I have the need to wrap a plywood box with thin aluminum sheeting.
The box is 4ft X 4ft. I need to bend the edges of the sheeting about
1/2" along the 4 ft edges in order to wrap the entire box.
Anyone ever rig up a makeshift brake out of wood in
order to accomplish this? I don't want to spend $400 and up for a
factory made break if I can help it. Thanks.
