I've got several US made Jacobs ball bearing 18N chucks 1/8 to 3/4 capacity. I've started having problems with twist drills slipping. So I know the jaws are starting to show their age. I've looked around for some new old stock US made rebuild kits without any luck. The rebuild kits from all the big dealers are Chinese.
Anybody know where I can get a US made rebuild kit?
Anybody ever regrind their jaws on a surface grinder successfully?
