I use it for brush caps now on DC and universal motors.

Used to use tufnol but it doesn't thread well, Corian does, and also found I can knurl it using a straight cut knurl as opposed to crush knurl [ that definitely doesn't work.

My nephew has a kitchen and bathroom business and he buys it in as 12mm sheets which seems the most popular.

If they need thicker there is a special glue for it so he glues me two 12mm wide strips so I get a 24mm square stick and that does most of what i need.

I do a lot of pen turning with polyester, acrylics and corian. I have found that a standard carbide insert works well, about 900 rpm with slow feed at 0.25mm doc gives an easily polished finish. Be prepared for the material to flex MUCH more than metal when turning. It's all too easy to get a doric column shape when trying to turn a cylinder – when pen turning I try to use the largest steel mandrel I can get inside the pen. The stuff flexes at least 10x further than metals would at the same diameter.

Polish with micromesh, preferably wet with cutting fluid. If you use a slow feed for the final cut, should be able to start polishing with 1800 grade (else start with 1200 grade), and work your way up to 12000 grade for a high gloss polish.

Regards,

Richard.

John , I will be going on the Saturday if that's any good?

We could do a trade off. I have Ali and stainless in abundance?
