Fallout 4 Railway Rifle

So, let me preface this by saying this is my first large(ish) scale build i have ever attempted. I'm planning on building the fallout 4 version of the railway rifle. I don't know why but in playing through the game the sheer damage i could do and the lovable little toot-toot! of the train whistle on each reload made me fall in Love with this gun. As such, I've decided to attempt it. I also realize, that this being a challenging build, I'd need as much help as possible.

So in starting this build I realized that the game devs so kindly gave us a yardstick in the game, making finding measurements much easier. All in all, this gun is gonna be about 31 inches, or 79 cms in total. My first thoughts on beginning this build are making the stock first and making it extend the entire length of the rifle. (I also thought it would be fun to find what wood is native to Boston for that added bit of realism.) The majority of the body I'm thinking of building out of PVC. I don't really have access to a 3D printer and have little to no talent in operating 3D imaging software.

For color i was thinking of applying aluminized tape to the whole thing sans the stock and then sanding and "steel-wooling" the hell out of it to take some shine out. Then attempting to paint on a rust-like weathering.

This gun is going to be as accurate as i can make it in size, weight, feel, and look; but above all, it absolutely Must be able to make the train whistle sound when i close the top lid to "reload." I want document as much of this as i can and keep anyone interested updated in my progress. I'll happily share plans and anything else i've found along the way. I suppose what I am asking the RPF community for is; What would you do differently? What materials would you use and where would you get them? Keep in mind I have only an idea of what how i want to do this, and i recognize that its all subject to change. I need all the help i can get. Thank you!
 
Subscribed! I love the native Bostonain wood idea. McMaster-Carr has a bevy of different materials. I used a huge piece of Delrin, aka acetal, for my project. Not cheap but highly machinable. Just as a primer.
 
I thought you meant "yard stick" as a expression of speech, and then I remembered that a yard stick is literally a prop in the game.

Don't worry about CAD or 3D printing for the railway rifle, it is meant to be hand-built. (Also while CAD is awesome, I seem to get less built in the real world than I did before I knew CAD)

You can use a real gun stock or the back, I have seen many prop makers buy them on eBay. Aces used one for the base of his Laser Musket build.

Aluminum tape works well on small details, but if you want to wrap a whole surface, using a heavy aluminum foil and an adhesive helps to minimize the number of seams.
I wouldn't make the gun accurate in weight, we don't have working power armor yet. A foam interior will reduce the weight, you can hard coat the foam with plastic or fiberglass.

You should look up some of the many small scale steam engine builds that people have done, there has to be a mini train whistle out there. You could use compressed air to drive the whistle instead of hot steam. If you got that far and wanted actual mist coming out, an alternative to hot-steam is to use a ultrasonic mist generator.
 
While i do love the idea of a real honest to goodness train whistle in the workings that kind of engineering at this point is far beyond me. i was thinking more along the lines of an mp3 player that would be triggered to play whenever i close the lid. As for the weight, yes you're absolutely right We don't have the working power armor and that is a problem :). However, i meant more along the lines of a good feeling weight (sorry should have been specific.) I want it to feel right and balanced in your hands.

Thank you for your advice on aluminum foil! And hard coating foam with fiber glass is genius! I knew i could count on you guys :)

Gixxerfool, I'm so glad you're as excited as I am! Unfortunately, as I am just starting out i don't have any access to either a mill or a lathe and as much as I would want to get my hands on one to mess around, i have no experience with one. I have heard of the greatness of delrin, but unfortunately i dont have the means to work with it properly.

I get that. I got lucky and my friend had one. More of just an example. They have a lot there. I needed an acrylic tube. They had it. Delrin is nice but if you don't have a way to machine it, it could get ugly. Can't wait to see what you do. For sounds you could get a sound chip from replica props. It can be triggered by a simple switch on Closure.
 
Some Progress shots i took today. Kinda dove straight into it. I grabbed 2 foot long pipes of 2" 3" and 4" abs and welded them together in the muzzle configuration.

Still need the top piece on the main body to finish off the core of this build. The stock I made out of maple wood (which was the stupidest thing i have ever done. It took me so damn long to saw through all that and twice as long to sand it all down.) It is pretty cool because the maple tree is native to the Boston area, so that made me happy at least. All in all this whole build has probably taken me 7 hours in total so far. I bought everything new so the price was a bit high at around $70 in materials. Still needs a LOT of work and even more clean up, but I'm satisfied with the progress i have made. Let me know your thoughts!,

Project Update! I'm still going! I've been pretty busy otherwise so its slow progress. But still progress! Finished fiber glassing it to shape. I took Floral foam and carved out the top of the canister. Then i covered it in packing tape and fiberglassed it on. It took around 3 coats of fiber glass and many many days of getting those damn shards out of my arms. IMG_3977.JPG
Then i painted it with a sandable grey primer. It wasn't all the way filled so i took some spackle and filled in the rest. Painted that grey as well.

Then came the trigger. This was fun to figure out. The trigger itself is a piece of aluminum that i bent over a bench vice. Then i sanded down the end to a point and drilled a hole through it. The part that connects to the main chamber is just a uniball pen cap around a screw. Inside is a spring that is compressed when the trigger is pulled and shoots out when released. I had to sand down a nut until it could fit inside the pen cap but keep the spring in place.

So for the future what I'm looking toward is finishing all the major components in the gun itself. Then overlays probably made of craft foam. And finally the last little bits, the wires, the pipes and tubing and figuring out the electronics to make this thing whistle like a train.
 
My friends, after many many months of work. I'd say this project is 99.99% finished. Now no it isn't a perfect replica. But for my very first project and introduction into prop making, I like to think i did a pretty okay job. Im sure this thing is RIDDLED with apprentice marks, but I do hope you enjoy it for what it is. At least a little! Thanks for staying interested :D1.jpg2.jpgIMG_2573.jpg4.jpg6.jpg5.jpg
 
Very cool build, I like the aging quite a bit. I am almost done my Anti-Materiel Rifle, Needs a scope but Fallout builds are always fun, since most things that are in game are built after that war and It makes mistakes seem intended haha.

That looks awesome! Yeah fallout builds give you some wiggle room when it comes to messing up. Cracks/bumps/rips look natural and intended most of the time. anything post apocalyptic seems like a good first build.
