Re: [TCML] Cutting Garolite disk

Ok,
So I'm making a srsg and I am convinced of the primacy of garolite as the material to use for the disk holding the spinning electrodes. But as far as I can tell my sources of garolite will all provide square or rectangular chunks (eg - mcmaster-carr)

What's the best technique to cut a precise circle out of these square pieces?

I don't have a band saw...


Hire someone to cut it for you<grin>

The key is to make a fixture: Something to hold a pivot (drill a hole in the center and put a bolt/something in to serve as a pivot) and something to hold your cutting device. You can clamp a sabersaw type thing, or use an angle grinder, holding it against a rest, or even use a hack saw.

Eventually, though what you'll wind up with is a mostly round disk that you can clamp into something that spins it that is firmly bolted down. You can then use a rasp or surform or microplane that is held against a rest or block.
