What kind of holding force do mag chucks have? As much as something
like the magnets in the magna bend?

I can easily lift a strip of 1/16" steel off my Brown & Sharpe mag
chuck.

Bob,

I assume that you are asking this because you are thinking about a DIY
Magna bend. One possible source would be your local locksmith or gate
company. Magnetic locks are sometimes taken off due to a failure of
the monitoring switch, but the mag is still good. those would be
about the right size for a such a project.

DOH!

I do access control work (among other things), and have installed more than
a couple mag locks. I have a couple on the shelf in the shop. I think I
have a couple 1200 pounders even. I know I have some 600 pounders.

I wonder if Securitron will sell me just mags instead of full kits.

Now, that's something I should have thought of... and a lot cheaper than
magnetic chucks to play with.

Not really that much. They are designed to hold work being
surface ground -- and even then, they are often dependent on toe plates
which stick up at the end just enough to keep the grinding forces from
sliding the workpiece off the end of the chuck.

If you are thinking of using it as a milling vise -- forget it.
Not nearly enough strength.

Even the electro-magnetic chucks are not that strong, because
they are made to run for the duration of a long surface grinding
operation, while the magna bend is designed to run only long enough to
bend a sheet of metal -- then shut off while you place the next piece.

Good Luck,
DoN.

I know that I have sent one back to them with a dead monitor switch.
I am sure they will sell you anything you want, but they will be a lot
cheaper if you can find a take-off. I suspect that you have enough on
the shelf already however, I think the attraction is stronger if the
plate is thicker, but I could be wrong on that point.

Good luck

Ive got some mag locks kicking around from when I ran an alarm/security
company. When I find them, Ill send them to you.

NOS. Ive not seen them in a few years. They are out in The Stacks O
Stuff somewhere.
