I’ve got a tub of magnets. They’re random, from God only knows where. I don’t know their sizes, strengths, or what to do if I need more of a particular kind.
So, a couple of years ago, I broke out the calipers, did some planning and (most importantly) took notes. Now, I keep these magnets in a tacklebox, separated and labeled, with appropriately wide drill bits.
All of these are sourced from Amazing Magnets. you can probably get the same sizes from other vendors like K&J Magnetics, but I vastly prefer AM because they list sizes in both metric and, where they list Imperial sizes they use decimals instead of fractions. So: these are the AM item codes.
(Let me take a moment to express the hate I feel for defaulting to fractional Imperial measurements for this shit. Fuck off with this 1/32″ shit.)
If it’s useful, here’s my chart:
|R094-094||2.38mm||2.38mm||Small plastic bases|
|D063A1||3.97mm||0.97mm||Padding for D094A1|
|D032A1||3.97mm||1.59mm||Padding for D094A1|
I also have some magnets that are perfect for the hole in Necromunda bases, but somehow I failed to correctly note them. My notes say “D063A” but that’s not right: those are 3.18mm wide but the magnets I have are 2.9mm wide.
Small, light minis will get R094-094s. Most of my minis get D094A1s, which are just the right depth for GW bases, and I supplement them with D063A1s (which are ~1mm deep) and D032A1s (which are ~1.5mm deep) to help get the needed depth if ~2.4mm isn’t deep enough.
