John,
Thanks for that link.
Irving's book was 'the Bible' when I was a teenager trying to get my old Royal Enfield Model G (1948) to at least complete a trip without stopping.
I lost the book when my parents moved house whilst I was in the army. Now I at least have a PDF.
Dave. :D
OKTomT:
Thanks guys
Pete one of the first things I did after welding the cases was install hollow dowel pins. you can see them in some of the pictures. The cases were bolted together and put in a four jaw chuck. Then the main bearing journals were bored.
John thanks for posting that book its going to be a big help. I was surprised to see the connecting rod in that book was made from parts welded together.
Next up is the cylinder. At this point I am leaving the original design. I bought a box of sleeves at a flea market and when I got home I looked in the boxes some of them came with liner, piston, pin, and rings. The one I am using is 3.25 bore. this and a stroke of 3.75 should give me a little over 500cc :scratch: notice the 4 ring piston and dome on top. The cylinder was turned from a piece of dom tube 5' od 3' id bored and the sleeve pressed in. tom
Pete.:
Yeah I see the dowels - right in plain view - now. Dunno how I missed those :)
RotarySMP:
Great project. Are you also planning to fabricate the frame for it?
J. Tranter:
What size tube or pipe did you use for the crank case please?
