The mighty (EVA foam) Mjolnir COMPLETE!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A friend of mine is doing a Thor crossplay, and she asked me if I could build her the signature weapon. Since I can't really say no to a friend, I obliged...

I marinated on the construction for a while but finally settled on building it out of material I have plenty of at the moment, EVA floor mats and foamies. I weighed the options of an all wood build, but honestly, getting that many angles and surfaces uniform with a sander wasn't something I wanted to tackle on this build. There are already so many other great examples of Mjolnir out there, that I really didn't need to reinvent the wheel. I found a drawing on a Wiki page giving the approximate dimensions from the first film and set out to build it to that scale.

First step, cutting out all the pieces and getting them all to the same size.

Went to work with a hot knife with a soldering tip and burned in some details. I cleaned up the deeper grooved areas with a small sanding drum on my Dremel

Next up were the end caps that started life like this...

Then through the magic of a sanding block, some 220 grit paper and a little elbow grease, became this...

A hole was cut for a piece of 1" PVC pipe and an end cap glued on. I taped the other side on to keep it all square while the glue set up.

Then I filled the cavity with some expanding foam so it wouldn't want to collapse onto itself if it got played a little too rough with.

(And thanks to some comments on this build over in the Facebook RPF group, I now want to build another one to use as a Popcorn bowl)

After the foam set up overnight, I shaved down the excess and glued the other cap on. I also started carving out some weathering marks on the handle, as well as digging in small grooves around it every 1" or so to slightly recess the foam strips I would use as the handle's ribbing.

Then it was time to turn my attention to the "carving" around the hammer. some 3mm craft foamies, a little puffy paint and...voila.

Next up were the runes on the top disk. I scaled and printed out the runes to the right approximate size, taped the printed paper onto the disk, then "traced" all the runes with a really sharp X-Acto blade. After some heat was applied, this happens.

(mental note, do this BEFORE you attach it to an area that's already been glued down, otherwise you'll end up melting all the hard work you did getting seams to look good)

Then it was onto the pommel. I realized I'd worked myself into a corner with this but it was too far done at this point to really do anything about it. In hindsight I should have cut the coupler off and added a PVC cap to build onto, but I had an idea in my head when I first thought to use it that turned out to be much more difficult a task than I anticipated with the materials I had on hand. SO...I made something up. Using some Apoxie Sculpt and a little imagination, I came up with this.

Not the crowning jewel in my portfolio, but it gets the job done and my friend loves it, so I guess I can be OK with it....Until i build the next one. ;)

And that's where I ended up with it so far. I need to seal it with a couple coats of Plasti-Dip, fill in some seam areas around the face with caulking and then give it a good coat of filler primer to get it smooth.

Stay tuned.

Holy crap! That looks excellent!! I've been wanting to make one of these but the wood process would be to hard. I didn't think foam would work.

It's stupidly simple to build out of foam. I had some really thick (1/2") mats I bought a while back that I tried to use for armor, but they don't like to bend and it's a royal PITA to cut anything but a straight line (hence the god-awfully horrific angled cuts on the endcaps). Since everything on this is more or less squared-up edges, it was pretty easy to knock the basic design out with it. The larger flat ends measure up at 6x8", and the smaller strips that bind them all together are 1x8". Once it's all glued together with the end-caps, the head is roughly 7x9".

Excellent trick with the runes on the end cap, that turned out fantastic!

Thanks! I've done that trick before for bullet-hit battle damage on my Cerby armor, but I really wasn't sure how it would come out on such a small scale. My original plan was to just write the runes with a ball point pen a few times. I tried the first word, and really wasn't happy with the result.
The cuts are all shorter than the width of an X-acto blade. No one is more surprised than me that it came out so well.

Got a little bit done over the last few days in between working on my Cerberus Armor.

It's completely sealed, Plasti-dipped, and all the holes and gaps have been hit with caulking. I'm currently working on the second stage of the faux finish on the handle. With any luck, it will look like battle worn leather when I get done.
Without any luck, it'll look like battle worn wood.

Next step is some filler primer and light wet sanding on the body of the hammer, and then final paint.

Primed last night with black, and the first coat of silver went on the head today.

This is a Rustoleum hammered/textured nickel silver.
It leaves a pretty nice patina behind that should lend itself to how I intend to weather it.

You an see a bit of the texture here (pardon the drips. I've never worked with this stuff before and laid it on a little too thick at first...)

Detail work commenced...

Doing my best to simulate old leather for the handle using multiple layers of acrylic paint

And giving the puffy paint some depth with a simple black wash

Thanks everyone!

As for the budget...

$10 / 4 2'x2' sheets of foam floor mats
$1 / 1 sheet of 3mm craft foam
$12 / Various spray paint
$4 / 1 stick of 1 1/2" PVC pipe (10')
$10 Apoxie Sculpt
$6 / 1 can of expanding foam
$6 / 1 can of Plasti-Dip

Add in the various glue and caulking and you're looking at about $50 total to make this one. But with what's left over from the initial purchase, I can make at least 3 more and only have to outlay more money for 1 can of Plasti-dip and 3 more cans of Expanding foam. If you figure it out over 4 total builds, that's less than $19 each in material.
