I'm not exactly what this qualifies as in relation to the forum, or even if it is relevant at all.

Recently I ran into a video buy the Slingshot Channel that demonstrated a "slingshot crossbow" of sorts. The concept was simple, and the design was intended for easy construction. So I went ahead and built myself a "slingshot crossbow" that I am calling the Blundershot (not exactly sure why) :lol: , but credit for the design goes to Joerg Sprave as I only modified it mildly to suite my materials and aesthetic concern.

Since I had some red oak on hand, I went with making a nice solid build rather than something put together of scrap wood. The parts that are not oak are what will be painted flat black.

Here I have the thing assembled. The components have been rough cut with only minor sanding.

The way it works is the ball is put into the pouch of the sling shot, then slid between the two "fingers" of the locking mech which is held closed by the trigger piece. When the trigger is pullled, the fingers open to release the pouch and the ball is let loose. After successful test shooting with the rough assembly, I went ahead and finished each part for a final construction.

And the final result.

Power isn't anything to talk about. It'll go through cans and shatter glass. It's just one of those fun projects. Fun to build, fun to shoot.

(Again, sorry if this is misplaced)

Beautifully put together, kudos! I particularly like the contrast between the painted and unpainted parts, nice touch :)

JSR, you'll be happy to know that the fork was put together with an epoxy casting method :D

Well built and good craftsmanship!

Always happy to see such well planed out designs. Great attention on ergonomics on the stock ;)

9 out of 10 in my book. (10's reserved only for MY work lol)

Well the initial design was not my own. In fact I believe the person to whom it belongs is a member of this forum under the name JoergS.

But I thank you for the positive comment. :)

*Edit: But I did design the stock.

Thank you :)

I plan on making a video response to his video on how to make essentially this same thing.

With the craftsmanship you've shown on your cobra cannons, I wouldn't hesitate to say that it would be easy for you. Just don't completely make mine look like trash :lol: .

Looks good, is any of the gun made from plywood like Joergs. Im considering cutting one from a pine 2x6 to shoot arrows. The fork will not be a traditional design. Basically a bolt through the front. Do you think it will have enough support. Thanks

Clemsonguy1125, I made the stock from plywood. Since building this I have made a version with an internalized lock that is integrated into a plywood stock. The majority of this build is red oak.

I'm not sure I can picture what your describing correctly. You want the fork to be made from a bolt?

Yes, on this version I have made the functioning parts from oak. On my recent version, The parts are oak, delrin, and aluminum. I see how you plan on doing it.

Wood has a very high dimensional stability. My oak "barrel" on this one is 3/4" x 2", but that was just because I didn't want to rip it down out of laziness. You would be fine with a 3/4" x 1 1/4" "barrel", maybe even only an inch.

Thanks, I think the weakest part will be where I cut the hole in the middle of the wood for he trigger mech. I may put a pair of mending brackets over the wood around it.
