I am going to be cutting some clamps for my machine and was thinking about using UHMW sheets for them. Is that a good choice for clamps or is it too slippery? Is there a better choice of plastic? My wasteboard is the Myers style with the holes and T-nuts. I’ve used cam clamps and for the most part they work well, but I have had them loosen up and ruin a piece so I want something a little more secure.
