How to build the Airspud. Does not include interchangeable barrels. |
12" of 3" Sched. 40 Pipe |
36" of 1.5" Sched. 40 Pipe (Not for golfballs) |
(ONE) 3" End cap |
(ONE) 3" Coupling |
(ONE) 3" x 1.5" Reducer Bushing |
(ONE) 1.5" PVC ball valve |
(ONE) Tire valve |
PVC cement |
This gun is safer but still has a great risk. |
Step one: Drill .5" hole in end cap for tire valve. |
Step two: Cut 4" off the 36" of 1.5" pipe. You now have a 4" and 32" piece of pipe. |
Step three: Sand all parts to be glued |
Step four: Wash pipe in soapy water or prime it. Which ever you care to do. |
Step five: Pull tire valve through hole in end cap |
Step six: Glue end cap on one end of 3" pipe |
Step seven: Glue 3" coupling to the other end of 3" pipe |
Step eight: Glue 3" x 1.5" reducer bushing into 3" coupling |
Step nine: Glue 4" piece of 1.5" pipe into 3" x 1.5" reducer bushing |
Step ten: Glue ball valve onto 4" piece of 1.5" pipe |
Step eleven: Glue 32" piece of 1.5" pipe into ball valve |
My second potato gun, the "Airspud", is
complete. I had it explode once but it was easily repaired. I put about 80
PSI on the newly dried glue and it gave way. So I glued it back together and
let it sit, thus causing a small leak. Next time I make one this big I will
be generous with the glue and let it dry overnight.
There are several great features to the "Airspud". It is much safer and more reliable than the "Tater2000". You can easily determine how far an object will go with the "Airspud". You cannot do that with the "Tater2000" because it uses an uncontrolled explosion, not a set amount of compressed air. You do not have to rely on a spark or chain reaction with the "Airspud". There are no sparks needed. The "Airspud" is safer than the "Tater2000" because the user knows the exact amount of pressure the air exerts on the walls of the PVC. With the "Tater2000", you have no idea what kind of pressure those explosions are exerting. The "Airspud" reduces the probability of your chamber exploding and killing you.

PSI | Velocity (m\s) ±5% | DPA=15 | DPA=30 | DPA=45 | DPA=60 | DPA=75 | Projectile |
20 | 21 | 23 | 39 | 45 | 23 | 23 | Golf Ball |
40 | 44 | 99 | 171 | 198 | 99 | 99 | Golf Ball |
100 | 100 | 510 | 884 | 1020 | 510 | 510 | Golf Ball |
These calculations neglect air
resistance. To reach these distances projectile must be shot with a strong
wind.
(DPA=xx) - Distance Per Angle {45 would be the furthest if air resistance was non-existent} Not Exact (±5%) The overall average cost of the "Airspud" is $40.00. Status: Golf Ball Launcher (No longer own) |
