I have removed mt3 by putting a bolt in the chuck and then putting
something forked on the bolt above the head and using that to bang on.
Best thing I've found is a "Wonder Bar" and then put a block under the
other end to make it level. If the bolt slides out of the chuck jaws
you may have to

I once had to deal with a chuck that someone had glued the arbor in with
red locktite. (And we didn't know that it was locktited.) First tried to use
the wedges, no luck. Eventually we wrote off the arbor and cross-drilled
it so we could put a dowel pin in there and have something more robust

I thought the recommended method of removing a Jacobs chuck was to use
them to machine with an end mill.

Smart move.
My ER collet chucks reside on my mills, and almost never get removed.

spindles)
I do have some smaller drill chucks (expensive, good) that I have on

Web research shows that Llambrich used to be a manufacturer for Jacobs
before all Jacobs production went to China.
So, any Jacobs chuck marked "Made in Spain"

I believe Grizzly owns the South Bend brand name now. They were making
lathes under the name but I think they recently discontinued the line.

Greetings;
Everytime I go to drill a hole, using this POS chuck grizzly puts in the
G0704 kit, its a huge fight getting the wobbly bit to finally grab in
and start cutting somewhere near the center of what the DRO says it is.
When I say somewhere, often 30 thou off the spot.
