This is my plan so far anything missing.
ALL THE NIPPLES MUST BE GALVINIZED STEEL
Use a regulator. Obviously a PPS Stab is the highest quality, will give the least deviation and least chance of reg failure (can be catastrophic in PVC launcher. And to Make sure I test the reg before using it to air up your launcher Dual regs are better.
To Use sch 40 or 80 PVC, 80 preferrably, and not the foam core stuff.And to Make absolutely sure your pipe is solid core. Sch 20 PVC or foamcore will not even hold up to the low psi you'll be running at. Also make sure your pipe is free of any manufacturing defects, and use primer and cement properly when bonding pipe and fittings.
But at the very least, make sure all your parts are rated to about 300psi (metal parts only under pressure), reg it to about 250 with a pop off valve around 275.. and air would be best (comes pre-reged, extra safety measure.. an lp HPA tank is even better), if you use CO2, you'll want to run it through two regs and with the pop off valve.

Use a burst disk/pop off valve. This can be done by simply inserting a 150psi burst disk (availiable at most hardware stores near the air tools and compressors) into a tapped 1/8" NPT hole, preferrably going through 2 layers of PVC (PVC pipe and a fitting). Do not use a burst disk/pop off valve rated for higher than 150psi! The whole idea of this is that if a reg fails or the pipe otherwise comes to a point where it would overpressurize, this burst disk will vent the pressure before the pipe does violently. Make sure and place this somewhere away from your body when in firing position, don't hit yourself in the head with the air if it goes
where can i put this in my diagram am completly new and dont wannt hurt my self anything will be aperciate if u help just so u know i want constant air and it to be a mortar

...And Saint Attila raised the sprinkler valve up on high, saying, "O Lord, bless this Thy sprinkler valve that with it Thou mayest blow Thine enemies to tiny bits, in Thy mercy." And the Lord spake, saying, "First shalt thou remove thy solenoid and epoxy the pilot hole, then remove the guide rod, then thread your pilot valve directly to the body of thy sprinkler, lest thou increase thy pilot volume by a single iota, then lobbest thou thy nerfs towards thy foe, who being naughty in my sight, shall procedeth to the gates of reinsertion."
