I apologize if this has been handled in past forum discussions, but it's been awhile since I've logged on and I don't see a way to search the historical posts. so with that apology, here's my question with which I need help from you 3520b owners. Our club has recently acquired two 3520b lathes and I'm looking for a way to hold in the spindle lock without having a third hand. I have a Powermatic 4224 in my shop and the spindle lock on it has a nut that screws in to hold the spindle lock in position allowing both hands to be free. I've heard some people have solved this problem on the 3520b, but before I go drilling holes, or other modifications I thought I'd seek help from those of you who have already solved this issue.
