Thanks for all the positive comments about the award. The Transport Trust award scheme has really helped out so I would recommend it to people for next year.

 

I have taken this photo to better illustrate the pulley arrangement. The bronze bearing extends from the timing case quite a long way (to around 1mm from my pulley hub); without knowing this it looks like there is a massive length of unsupported shaft. The pump pulley is still quite a way from the pulley hub (a little over 2"). I have not run the engine since connecting this drive up.

I decided to buy a new tool to help me reduce the length of the universal joint hub; an expanding mandrel.

Using the lathe and chucking on the male tapered portion I drove the sleeve into the hub until the hub was tightly gripped and supported the other end of the mandrel with a revolving centre and faced the hub off to length.

And could then try the hub in the jaw to check the fit.

I reamed the hole out in the other universal joint until I could drive in the pin.

Then put the bronze blocks in place and measured the overall length.

It worked out a few thousands of an inch too long to fit into the socket so I lapped the blocks down on some silicon carbide paper. Then I was able to wrestle the fairly heavy prop shaft into place.

The rear joint needs a leather gaiter to keep the grease in.

The front universal joint was bolted up and split pinned.

Although the rectangular brackets for the ignition timing transverse shaft were functional, they offended me every time I opened the bonnet so I removed them and shaped them using the milling machine and file. Finally I drilled oiling holes with a centre drill.

One of the parts I still need to make is a wind screen with a wire edge. I have never done this before so decided to give it a practice. I started by folding up an edge around a piece of steel plate using a hammer.

And then continued to form it around the wire with a hammer.

I will be using 1/8" diameter rod and 0.9mm steel so I have ordered a 5mm ball end slot drill to make up some forming tools.

 

That's it for this week. Hopefully we will go for a little drive over the next week.

Many other tasks got in the way this week; the lorry went in and out of the garage a few times but never under its own power. At least the prop shaft has rotated several times. We adjusted the transmission brake up a little; we can still push it on the flat and it easily stops the lorry on the slope of the yard. It always seems a good idea to get the stopping sorted out before making them go.

As the sign writer is booked in, I have been concentrating on getting the remaining beading fitted. Another task is to get the hoop fitted to the back but it needs to swap garages with the 1908 Dennis where there is extra height and enough space for the sign writer to walk all the way around.
