Where to buy magnets for diy frag racks?

[jeremy]

Does anyone know a place to order magnets like the acrylic encased ones so I can make some frag racks?

Best place I've found so far and have ordered multiple times now (was referred to me by Marty mfinn)

lowes. make sure they are ceramic

So the ceramic ones will not rust and or leech in the salt water right?

So did you buy the ceramic ones or did you coat them with epoxy or something?

Good question???

I would buy them from magnet4sale.com and magnet4less.com when I was making frag racks for myself and friends.
I bought the 1" x 3/8" neodymium magnets, but would have to use a polyester casting resin to protect them and attach it all to the eggcrate material.
I also bought 1" x 1/4" black epoxy coated neodymium magnets for the outside magnets.
While they were epoxy coated, and they were used on the outside of the tank, they did tend to rust/corrode after a year or so.
The inside ones never had problem as long as the polyester resin was intack.

I did run across some rubber coated neodymium magnets a few years back that held up for years without any rust, but I can't remember where I got them.

For magnets that are saltwater safe, ceramic magnets are best, but they just don't have the holding power through much more than 1/4" glass/acrylic.

I mostly buy the epoxy coated and spray another coat or three over them them with Black Appliance Epoxy. Or I encase them completely within acrylic. Like on this Probe Holder project below

Great. Thanks everyone.

Hey Todd did you use 3/4 inch acrylic that you drilled to encase them?

Nice work Todd

Actually since I am such a DIY pack rat I salvaged the 1-1/4" acrylic grab bar when I demo'd our shower enclosure during bath remodel....lol
That's a 5/8" mortising bit I'm using for the neo magnet and for those pieces I just flipped over once drilled out and glued in the magnet then glued onto bracket piece sealing in the magnet with Weld-On 16. The other attaching magnetic pieces since being wet enclosed by capping off with a piece 1/8" acrylic (blue)

Thanks Marty

I'll post up a new thread here in a bit showing the whole project.

Cheers, Todd
