Magmace

The Magmace: 6.8 pounds of cold-rolled, Krylon-coated, All-American neo-medieval whoop-ass.

This project has been sitting around my workbench for a month or two. The prototypes were among the first objects I printed on my Replicator, and I finally got a chance to assemble and photograph the whole kit and caboodle.

This one is laser-cut out of 3/16″ steel plate by the fine folks at Ponoko. You can buy one in plastic (inexpensive) or steel (awesome) direct from Ponoko.

Who needs one of these, besides me? This Venn diagram may help clear things up:

You’ll also need a Maglite. I’ve got mine attached to a 6D-Cell model. It should fit on a 3-cell, but doesn’t look anywhere near as impressive.

You’ll also need a pair of hose clamps, which you can find at your local hardware/auto parts store.

I used a #28 hose clamp for the Maglite shaft and #36 for the head. The shaft has a diameter of 40mm and the head’s 52mm, if that helps you find the right clamps in your locality, or you can take advantage of the global supply chain and get them from Amazon.

Thingiverse has a policy on deadly weapons, so I’m not hosting it over there with all of my less dangerous designs.

It took a few tries to get the prototype correct because I didn’t have a reliable way of measuring the curve of the Maglite’s head. After some false starts I tried bending a piece of solder to conform to the outline of the flashlight and flatbed scanning it. Success.

The original design called for using a set screw shaft collar from McMaster-Carr as the attachment device, but that was too heavy and expensive.

You can download STLs of many parts from McMaster-Carr. I don’t know what their plan is for staying in business once everyone has a 3D printer in the home.

The next step is having it laser-cut out of cold-rolled steel from Ponoko. It arrived a few days later in a cute little cardboard box that had the word “Yay!” printed on the outside.

Yay, indeed.

The steel flanges arrived with a little bit of surface rust on them, which is to be expected with this material, but check out the precision on these cuts.

A few swipes with some steel wool and a little black Krylon spray paint, and the flanges are ready for attachment.

The magmace isn’t a toy; you could really mess a dude up with one of these, even if you printed it in ABS plastic or had Ponoko cut you one. It makes a great conversation piece, but the last thing I need is hearing about someone who had one too many flagons of mead and hospitalized his dungeon master with this. For all I know it may be illegal in some jurisdictions.

You can take this out to show your friends at parties, but please don’t whack people or animals with it.
