One of my staff was using a parallel split mandrel in a #30 handpiece today. As has happened once before, the split mandrel had become slightly out of round, started running a bit wobbly, and then centrifugal force forced it to bend enarly 90 degrees at the shank. No big issue, we all wear safety glasses and are cautious when using split mandrels now that we know that’s a possibility.
The issue is that the force of the mandrel bending appears to have damaged the handpiece. The chuck jaws are now out of alignment and I don’t know the best way forward in fixing this issue. Of course ordering a new one would be ideal, but I’m located a bit far from any shop, so fixing is preferable.
Thanks in advance for any advice!
