I shoot with only air in s. california

Post by dudevato »

I did have the water/air rockets as a kid. They were great fun! After seeing U Tube videos of Potatoe and pool ball bazookas, using hair spray to fire them with, I put together a PVC (plastic pipe) golfball bazooka using compressed air.

Originally the barrel was 4 feet with like 6 feet of 2" PVC used as the air chamber. I use 80 psi and a 1/4 turn ball valve. The golf ball shoots up untill you begin to loose site of it.

I then made up some pvc rockets, some 12" long that were capped, front and rear. At the center of the 'rear cap' I drilled a hole and inserted a 1/2" wood dowle, some 12" long. At the end if it I glued on 4 popsiscle stick 'fins'

It fit just a bit loose inside the barrel, so I wrapped the 'front cap' like 2 or 3 times with electrical tape to seal in the presure,

I've increased the length of the barrel a few times and the air charge capacity kept getting larger and larger.

At some point I shot a measured distance of 1,220 feet, using a 45* launch angle.

I then modified the gun again to its present form. It now has a 20 foot barrel fed from an air chamber of 50 feet of 2" PVC pipe/T's & elbows.

At this point I'm going to see how far it goes 'downrange' I'm sure thinking 'an easy 1/4 mile.

Soon I'll be checking out 'straight up shots'

This is where I'll be asking and learning from you members about parachute fabrication and deployment.

This is going to be a pretty cool hobby to learn from.

That's amazing! That long barrel should be awesome to build the velocity. Have you ever thought of building a "Pumpkin Chunkin'" launcher? That contest looks really interesting!
