Not a waste of time... for me at least. Once you get everything worked out, I'll be buying some parts so I can get my two Equalizers back running Well, one worked last time I messed with it about 2~3 years ago, but the other needs a reg rebuild.

Dang, my company has a CNC router for cutting thick fabrics/thin rubber. It's mothballed right now because it can't cut the thickness of rubber we use....

Doc.
I wouldn't take silence to mean lack of interest. I'll probably need a couple of your first round of parts but the trigger seal is the vital part. If you're going to be selling those I'll be buying a couple of each.

-I actually have no idea how you'd go about cutting a VM detent out of sheet stock in any kind of a production setup.

I don't think you can "hot wire" urethane- I tried using a laser cutter, and it just melted. (And, unfortunately, stayed melted.) A stamp or punch would be the traditional method, but making a punch that complex would be costly.

I do have a CNC router with a high speed spindle, but I'm honestly not sure how well this stuff would cut- and I'd still have to set up some tooling for it. I'm already wasting money on this little project.

-I'm just waiting for the material. As I said, we found some, but the shop only wants to sell me a 100-pound roll, for like $350, and that's just a little more than I want to spend on this little project, since it's already kind of a wild goose chase.

There's only gonna be like, what, eight people that will buy a seal kit? I feel like that lady that made the Barbie type dolls in that old episode of the Simpsons- she and Lisa made a new feminist type doll, but were out-marketed by the established Barbie thing (Malibu Stacy? It's been a while since I saw it.)

Finally one little girl picks up one of Lias's dolls, and Lisa says if we just geyt through to that one little girl, it'll all be worth it. To which the lady who had them made says something like "Only if she pays forty-six thousand dollars for it."

You can add 1 more if you get all the seals in
I've been wanting to pick one up for a While ... I might pick up the sell kit before I pick up the gun ... And it wouldn't be the first time

Doc, too funny man!

I recognized the color. It makes great 12 gram seals in Carter's odd changers.

Haven't tried a 12-gram seal yet, it's probably perfect for that, depending on thickness, but it's kind of on the soft side for a reg seal.

It's also pretty thick- it'd be perfect for VM detents if I could figure out how to cleanly cut it economically (it's a shame my laser won't cut it) but anything thinner than that and it's tough to cut down smoothly.

However, I found a sort of polyurethane 'putty' that produces parts that are around 70A-80A durometer when cured. I made a quick-and-dirty mold in Delrin for the trigger seal, and made several sample pieces:



They seem to work very well, and during testing, have held pressure for several hours without blowing out. I just need to make a proper mold, and practice getting the very stiff and sticky material- like honey left outside in January- to fill the mold without a lot of air bubbles and the like.

Stand by, we're almost there.

Doc.

Well, looks like I need to hunt down the old equalizer, just for the memories!
