Find some smart Kid who can copy a old one with a 3D Printer. Lots of schools and universities have them. Billy

My guess is the wad finger you show was injection molded, so tooling must exist somewhere.
Teflon bar stock is available and it might be pretty simple to turn the shape, then slit it. If you remember back 50 years ago, the wad finger in the 600 Jr. press was made of brass, not the red plastic everyone replaced it with. I know how that part was made, but knowing that, and having the funds to make the punch press tooling are miles apart. I think turning a piece of teflon is the shortest route. And yes, I'm aware of the fact the burning, or melting teflon generates toxic fumes. McMaster-Carr has Delrin rods, which would be a good material. https://www.mcmaster.com/teflon/multipurpose-plastic/ |

I was thinking the same thing about using PTFE. We machine it alot at my job. Kicking my self because I just threw away about 25 ft that my job threw out years ago thinking I would never use it. If molding delrin is the way to go for sure. I have designed several molded parts out of it. The volumes are pretty low to justify a mold but I have seen some temporary molds produce excellent parts for runs under a couple thousand. You can probably get a temporary mold for around $1000-2000.

The guys who make the 8ga MEC tooling have tried the 3D printed route and the parts were much to fragile. My thought was machined out of PTFE tube stock or Dylrin. A injection mold would be way to expensive. We are looking at a lathe turned part at $15.00 to $20.00 each.

I may be able to help you with your Mec part. I have a friend that specializes in composites and adhesives and has 52 years experience. He lives in Oswego county but his shop is in Wolcott. I believe the part can be rubber molded at a reasonable cost per part. Call me tomorrow after 4PM if interested. Craig Budgeon (315) 524-7853

Why not use UHMW
