So to be clear, it's the tank that's 1" thick?

Have you thought or tried using hard drive magnets? You might be able to score them, then break them to the size you need.

I've got 1/2 doz of them holding tools onto my tool box. Stick them on the inside and BAM! any steel tools stick to the outside of my tool box. Four of them in one spot holds a small steel tool box in place.

Cheers,
Terry

Default Rare Earth Magnets

I got some from WWW.KJMagnetics.com in the US. If you go to their web page under the coated sub head they have a number of sizes and shapes, and also show you the holding capacity for each one. I use the white plastic coated ones, to hold my frag racks and to replace the suction cups on various pumps, ATO,s etc. Using them back to back there is more than enough power.

Not that expensive.

I got 20 x 3/8 rare earth for $11 at lee valley. And that's ALOT of rare earth magnets.

A couple bigger would probably be less than $15-20.... For sure.

I wonder... does anyone care enough to read signatures if you make them really small? I would not. I would probably moan and complain, read three words and swear once or twice. But since you made it this far, please rate my builds.

Hi Guys,

sorry to hijack, but do you guys think this will work for 10mm glass?
also do you need to coat the magnets?

I was just about to suggest Princess Auto.

I think those 8mm ones might be a bit small.... We've got a whole bunch of those ones on our fridge at home. Wish I was there and I would test them out....

These ones on the other hand, I struggle to get off the fridge... I bet these would work. Maybe even too strong lol. I made the mistake of using one to stick a couple receipts on the fridge and it was so stuck to the fridge it let me remove the paper around the magnet... but I couldn't get the magnet off.
Otherwise it's princess auto... just return them!
