The tab punch

The tab punch
Punch for putting holes in the cell tabs

Made the punch and die for the tab punch.
It has an adjustable hole position stop, and can punch the copper and aluminum tabs consistently.
I modified the dies used to make the MIMA display bezel, but it still took most of the day. Have some fiberglas and special bolts coming tomorrow.
