Faith" to Blyth Battery at the weekend, one on each day. The main report is on my Dodge thread here - ( http://hmvf.co.uk/topic/15260-1944-flying-control-dodge-wc51-the-story-so-far/page/24/?tab=comments#comment-447735 ). Next mission, "Lanc, Tank and Military Machines" at East Kirkby over the Bank Holiday weekend.

    As previously mentioned, the Battery gun emplacements now have replica Mk VII, 6 inch naval guns installed and look much better for being occupied! Both emplacements had re-enactor displays, but in one, a gun crew ran simulated ranging, loading and firing displays. The port of Blyth can be seen in the background of the last gun image. At the end of the car park, looking in this direction, there is also a search light building.

    I removed the front panel again to drill 6 holes and then put it all back together. I then fitted the last 2 angle irons and welded them in. There is a tray to make and fit across the inside the front lower hull plate along with some fuel line clips but I need to get over to Alastair's to borrow the pattern. Next job is to finish the sides. Peter.

    Our plans are moving forward,nearly a full day on our two G3L's, and the very welcome sight of Stevo on his first test ride out on the newly built M20.Nearly 30 miles to get to us, so a reasonable test.It sounds lovely and starts first kick,been a while since I rode an M20,a very different ride to the Matchy !

    It has been a good week for the purchasing department. There were a couple of good purchases from eBay including a job lot of Rotherham's of Coventry parts and we found quite a lot at Beaulieu autojumble. There is at least one item for each of the vehicles and quite a lot for stock. The Dennis car hub cap is just for the display case (not quite enough to start a project, yet).

    I had (still have) a cracked crankcase on an Austin 7. Also aluminium. I had another but changing the crank, cam etc seemed so much of a ball ache, i used some fuel tank sealer painted on the inside. It has never leaked oil. And is currently doing service on my chummy. It was the white stuff that Paul Beck used to sell.

    Now I am happy with the front panel alignment I have started to fit the angle iron to the inside of the front panel. The first 2 are straight forward lengths of angle iron that run from the top corners of the lower front hull plate to the outside edge of the body with 3 holes in the front and 3 in the bottom, I need to remove the front panel again to drill the holes down through the bottom of the panel's. There are then 4 angles that run top to bottom of the front panel that are welded to angles on the lower panel. I have got the centre 2 done these angles also mount the instrument panel. Next I need to do the outer angles which run along the inside edge of the fuel tanks and hold some of the fuel tank brackets. Peter.

    I am finally happy with the alignment of the front body panels. When I started I went from the back edge of the original front lower hull plate and I should have started from the front edge throwing everything out by ¼" causing the gaps at the front corners. I sorted things out by slotting the holes in the front side panels. The rear hole are covered by the centre panel on the outside and the body support bracket on the inside. The front holes will be behind the tracks and don't stand out so I will live with them. I also took the time to get the front panel to sit better. This involved trimming the front edge of the front side panels. I had the front panel on and off 4 times today and although not heavy it is large and difficult to line up and get the bolts in. I need to take the front panel off again in the morning so I can drill 6 holes. Peter.

    The next task was to remove the cylinders complete with pistons. The water jacket connector was already terminally damaged on this engine, so when the 5/16 W fastening bolts broke off too, I was left with no option but hack sawing through the remains. Fortunately I have been promised a spare from a 'parts' engine in Yorkshire. Thanks John. The Regimental engine lift is proving a very useful item and after some experimenting with lifting strops, I found the best method was to pass a thin strap, doubled over, through the upper water cavity as shown. This gave a nice balanced lift. The cylinders were deposited onto my work bench and as they laid over ( under perfect hydraulic control, ) a surprisingly large quantity of old sump oil ran out over the bench and the floor ! This had obviously been added by the previous owner to help free the pistons. Thanks Ian. Fortunately the L.A.D. has a an amply stocked rag bin and I was able to clean up the mess before anyone noticed !

