Has anyone used one of those combination punches (driven by a hand
wrench) that will make a 3.5 or 2.25 inch instrument hole in sheet
metal? How thick an aluminum panel will it go through? Were you happy
with the result? I'm thinking of fabricating a replacement instrument
panel and want it to look good.


They will make a clean hole in any aluminum you are likely to use in a
panel. I have punched 1/8" steel, no problem.
