FreeChex on the way.

Team.

I have one of Charlie's gas check makers on the way to the land of the Long White Cloud (NZ). Now I am on the scrounge for suitable material. Unfortunately not one of my neighbours has an copper guttering...............[smilie=1:

Jeff,

My brother was interested for a while in stained-glass work, where the pieces of colored glass were fitted together and lead or solder was used to attach the pattern. I recall that he wrapped the edges of the glass with strips of copper sheet and it was those wrappings that were actually attached with the solder. You might check and see if anyone offers supplies to the stained-glass craftspersons down your way, and see if they have the sheet copper. It must have been fairly thin to be able to be bent around the glass for a tight fit without breakage.

Jeff,

I make my own gas checks and I use aluminum cans, but be ware not all cans are the same thickness. The way that I calculated the thickness of the material that I needed was as such:

Grove dia of Bore+0.002= Finished seated check size

Finished seated check size - boolit shank dia./2 = needed material thickness

Here is the numbers for my Mod 94 30-30

0.309 + 0.002 = 0.311
0.311 - 0.287 = 0.24/2 = 0.012 thickness needed

I found an aluminum beverage can, that the side walls are 0.006 thick, so I make a double layer gas check that seems to grip the boolit shank nice and tight, and seals off the base pretty well. It is a bit time consuming but it is cheap.

The simplist way, is to get a rolling mill.
Before I became a jeweler, I had no clue how to reduce thickness on metals. There are some at fairly low cost, that would work perfectly for makeing gas checks.
Copper flashing, at either 20 guage, .032 or 16 guage, .051 can be rolled down without much effort to .012, or smaller. Jewelery supply houses that will deal with the public also have sheet stock in brass, copper, German silver, aluminum.
I have several rolling mills from Harbor Freight and Salvage. They are made in India and are good enough for making sheet stock for gas checks. I also have several Deitsch 130mm rollers, but we won't talk about those. We will never need that accuracy for a gas check.
This whole thing is essentialy simple. Roll out some copper, anneal it, use it. Even copper pipe can be split and rolled out.

I went to the local hardware store and bought a piece of aluminium 300x900mm which should give me in the region of 2000 checks. Cost $16.00. Thickness is 0.019 only 0.002 thicker than Hornady checks so I will end up 0.004 over size which should not be problem. Rather too big than too small.
