I agree Delrin would be the way to go as far as machining plastic. Less of a headache and will last a long time.

I used to work with that junk a lot. I don't know exactly what you are doing with it, but let me tell you that it's very gummy to machine. Never really found a good epoxy to use with it. If your turning it on a lathe you want to use nothing but razor sharp high speed tools, and a slower speed than regular plastics. Delrin is much better to work with if you can find it. It's harder and seems to hold size better. The other stuff actually grows when it gets hot! Dosn't even sand worth a hoot ether. So good luck!

Never trust anyone who refuses to drink domestic beer, laugh at the Three Stooges, or crank Back In Black.

Forgive my ignorance, but what exactly is UHMW?

Hi.

 For the past 10 years or so, I've been cutting and shaping UHMW to sell as assortments on Lee Valley and Woodcraft sites.

 

So I've done a LOT of shaping of UHMW.

 

I've also seen occasional posts from people that have no idea what to do with this very handy material - how to drill, cut, rout and generally shape it effectively and safely.

 

So I've created a help section about it.

 

It's at : www.groups.google.com/group/uhmwtips
