This is my finished derringer bb gun. it is powered by a cap from a normal cap gun and is meant to shoot at small targets. It was my first experience with creating any type of functioning trigger mechanism and it ended up working very well. The trigger along with the hammer and sear were cut out of about 1/4” oak. The power source is a spring that sits behind the hammer. To make the barrel I used an old bb gun barrel, a modified rivet, and some steel tubing. I took part of a rivet and filed it down and heated it to fit snuggly inside the bb gun barrel. The rivet works as the nipple to place the cap on. It is the same concept of a percussion cap gun. I then found some spacers to fit around the barrel that also fit snugly inside the steel tubing. I then added a little bit of JB weld, and the barrel was complete. For the pistol stock I Glued two piece of oak together and cut out my pattern. I then re-sawed the piece to be about 3/4” thick for a comfortable grip. I used my homemade spindle sander to round the edges and it worked out great! To hollow out the area for the trigger mechanism, I used my drill press and drilled holes in a line, then filed out and used a dremel tool to do the rest. Instead of using nuts and bolts for the trigger and hammer, I used a metal dowel that fits snugly so that nothing sticks out of the side of the grip. I also chiseled an area for the barrel to sit in instead of having it places on top of the stock. Let me know what you think!

Like it. Was making rubber band guns for a while. Now on cigar box guitars. May have to try one of these.

that’s really creative- the design process in action!

I love the fact that you are using handtools and the home made spindle sander, too. Would like to see pictures of that in action!
