After watching Chiefs video on using a Tandy press for punching holes, I thought I might be able to re-purpose a grommet press I have (fleabay $30).
I unscrewed the top die and tried on a Tandy mini punch tip, it fits. Game on!
I cut 2 pieces off a cutting mat to the size of a scrap piece of brass I had.
Removed the spring loaded center piece from the lower die.
Set one piece of mat over what was left of the lower die and pressed down on it leaving
an imprint of what I needed to cut out. This becomes the holder.
I super glued the 3 pieces together with the brass in the middle and set it on the lower die.
Voila, an easy hole punch for when many holes are needed.
TODO- drill and tap a hole in the brass for a screw & washer to keep the sandwich in place, if needed.
