It feels good to be able to build some stuff for myself again! The Daft Punk helmet was my last active commission for a little while, and for the next few months, I’ll be concentrating on personal projects…. like this one.
I’ve been a huge Mass Effect fan for a while now, and with the release of the second game I knew I wanted to take a crack at building some of the weaponry from the ME universe. As a bit of a personal challenge to myself, I decided to construct this gun from as much of my existing materials as possible. That is to say, 95% of what you see here is scrap I had in my shop from other builds. In the end, the entire piece only cost me $28 in raw materials.
So, here’s how it came together.
First off, as with everything I make, I drew up some blueprints. Those with a keen eye may notice that my illustrations don’t match up 100% with the reference image above. This is because the M8 in the game renders and the M8 on the box art have several differences. My version above is an amalgamation of the two.
I had a huge honking sheet of 3/4″ MDF left over from the Laser Rifle project; Onto this I sketched out the various parts. My plan was to have a central “spine” that all of the outer components would slide onto, forming the organic shape of the M8.
Next step was to glue and clamp these pieces together around thin strips of MDF that would serve as the center sections. This would eventually leave these pieces looking like a bunch of u-channel MDF chunks.
Additional details were added by either shaving down the existing blocks, or by adding 1/4″ MDF pieces to the outside of the forms and taking away from those. The ability to remove whatever piece I was working on from the center spine was a HUGE help in shaping these.
I also used some more scrap styrene to vac-form the scope assembly that sits on top of the upper receiver. These were formed around MDF bucks, and the dome shape on the sides was made from vac-forming the end of an engraving tool handle cap.
I also busted out the lathe to take care of the scope and the small cylinders on the right side of the gun. The scope from laminated sheets of MDF, and the cylinder master was made an old banister support. Really.
For the “grip” on the scope, I found some leftover rubber material used to line the insides of toolbox drawers. I think this was part of another project, but my toolbox drawers are also without liner, so who knows?
I decided I wanted to have the gun light up red in the sides and on the scope as it does in game. Additionally, to simulate “muzzle flash” I would add 3 LEDs to both barrels which would illuminate when the trigger is pulled. I added a small pushbutton switch at the front of the trigger to make the lights work, and for the battery compartment, I scrounged a double AAA cell holder from an old XM Radio remote control. This was countersunk into the handle.
THIS PIECE TOOK FOREVER! Oh man, the angles… It was very convenient to be able to shape pieces since I could remove them from the gun, but because nothing ever went back on exactly as it did before, a lot of times the alignment would change in test fitting, and I’d have to shave the edges down or move things around again. The result you see here – three pieces of styrene, took me almost an entire evening to get right.
I didn’t want to go buy any perfboard, so I once again reached into the scrap plastic bin for more styrene. By drilling holes and routing the leads of the LEDs in a weird little maze, I was able to make some halfway decent little dead bug boards. I made 2 for the barrels, one for the center section, and another for the scope light.
A few more details needed to be added in styrene. The vents in the front grip aren’t perfectly canon, but since this was a personal build I decided to add my own touch to it. Also, I cut the gap way too deep on that center section, and this was the best and fastest way to hide it! A great teacher of mine once said “Celebrate the Intersection. The more you try to hide something, the easier it is to see” Also… the small barrel there is an old ballpoint pen.
Onto paint! I had scrounged some free Ace Hardware offbrand from an old job at my office, which served as the rather bright silver basecoat. To tone this down, I dusted it with Rustoleum hammered spraypaint, then Krylon clearcoat. The gunmetal color you see here is the result.
The upper front receiver, rear stock, grip, and front grip were all painted with Plasti-dip spray to give them texture and a rubbery feel. This was another expenditure… up to nearly $10 now. All parts not painted with silver or plasti-dip got satin or flat black, depending on their location.
To control the electronics, I returned to the dead RC car and stole the switch from it. It even came with a nice plastic housing! This was placed in the scope mount. As you can see, i didn’t have any shrink tubing handy… so the leads were isolated with hotglue. Horray cheap budget electronics!
It looked good, but needed weathering. First though, I called up the shop that does all my vinyl – Signs Now Atlanta – and had them cut some stencils for me. I designed the decals for the M8 in illustrator, and the guys at Signs Now cut them in vinyl for me to use as templates. After sticking the vinyl to the piece and painting over with enamel paint, the mask was removed to show clean, crisp lettering! The nice part about this is what they’re more permanent than vinyl decals, and I can control how “weathered” the paint will be.
After that, it was time to weather it. I spent some time recording the entire weathering process for those interested, and in the coming weeks I’ll be editing that into a time-lapse video to show the overall technique I use. Don’t expect magic though, mostly it just looks like this:
My initial pass was a bit heavy with the dirt – my favorite comment about it was “I don’t think I’d trust the fate of the universe to someone who doesn’t know how to clean their gun.” This was a good point.
