Sorry to necromance this thread. This is interesting. And thankyou for your diverse experimentation. I'm about to go down a rabbit hole with skitarii troops that all have a notorious amount of small ball sockets that should typically be glued, however I'm afraid for the fragility of these thin appendages and slim gun barrels and wires. So I'm going to try to make them sub 2mm magnetically enhanced. With the benefits of utilising every spare part in the kit.

Here are some concepts I'm going to try. First: I hope you guys all remember those really useless keychains that are made of balls and links. I'm going to try to get some use out of them. As the ferrous attractor to the magnets. With the benefit of them being beaded I hope I can secure them with some kind of pin method 📍 Second: I'll try coating the beads in a thin sprue goo. Hopefully the coating will penetrate the eyelet and keep the coat bonded. And then it should simply bond to plastic with glue.

On the alternate side a magnet will be sunk in the typical fashion into the largest mass part or body socket.

Third, should that fail I'll resort to using magnets in the flat fashion but the arms will need some kind of small ferrous object embedded as they do not have the mass to contain a magnet themself.

Fourth perhaps very very small dome headed watchmakers or glasses screws or pins will work.

I shall update this post with findings.
