Fallout SMG Prop Build Part 2

by | Jun 2, 2017 | Fallout Props, Science Fiction Props, Tutorial, Workshop Blog | 0 comments

By the end of Part 1 of the Fallout SMG prop article I had just started construction of the receiver of the gun. This left me in the enviable position of being able to work on all the detail parts and the various greblies. Whoever designed the 10mm SMG from New Vegas went to town on the details compared to the other guns in the game, which tend to be a bit more functional looking. The 10mm SMG isn’t the most elegant of designs, but it has a rugged, almost Lego like aesthetic, which has always appealed to me. Anyway, on with the build.

Fallout SMG Prop build – The Details

Fallout SMG Prop rear sight details

The rear sight assembly on the in-game gun looks like a simple folded steel affair. Though, weirdly there is only the frame of a sight and no actual internal ring or notch as you would expect on a real firearm. I constructed my rear sight from layers of 3mm MDF, with details being provided with a couple of woodscrews and washers.

This gun is covered in rivets for some reason and my favourite method for producing fake dome rivets is to use furniture tacks. When you build a lot of Warhammer 40,000 props like I do, you end up with a pretty good selection of rivet approximations around. In the grim darkness of the far future, they’ve forgotten how to weld.

The tacks have been added to the forward receiver of the SMG. I like to drill a 1.5mm pilot hole and use super glue to make sure the tack is extra secure.

Fallout SMG prop magazine parts

The magazine for the Fallout SMG prop is made up from 3 pieces. The central core is a lamination of 12 and 6mm MDF. Whereas, the outer faces that contain the detail are constructed from 3mm MDF. After the details cuts are made to the outer pieces, all 4 parts are laminated together to form a mildly toxic sandwich that’s high in fibre.

The long slots in the magazine side panels were cut out with a coping saw. It is best to start the cuts out with an appropriately sized hole drilled at the start of the sawing path.

Here is the magazine, assembled and ready for filing/sanding.

The lower receiver has a couple of recessed, flat bottom holes. The best tool for this job is a Forstner bit in the pillar drill. Failing that, a regular bit or spade bit could be used, but you’ll have to fill the bottom of the hole. Are we not doing phrasing anymore?

Here you can see the recess in the handgrip has had a washer added, as per the in-game model.

I had just purchased first 3D printer as I started this project, so naturally I had to make a couple of parts for the Fallout SMG Prop. The muzzle of the SMG is a fairly straightforward part and could have been produced in a number of ways, but I wanted to play with my new toy.

I designed the part with a countersunk hole to allow the attachment of the muzzle to the gun with a woodscrew. I won’t go into detail here about how I cleaned up the 3D print, as that would be better kept for another article. There’s no great secret here, just lots of sanding and filler.

The rear retaining screw part of the Fallout SMG prop was made from a piece of 12mm MDF, shaped and tapered using my belt sander. Here you can see where I got it all wrong by letting the drill bit wander. I should have drilled the hold first, and then shaped the sides.

Here is the part, sans the fuck-up! The lesson to be learned is that the order in which we undertake each of the processes when shaping a part can have a considerable impact on the accuracy of the final part.

The rear of the receiver was shaped with my belt sander and palm sander as needed. I then filled the exposed grain with thin super glue and gave it another light sanding. MDF can be a little temperamental if you leave edge “grain” exposed, so it’s often a good idea to get a good, hard, sandable covering on the outside face. I often use Shellac for this purpose.

Here is the whole rear receiver assembly.

The front of the Fallout SMG prop has a weird cage thing around the muzzle. I constructed this from 8mm acrylic rod. Plastic rod can be formed quite easily using heat, in my case I used a heat gun. As you can see from the picture, I constructed a jig that would clamp the end of the rod down whilst I bent the rod around the internal former. On my first attempt, I melted the surface of the rod on the 4th With this kind of thing, there is often a little bit of trial and error involved.

After gluing the ends of the hoop part of the cage together, I rounded the ends of the 4 “legs” with my Dremel and attached them to the hoop. I used 1mm piano wire as a in to hold both pieces together. This provided a very solid structure.

Here you can see the final cage assembly in place on the Fallout SMG prop. I used the same 1mm piano wire to pin the cage to the gun.

This picture is a little out of sequence as I had to wait for a new delivery of Kneadatite. For those unfamiliar, Kneadatite is a two-part epoxy putty that is used by miniature sculptors, and is similar to Milliput or Apoxie Sculpt. I used a small amount of this putty to simulate the welds around the cage area. I’m not so great with the sculpting tools and this is an area that I’m not completely happy with. As you will see in part 3, it look alright once the paint is on the gun, but my sculpting skills clearly need some work!

With the gun completely assembled I could start looking forward to painting the Fallout SMG prop. Part 3 of this build log details the process of sealing MDF (less fun than it sounds) and painting the gun to look like it’s had a hard time in the Mojave wasteland.
