I'm slowly collecting the models to build a 2k pt blood angels army, and I was thinking of magnetizing all of their weapons and gear so that I could change it out for different things, like magnetizing the dev squad i'm running at the weapon arms so i could switch them up, like magnetize some lascannons, mls, and plasma cannons and such so that i could switch out their heavy weaponry. I was wondering if there are any guides on doing this, and what kind of tools I would need. I'm thinking of using rare earth magnets because the size and strength seems suitable. However, I am lost on how i would make the holes for the magnets and if anyone has ever done it before or has a guide on how to do it, it would be greatly appreciated. thanks.
