DIY paint drying oven - Dremel

Quick dry painting oven

I know that I saw this quick dry painting oven done somewhere ages ago, but couldn’t find the instructions for it. In true Spruegrey fashion, I just bashed together a solution that fits the bill nicely. Interestingly enough, this is the first post that I have ever written that comes with health warnings!

Tools required

DIY paint drying oven Tin can – With a baby who’s just gone off formula, we have an excess of these. Milo also has a brilliant tin ideal for this use. I wouldn’t want a tin that has an open top larger than four to six inches as we have to position the heat source over the top. This is the oven part and will be used to dry paint on miniatures. The width and height of the tin should be able to accommodate the size of the models that you are going to be drying.
Dremel with cutting disk. I have owned a Dremel for many years and only get limited usage out of it, typically for sanding bases and large models. The cutting disk is just that and spins (in this case at 10000 RPM). DANGER: The disk spinning that fast can injure you. Make sure to wear protective glasses as there is the risk of small pieces of metal getting in your eye or, in extreme cases, of the disk shattering and hitting you. You have been told. Seriously.

DIY paint oven - Sharpie and Gaffer Tape Gaffer Tape. Silence is golden, but gaffer tape is silver. Gaffer tape is like the Force; it has a light side and a dark side and holds the universe together!
A Sharpie (or any permanent marker) is used to mark out the section to cut out that will form the door.
Modelling knife used to cut the tape. If you can’t be trusted with a sharp knife, you can use scissors to cut the Gaffer tape. Or get parental assistance.
Desk lamp (not pictured) – This will be placed on the top of the finished product to act as a heat source for drying the painted miniatures.

Our list of tools isn’t massively specialised with the exception of the Dremel. You could drill and cut the can anyway that you see fit. I found the Dremel easy to control and very precise. A note on cutting disks. They come in a variety of thicknesses and the one that I am using is about 2mm thick. This works really well as we’ll see later because I do need a gap between the door to the oven and the rest of the tin.


Now the fun begins. You take your Dremel or chosen cutting device and start hacking away! Apart from possibly casuing injury, this won’t work out so well. Before the real fun begins you need to mark out the section of the tin can that will be removed as the door. The right size door should accommodate both your hand and the largest miniature that you’re likely to want to rapidly dry paint on.
The cutting process may also generate small bits of metal that fly off, so again, exercise caution.

Post cutting out comes your second health warning, the cut out and the tin can will be sharp, so be carful about cutting hands and fingers. Which is where the Gaffer tape comes in …

Use the Gaffer tape to cover the sharp edges of both the door and the tin. Using a 2mm cutting wheel means that there is just enough gap to accommodate the layers of tape on the door and on the tin while still allowing the door to fit cleanly back in place.
Once all the sharp edges are safely hidden away come attaching the door.
The hinges are just strips of Gaffer tape stuck to the inside, attaching the door to the tin and the outside as well. In the long term, this could be the one part that fails as exposure to high(ish) temperatures could make the tape brittle. In that event, just remake the hinges from more tape.

Lastly, and here’s where the fun really begins, we need to apply heat. This could come from a number of sources. From past experiments, I would NOT recommend a hair dryer. Just trust me.

Our oven uses radiant heat from the desk lamp which is positioned low over the open top of the oven. This will heat the inside and rapidly dry paint on the miniatures within. There is a risk that the tin can will also grow hot as it absorbs radiant heat. It should be possible to insulate the can, or use more Gaffer tape around the outside of the can to cover any exposed metal. I think …

Total construction time was about two hours

That involved fiddling around with the Dremel, testing the cutting wheel and applying the Gaffer tape.

Poor Warpig was chosen as the first larger model I could get my hands on to demonstrate the scale of our, now finished, rapid-paint-drying-miniature-oven-thing.

If anyone knows where the original idea came from, I’d be glad to post credit where credit is due.
