Custom Bits made from Bullet Proof polycarb material- See through!

Nothing a threaded insert can't fix though.

This is true.

Yea thats what I was thinking. Even if the carbonite threads a little bit rough you can Loctite a metal Helicoil in there, which will make it even stronger. There has to be some way to overcome this issue. Maybe some special process of heating it prior. If we can not come up with a contact for help there is one way to find out. I bet this guy making the parts has had some experience putting threads into some pieces? Either way I would like to give it a try on a few parts. If anyone else does make sure you share your experiences.

It's doable, I'm assuming a simple press fit threaded insert with some epoxy mixed in would be fine, however I would not want polycarb bulks as they would flex which would mess with the gear mesh inside the diff. Aluminum is the way to go for bulks imo.

Edit: Or you could easily just use a simple hex nut on the other side, but that can get sloppy if not done well.

I've tried a few... Every time the heat from tapping causes the polyCARBONate to harden. The area being threaded turns black. I've tried tapping less depth at a time, no good. I don't know the chemical process occurring, I just know I can't put threads in it.

hmm threaded inserts sounds promising.

I love the idea of see through bulks.

A steel ring housing could be used for where the bearing would sit to offer a little more strength, if it is even necessary...
