I was looking at Harbor Freight for some hole punches for making gaskets when i had this idea.
Go to Home Depot or Lowes and get iron pipe close nipple with the ID as close to the hole diameters you need.
Next cut off the threads on one end and grind the outside edges down till you have a decently sharp outside beveled hand punch.
Then you just place the gasket material on something like plexiglass or similar to act as a cutting pad. Place the punch where you need it and hit it with a mallet to punch the holes. Clean the slugs out by shoving a screw driver down the inside.
I will be getting some and will make a set and post up pictures when i get a set made.