    Once the public left at the end of the day, and most of the re-enactors had gone to eat, I took "Jessie" back to the Halifax to do another photo shoot of my own. The view through the back window of the Jeep was edited to create the effect of the Halifax engines running. Unfortunately, due to the position of a small wood near the T2 hangar, the strange orange evening light of the sun set was shielded from the Halifax. Sunday began with an atmospheric mist over the airfield and another opportunity to catch the Halifax in a different light. The mist soon burned away to give a very hot day, with little wind to provide cooling. Both days saw a good turnout from the public and everyone seemed to enjoy the weekend. The museum was very pleased with the way it went and have confirmed the dates for 2020. Further images can be seen on the event page of my Jeep website - http://www.sacarr.co.uk/mymvs/events/2019/elvington.htm

    Evening, There's not alot to show you really, as i have been altering my previous work to accommodate the new, later engine. I took a trip up north to meet Rick, Eddy8men and what a really nice chap he is. The reason for my journey, was to pick up the muff couplings for the steering box drive shafts but oh, how I would love to restore some of his toys. Thanks again Rick, for the bits and the chat. Whilst I was talking to Rick he introduced me to a new word " Imagineering" so I have been doing a bit myself. One of the frustrating parts of this project, so far, has been trying to decide what to do for the final drives. On the way home, being bored at the wheel, I was thinking about all the options thus far and it looked like I would have to sell a kidney to finance the relevant components, then seeing a vehicle on the road and cursing a lot, I had an idea. A quick search on fleabay and low and behold, someone was scrapping such a vehicle 3 miles from where I live. I haven't done any accurate measurements yet but from a tape survey, they seem to match up, almost too exactly and the ratio looks to be 5.5 : 1. Sunday morning, my son and I, took a Land Rover stuffed with every tool needed for a right bugger of a job but ended up only using a couple of spanners, a ratchet, highlift jack and a big bar. Two hours later they were in the workshop waiting to be washed. Jon

    I can't believe it is 5 years ago today, since "Hope" returned to the road after my two year rebuild from a wreck. The GPW was actually completed some time before, but as my vehicle insurance was renewing on April 16th, it made sense to start the policy when my other vehicles cover began. As first found During rebuild The first drive. Complete and out after a first drive since it died on a Texas farm.

    Thanks Lofty - that's very kind! It is an added bonus for us that others are enjoying the story and also adding information and advice all the time - and that is very much appreciated. Doug - there have been some old bits of paint and we have looked very carefully to see what colour it originally was - but it is all so tired and faded that we have not been able to say. I do not think that there is any paint left on the wheels at all, now. Not much help! Tony

    Looking at my copy of the the J Type spares list dated 1924 there appear to be 3 rings at the top (all part No 66217) and the ring half way down is described as 'locking ring for gudgeon pin' (60958). "The Book of the Thornycroft" by 'Auriga' dated 1923 is interesting as it describes design revisions and corresponding new part numbers. In respect of pistons Feb 1915 saw the height above gudgeon pin increased 1/16" and depth below increased by 11/16"; oiling groove omitted, six 9/16" holes added below gudgeon pin. June 1916 skirt thickened up. Further in, there is a section on over hauling and over/under size parts. It would seem that there was a later type piston referred to as a 'scraper ring type' (71713) which used different compression rings (70920) and a scraper ring (71714). The gudgeon pin is of the floating type. As far as "balancing" goes, what is balanced with what? In performance engines the weight of the reciprocating mass is balanced against the rotating mass of the crankshaft using counterweights on the crankshaft. It is more easily understood with single cylinder motorcycle engines, and the choices between balancing primary and secondry forces are more obvious. The Norton Commando was a good example of these choices at play as the engine was designed with a lower primary balance so the the motor would oscillate in the vertical plane on rubber cushions so the the secondaries could be more refined so your fingers didn't tingle as in the Triumph.
