Re: Chuck unscrewing from shaft

Bill Boehme
Sounds like a clear case of sanding in reverse with too much sanding pressure. Vicmarc uses a different retention system than everybody else. They expect you to buy a Vicmarc lathe as an accessory to your Vicmarc chucks. If that sounds a little too extreme then you could consider drilling and tapping holes for a couple setscrews. The ideal location is in the groove that Vicmarc uses for the retaining clip. Another option is to tighten the chuck to the spindle with a snap of the wrist to firmly seat it against the shoulder ... but not so tight that it gets permanently stuck. :D
