  1. 1914 Dennis Lorry

    Ben, are you going to use a sheet metal shrinker to take the ripples out of the turned over lip on the roof or do you have some other plan? I have been looking at one of these for years and could never decide whether they are any good or not. Does anyone here have any experiences of using one of these?

    When I have made up oil pipes for pressure gauges I have always just soft soldered the nipples on and not silver solder like what Ben has just used. On this era of vehicle ( pre-WW1 ) was there a preferred method? Looking forward to hear the engine start. Engine starts seem to be coming thick and fast now!

    Well, there is Ben, Me and you, so we only need 17 more to make the numbers up!

    Timing diagram from a 1920’s 4 cylinder SV engine of 3 litre capacity. Still not radically different.

    When you compare the Thorny with the Dennis, the valve timing looks very similar. The duration of the Thorny exhaust period is shorter but the difference is located equally with respect to the Dennis exhaust timing. Is the problem really valve timing after all?

    This is the timing diagram for the 4 litre Dennis sidevalve engine of the 1930’s.

    I have just realised why the delay. The films must have been Super 8 and have been sent away to be processed......

    Steve, does this mean you are going AWOL from Dennis Eagle or was it always your plan to have extra time off? As one of the previous posts said, you have the whole world waiting with baited breath to hear it run for the first time. Tim should have set a live streaming on Facebook so we could have watched it as it happened.

    The offset crank is a beautiful piece of work, with lovely fillets into the bosses. Almost too good to go onto the Thorny!

    Andy, if you remember from the Dennis thread Tony bought a Black and Decker 'Power File' on my recommendation to clean up the steering wheel casting. He managed to blow it up in less than a day!

    Steve, a definite improvement! However, isn't it tedious knocking all the slag off ready for another pass? I know so many jobs would be easier with different equipment and you just have to prioritise what you would buy next, but I think top of your list should be a 250A MIG welder.

    Marcel, I like the way how you achieved parallel sided splines accurately. I assume that you just milled away the smaller 'leftover' spline. Although I gain satisfaction from making parts with the 3D printer and the Wire EDM machine, I know it would not be anything like the pleasure that you get from making parts like this on machines from the same period as your vehicle. Andy posted a link to a video of a man setting up to cut some splines. There were 6 or 7 edited videos showing the whole process. I think I was set up and cutting splines in the time it took for half the first video to play, so there are some compensations.

    Gordon, you do have to compensate by machine adjustment for the type of material you are eroding. However I don’t think the Thorny would really notice as we are only talking about a thou or two. Wire erosion is incredibly accurate. The party piece trick is to make two parts size for size and slot them together. Here is Steve’s spline gauge with the matching inner part. Only if you look closely by the arrow can you tell that there are two separate splined components.
  14. WW1 Thornycroft restoration

    Spline Gauge Mark II ! The 1/4" slots for the splines are now 5 thou. wider and there is a 15 thou radius on the inner corners of the spline.The wire diameter is 0.25mm so there is a natural 7 thou radius on the outer, inner corners of the actual wire cut part, which isn't shown on the drawing.

    Lovely to have the original registration for it. CC1720 has a nice 'ring' to it. It puts it apart and makes it stand out from all the 'SV' registrations!
