So, I was impatient and decided to purchase some magnets at a local hobby store, the Rare-Earth Neodynium 1/4" cube magnets, in a pack of 20 to magnetize my newly purchased Wraithknight. I already have some smaller 1/16" x 1/16" cyllinder magnets for smaller weapons, but I needed something stronger for the arm attachments and also to make the torso rotate just for fun. In retrospect, I should have waited for a mail order of 1/4" disc or cyllinder ... but alas, here I am.

I already mounted the magnets attached to the torso, and am soon to do the arms. But I have to say that using square magnets is a PAIN. I am very used to using round magnets that are quite easily mounted by carefully drilling out a whole with succeedingly larger Drill bits. However, With the square magnets to fit tightly, I have to carefully drill, then even more painstakingly file out the corners. It took me 2 hours for 4 mountings. Any ideas for making the arm mountings easier? they have a whole for a socked that is no longer there, I just have to carve back into concave plastic about a 16" of an inch, in a square shape, without destroying the arm.

The other option is to cut the magnet, but I'm pretty sure I don't have access to a tool that can do that. I wouldn't even know how ...

Ideas?

Drill bigger, so 4 corners fit in hole. Apply GS. Call it a job well done.

Call it a lesson learned, go buy the 1/4" disc magnets, and work on what you can while waiting for them to arrive (3-4 days?).
Hold onto the square ones because they do come in handy for other projects; magnetizing Land Raider sponsons and even flyers onto their poles.

+1 to this.

I used 3mm round ones in my NDK.

Right fist, both weapons, and on top (so I could magnetise the personal teleport array and make him look like a big jump marine). In any case, I also used GS to seat the magnets, because unless you mill out the holes after you drill, you are left with a concave hole (that a flat magnet is just going to want to rotate in). The GS helps to seat it while the glue dries.

I actually have a few small end-mills that I turn by hand to make flat bottomed holes.
