Wagon-Mounted Constant Air Pressure Blaster
Posted: Fri Jan 02, 2015 11:26 pm
Hey Ya'll,
I've been planning on making a CAP gun for some time, finally went shopping this afternoon. I bought everything but the pipe for the reservoirs and the air lines. Its going to be pretty big so, as the name states, I'm going to mount it into a wagon.
Here's some basic info:
The capacity will be 4.5- 6 gallons (depends on how tall I want to make it).
The air capacity will be either 5 or 7 gallons at 120 psi.
I'm using four 3+ foot lengths of 3" PVC (in parallel) for the reservoir.
The nozzle is a handheld gun (much like the one on the SuperCAP) with 6 ft. of 1-1/2 in. braided vinyl tubing coming off the rest of the unit.
The end of the gun is threaded so different nozzles can be used (thinking about using a shower head for a riot blast type output).
I may mount it in a plywood box for protection (accidental tip-overs, vandalism).
Now I have a question for those with experience. My Lowes carries few 3" fittings, pressure or otherwise. I found some 3" to 1-1/2" ABS fittings on clearance (the only ones of their kind in the store). I know that the only difference between pressure and non-pressure PVC FITTINGS is the size of the glue surface, but can ABS FITTINGS be used for pressure (less than 150 psi)?
Cool? Yes! Impractical? Maybe...
