Adam Czepiel

gorilla glue expands when it dries, not a good idea...

most use JB weld others have used 2 part epoxy putty with good results

Harborfreights' cheap 2-part epoxy.

JB Weld is adequate but nothing special. The chief attribute is that it's readily available.

When I took the magnet off, cleaned it, and reassembled the driver, I used a generic equivalent to Loctite 271 red anerobic high-strength thread locker. Available at any auto parts store.

I've always had good luck with JB Weld but the next go around I want to try Red Loctite

I think Red Loctite would be a poor choice to secure the magnets. It only cures in the absence of air. I doubt it would get very hard if applied to the outside edges of the magnet the way it is done with JB-Weld.

I agree. I've found it to be a gooey, tacky mess that hardy will hold it's on weight for very long. Maybe other people have better luck with it.

I've used JB Weld, 10 Minute epoxy, and while they are excellent, I now use Loctite Power Grab Acrylic. It's easy to apply, clean-up with a damp rag, dries clear, and contains no silicone. Also works extremely well for re-sealing cabinet interiors.

Note the photo included with the suggestion for Red Loctite (271, or equivalent)

This product is not used to reinforce the existing bond. It is used to REPLACE the existing bond, after total disassembly of the magnet and pole piece, and cleaning off the previous (failed) adhesive.

I think it was Loctite brand one minute epoxy used it so I wouldn't have to disconnect speakers This stuff dries VERY quickly and prolly ha senough strength to do the job just applied it at the joints at even intervals around the perimeters

For one of my speaker projects where I had to add additional wood bracing inside the speaker cabinet to hold a Solen 14mH inductor, I started with Elmers Carpenter Glue, then when that ran out (I needed more than I anticipated the project would need), I used Gorilla Glue to finish the project. That was a year ago, and everything is holding out very well. I would say 75-80% Elmers Carpenters Glue was used for the project and the remaining was Gorilla Glue.

Had I known about other peoples reservations before starting the project, I would have returned the Gorilla Glue for more Elmers Glue.

Last time I used JB weld steel stick. It's a two part apoxy that looks and feels like a toosie roll. I kneaded it and rolled in around in my hand. Next I rolled it out into a long thin tube like a straw. Then i pressed it into the seems around the circumference.
