Hey! In this instructable I will show you how to make cheap powerful and very fun to use air rifle.
It is super easy to make out of items from your local hardware shop. :)
For this you will need:
- BIKE PUMP
- PVC PIPE FOR BARREL
- S SHAPE CONNECTOR
- INNER TUBES VALVE
- PUMPS PIPE
- PLUMBING VALVE
- PIECE OF WOOD Other items required:
Step 1: WATCH VIDEO!
To save you some time I made step by step video on how to make this air rifle. so please watch video first if you prefer it insted of reading steps. You will also see my air rifle in action. If you cant see video, find it on my youtube channel - DIY ZE
After watching video proceed to step 2
First put some hot glue on the rim of the bottle, then glue a plumbing valve on. Next seal it all with hot glue to make sure it is air tight. When glue is set, secure all tightly with electric tape. Next poke a hole at the bottom of the bottle wide enough to push in bike inner tube valve it. When that is done put a good amount of hot glue around it to prevent air to come out of the bottle.
Next thing to do is take your S shaped connector tube (mine is 15 mm diameter) and stick it onto plumbing valve. Secure it on with some electrical tape. Plumbing valve will be a trigger.
Take a piece of wood (like in shown in pictures or video above) and cut out a piece like shown, to be size of your bike pump. Next place pump into a gap you just cut out, and secure it with cable ties.
So far so good. Now take your air bottle and attach it to other side of wood (like shown in pictures or video above) using some cable ties. Next secure all cable ties so they dont slip with some electric tape.
Assemble all! take a bike pump hose/tube and attach it to the valve, the other end pump like show. Take a pvc pipe (barrel) and atach it on top using folded cardboard so you can slide barrel when loading. I used 15 mm diameter pipe and and S shaped connector. Gently secure pipe with more electric tape over cardboard, but not too tight as barrel needs to move freely back and forth to be able to load your rifle with darts. Darts can be made out of a rolled cone shaped paper and nail or screw. Or you can find berries that fit and shoot with them.
Now the moment of truth. Pull barrel back to be able to load dart, put dart into a barrel and move it back to meet the connector. Close plumbing valve/trigger and pump the air bottle up till you cant no more. Its more fun if you compress air as much as you can for most powerful shot. Aim and open valve/trigger to release all of the compressed air into a barrel and drive your dart with incredible power. My darts go through plywood. :)
