Adjustment about magnetizing weapons

magnets are expensive so you should use the least of them unless you are a millionaire. since i am a poor italian student, i used only 2 to magnetize the hull heavy flamer of my demolisher. the problem with this method is that the weapon rotates, which is silly.

a really smart idea (which is not mine but Orlando's, thank you bro) is to make a pin to prevent the rotation. so simple...
