=================================================================

Here are a couple of shim punch dies I have made. These are worth 
their weight in gold when it comes to making clean punched holes 
in steel or aluminum sheet, cardboard or paper. The smaller one 
is simply a block of tool steel with holes drilled and reamed 
through then the block is slotted with a saw or plain milling 
cutter. Heat treat this and it will last forever. I made the 
small one 25 years ago. Better make several of these because 
others will want one to. 

Use dowel pin for punches. Grind a little stinger on the end so 
center punch marks can be aligned for precision punching. The 
dowel pins are already hardened. 

The other die was made just to punch rectangular holes. The other 
holes were added just in case. The upper part is cold rolled and 
the lower (die) is hardened A-2. It also has a deep throat for 
punching several inches away from the edge.
