Last year I renewed the rear suspension 'lower arms' on a Focus diesel (19 year old but I intend running it into the earth). A kit off Ebay , the arms were German made & probably off same tools for Ford branded, however the bolts must have been "Property Class" 5.8 , but ISTR the PRC lowest cheese is more like 4.2 , needless to say I should have used a SO short series instead of a OEXL , stripped the bolt threads before I even got the torque wrench on (40+ round trip to Ford agent for proper bolts).

Old Bill Posted August 11, 2021 Share Posted August 11, 2021 I have been over to Grantham today to see CPA Radiators and pick up a set of tubes and gills for the radiator. They can do 15/16" dia and turned the lot around in two weeks from order so I am very pleased. They can also do 15/16" square gills if anyone needs them. 13000 gills which I now suspect is not enough! Oh well. 126 tubes. I had to try one! All is well and I just need to put the hours into the remainder. Must get on with salvaging the tube plates so I can return the lot to CPA for soldering up. More progress!

mammoth Posted August 11, 2021 Share Posted August 11, 2021 When you do return them for soldering can you get some pics of how they do it please. 2 Quote Link to comment Share on other sites More sharing options...
Old Bill Posted August 20, 2021 Share Posted August 20, 2021 I have been pressing on with threading gills onto tubes and have completed 111 with 15 to complete. Unfortunately, I am short of gills and so must order some more. It is an unfortunate break but at least it will give my fingers a rest! When I take the tubes back, I will see if I can get some pictures of the dipping process. Dad has taken Barry's advice and has spent a lot of time salvaging the tube plates. Fist job was to remove the bottom tank from the chosen core. Looks like the mice managed to get inside the tank! He then attacked the tubes with the disc cutter. This rad had been buried next to one of the Peerless chassis somewhere down on the south coast. As a result, the core was very rusty and full of filth. The plates don't look too bad. He attacked the muck with a nylon brush in the drill which was quite effective. A few odd gills remain soldered to the plate so I will have to get them off later. The soldering is curious. I wonder if those tubes at the edge were a repair job at aome time? All cleaned up and ready to have the tubes drilled out. Dad is coming to visit soon so he will bring them up for me to finish. Should save a few quid in brass anyway! Steve 🙂 2 Quote Link to comment Share on other sites More sharing options...
Asciidv Posted August 21, 2021 Share Posted August 21, 2021 I might be inclined to put a blow torch on them, melt the solder and then just tap the remains of the tubes out. A job for your under cover black smithing facility, where there is plenty of fresh air as we wouldn’t like you to catch ‘fume fever’.! 2 Quote Link to comment Share on other sites More sharing options...
Old Bill Posted August 21, 2021 Share Posted August 21, 2021 Thanks Barry. Might be worth a go. Looking at these photos this morning, I have just realised that there are ten more tubes in this plate compared with the one I counted before placing my original order! Will have to get some more tubes as well. Oh well. That's a job for later. I am on Dennis radiator castings today! Steve 🙂 2 Quote Link to comment Share on other sites More sharing options...
Great War truck Posted August 31, 2021 Author Share Posted August 31, 2021 I had a bit of spare time so i cleaned up the valve caps and put a first coat of red on one of the blocks. 1 Quote Link to comment Share on other sites More sharing options...

Old Bill Posted September 11, 2021 Share Posted September 11, 2021 A bit more progress on the Peerless. Dad has continued painting the cylinders. The valve guides remain to be reamed and new valves obtained but after that, they can go back on the engine. Dad has been to visit and brought the radiator tube plates with him. We decided to see how easy it would be to just melt the tube ends out and found, much to my surprise, that it was effortless. Once warmed up, the ends could just be tapped through. I turned out that they were not a close fit in the plate at all but were really quite sloppy so there were no problems. A quick dressing back afterwards followed by putting a 'W' drill through to clear out the gobs of lead and they are ready for final assembly. I am off to Grantham again on Monday to pick up the extra tubes and gills. Once they are assembled I shall go again to deliver the kit for final assembly.

Old Bill Posted September 15, 2021 Share Posted September 15, 2021 My trip to Grantham was successful and I picked up the extra ten tubes and 3000 gills. They are now all threaded and ready for another trip to deliver them for soldering. 136 tubes and 16000 gills with a few left over. All threaded by hand one at a time. My fingers are sore!

