Clever checkmaker

Life is too short to spend all of your time cleaning and organizing. On the other hand, life is too short to spend all of your time looking for stuff in the debris field. I guess that is a conundrum. Spindrift, how do you order from this guy?I own a Free Chex tool but it is on semi permanent loan to a good friend and I really like the ease of use of this guys device.

If I understand correctly, you can order on this web site


Just to be clear, I have never used or seen this tool myself, neither do I have any link to the man making them. I was just impressed with what I saw in the video

Dima Prok is the guy that makes the gas check maker and he has posted plans on the web on how he makes them. I don't have a link to the plans, but I do have a copy of the plans that I downloaded.

I finally found the plans over on CB and also noticed he's making the check maker for sale.

He must not want to make you or anybody else any Dies, quoted @ $90 in May 2018. Hardest part to make is the bottom piece with the slot that's cut for the Aluminum strip. Again, you can download the plans for free.

I still have a couple of Keith's Lee die blanks which would be perfect for the top part. A other member loaded me up with plenty of round bar drops a while back, will have to see if there's anything tough enough to make the bottom piece.

tough enough to hold that edge after cutting and folding aluminum 10-K times.
I still don't know why a little lube isn't used on the flat stock.

At the casting bench in the sky. RIP Bret.

Probably because no one researched it. Kerosene/Diesel is often recommended as a lube for aluminum. Bet it would help.

That's still about $50 more than I'd pay. And by the way, those plans I linked to aren't (at least as far as I can tell) Dima Prok plans, they are plans by a CB member by the moniker of IDZ. He should be given the credit.

Yes, IDZ's drawings and instructions are the ones I'd follow, he explains exactly how to make different cup-forming mandrels for different thicknesses of material and includes the measurement formula. It's common sense but very nice to see it laid out.

I'm wondering if the slit were at a slight angle, say 3-5°, would it cut the discs more easily than punching through the whole thing all at once? Would that tend to stretch the material and make an ovoid disc? The burrs from shearing help the check bite the bullet shank, maybe it's best that they are uniform all the way around.
