17994RE: [multimachine] Magnetic chuck plans posted to files
- Feb 24, 2014Jack -
The October, 1982 issue of Popular Mechanics had n article on building a permanent magnet lathe chuck, though it doesn't have a release lever - the work it just slipped sideways off of the magnets to release it. This isn't as handy as having proper release lever. I think you would also only be able to take very light cuts with very sharp tools using their design since the magnets are only rated for 40 lbs force.
Here's the link:
I recall one with a proper lever release. I'll keep looking.
