Magnetizing Land Raider Sponson Weapons

I finally picked up another Land Raider and decided to go the magnetizing route instead of the pin and tube method I used for my Land Raider Redeemer. While the example Land Raider is the Chaos version, I used the same technique for my Baal Predator, so that I can swap out the sponson weapons.
The operation is very simply, mostly because the holes already exist and just need to be opened up a bit. I'm going to magnetize not only the lascannon connections, but also the top of the sponson brackets, to accomodate Havok launchers, hunter-killer missiles, the targeter, or anything else you want to add.
What Will You Need?
For this project, you'll need the following (SKU numbers refer to the K&J Magnetics part number):
6 X 1/8" x 1/32" disc magnets (D201)
8 X 1/16" x 1/32" disc magnets (D101-N50)
Pin vise with a 1/16" and a 1/8" drill bit
Scribe or sharp pin
Superglue
Toothpick
Flat file
Step-by-Step
Before you assemble the sponson assembly, use your 1/8" drill bit to open up the holes on both sides of the top bracket and the upper part of the bottom bracket.
Once the hole is big enough, test fit one of the 1/8" x 1/32" disc magnets to make sure it will be flush with the surface of the sponson bracket. If it isn't, simply push it out with your toothpick and keep drilling.
Once all 6 holes are good, glue them in place with a little bit of super glue. I would put a little bit of glue into the hole, push the magnet in, and then use the flat part of pen cap to tamp it into place. The flat surface helps make sure the magnet is flush and even.
NOTE OF CAUTION, be very careful to watch your polarities. If you get them mixed up, it will be very hard to undo after your magnets are glued in.
You can now assemble your sponsons. Glue the top and bottom brackets to the base.
Now it's time to prepare the posts on which your lascannons will be attached. Measure the post against the assembled sponson and carefully clip off the parts that would have been inserted into the holes. Use your flat file to adjust the fit. You want a tight enough fit where it will almost stay in place by itself, but not so snug that you have to force it in.
When you are happy with the fit, use your scribe to mark the center of the post and then use your 1/16" drill bit to open up a hole for your small magnets. Use a toothpick or your scribe to check the hole depth. If you use your magnets, you might not be able to get them back out. Do this on both sides of the post.
Once you are happy with the fit, you can glue in your magnet. I usually use 2 of the small 1/16" x 1/32" disc magnets on each side. Again, use the table surface or a pen cap to tamp the magnets into place.
To magnetize options that will go on top of the sponson, simply drill a 1/16" hole in the base of whatever you want to add, drop in a pair of 1/16" x 1/32" disc magnets and you're done.
Here is an annotate illustration that shows you what magnets I used and where I put them.