Old Bill Posted September 19, 2021 Share Posted September 19, 2021 (edited) One of the jobs we have been doing in parallel is to take a look at the clutch. This is a cone clutch with the female shape machined within the flywheel. The male part is an iron casting with a lining. As you will observe, the lining has seen better days. Interestingly, the lining is attached to a steel band, bolted to the casting. Father removed the lining ring and had the centre sand blasted before painting both. He removed the lining from the steel band and found that it is of quite interesting construction. It is, in fact, a leather band with plugs of cork inserted at regular intervals. The chances of us finding such a material are slim so we have elected to simply replace it with leather. One of my lorry friends came up with a piece of leather for us, the right thickness and just big enough. What you can't see is that it has been stored in a very dry environment for a very long time and was absolutely as hard as a board! Mark, our leather working friend, was contacted for some advice and he suggested painting it with Neatsfoot oil, letting it soak in until it would accept no more. Dad bought a pint and I started painting the outside. I couldn't get inside as it would not unbend, initially. However, after a week of treatment, I managed to get to the other side and carried on. Eventually, the sheet absorbed almost the full pint of oil that we had and had softened apprecialy. You still couldn't wear it but it was flexible enough for our purposes. I cut out a template so that when cut, it could be wrapped around the conical liner ring. Half an hour with a Stanley knife saw the strip cut out. Dad has now taken the strip home to rivet to the lining plate so we are still making progress! I am delivering the radiator components to Grantham tomorrow for solder dipping and soldering into the tube plates.

Old Bill Posted October 6, 2021 Share Posted October 6, 2021 We are still doing battle with the wheels. One is still attached to the chassis but Dad has been working on the other. The wheelwright has had a look and stated that this wheel isn't bad but needs new felloes. We need to prepare it and then deliver it to him. Dad has spent a lot of time knocking out bolts. They are an interesting variant of the coach bolt. They are all a boit ropy so Dad has turned up some new ones (9/18" dia, just to be awkward) from some M16 bolts. The brake drum is not very well either. An attack with the wire brush has shown that the surface is too far gone and must either be skimmed or replaced. Fortunately, we have a spare in the collection and some attention with the flap wheel showed it to be serviceable. So, we have to get the old one off. My best find at Beaulieu this year was this pin spanner. Perfect for removing bearing nuts! This wheel still weighs coming on for a couple of hundredweight so we lowered it onto blocks using the chain block. Then we tried to knock the drum off by hitting it between the spokes. Not a hope so out with the propane. Some further knocking cracked the joint and two days of hitting it have moved the drum an inch where it has stuck As neither of us is really up to sustained hammer work, we have given up and are now ordering up the steel to make a puller. Once the drum is off, the wheel can go to the wheelwright. Then we have the next fight which is to get the second wheel off the axle. I shall be glad to see the back of this job!

Every dimension on this lorry is a strange one - I turned the heads of the M16 coach bolts to the reduced diameter shown and rethreaded them - they are countersunk into the wheel and the residual dome on the M16 bolts after being reduced fits very neatly into the existing countersink on the wheel - so thank you for your offer but I think we can leave them as they are without them looking too funny!

mammoth Posted October 7, 2021 Share Posted October 7, 2021 With regard to the steel band around the wheel has there been an attempt to remove it and is there any sign as to how it was manufactured such as a welded join? The 1911 Dennis needs a new pair of these wide bands so I will be watching with interest. Quote Link to comment Share on other sites More sharing options...

What we understand from the Wheelwright is that the steel band is cut to get it off and then the cut is welded up again when the wheel has been repaired and is ready for the band to be put back on! Sounds simple! I have not noticed an original joint in the band but I will look again. Quote Link to comment Share on other sites More sharing options...

On Dave Engels YouTube channel he commonly cuts these bands on buggy wheels, but it is normally so that he can shorten them and re-install them tighter.

As a kid I recall driving past a seamless ring rolling mill somewhere near Sheffield and my dad explaining the process to me. (He worked for David Brown, who use forged rings as the starting point for some of their gears) I have seen variants where the mandrel is pushed through a solid billet, too.

andypugh Posted October 7, 2021 Share Posted October 7, 2021 It wasn't this company, but they might be a useful source: http://www.rolledrings.co.uk/ My impression is that such rings are a product with low setup costs, and so they might actually be affordable in low volumes.

Old Bill Posted October 22, 2021 Share Posted October 22, 2021 We are in the process of making a puller to get the brake drum off. In the meantime, Father has been pressing on with the clutch. Once he got home, he tried wrapping it around the band. Fortunately, we had got the curve about right. Then he drilled the holes through. We were a bit suspicious of drilling leather but he tells me that it is fine if you just let the drill take its time. He did have a practice first on an offcut though! After trimming to length, he fixed the leather with copper brake lining rivets. It all looks very nice but Dad tells me that the leather looks a little thicker than the original. The question is should we just try it or should we attempt to true it up by turning in the lathe? We haven't played this particular game before!

Asciidv Posted October 23, 2021 Share Posted October 23, 2021 I suppose you should see how well it sits in the cone of the flywheel. If it is proud by a long way then 'thinning down' on a lathe is an option, but I doubt if any of us have turned leather before. Be the first and tell us all how easy/difficult/impossible it was!
