How to Magnetize Tabletop Vehicles Properly
Share
A vehicle with a turret glued at a slight angle or a gun option you no longer use can be frustrating after hours of assembly and painting. Learning how to magnetize tabletop vehicles lets you keep the model you like on the table while changing loadouts, removing fragile parts for transport, and making storage far less risky.
For most hobby vehicles, the goal is not to put magnets in every moving part. It is to create strong, repeatable connections where the model benefits from them: main guns, sponsons, missile racks, pintle weapons, dozer blades, flying stands, and removable passengers. A clean magnet job should look intentional, hold securely during play, and let you swap parts without scraping paint.
Choose the right vehicle parts to magnetize
Start by looking at the kit as a gaming piece, not just a display model. Weapon choices that share one mounting point are the best candidates. A turret that can take several barrels, side weapons with alternate options, or a roof hatch that can carry different guns are all straightforward projects.
Transport is another good reason to magnetize. Long antennae, wide wings, fragile exhausts, and flight stands are often more likely to break in a case than during a game. Making these pieces removable can save repair work later, particularly on larger 3D-printed vehicles with detailed add-on parts.
Not every joint needs a magnet. If a part has one obvious build option, is deeply recessed, or will never be removed after painting, glue is usually stronger and faster. Magnetizing works best when it solves a real assembly, storage, or list-building problem.
Tools and magnets for tabletop vehicles
Neodymium magnets are the standard for miniature work. They are compact, strong for their size, and available in many diameters and thicknesses. For smaller weapons and accessory mounts, 2 mm magnets are often enough. For main guns, heavy turrets, or larger removable sections, 3 mm to 5 mm magnets may be more appropriate.
The right size depends on the weight of the component and the amount of contact area available. A thick, heavy resin or printed cannon may need two magnets, a larger magnet, or a hidden support peg in addition to magnetic force. Do not assume that one very strong magnet is always the best solution. Oversized magnets can crack thin parts, pull free from shallow sockets, or make removal awkward.
Keep these tools on the bench before you begin:
- Neodymium magnets in matched sizes
- A pin vise or hobby drill with drill bits
- Cyanoacrylate super glue
- A hobby knife and small files
- Green stuff, milliput, or another gap-filling epoxy
- A permanent marker or paint pen for polarity marks
How to magnetize tabletop vehicles step by step
Plan the connection before drilling
Dry-fit every option first. Identify where the weapons meet the hull, turret, or mount, then look for the thickest hidden area that keeps the part correctly aligned. On a turret weapon, this may be the rear of the gun housing and the inner turret face. On a sponson, it may be inside the arm joint rather than at the weapon itself.
Mark a center point with the tip of a hobby knife. This small pilot mark stops the drill bit from skating across smooth plastic or cured resin. If the kit has an existing peg, consider trimming it down and using it as an alignment pin while the magnets handle the hold. This is especially useful for weapons that must point straight ahead rather than spin freely.
Drill shallow, test-fit holes
Use a drill bit that is close to the magnet diameter, then drill slowly. Your hole should be slightly deeper than the magnet thickness so the magnet can sit flush or just below the surface. A proud magnet creates a visible gap and puts extra leverage on the joint.
Test the magnet in the hole without glue. It should fit snugly, but you should not need to force it in. If the hole is too loose, a small amount of epoxy putty can create a secure bed. If it is too tight, widen it carefully rather than pressing hard enough to split the part.
For hollow 3D-printed components, drilling may expose an interior cavity. That is not a failed project. Fill the cavity behind the magnet with epoxy putty, let it begin to firm up, then press the magnet into place. This gives the adhesive and magnet a solid foundation instead of a thin printed wall.
Check polarity every single time
Polarity mistakes are the most common magnetizing problem, and they are avoidable. Create a magnet stack and mark one outward-facing side of the stack with a paint pen. Keep that orientation consistent for every vehicle weapon and mounting point in the project.
Glue the hull or turret magnet first. Then attach the second magnet to it magnetically, apply glue to the receiving hole on the weapon, and press the weapon into position. Once the glue has set, the two parts will attract correctly by design.
Do not glue both magnets separately based on memory. A single reversed magnet can turn a finished weapon into a tiny repelling battery, and removing a strongly glued magnet from a painted part is rarely enjoyable.
Secure the magnets without fogging the model
Use a small amount of super glue around the sides of the hole, not a large puddle underneath. Too much glue can push the magnet above the surface or leave a glossy mess around the joint. Press the magnet in with a nonmagnetic tool if possible. Metal tweezers tend to pull magnets out of alignment at the worst moment.
For demanding connections, add a thin ring of epoxy putty around the back of the installed magnet. This is worthwhile on large gun barrels, removable wings, and turrets that will be handled often. Let the assembly cure fully before testing the connection. Fresh super glue can appear solid while still being vulnerable to twisting force.
Strong joints need alignment, not just pull force
A magnet holds parts together, but it does not automatically stop them from rotating. This matters on long barrels, raised missile launchers, and anything that sticks out from the vehicle. If the weapon droops or spins, add a short plastic rod, trimmed kit peg, or square tab beside the magnet. The pin controls the angle while the magnet keeps the part attached.
Two smaller magnets set apart from each other can also prevent rotation better than one larger central magnet. This works well on wide turret rings, removable side panels, and aircraft-style wings. It requires more careful measuring, but the result is much more stable.
For a rotating turret, use a larger magnet in the hull and turret base, then add a central guide peg if there is room. The peg keeps the turret centered while the magnets allow it to turn. If you want the turret removable only for storage, a firm friction fit may be enough, with magnets reserved for the gun options.
Paint after testing every option
Before priming, assemble every magnetized configuration at least once. Check that weapons sit level, doors close properly, turrets rotate, and the vehicle can be picked up without parts falling away. Make adjustments now, when you can still drill, fill, and sand without risking a finished paint job.
During painting, keep the magnet faces clear of thick primer and paint. A light coat usually does not hurt the connection, but repeated layers can reduce the contact between magnets and create a visible gap. If paint builds up, gently scrape the contact surface with a hobby knife or use a fine sanding stick.
Paint each interchangeable part alongside the vehicle so weathering, dust, and edge highlights match. Swappable weapons look most convincing when they appear to belong to the same machine, not like spare components from different projects.
Common tabletop vehicle magnetizing mistakes
Weak joints usually come from magnets that are too small, shallow holes, or a heavy part hanging too far from the connection point. Upgrade the magnet size only after considering a support pin or a second magnet. Better alignment can solve the problem without turning the assembly into an awkward, oversized joint.
Crooked weapons are usually a planning issue. Re-drilling a slightly misplaced hole is possible, but it is better to use the dry-fit stage to establish a visible centerline. Look at the vehicle from the front, side, and top before the glue cures.
Finally, avoid leaving loose neodymium magnets around children, pets, or your hobby workspace. They are small, easy to misplace, and dangerous if swallowed. Store them in a labeled container and keep them away from electronics and finished painted miniatures until you are ready to use them.
A well-magnetized vehicle earns its place in more armies, more missions, and more games without demanding another full build. Start with one turret or weapon mount, take your time with polarity, and let the next vehicle benefit from what you learn at the bench.
