I suppose you have to create that jig to hold the dowel pin at a very specific position then drill the back of the flywheel?
My concern is how easy it would be to drill that chunk of metal.
A machinist has the provision to do the same job multiple ways depending on which machine is available.
This is very easy mill work and the flywheel is cast steel or iron which is easy to machine.
This is not a difficult job.
Most mills can store the X Y axis of a point.
It is not rocket science to then flip over the flywheel reference it on center and EXACTLY drill the center of the stored X Y points.
On a lathe, the points could be marked off the rotational center circle and then locked and drilled with the correct drilling attachment.
Again nothing difficult.
All you need is the checkbook to cover the work.
Over 90% of the cost will probably be setting up the job, with a small fraction of machining time.
If it were mine, I'd forget the dowels, surface it flat, install it, bolt on a clutch, and drive.
