Been thinking about what it would take to make some good sliders/protectors. Specifically exhaust protector(s) and frame sliders.
I've been looking at R&G exhaust protectors and sliders for my bikes, and the costs add up for what is essentially some plastic, bolts & bushings. Then I got to thinking I could get a block of polyoxymethylene and tool it, throw in a pipe clamp & high-temp rubber and I've got a perfectly good exhaust protector.
Something like this:
It seems like there are two candidate materials that are both accessible & affordable (I don't have a lab here, so no custom plastic blends for now...)
Delrin (polyoxymethylene)
Pros: tough, reasonably accessible, easy to machine, available in blocks
Cons: expensive, might get soft @ 200F (potential problem for exhaust protector)
ABS plastic
Pros: Cheaper than Delrin, widely available, easy to machine
Cons: Mostly available in sheets/beads f/ injection molding but not blocks, quality among types could be questionable
Fabrication:
Basically three options: hand tooling, injection molding & 3D printing. Hand tooling is the logical first step. Injection molding would be great for reproducing consistently + much less manual labor. 3d printing would be an ideal option, but the concern is materials, and of course cost.
Anybody tinker with this idea before? I'm thinking street use, but if a solid product comes out of it then who knows.
The big question now is on materials: what plastic is affordable, tough, easy to tool, isn't too strong or too weak/brittle. Next question is on high-temp rubber, specifically for exhaust applications to prevent melting and provide padding.
Shot in the dark, but thought I'd see what you all thought.
Thanks,
Gabe

Unless that slider is mounted to the exhaust can mount and has a metal hoop for strength inside of it, I'm betting it'll just act as a stress point and crack the CF with the quickness in the event of a crash.

Interesting, hadn't considered that. I don't have CF on my bikes, but I guess denting on steelmight still be a problem under the same principle. Increasing the surface area might improve things without a complicated frame mount.
Didn't someone on this board sell these at one point?
We have 10 3D printers that can print ABS. On a long pavement slide, don't think ABS would stand up to the abrasion, which is why Delrin (a trade name) is widely used.
I have R&G sliders on both axles and the engine cases on the Tiger. Exhaust has a metal cover. Already saved my swing arm, axles and forks in a track day slide on a rainy day.

Justin made these before...

Cool I dropped Justin a PM just for the heck of it.
Definitely looking like Delrin is the way to go, especially for tooling something.
