Back in November, Do3D.com was having their Black Friday sale and offering deep discounts on all of their printable prop models. While I already had a lot of things in the pipeline, the files were priced so cheap I couldn't resist the urge to stack up a bunch of things to keep the printers running during the idle time between more important projects.
One of the models I got was their rendition of Jarnbjorn*, Thor's axe as depicted in the Sideshow Lady Thor statue:
Since I'd already made the comic book version of this costume (build details here: LINK) I figured I might as well add this one more prop weapon to the wall of potential armaments for her to carry. The axe is pretty sexy on its own:
Considering the steady stream of rayguns and robot parts I've been making, it would be nice to do something a little more analog for a change. Plus, I have a stark shortage of melee weapons on the big wall of prop weapons. This beast was just what the doctor ordered.
The modelers at Do3D did a pretty good job of translating that sculpt into the digital realm:
Printing the Head:
The head of the axe was way too big to print in one piece. Instead, over the course of a few days, my fleet of Zortrax M200 3D printers grew the head as a series of separate chunks. Here's the digital layout showing one of the first pieces set up in the Zortrax software:
After printing six or seven such chunks and gluing them together with copious amounts of CA glue, I started adding primer and had the printed head mostly done:
Printed with about 30% infill, the head of the axe was a good compromise between strength and weight. A carefully balanced notion of low cost and durability. That's all well and good since I would not likely be using it to cleave the heads of dark elves invading the nine realms.
Making the Handle:
If the handle was going to be 3D printed as well, it would need some kind of reinforcement to keep it from breaking whenever someone gets overzealous about brandishing it.
So what to use for handle reinforcement? After noodling over a few options for printing it hollow and filling it with resin or fitting it with a metal rod or wooden dowel, I started thinking of all of the additional work I'd need to do in order to smooth out the print lines. Then I'd still have to prime, prep, and paint on a convincing wooden finish. Then I'd have to pick out all of the leather parts and paint them to look the part as well. In the end I decided that there was no really good reason to print the handle at all. I would do something different. Something new. Something completely revolutionary.
I would build a wood-looking axe handle from scratch. Out of wood.
I know, I know. It sounds crazy, but I actually had all of the necessary technology close at hand. My friend Mark works at a mill that makes custom trim and molding for home restoration contractors. I asked him to keep an eye out for a suitable scrap of something pretty-ish. He managed to find me a six foot piece of cedar 4x6 that would do nicely.
To make my initial cut for the shape of the handle, I printed out a side view of the 3D model scaled up to lifesize. Then I laid it out and traced it onto the big ass cedar plank:
Because I'm lazy and the bandsaw was in a whole different building, I made the initial cut with a jigsaw instead. This meant that I had to make the cut on both sides and I ended up with an understandably ugly edge:
I did the initial rough shaping the end of the handle with a rasp and a knife. Eventually it was a good fit for the head of the axe:
My plan had originally been to round out and taper the handle with a spokeshave or a draw knife. But digging through my father's odd assortment of antique woodworking tools, they turned out to be a bit rusty and way overdue for a sharpening:
Since I really wasn't in a sharpening and stropping mood, and because the open grain of the soft cedar wood would make it a tricky proposal at best, I opted to skip the spokeshaves. Instead, I did more rough shaping with a rasp and a drywall knife. This is the decision of some sort of deranged person, but it was late and I was on a roll.

I'm pretty happy with the results. Wood is pretty:
The next day my nephew stopped by the shop. He was pretty happy with the results too:
After sanding the handle down to 220-grit, it looked about like so:
Of course, the handle of Jarnbjorn shouldn't look like a buttery soft chunk of cedar. Instead it should look like it was hewn from something mightier than oak by dwarven forgemasters of Nidavellir over a thousand years ago. Fortunately, Minwax makes that exact color:
Once the stain was set, I went ahead and laid on a few coats of satin polyurethane finish to even out the sheen and toughen up the surface of the handle.
With the shape, shade, and sheen all figured out, it was time to start adding the remaining details. I started with the faux iron rings. These began as strips of scrap ABS plastic I had laying around:
Each strip was pre-bent to help it sit properly in place:
Once they were fitted, the excess length was trimmed off;
They were glued in place as well as nailed with furniture tacks:
The final detail was a styrene half round fitted along each edge:
At this point, the whole thing was really starting to look the part:
The metal rings were painted with a few coats of hammered metallic silver paint:
Once the paint had dried, it was time to take off the masking tape and get to the leather parts.
Fortunately, I tend to have sacks of leather scraps kicking around in storage for no particular reason. For the grip section between the iron rings, I used a soft, black buckskin leather like so:
For the brown binding, I had a strip of thicker cowhide that looked to be the right color:
And lo, the handle was maked:
Painting the Head:
Meanwhile, the head still looked like a 3D printed, chintzy piece of crap. After a few coats of primer, I gave it a cheap coat of rattlecan silver and instantly regretted it:
Still not loving it, I gave the whole thing a blackwash:
I guess it was a bit better:
The other nephew thought it was cool:
But still, I felt it needed to be better looking. That may be due in part to the fact that I've been messing around with a lot of stuff like this:
While Jarnbjorn wasn't especially shiny in the statue, I couldn't shake the notion that this was supposed to be an axe wielded by a god, forged by the mythical master weaponsmiths of Asgard and blessed with the blood of Thor himself. It shouldn't look quite so shabby.
So I went ahead and stripped off the paint, sanded everything down to 600 grit, and gave it a nice glossy coat of black:
Once that was done curing, I dusted on a nice, shiny coat of Alumaluster:
A little while later I was working on an unrelated project that needed some gold candy coat. So once those parts were sprayed, I broke out a brush to pick out the inlay by hand:
Then the whole thing got a couple coats of automotive clearcoat and finally, when the axe head was installed on the handle, it was given another blackwash to take just a bit of the shine off of it and give it the look of a relic worthy of a place of honor in the armory of Asgard:
In this case, the black was a flat black oil-based paint and the thinning and wiping was done with mineral spirits. This isn't an option with normal hardware store spraypaint because the thinner is likely to mess up the finish, but the automotive urethane clearcoat is stable enough to be unmarred when the thinner is wiped off with a rag. The end result is a nice, durable finish that won't rub off quite as easy as an acrylic blackwash. It makes me happy:
One of these days I'll get the Lady Shawnon dressed up in the Thor costume and do another location shoot. In the meantime, here's Jarnbjorn in all it's glory:
It's still a bit tricky to find a "natural" backdrop that showcases all of the different colors and textures:
But having taken a few photos, it was time to test it out:
The Lady Shawnon tried it out too:
Before anybody gets too excited about us abusing my poor dog Leeloo, know that she wasn't even the least bit frightened and the only way to get her to run for these staged photos was to kick a ball for her to chase. You can see the ball in this failed attempt:
And when it was all said and done, she remained perfectly happy and healthy:
Jarnbjorn, meanwhile, will rest amongst the pile of recently finished things until I find a better place to display it:
FINIS
*In Old Norse, "Járnbjǫrn" means "Iron Bear." Now that's a thing you know.
