Mini magnets for tanks

My sample shipment of mini magnets came through.  I intend to use them in order to have magnetized tank turrets.  They don't fall off and they turn really smoothly.  Put the first pair in, which wasn't easy.  I really have to get a non-magnetic pincet, and a new drill that makes clean 2mm holes, because the one I have now is not in good shape.

Therer definitely is some technique involved in mounting the magnets:  do it the wrong way and before you know it you have magnets covered in superglue flying around.
