I have to ask, what's the issue with drilling holes in the base? You can get rare earth magnets in diameters that are easily compatible with the range of drill bits that will work in a pin vise. The process can be tedious when working in large batches, but it's by no means difficult. I've yet to ruin a single model by adding magnets.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9494832.page http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9494832.page GMT Question about magnetizing bases
Any advice for the number, diameter, and grade of rare earth magnets for an Imperial Knight base? Also, can you recommend a bit for a vise?]]> http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9495511.page http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9495511.page GMT Question about magnetizing bases GW Plastic base.

Those fit nicely into the clearance beneath a GW knight base and are more than strong enough to hold the knight (plastic or resin) securely without being too strong.

See: https://www.supermagnete.de/eng/disc-magnets-neodymium/disc-magnet-diameter-6mm-height-2mm-neodymium-n45-nickel-plated_S-06-02-N

A problem when supergluing rare earth magnets to big bases is the flex of the base. For that reason I drill a hole with the exact diameter of the magnet into a bit of plasicard (sheet plastic from the model store) use plastic cement to stick that to the base and then superglue the magnets into that.

If you are making custom bases from resin, odds are they are at least 3-4mm thick, so a 2mm deep recess should be no problem at all, assuming that you are using a drill with a piece of tape or marker to help you gage the depth correctly.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9495701.page http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9495701.page GMT Question about magnetizing bases

Thanks. I was actually thinking of using dry-processed HDF.

Do you have any experience with magnetic strips/sheets?]]> http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9496124.page http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9496124.page GMT Re:Question about magnetizing bases
I've never used strips or sheets, but I have used sheet steel from the hardware store (HVAC department) and it works like a charm. Attach the steel to whatever you want, put magnets in the base or model, and you're good to go. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9496297.page http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9496297.page GMT Question about magnetizing bases https://www.kjmagnetics.com/proddetail.asp?prod=D42

I am magnetizing Skitarii and Knights. So I am thinking 2 magnets for my Dunecrawlers and Ironstriders (which are walker vehicles) and 3 magnets for my Knight Crusader. Is this too many?

I will drill through the base with a 1/4" bit, glue the magnet to another piece of HDF (or something that will be a part of the base), insert the magnet through the top of the hole, then glue it in place on top of the larger piece of HDF.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9496315.page http://www.dakkadakka.com/dakkaforum/posts/preList/732877/9496315.page GMT Question about magnetizing bases

1/4" x 1x8" should work fine, a bit thicker than what I use, but that should be ok.

I am mostly using magnetic sheets for the smaller plastic models. Only for the 40mm (terminator) bases I use a single 4 mm neo-dym magnet since it's more convenient with the nubs under the base.
The magnetic sheet I use has an adhesive foil stuck to it. I use that foil to combine the thickness of two sheets - since that matches the clearance under th plastic bases. I cut the foil with scissors or ruler and box cutter and scrape away any plastic nubs or raised letters, then I put a dab of super-glue down as insurance against failing self-adhesion and stick the magnet foil under the base.



I hope this helps.
