We have a Flow Mach 3 4020b and we seem to lose at least one proximity sensor on the head each month. Not the same one each time. The machine runs two shifts each day, running pretty constant for about 15 hours daily and about 10 hours Saturday. Wondering if anyone else has the same issue.

I am looking for a way to POSSIBLY cut 3mm to 16mm "cardboard like" material, while absorbing minimal moisture. The parts are filters used in high voltage electric generators, so the less water absorbed the better. I believe the process would be similar to cutting jigsaw puzzle pieces. I...

I had an interesting request from a contractor to try and cut a hole in a glass bouy. I havent seen the bouy yet (he is going to bring it by friday). I know at the very least it will cut a hole completely through it.......has anyone tried to cut a hole in a glass ball or something similar? Will it blow up?
