I needed some 10mm hard plastic to make joining plates for my new machine. I shopped around and found this company in Dorset, which just happens to be down the road from me and got myself a 500mm x 500mm piece of Acetal (Delrin) for a good price. Plastic Sales Ltd | Plastic Engineering for the Trade Mark, the guy who owns it, has built his own rather big CNC machine for cutting the plastics he sells. So he knows what we are up to, is very knowledgeable with regard to his products and will help wherever he can in supplying the right sort of plastics for the jobs we have to do. I will be putting his details into the Resources area, so anyone in the UK can find a reliable supplier of many types of plastics for CNCing. P.S. I'm sure I'm going to find a use for that plastic threaded bar he sells. He used it to hold his bed down, and of course it doesn't matter if your cutter hits it!!!
