Thank you Dave  :ThumbsUp:

Next up were the various brass electrodes for the distributor. I did consider making the centre electrode from graphite but didn't have any suitable material. The output electrode were turned just using a parting tool. I made a spare as they look like something for the swarf Gnomes  ::) The rotor electrode was hand filed to shape and superglued in place. Finally I set the phasing between the cam and the rotor arm and drilled and tapped the fixing hole. The RT was used as it was already fitted and is a good way of holding round things.
Best regards

Thank you all for your support  :ThumbsUp: Zephyrin, I have found the small Proxxon drill and mill very useful. I have a very small workshop they will sit out of the way on a shelf when not in use. As my main machine is a combined Lathe and Mill I can do small milling jobs without having to convert from lathe to mill and back again. I am currently investigating the FD150/E micro lathe so I can make small bushes and adaptors whilst I am in mill mode.

Next up were the clamps for the distributor cap. These were made from 8mm aluminium bar drilled 3mm and then half milled away. I was quite impressed at the accuracy of the two parts  :) Two clearance flats were then milled on the same side. I then faced the water pump gears to size, giving about 0.1mm clearance to allow for thermal expansion (found the hard way on the horizontal engine  :( ) The key way was cut with the broach I made for the previous pump. Now I need to make a 2mm stainless steel key.
Best regards

Roger

Thank you for your interest  :ThumbsUp:

Finally a bit of workshop time on this. The water pump drive key was milled from a length of 3mm stainless steel and the ends were rounded by filling. When I assembled the gears they didn't turn smoothly and on close inspection the force of cutting the keyway had stretched between two teeth  :( I tried again this time with the gear held in a 14mm collet as I did for my horizontal engine, all ok  :)

I had decided I didn't really need to flange the water inlet as things were a little tight so I Loctited a stub of brass pipe in place. Finally I used my new toy to put cones in the end of some 4mm grub screws for the tappet adjusters starting with a centre drill and following with a 3mm drill.
Best regards
