Thanks for your support and interest Guys.
It's starting to assemble up nicely.
Next up the slide bar bearings.
This is what I'm making them from
Spent a bit of time measuring up the assembly to check the size to make them to. The inner bearings are different to the outer, when I was drawing the engine up I couldn't see how to line up and fix the inner bearings, so left the ? hanging now that i've got a few bits around me the solution is quite simple just screw them to the bearing housing with a counter sunk cap screw, I can get alignment by ensuring I drill the hole for the cap screw central, and drilling the housing on the same centre line as the bearing, the outer bearing will be tapped with four M2.5 threads and will be bolted to the outer housing
Milled the bearings up in pairs.
Drill and counter sink the inner bearings
Next up the slide valve attachment made from a bit of square mild steel bar, faced off and tapped and parted off in the lathe, then milled and drilled using my little vice.
This is where they go.
Then with them fitted measured up the eccentric straps for the forks.
The fork were made from some round brass bar with flats milled and the fork cut with a 3 mm slot drill.
Next using the method John showed us but solder the fork to the strap.
This is how they fit.
And how the assembly is looking.
I've got to strip it all down now and drill the bearing housing for the slide bar bearings and I need to modify the crank a little so that the fly wheel fits.
I'll be more or less ready them to try it out:- fingers crossed.
Cheers
