Just a quick update. I trilled the back where the weapons go tonight and there was one close call where I almost ruined it, but otherwise It's turned out great. I went with the 5mmx3mm n52 magnets and they were just a tad too large so the hole went outside the area I needed just a tiny amount, but otherwise they are fairly snug for a first time drill.
With the weapon slotted into place you can't see where the mistakes where I had to go outside the slot. The magnets are so strong so far I'm just going with one each per shoulder for the pulse ordinance array, but can always add more if that's not enough.
Still waiting on the magnets for the waist. Otherwise I am ready to drill as much of it as possible now.
