Grinder Attachment for Trueing up the 3 Jaw chuck

I seen this before and I did not know it was vtsteam. How did grinding your chuck work out? I forgot where I seen it and that is the reason I getting back to you now. I just wonder if it worked or not.

vtsteam:
It did work, Nelson.

I saw it years ago on some early site dedicated to the Asian style mini-lathe's. I don't think the original writer used JBWeld putty to attach an adapter block, maybe he used fastenings -- can't remember. But anyway, yes the end result was the same, and yes he used the high speed of the lathe to keep the jaws out against the chuck's internal scroll.

I like that!

I have 4 chucks all of which are decent quality for my boxford. Yet 3 of them have worn jaws and so I can only use one of them!! I've considered something similar as I can't afford a tool post grinder right now. I'd just be concerned how rigid the Dremel sits on the tool post and the runout of the dremel, but then if it worked for you...!

I might be following you.  :beer:

The run out on the Dremel cancels out if you dress your stone first, I agree rigidity is potentially an issue - it will tend to bounce and not give you a good surface finish. Microscopic feeds I reckon!

Chris, I thought you made a very whizzy milling spindle with a brushless motor. Wouldn't that be more rigid than a Dremel?
