Field Ordnance Battery Magnetization Guide
Before you even start clipping sprues or opening your plastic cement, there’s that familiar hobbyist anxiety: you’re already worried about committing. Do you build the gun that looks coolest? The one that’s strongest on the tabletop?
In this guide, we’re going to break down everything you need to know to magnetize your Field Ordnance Battery like a pro. Whether you’re a hobby veteran or just starting to dip your drill bit into the world of customization, this step-by-step walkthrough will help you achieve clean joins, strong holds, and seamless weapon swaps without damaging your model’s aesthetic.
To keep track of magnet polarity, we use a set of Magnicator tools. We may refer to the polarity of the magnets as “red” or “blue,” after which Magnicator is attracted to that magnet’s surface.

Magnets Needed: Field Ordnance Carriage
16pcs 2mm x 2mm
I assembled the carriage that the Field Ordnance Battery normally uses. Beneath the carriage of the field ordinance gun, I drilled a 2mm hole into the axle where there’s already a small hole extending upward. Don't drill all the way through.
Using the red end of the Magnicator, insert 4pcs 2mm x 2mm magnets into each drilled hole. This will ensure the magnet for the swivel mount is extra strong.

Magnets Needed: Bombast Field Gun and Heavy Lascannon
4 pcs 3mm x 0.5mm
Speaking of the swivel mount for the Bombast Field Gun and Heavy Lascannon, I took extra precautions here. Drill a pilot hole into the bottom, which does not go all the way through, then widen the hole to 3mm.

Take your time, carefully scraping away just enough material for a 3mm x 0.5mm magnet to fit, and insert the 3mm x 0.5mm magnet using the Red end of your Magnicator. To swap between the Bombast Field Gun and Heavy Lascannon, push fit the swivels into the holes!
Magnets Needed: Malleus Rocket Battery
2pcs 3mm x 1mm
2pcs 3mm x 2mm
Let's move on to the Malleus Rocket Battery. On the top side of the carriage, in the rectangular hole where the rocket battery would normally be glued, insert a 3mm x 1mm magnet with the Blue end of your Magnicator.

On the bottom of the rocket battery, use the Red end of your Magnicator to glue a 3mm x 2mm magnet. This setup provides a magnetic pull to keep the battery in position.

Magnets Needed: Blast Shields
12pcs 2mm x 1mm
Lastly, let's move on to the blast shields. On the carriage, I snipped off about half of the connecting piece for easier access, taking off the blast shields.
On the front of the weapon carriage, I drilled a 2mm hole on both sides where the blast shields would connect and glued a 2mm x 1mm magnet into it with the red end of the Magnicator.
For each of the blast shields, I applied paint onto the magnets on the carriage and dry fit the blast shields. The paint marks where we need to drill to insert our magnets. Drill into the blast shield with a 2mm drill bit and glue a 2mm x 1mm magnet with the blue end of your Magnicator into the blast shield.

Your army is now ready for every firing solution possible in tournaments, games at home, or for the display shelf.
