Citroman Posted May 1, 2019 Share Posted May 1, 2019 Are the pipes smooth, no rust pitting? Quote Link to comment Share on other sites More sharing options...
Minesweeper Posted May 1, 2019 Share Posted May 1, 2019 Pitting - I think that really is the problem! These pipes are not as smooth as we would like to see and a softer rubber pipe connection would probably bed in much better! Quote Link to comment Share on other sites More sharing options...
dgrev Posted May 1, 2019 Share Posted May 1, 2019 Regarding the molasses rust removal, a word of warning. Spring steel and high tensile bolts turn to a brittle honeycomb consistency in my experience. How that double spring you have, survived is a mystery to me. Quote Link to comment Share on other sites More sharing options...
Grasshopper Posted May 1, 2019 Share Posted May 1, 2019 In the past, I've had to double-clip soft silicone hoses where vehicle-side pipes have been pitted. Seemed to do the trick, although probably not the aesthetic you want on this vehicle. Quote Link to comment Share on other sites More sharing options...

I think I would try a couple of turns of self-amalgamating tape tight around the stub before fitting the hose. It might not work, or it might prove impossible to fit the hose over the top, but it's quick to try and then quick and clean to un-try if its a failure.

Asciidv Posted May 1, 2019 Share Posted May 1, 2019 I have usually found that the old style Nestle brass clip just does not grip the hose tight enough. So I compromise on authenticity and use a modern wideband clamp sold on ebay for 'turbo' applications. I fit them with wing nuts and paint them black to give a token old appearance. The most important thing though is that they keep the water where it should be! The picture shows the clamp in the natural stainless steel finish. 1 Quote Link to comment Share on other sites More sharing options...

Put the tape on the pipe dry and well stretched, then lubricate with soapy water when pushing the hose over. You just need a strip where the clamp will be. Robert G8RPI.

Hoseman Posted May 4, 2019 Share Posted May 4, 2019 (edited) On 4/30/2019 at 10:01 PM, Gordon_M said: I'm not a hose expert ( Hoseman, where are you ? ) but there's only a couple of possibilities. Either you have too big a size difference between the OD of your connection and the ID of the hose, or your hose is too hard / rigid. I suppose it could be a combination of both. A thinner, softer hose would be the easiest fix. After all, I expect the pressure in the system to be just the hydrostatic head and a couple of PSI. I'd guess you are using industrial strength hose that would pressure test to hundreds of PSI and is probably twice as thick as it needs to be. Ask everybody else with similar vehicles what they are using? I will try my best to help . . . . as mentioned above, maybe a too rigid hose. Has it a steel helic inside? (Wire support) then you need single bolt hose clamps to secure. Too modern for the Thorny. swap for a fabric braided hose section, the helix is only there to prevent hose collapse, a short section like this doesn’t need it, so just a fabric braid is fine. Normally in 1m sections. Give me the ID and I can source for you, but try an industrial hose supplier rather than a hydraulics one. Cheaper too. Other option is a smear of clear silicone on the pipe when you put the hose on. Have the steel pipe sections got a swage on the edge? To secure the hose and the clamp. PM if I can help in any way guys, my pleasure after all the years of ‘entertainment ‘ you have given us!

Old Bill Posted May 6, 2019 Share Posted May 6, 2019 Very many thanks for all of your thoughts. We have certainly got some things to try there. One of the castings is a bit pitted but the other two are new and polished by ourselves. They might not be perfectly round but they are smooth. The hose is 'Radiator Hose' with no wire braid core. I know this as the word 'Radiator' was written along the side in bright orange letters. It took ages to get it off! It wasn't tremendously tight but it did need pushing on. The clips we have are a bit on the narrow side. On the other vehicles, we have used a standard worm drive clip until the joints have taken up and then replaced them with brass ones of the period to look right. The leakage did slow down as it warmed up. Another annoyance to address! We'll let you know how we get on. Steve Quote Link to comment Share on other sites More sharing options...

Great War truck Posted June 30, 2019 Author Share Posted June 30, 2019 We took the Thorny out for a quick test run on Saturday and as nothing dropped off or otherwise went wrong we took it to the Wessex MV club gathering at Haslebury Mill today. A 40 mile round trip. The lorry performed almost faultlessly and made no issue of some of the steep hills on the way there and back. This was marvellous as we were a little cautious as to whether sleeving the engine might have reduced its power. Here we are on the way back through Axminster: 6 1 Quote Link to comment Share on other sites More sharing options...

Great War truck Posted June 30, 2019 Author Share Posted June 30, 2019 Thanks Richard. it was a very satisfying moment. Hard to think back how far we have come with this. Steve said it was like driving a new lorry. A couple of little snagging points that we still need to do, but we are nearly there now. From all the team we would like to thank the readers of HMVF for their suggestions, positive feedback and support. We really appreciate all of your comments and we really appreciate how you keep coming back to check on progress. I will add some more photos later on.

Great War truck Posted July 5, 2019 Author Share Posted July 5, 2019 Here are some photos of us putting up the complete canvas for the first time which we were very happy with. Jim from Allied Forces made it and it really is an excellent piece of work. Thanks Jim. We then took it out for the road test on the Saturday. Started off with a one mile run, followed by two miles, followed by a 15 mile run. All very good. 4 Quote Link to comment Share on other sites More sharing options...
Great War truck Posted July 5, 2019 Author Share Posted July 5, 2019 On the Sunday we took the lorry to Haslebury Mill which is a round trip of about 40 miles. The Thorny performed wonderfully and we were very happy with it indeed. It attracted a great deal of interest at the mill. 5 Quote Link to comment Share on other sites More sharing options...
Citroman Posted July 6, 2019 Share Posted July 6, 2019 How did you the signalling on the road, brake lights, direction indication? Quote Link to comment Share on other sites More sharing options...
QL Driver Posted July 6, 2019 Share Posted July 6, 2019 As far as brake lights, I think a vehicle like this is so much slower and has such inferior braking performance that lights are unnecessary. For indicators, presumably it’s traditional hand signals only? With our steam wagon the driver will use the “highway code” signals, and additionally the mate will stick his arm out for left turns. Quote Link to comment Share on other sites More sharing options...
Minesweeper Posted July 6, 2019 Share Posted July 6, 2019 That is exactly what we do with Hand Signals. Turning left does concern me just a little as I wonder sometimes if a driver in a following car would be alert enough and would understand a passenger's arm sticking out on the near side when perhaps he would only be looking for signals on the driver's side. Quote Link to comment Share on other sites More sharing options...
QL Driver Posted July 6, 2019 Share Posted July 6, 2019 To be honest, my feeling is that so few people would be familiar with hand signals that it’s essentially an irrelevance; the most experience people will have is with bicycles and so duplicating that is a good idea. Of course, the time that signalling left really makes a difference is when changing lanes, and you can just have the mate look out and make eye contact with drivers.
