Happy fun time dealing a fist full of death that is... and doing it with options makes it just that much better. So here's my latest project - a Landspeeder for my Genesis chapter of Spacemarines. I couldn't decide if I wanted the Heavy Bolter or the Multimelta. So I decided on both and to try my hand at using magnets.
I used 1/16" diameter by 1/32" thick Neodymium magnets. Better known as 'rare earth magnets' even though they're anything but rare. I bought mine from a local PA company K&J Magnets. Just $6.00 landed me 100+ of these things.
It didn't take much to do really. I used my pin vise with a 1/16" bit to drill a small hole and pressed the pin in. Surprisingly it didn't need glue as the magnet was pretty snug despite the magnet and hole having the same diameter. One thing I learned the hard way... be sure the magnet polarities match up before pressing it in.
