Bonding NEO Magnets

[arlis_1957@yahoo.com]

Doing Grills for current build and I think I may have recessed them a little to much. Just now, I placed a second magnet on the grill side and they really stuck well. So, now I want to bond a second magnet to all twelve on the grill side.
What thin coating will bond these best? Perhaps I need to capture them with epoxy but I would rather do it neatly.
Any suggestions?

Thin CA would certainly bond them, but I'm not sure if the bond would be as permanent as epoxy.

Arlis, how do you make your grills? I do the traditional staple the fabric on the back but I find it very unattractive from the side/back angle or when you take it off. Are you doing something different? Hope this isn't seen as a complete and total threadjack. :o

I've used thermal epoxy for electronics. Obviously don't need to be thermal, but that's what I had around. That was 10 years ago and the neo magnets are still on there. And this item has dropped from 5+ft multiple times onto hard floors.

I guess my biggest concern is that the surface is so shiny.

CA's usually bond better to slick, smooth surfaces than will epoxy since epoxy has poor peel strength. But I've had occasional good results with epoxy on magnets.

I always epoxy my magnets. Also I arrange them so they line up with the heads of appropriate driver mounting screws/bolts so I don't have to also imbed any in the baffle. I epoxy the magnets into recesses on the back of the grille board.

i have used epoxy, ca, and silicone on magnetic knife racks, and havent had anyone loose a magnet yet. CA was the easiest to work with.

Not Arlis, but here's my approach:

Cut a 1/8" dado 1/4" in from the edge of the frame. This can be done on a table saw for a rectangular frame. The grill cloth is held in with 1/8" plastic screen spline.

Re: Bonding NEO Magnets

I am aware of your method but mine suits me fine.

Thanks Bob,
How deep do you make the groove? I assume you use a router on the circle?

Same as the width.
