We have several Unipunch tools... punch several 1/2" holes in 1/4" mild
steel at once, with a 60 ton Minster punch press. The 8AJ 1-1/4 list here
is rated for .4375" holes in 1/4" plate:

I am thinking of making a machine that will punch a .375" max hole in
..250"
mild steel. First of all I need to find out how much machine this will
take.
Will a 50 ton hydraulic bottle jack have the power? Who sells the dies?
Can
the dies be made?

Thanks,
Bill
