Is this rebuilder a race engine shop or a "people motor" shop? Race shops
are more willing to do this kind of stuff, light flywheels are pretty common
to them.
I've had great success using a disc brake lathe and some caution. ( non TR)
My first step is to measure and draw a section of the flywheel then draw in
the cuts. The real trick is to avoid sharp internal corners, this is what
causes metal failure. Too little thickness is a no no too.
Most of the weight is removed from the edges, usually flywheels have a
obvious ring of metal to cut down. Removal of this ring is usually enough
for street use. Be sure to allow enough of a ledge to locate the ring
gear.
