OT: JB Weld magnetic ?

[ddean]

Post extracted from rec.woodworking:

":I had a few of those little (10mm) rare earth magnets around, and needed
some refrigerator note holder-uppers. So I decided to glue a few chips of
granite to the magnets.

One attempt w/ Duco Cement didn't cut it. So I decided to try the "J-B
Weld".

I mixed it up according to instructions, put a dab on the rock chips, and
went to press the magnets into the glue.

As the magent approached, the dab of glue actually lifted off the rock chip
(like a sunspot) and glommed onto the magnet. I pushed the magnet onto the
chip and waited for the stuff to dry. Before it dried, though, the magnet
sucked the glue out from between the rock chip and the magnet, so that the
glue coated the magnet's surface. I'm not sure there's enough left to hold
the magnet to the rock chip.

I guess there's some iron in J-B Weld. And those little magnets are pretty
strong.

This is one of the things I love about the Cantina... where else can you learn stuff like this, and about using an electric toothbrush for polishing knives?
As always, thanks for sharing!

This cantina really is something isn't it? Really amazing.

I believe that you would be correct. I haven't used the stuff in awhile but IIRC, ... Still, that must have been pretty funny looking
