on my 60 yr old er 4 digit serial,, ive noticed my quill is a little loose,, i was thinking of drillingm three holes and using brass bolts with stop nuts to hold the quill steady,, any suggestions,,,indianabob

How is it lose? Is the play from side to side or in and out? And I'm not sure I understand the fix either. Wouldn't that keep the quill from extending?

Are the bearings original? Perhaps the fix would be as simple as replacing them? Before you start drilling holes in it, I'd want to identify the actual cause of the problem.

Your proposal would be an extreme re-engineer for what could be a problem with a more simple solution. Not saying your idea may not have merit but understanding the true root cause is critical for the 'correct' fix. Try to elaborate more and the flood gates of suggestions will open.

Make sure all 'setscrews' are loosened/removed prior to using bearing puller(yes you will need a bearing puller).
