Oooohhhh........ Pete! :bugeye: ....... I love it, when you Lekky Lads, talk dirty..... :thumbup:

I eventually, got my head around the hot cap, sealing/ retaining problem.
Finding a piece of correct diameter, tube. (It just happened to be bronze). I silver soldered a ring, to replace the original flange.....
Recessed, the new holding flange.......
The cylinder/ spigot, protrudes through, by "a couple of thou'". To make a positive location/ seal, against the bulkhead.......
Held on, by three, neater than original, screws........
Secure......
Thanks for looking in!

I hate to see engines, held onto their wooden bases using, obvious, wood screws. I prefer engineering screws. Button heads, look ok.
Or, in this case. Countersink.......
The two rear fixing holes are now, under the bearing pedestals.
Had to drill a central hole.......
I drill, clearance holes, for the screws.
Underneath. I counter bore 15mm deep. The same diameter, as the nut's a/f measurement.
I can then pull the nuts, captive, into the recess......
Thanks for looking in!
Stilldrillin:
New, improved, crankshaft location.....
The two uprights, are made from 6mm thick angle iron. Cleaned up, square, on the mill. Dowelled and screwed in place, from underneath the base plate. Allowing removal, and accurate replacement, when necessary.....
The two, outer bearing housings, are a sliding fit, in the uprights. Held in place with slidelock........
The inner bearing housings, slide over the smaller diameter.......
Butting against the upright. Also, held with sleevelock.......
Should be much more effective than the wobbly, original assembly.
Thanks for looking in!
Stilldrillin:
The crank assembly, is finished....
It cycles nicely. No tight spots.......
The flywheel, is next. At 7" dia. It's a little on the large side, for a mini lathe......
The original bore was unsuitable. So, I drilled out, oversize, and plugged with a piece of m/s. Held in with the ever faithful sleevelock.
The rear boss, held in the chuck jaws, has been machined nicely true to the rim. Allowing me to set the rim running, within a thou'.
Now, I'm starting to open up to a 10mm dia bore. Hopefully. Perfectly true to the rim......
We'll see......
