I just bought a 7" round dial from timesavers which I want to prep. It's roughly 1/32" thick steel that's painted. I wasn't planning on using grommets but if the end result is not up to snuff I have no other choice. I'm guessing it's not possible to punch these so I'm left with drilling. Would I use a step drill bit and drill to an undersized hole and reek it out using a grinding come stone with a Drexel to widen hole to size to prevent paint from chipping? Also what size hole should these be for the 3 winding arbors required?
