Came up with the Idea if trying to make my own gas check maker, and the dame thing works. I will admit, I copied the idea from the basics of the gas checkmaker by Pat Marlin. This layout is for making 35 cal. gas checks, but the same principle will work for just about any caliber.Here's what you do.
1 get an old Lee resizing and decaping die.
2 starting at the top of the die where the decaping pin screws into the top of the die, drill a 1/2in. hole all the way through to the bottom of the die. Now you have to stop about 1/4in. from the bottom, because there is a carbide insert in the bottom that you have to punch out and the drill bit won't cut through it. Use a lathe to get a precise hole lined up throught it. Now face off the bottom of the die so you have a flat bottom on the die.
3 take a hack saw and cut a slot at a slight angle at the top of the die about 3/4in. down from the top of die, all the way through to about 1/16in. past the 1/2in. hole inside.
4 make a 1/2in. punch pin and braze weld it to a shell holder. Now you have a punch pin that goes up and down inside the die casing.
Now using .010in. aluminum or copper, you are making gas check blanks.
5 take a block of steel and drill a 1/2in. hole 1/8in. deep. Then using the same block of steel, drill a 3/8in. hole all the way through it.
6 make a steel press pin .450in. diameter
7 lay gas check blank into top of steel block with 1/8in. deep recess.
line up everthing and push press pin down into block and WALLA; you hav a gas check
Now I think I have expressed everthing in detail: Any questions?
