Air Rifle Stock Help

Unread postAuthor: lava98 » Mon Jul 21, 2014 4:34 am

Hey guys,
I'm currently planning to make a QEV pneumatic spud gun that fits an air rifle stock.
These are the stocks I'm looking at: http://www.gamousa.com/family.aspx?familyID=68
(BTW: I know that I could create my own stock, but I am simply terrible at woodworking)

I have several questions before attempting this build:
1. Which of these stocks would best fit a spud gun?
2. What adjustments would this stocks require to fit a 1/2 inch QEV, blowgun pilot, and a 1/2 inch barrel?
3. What could I do to fit a chamber into the gun? (I was thinking about using a separate chamber in the butt of the stock that is attached to the QEV by tubing)
4. How would I hold all the components in place in the stock? (Epoxy perhaps?)

Also, if more compatible stocks are found, please feel free to recommend any.

Thank you!
I'll be sure to post my build once I get started.

Hmmm...Buy a plastic blow molded stock for twice the cost of wood and still have to mod it or start with three pieces of 2X4 and build your own???...?

I think it's really a question of style because the mods will all be custom to you're liking, there for all pretty much the same mods.

I thought about it, and decided that I am going to make my own stock. However, the design i had in mind requires a lot of interior cavities for parts such as the QEV and chamber. I believe that this would be extremely difficult to carve out of a block of wood. Any recommendations?

(Also, it would be awesome if you guys could point me to an easy method of creating a gun stock :D )

hey mate if you make the stock out of multiple layers then you can use a router and a straight fluted bit to cut out space saves you messing up with a chisel . Buy untreated/stained wood because treated will never cut like you want it to (personal experience) if you try to not penetrate all the way through the outer boards then it will look clean.

The best way I know of is to get the gun you have and like the best and lay it on paper and trace around it, that's the profile. Then use a different paper and stand the gun up on it's stock and trace around the butt, there's the end view.

Glue and clamp the 2X4s together over night, then transfer the tracings to the wood and follow the tracings. For the cavities use a drill to do most of it and just clean up and square off the cut outs with the chisels.

Tech Tip: Sharpen your chisels very sharp and use them like knives, no need for hammering. :bigsmurf:

I highly recommend carving a stock out of a block of wood. Just make sure you're not using the lowest quality wood. Don't repeat my mistake of putting a lot of work into a wooden stock and then have the wood deteriorate after a few years ;)

The best way of carving out the cavities would be with a router. If you don't have one, you can drill holes along the outline of the cavity and then pry the excess out with a screwdriver and finish it with a chisel.

Don't place the components on the wood and trace the outline with a pencil because this method always results in a sloppy fit. Take your QEV, chamber, barrel and other components and measure their dimensions, then draw them in 1:1 on some drafting paper making sure you have all the spacings correct. Cut out the whole outline of your components from the drafting paper and then transfer it to the wood.

I've made a detailed build log of my latest project over at the Airgun Universe forum. Maybe you'll get some ideas from it http://www.airgununiverse.net/community/index.php/topic,638.0.html . Just beware there are a lot of pictures to load and some have unfortunately been resized back to their original resolution for some unknown reason.

Muhaha, I actually have an idea on how to help. This one requires a small trip to YouTube, and into the world of gun smithing, midway USA is a channel on YouTube, they show the processes to making your own stock from a blank ( block of wood with grain running the right way) they also show tips on other aspects of gun mechanism mods as well as stock maintenance. I feel that everyone on this website should check out some of their videos to help with stocks and some mechanism adjustments.
Edit:if you need to carve something out such as for you mechanisms drill through the blank and cut out a rectangle then chisel from there. Also there is nothing wrong with pins holding the mechanisms to the stock.
