Cutting Tball and button holes in Metal CP?
Crayola:
So I need to add a few button holes and a 2 1/4" trackball
hole to a metal control panel. Any suggestions on how to do this?
Would a hole saw work? I havent had good luck with hole saws
and metal. They tend to wander until they bite in. Usually where I
dont want it to:(

Greenlee hole punches make nice holes.
Crayola:
Got a good source for them? They seem kinda expensive.

Sorry no I don't. Also I have no idea what size for the trackball. You could find out how much a local machine shop would charge to punch the holes for you.
bkenobi:
You can use a hole saw or step drill for the buttons, but the trackball will be more complicated. Are you planning on having a bezel of some kind around it? If so, you can probably cut it with a hack saw and file it down to the final dimensions. If the edge will be exposed, I'd get a machine shop to do it for you.
