Very nice build :clap: :clap: :thumbup:

Thanks Dave, Saw, Murray (and apologies for not acknowledging previously).
I went on the search for a flywheel 'How to' which I thought I'd seen on HMES only to be redirected over here to a Bogs post on the subject which uses the same engine flywheel as an example. http://madmodder.net/index.php?PHPSESSID=282779f14615aa033c7f5d9e8cca14a2&topic=871.0
I haven't read it through yet but do recall his preference for collet mounting, which means I may have to comply.

Looks like you've caught :proj:
At the rate you are progressing Pete, you'll have it up & running before the next Club Meeting. :clap:

Thanks Murray
I don't think I'll get that far and its not about trying meet any particular deadline. However, I find the "eating an elephant analogy" works for me. Focus on the part being made one at a time, work out the plan of attack, do your best and then move on to the next. If you go wrong work out a recovery strategy or start again.
There is an example here
The plans have the base tapped 4mm for studs for the stand offs. I'm using BA throughout and ended up drilling 4BA clearance with the intent of using bolts, I then found the bolt heads would get in the way of the cylinder. I had a number of recovery strategies, including start again. The drawings require some of the other holes to be counter bored so I counter bored these holes and then turned the heads down on some 4BA cheese head screws. I think its now neater than the original not having stud ends peeping out of the holes.
So having a pile of half completed parts is just fooling yourself you aren't a production line and its unlikely that your workshop is equipped to have a number of things on the go at the same time. Of course 'bling' is done at the end, repeated assembly dis-assembly while fitting parts will just mess them up so they have to be blinged again.
Doing it this way means you progressively get to the end. I think this model has different 45 parts I think I've done about 12 so just over a quarter of the way through.

Armed with a copy of the relevant bits Johns "Making a flywheel" post I headed to the workshop. It was all pretty painless really and I was pleased with how it went. However, I had formed the shape of the disk too deep and the 8 mm drill wandered off on the outer ring on one side of the spokes. I pressed on to the end by way of making it a test piece/prototype to prove it was what I wanted
A new blank was hacked off tonight ready to do another one tomorrow.......
