Re: [TCML] Cutting Garolite disk

The most precise method would be to turn it on a lathe.
Assuming you do not have access to a lathe either, a circle cutting jig for
a router or jigsaw works very well.

Even a large hole-saw will work, just watch your heat.

Another option to consider is the propeller style gap.
Check out Terry Blakes page if you havent already.
