Step 1: Cut off the turret peg

Step 2: Drill a hole for the magnet. The hold should be drilled just deep enough so that the drill bit is just starting to drill at it’s specified diameter (just beyond the angled tip)

Step 3: Glue the magnet in the turret

Step 4: Open up the hole in the hull to the same size at the turret magnet if necessary (in this M1 it was not necessary) and then glue the larger hull magnet inside the hull

All Done
