I need some 50mm diameter engineering grade plastic rod - which I could

Came across: Performance Plastics
contacted them.. as I only wanted 100mm long he was happy to cut a 120mm

Very helpful - wide range of stock, might be of use.

I always start with eBay for things like this. Never had a bad
experience with this sort of supplier.
