The joys of magnetizing

   One of my many projects is to magnetize my Centurions. Sure,  I could just put them together with grav-guns and call it good, but would it be? There are just so many options and each one has is merits. As the saying goes, right tool for the right job.
Magnetizing the weapon load outs is going to give me many more options when it comes to fielding these models.
   The arms come in three sets. Each set is paired by the details that adorn them. With three sets of legs, torsos and arms, that comes to 27 different combinations you can build. Add in the four different weapon potions (not counting flamer vs. Melta on the siege drills,) that jumps you up to 108 different combinations. Yet,  by filing down the details on one, or both arms, giving you the option of using different arms and not mixing iconography, you then end up with a whopping 324 different builds you can use to make each centurion! If I decide to, and I'm able to, magnetizing the secondary weapons of assault launchers, hurricane bolters and missile launchers will give me 972 combinations!
   Although it is possible to magnetize everything and get all the combinations, I don't find it to be practical. The 4 main reasons being; time to do all the work, cost and supply of magnets, stability will be desired between waist and torso and the fact that each arm has it's own specific wiring you can use with it. So therefore I will be gluing the legs,  torsos and arms together and only Magnetizing the weapon mounts themselves. After everything is assembled this will still give me all the options for arming my Centurions. It still comes out to 4 different weapons choices for each one. 12 combinations if I can properly do the secondary weapons.
   The magnets sizes I have chosen to use for this project are 1/8x1/32 and 1/8x1/16. The taller piece is going to be used in the arm itself for a deeper, stronger bond with the thinner magnet attached to the weapon itself. When working with magnets,  the more you can use,  the stronger the bond will be. I would like to be able to use the larger size in both the arm and the weapon,  but there isn't as much thickness to work with on the weapon itself. I would hate to drill through and damage all the detail.
   At the time of posting this, I have only just started and have one arm complete. After some cutting and filing on the inside of the weapon, I was able to satisfactorily get a magnet inset and keep the weapon mostly flush when attached. The bond is strong and the weapon doesn't move around too freely and stays on when handled. The next arm I do, I am going to try something a little different to how the magnets will attach. Rather than drilling into the weapon and placing the magnet,  I'm going to drill deeper into the arm so both magnets sit flush into the arm itself when the weapon is attached. If this works, it will limit the admit of trimming I will have to do to attach the magnet to the weapon and hopefully cutting down on my work time. I'm thinking it will give me a little added stability to the join by creating a plug type attachment. The arms seem thick enough to handle a hole slightly deeper than 3/32 to accommodate this.
   In the next few days,  I will edit this post with pictures and details showing how it all is working out.
