I recently bought the 5" vicmarc chuck. I noticed after a few uses that the jaws were binding on me. thought it was due to some wood particles jambed under the channel. I took the jaws off to clean and found that this was not the case. On the #4 jaw it appers that a particle of metal came lose and got stuck in the channel. this began to cut a grove into the channel and bound up the chuck. did i do something wrong? i only turn wood. and have a clean shop. is this a manufacture flaw? should i attempt to send it back??
