I had trouble today with our Kerr 4X6 centrifugal casting machine.
After about 20 flasks it wouldn’t wind up anymore. I removed the top
to check to see if the spring snapped but it was fine. It all seemed
intact. I made sure the small ball bearing was in place and replaced
the top. It worked one more time then would not wind a second time.
This time being a little frustrated and thinking the ball bearing was
stuck I took a leather mallet and mildly rapped on the top cover in a
few places. It worked again for a few times then stopped. Now it
seemed to start working again after each time I rapped on the top
cover. So could it be the centrifugal mechanism was overheating and
the bearing getting stuck, I am going to try ands use Krytox grease,
a high temp lubricant, and hopefully it will fix the intermittent
My question is has anyone else had this experience and if so how did
you fix it?
