The Comprehensive Guide To Magnetizing D&D Miniatures For Secure Transport And Modularity

Magnetizing your Dungeons & Dragons miniatures involves installing neodymium magnets into the base of each model to ensure they lock securely onto steel-sheet lined storage cases, preventing damage during transport. Achieving a professional finish requires precise drilling, correct polarity orientation, and the use of high-strength cyanoacrylate adhesive to create a permanent, flush-fit bond.

Essential Preparation and Equipment Checklist

Before beginning the magnetization process, you must assemble the correct tools to avoid damaging the resin, plastic, or metal of your miniatures. Inconsistent hole sizing or improper glue selection are the leading causes of base failure. The primary goal is to seat the magnet perfectly flush with the bottom surface of the base to maintain stability on both storage trays and game tables.

• Essential Hardware: Neodymium magnets (typically 3mm x 2mm or 5mm x 2mm depending on base size), standard metal hobby drill (pin vise), and high-quality cyanoacrylate (super glue).
• Safety Gear: Protective eyewear, as small neodymium magnets can shatter if handled aggressively, and a well-ventilated workspace for adhesive application.
• Measurement Tools: Calipers are recommended for ensuring the magnet diameter matches your drill bit size.
• Surface Preparation: Fine-grit sandpaper or a metal file for roughening the plastic base to increase adhesive surface area.
• Duration Benchmarks: Budget approximately five to ten minutes per miniature for drilling, cleaning, and curing.

Procedural Workflow for Precision Magnetization

Step 1: Selecting and Verifying Magnet Specifications

Determine the weight of your miniature to choose the correct magnet size. For standard 25mm and 28mm plastic bases, a 3mm diameter magnet is sufficient. Larger models, such as ogres or monsters on 40mm to 50mm bases, require 5mm magnets or multiple 3mm magnets to account for the increased center of gravity.

Step 2: Marking the Center Point

Using a permanent marker or a scribe, identify the center of the underside of the base. If the base has structural supports or plastic webbing on the interior, you may need to choose a position slightly off-center to avoid the structural plastic. Precision here is critical; a poorly placed magnet will cause the miniature to tilt or wobble when placed on your storage tray.

Step 3: Drilling the Anchor Point

Insert a drill bit equal to the diameter of your magnet into your pin vise. Slowly rotate the drill to create a recessed hole in the base. It is vital to stop frequently to test the depth; the goal is for the magnet to sit perfectly flush with the bottom rim of the base. Do not drill through to the topside of the base.

Warning: Never use a high-speed power drill on hobby miniatures, as the friction will melt plastic and potentially shatter resin, creating jagged, uneven edges that prevent a flush fit.

Step 4: Maintaining Correct Polarity

This is the most critical step to avoid frustration. Place all your magnets on a steel sheet or a "master" magnet to ensure they are all oriented with the same pole facing down. Use a permanent marker to put a dot on the "top" side of every magnet. When gluing, ensure the marked side is facing inward (hidden) so that every miniature in your collection attracts to your storage trays, rather than repelling them.

Step 5: Bonding the Magnet

Apply a single, small drop of cyanoacrylate glue into the recessed hole. Press the magnet into place using the back of a hobby knife or a non-magnetic tool. Ensure the magnet is seated flat. Allow the assembly to cure for at least 30 minutes before testing the magnetism; early testing can pull the magnet out of the still-wet adhesive.

Troubleshooting Common Magnetization Failures

Understanding how to recover from improper installation is essential for maintaining a collection that is safe for travel.

• Magnet Falling Out Post-Curing: This occurs when the adhesive fails to bond with the smooth surface of the plastic base. Actionable Fix: Remove the magnet, use a file to roughen the interior of the hole, and re-glue using a gap-filling cyanoacrylate gel rather than a thin liquid glue.
• Miniature Repelling from the Tray: This happens due to reversed polarity during installation. Actionable Fix: If the glue has fully cured, it is difficult to remove. Use an industrial-strength debonder to soften the adhesive, extract the magnet, flip it, and re-install with the correct orientation.
• Wobbling on Flat Surfaces: This occurs when the magnet sits lower than the rim of the base. Actionable Fix: The magnet is too large for the recess. Carefully sand the bottom of the base rim down slightly to ensure the miniature rests on the rim, not the magnet.

Frequently Asked Questions

Is it necessary to use a primer or sealer on the magnets?

No, neodymium magnets are typically nickel-plated and resist corrosion well. However, if you are playing in a high-humidity environment or using corrosive materials, applying a small amount of spray primer over the exposed magnet surface after installation adds an extra layer of protection.

Can I magnetize pewter or white metal miniatures?

Yes, but metal miniatures are significantly heavier than plastic. Use a larger 5mm or 6mm magnet and ensure the surface of the base is scored deeply to allow the adhesive to create a strong mechanical bond, as metal base material is denser and less porous than plastic.

Does the magnetic field interfere with painting or clear coats?

Magnetic fields do not affect acrylic paints, enamels, or matte varnishes. You can safely magnetize your miniatures before or after painting, though magnetizing before painting allows you to use the magnet as a handle to hold the miniature while you work.

What is the best way to store magnetized miniatures?

The industry standard is to use a flat plastic storage bin lined with galvanized steel sheeting or adhesive magnetic foil. Avoid using flexible rubberized magnetic sheets for the base of the bin, as these are often too weak to hold heavy miniatures securely during transit.
