Magnetizing Miniature Bases for Secure Transport
Magnetizing bases is a way to secure painted miniatures to a ferromagnetic storage surface, often a steel sheet inside a carrying box. The goal is to prevent figures sliding into each other during ordinary movement, not to promise a box can withstand any impact or orientation. The correct magnet and tray depend on the model’s weight, base geometry, available clearance and the sheet material. Test with an expendable figure or unpainted model before trusting a finished collection.
Check the transport surface first
A magnet needs a compatible magnetic target. A shiny metal surface is not necessarily ferromagnetic: some stainless steels and aluminum will not work as expected. Test the intended sheet with a loose magnet before building the tray. Secure the sheet inside the case using a method compatible with the case material and any adhesive manufacturer’s instructions. Ensure cut sheet edges cannot scratch models or injure hands.
Measure the base’s underside depth. A magnet suspended far above the steel by a thick hollow base may grip poorly even if it feels strong when placed directly on metal. A flush-fitting magnet or steel insert may improve contact, but do not drill through a thin or decorative base just to fit a larger magnet.
Choose magnets by actual model and base
Compare a small plastic infantry model with a tall metal figure. Their loads and leverage differ dramatically. Larger or additional magnets are not automatically safer; very strong magnets may make removal difficult and can pull against fragile glued base details. A simple fit test is more useful than choosing by diameter alone. Use the manufacturer’s dimensional and handling guidance for the chosen magnet.
The Army Painter’s miniature magnet guide emphasizes planning the location, making appropriately sized holes and checking polarity before gluing. For base-to-tray storage, polarity is less important than with interchangeable magnetic weapon arms, but keep orientation consistent if you also use magnet-to-magnet attachments.
Mount the magnets securely
- Check base clearance and mark a location away from fragile edges.
- Use only tooling suitable for that base material; a hand pin vise gives controlled drilling.
- Avoid drilling or modifying the magnets themselves.
- Dry-fit the magnet and confirm it does not rock or protrude unexpectedly.
- Attach with a compatible adhesive and allow full cure as directed.
- Test removal by sliding or lifting gently at the base, never by pulling the painted figure.
Consider placing a protective thin liner between trays and exposed paint where the case design allows it, but remember that any extra distance can reduce magnetic grip.
Test the complete system, not just one component
Use a fully cured test base in the real case. Check gentle side-to-side motion, the fit under the case lid and whether tall models catch against shelves. Try carefully lifting the box and setting it down during normal handling. Do not shake it aggressively or turn it upside down over valuables to prove a point. If a miniature slips, reduce leverage, improve contact or move to individual foam compartments instead.
Do not stack miniatures so weapons touch neighboring bases. Magnetizing prevents sliding only when each model has enough clearance and the tray is structurally sound.
Treat small powerful magnets as a safety item
Neodymium magnets are not toys. K&J Magnetics warns of pinching, shattering, and serious injury from swallowed magnets, especially when multiple magnets attract through intestinal tissue. Keep them away from children and pets, secure loose pieces, and seek emergency medical attention if swallowing is suspected. Do not drill, grind or heat neodymium magnets; dust can be hazardous and flammable. Follow guidance concerning electronics, medical implants and sensitive equipment.
If the box may be used where people cannot control orientation or vibration, add a secondary restraint. A clear label and sensible carrying method are part of the design. Test and document your configuration before adding all your painted miniatures.
