Sorry for the double post but went shopping today.
The bad news is the home depot I went to didn't have any pressure rated fittings bigger than 1.5 inch.
The good news is they had the 1 inch rainbird CP-100's. So I picked up two of them and a basic tap/die set. I also got 10 feet of 1 inch and ten feet of 1.5 inch sch 40 pressure rated pvc pipe.
This pic is the basic layout for two over under guns without the tubes in order from barrel to chamber.
1 inch barrel(not in pic)
1 inch screw in fitting
1 inch rain bird cp-100 valve
1 inch screw in elbow
1 inch tube(not in pic)
1 inch to 1.5 inch adapter inside a 1.5 inch elbow
1.5 inch chamber(not in pic)
1.5 inch end cap.
I'm not familiar with the screw in fittings and would like to be sure they are good to use. I took some pics as close as I could.
The barrel 1 inch screw in fitting on the output of the valve.
The 1 inch screw in elbow fitting on the input of the valve.
( it looks like it has a crack in it but it is just a shadow from the flash)
After all this..the biggest tap is not big enough for the pressure gauge threads so I'll have to go back and get some adapters. I also plan to pick up some mod parts for the cp-100's so i can use them blowgun actuated instead of electric.
I'm not set on two guns...just got two sets because the 1inch valves are hard to get here. Ideas for one gun with two valves are very welcome
