Magnetizing predator sponsons

This is how I have magnetized my Rhino-chassis. I have four Rhinos, which can go as Rhinos, Razorbacks or Predators.
What you need:

• 3 mm magnets
• 3 mm drill
• Some sprue
• Scalpel (optional)
• Super glue
• Marker pen (optional)

First, I drill a hole in the sponson and glue a magnet in there. 

Then I cut a piece of sprue to fit on the chassis. I make sure that I cut it down a bit so the sponson can fit. After this, drill a hole in the middle of the sprue (I use a scalpel to make a small dent to guide the drill).

Finally, glue another magnet in the sprue. Make sure that you have the polarity in the correct direction. Easiest way to do this is to let the magnet go on to the sponson, mark it with a marker pen and then use the mark to remember which side goes first in to the hole in the sprue.

Baal Predators, ready to mow down some xeno scum!
