Hi,
I think that it is important to stick to tried and true ideas and not try to invent the slickest, new, linear bearings. I say this out of experience because I tried to design a formica, UHMW, dovetail slide and ran into problems of uneveness and sticktion. They probably weren't insurmountable but I would have had to rebuild and I was getting tired of messing with it. So I am now going with something that has been done before. Just so I can get a running machine.
