Magnetic Frag Rocks for 1" walls

ca1ore · 03/14/2018, 01:58 PM

None of my frag rocks work on walls thicker than 1/2". Anyone know of any that will work on 1" thick walls?

I have some I made with mp40 magnets

If Ecotech would sell you some mp60 magnets you could probably make some cool ones that would work on 1"

Just pick up a stronger neodymium magnet for the outside..

This seems like the best idea and just cover them in some way, if not already, for wear/tear and splash. Can generate the extra force from just the outside.

Finding ones that can go inside is the only tricky part IME, I have found some cool retailers for smaller ones encased in clear acrylic (I want to SEE if those things rust!) that I use for general purpose stuff, but not for 1".

I already tried that. Not enough on the inside to grab onto and they just torque off the walls. Used N52 with 30 lbs. of pull .... I guess I'll try using the plastic coated ones on the inside to see if that does the trick.

Funny you should say that, was toying with trying to make one with the WAV magnet mount. It does work on 1" walls.

That is a weak rating for what you want to do. You can find N52 or N42 magnets rated for much higher than that. I frequently use N42 magnets rated at 90lbs. You can usually find them for around $30 plus shipping.

Tunze magnets work. But are costly

Yes, clearly

I am gong to try a spare set of WAV magnets that I have sitting around. If that doesn't work I may abandon the effort.
