[MachineShop] New Safety Check for South Bend Lathe

[John P Anthes]

Wow! Sure am glad you learned of this situation Denis.
Honestly, I cannot imagine how this happened?

Untrained users?

I’ve spoken a few time of a 4-jaw chuck. But we never located one? I do rather recall having one at sometime?
And I don’t recall a collet chuck available that would substitute for the 3-jaw chuck?

I just don’t get it. But and pleased that you discovered the concern.
THANK YOU!

It turned out that the camlock position screws were in the open position, except maybe for one which was halfway. This could have caused the chuck to come off during operation. This might explain the parallelism issue some users ran in to during training.
