I have 2 peices of teflon 2x2" by 3" tall teflon . They have a 3/8 inch hole through the middle. I got them from a TV engineer in the early 80's. Been moving them around for years. It seems like fate. It compression strength of 3500 psi and tensil of 6000 psi good to -100 degrees to +400 F. How would cut it? I do have a diamond band saw but I haven't tried it yet. What Ya'll think?
