MOTM

>Do punches work ok on 1/8" thick MOTM-style panels?  The catalog says up to
>.079" thick aluminum.

It can probably do .079" aluminum with a 5,000lb press -- do you have one
of those?? :)  Regardless, painted .125 is about twice as thick as
unpainted .079.

If I had to cut a 1" hole in 1/8" aluminum, I'd use a hole saw.
