Yonky
When I said more expensive, I was only figuring the cost of the aluminium for the gas checks.
I bought Aluminum Flashing from Ace Hardware.
Amerimax Home products. Roll Valley Flashing.
Aluminum
Standard 0.014" thick It measures at 0.014" thick.
Part#
68104 4"x50' $19.07 Special order.
68104 4"x50' $19.07 Special order.
cut strips 1/2" wide.
Get 8 or 9 of the .30 caliber gas checks per 4" strip.
50' = 50' X 12 inches per foot = 600 inches = 1200 1/2 inch strips.
1200 1/2" strips X 8 per strip = 9600 gas checks for $19.07
$19.07/9600 = 0.2 cents each.
I now cut the strips at 15/32", but 0.2 cents each is close enough.

Aluminium coil the correct width and thickness from Yonky at
www.coilandfoil.com
Prices are as follows:
1/2" wide x .014" thick x 50‘ long aluminium $5 per coil, maximum of 3 coils per small flat rate box, shipping is $6.00
3 coils X $5 per coil = $15 plus shipping is $6.00 = $21
50' = 50' x 12" = 600 inches x 3 coils = 1800 inches for
$21
I was getting 8 gas checks per 4" strip from aluminium flashing, thus 2 gas checks per 1" of coil.
1800 inches X 2 = 3600 gas checks for $21
$21.00 / 3600 = 0.58 cents each.
slightly more expensive.
I do not have to cut the coils into strips.
Hornady gas checks are about 3 cents each.
I have learned a lot just in the short time I have owned and used the .30 caliber Checkmaker from Pat Marlin.
Soda pop cans have not worked for me.
There is the price of the paper cutter and the work to cut the aluminium flashing into strips. Sometimes I do not cut the strips to the correct width and either I have to trim the strips to get them to fit or the strips are too narrow and I get partial disks punched.
I plan to try the aluminium coils from Yonky. After using them I could give my opinion of the three aluminium materials: soda pop cans, roof flashing and coils.
I would also like to try the copper coils.
