That's putting it lightly.
I don't care how you hold it down, UHMW is incapable of being machined in perfectly parallel or square sides. That stuff defies all the laws of physics and geometry both. And the bigger the piece, the worse your results, speaking in a precision tolerance sense.
(Sarcasm) I swear you'd be just as successful
ing it into the desired shape as cutting it
Can you tell I had to mill a bunch of it just last week? I can't remember being that frustrated except the last time I turned a bunch of Inconel for a month
