I see your point, Rich.
The poster was talking about using his .50 cal. store bought patches in his .45 rifle.
I cut all my own patches - these are the tools used.
The old auto and truck bearing races with overly large ball bearings make good patch cutters, but cut only one at a time.
It actually does not take much time, though to cut 50 or 100 patches. The arch punches need something to cut against.
I have heard of guys using wood or lead, however, a block of UHMW or HDPE, 1 1/2" TO 2" thick works a treat and will last years.
uhmw- ultra high molecular weight (polyethylene)
hdpe - high density polyelthylene
This is the stuff used for butcher shot cutting boards & for conveyor chain tracks in mills. Here in Canada, only the white UHMW is legal for
cutting boards. This material comes in other colours as well. A block 2"thick x 8 1/4" x10" cost me $10.00. I've been cutting patches on it with arch
punches for 5 years now. I shoot fairly often as I still go through over 10 pounds a year now.
