I thought most 'non-lead' ones where some kind of pewter, but I maybe wrong.No, you'd pin some metal in one end and a minimagnet in the other.
Seems to be popular for attaching X-Wing ships to their stands to get adjustable ships.
Edit: fan solution.
Edit edit: heh, is the usual metal miniature not-lead-anymore stuff even magnetic?
Not at all. Metal miniatures are usually made from pewter, which is non-ferrous. In order to use magnetization for parts, you need to use magnets in addition to the parts (really small rare earth magnets aren't hard to get.) The big issue is that this often takes a bit of conversion work. An example in ABS plastic is that I was considering doing this with my Robotech Phalanx destroids. It would have entailed six magnets per miniature, one for each arm in both variants and two for the body of each destroid, as well as having to drill out each part enough to put the magnets in.You'd have to have like metal miniatures for that?
With neodymium magnets, they stay well attached - those things are amazingly strong for their size! They're dangerous to keep around small children and pets as if swallowed they can do quite a bit of harm to the intestinal tract - so if you get some keep the ones not used locked away.How well do the parts magnetize? Do they get knocked off easily if you move the miniature about? Do the magnets eventually lose their magnetism?
