I've been cutting and bending 22 gauge galvanized on a 30" 3-in-1
sheet metal machine. It struggles with 22 and 24 would be easier.

Does the struggle leave you with a less-sharp bend, or what? What
width stock are you bending?

3/4" angle 24" long, and the bend is tighter at the ends than in the
center.

Thot so.


I corrected the angles by clamping them in a home made pan
brake as a vise and adjusting the angle with a rubber hammer and this:

I have the cast iron version of that from eons ago.


They are corner reinforcements for an insulated plywood and foam box
for the Alpicool C20 freezer, whose insulation is inadequate in a hot
car.

Bueno.


I made the 4' pan brake to form white aluminum flashing to cover my
exterior window frames, which I rebuilt in PT wood that doesn't hold
paint well. The brake isn't nearly stiff enough to bent 22 gauge steel
but it clamps it well.

When I was completed and was adjusting the brake a neighbor stopped
by, asked what it was, then when I told him, said I could borrow his
10' Tapco siding brake.

Rat bastid. He waited, eh?
