This tutorial is not going to be super, but it will be good enough that you can make the project yourself.
If you are like me, you are probably trying to make guns all the time. In this DIY, I will show you how to make a pellet gun that shoots 1/4 inch pellets for a sling shot. I built this gun two weeks ago so please comment ideas because it is not nearly done yet.
Also this is my first instruct able, so please be understanding. That doesn't mean I don't have anything to offer.
This gun is pretty powerful, I am estimating considering other guns and pellet gun I have fired (I don't have a chrono) about 550-650 fps at 250 psi. I know most of us can't get 250 psi but I can from a nitrogen tank. Using a bike pump to 160 is fine, maybe just a bit slower.
This gun can produce about 16 fpe and the pellets are 16.8 grain I believe.
Step 1: Designing the wood
So to get started, look at the first image I showed. You will need to cut out a stock design from a 1 inch wide piece of wood. About 2.5 feet long. Paint it any color you like as I painted mine brown. Make sure it is kind of like mine so the pipe fits right.
Step 2: Buying the parts
You will need besides the wood:
A half inch metal ball valve (not plastic) with threaded sides
A 2 inch piece of 1/2 inch PVC pipe
2 half inch slip PVC elbows
Another piece of half inch pipe(about 3 inches but it depends on your wood stock
A 1/2 inch threaded to 3/4 inch slip PVC piece
a tire shrader valve cut from an old bicyle tire and the rubber has been removed with a knife or sand paper
A metal arrow that is hollow
A 1/2 inch threaded to 1/2 inch slip PVC piece
JB Weld or JB Kwik
Creativity. You can't make it just like mine so you must be creative,
