I have a buck ajust tru 3 jaw Chuck that I need to trade sell or get working on my clausing. I had a backplate for it that fit my old southbend but it went with the trade on my newer clauaing with L00 spindle. Here's my situation. The plant I worked at closed and I'm clearing out and repurposing everything I can because little income. I can't afford to buy a custom L00 backplate from buck and I don't know what to do. If I could get a used or almost scrap L00 backplate with enough material left to turn a boss that will fit this Chuck then I'd be in business. The boss I'd need to turn would be 4.750 diameter and right at an inch depth. If there are no options I'd like to trade it for a milling attachment or handgun of some sort. Thanks for any help. I know it was a long post
