just read an old post about using a single hole paper punch to get perfect holes in self made gaskets. what if the holes you need are bigger? a really cheap way to make holes, right up to 1/2" is to get some shell casings from your local gun club (MAKE 100% sure they have been fired....even the primers pack a punch). im not completely sure on these numbers.....but they are close. 22 cal = 3/16, 25 cal = 1/4 , this goes up to 50 cal = 1/2 with many common calibers between, matching many common bolt sizes. lots of places will give you these USED shell casings, and they do make great gasket hole punches.
i stress again tho......make SURE you confirm that the PRIMER has been used in the casing before you start tapping on it with a hammer.
