spent the last hour messing with this stuff. got it broken in now and added a bit of teflon lube spray to it. I am really amazed, so smooth running. My first attempt at making brass bushings.
I made some delrin and UMWHDPE bushings in the past along with some PLA+ ones but these take the cake.
Im seeing a 6090 mill in my future with a 1.5kw spindle made from some lasered steel parts using this stuff…
