I recently purchased a T-7 and the bushing in the knife jigs brass bushing has never stayed in place. Is this a warranty issue with Tormek proper or the retailer?
That depends on your dealer.
If it is Sharp Tools USA, contact me by e-mail: jeff at sharp tools usa dot com (no spaces -- you get the idea).
If it is anyone else in the USA, contact Affinity Tools at 1-800-586-7635. Outside the USA, I would suggest you start with your dealer.
Thanks Jeff.
