Not a lot done today.

I finished machining the flywheel and spent an hour or so on the bench with some filing and a little application of miniature sanding drums on my Dremel to finish the spokes, and triangular spaces between them.

It seems logical to make the crankshaft and main bearings next, so now is the time for slotting the bore of the flywheel (which I should have done earlier), since that part of the crankshaft going through the bore will also be slotted for a keyway to match.
I re-mounted the flywheel in the 4 jaw, using a piece of 1/2" bar in the tailstock drill chuck to get it in the ball park between the jaws, then using packing to protect the rim, set it to run true on the shaft with a clock.
Some time ago, I made a cross slide mounted slotting fixture from a casting (College Engineering). It is pretty meaty, but different diameter end bars can be mounted to the piston.
This is the set up (the slotter handle is pulled clear) :-

Here is the "business end" :-

And the finished (slotted) flywheel.

The crankshaft next.
It is not a "built up" one - rather it is a straight shaft with a "fat bit" in the middle to carry the flywheel, and a crank disc secured at the outboard end. This too will be slotted/keyed to allow easier dis-assembly.

More anon, but thanks for all of the kind comments.

DeereGuy:
looks great Peter keep up the good work !

klank:
Benni, Bob - thank you for the encouragement.

William - did you make your own flanges etc.?
If so, what material did you use? That is something I am going to have to think about.
How did the tube plates go?
I am very interested in how you get on with the build.
Best wishes

Peter
