I want to use my woodworking power tools and make flat curved parts up to approx. 10 inches in size/diameter and 7/8 thick from very strong plastics. These should never break, are held/handled as standalone items by people and have a rather smooth but NOT supersmooth/supershiny appearance to make handling comfortable but not slippery. I need something low cost and stronger than Finnish multiply. I am thinking of nylon (very strong but seems really too expensive) or UHMW-Polyethylene or any low cost plastic I can machine myself, or as a last resort request a contractor to do it with CNC machining. All the parts will have 1/4, 5/16, 3/8, 7/16 or 1/2in rounded edges (roundover). Any recommendations? Thanks.
