So, I went to the store today to start buying parts for the pneumatic launcher that I am building. I am copying the design for the TBL1000X2, on the Low Powered launchers page. What I am using is a 1.5" elbow into a 1.5" - 1" threaded reducer into a 1" nipple into the sprinkler valve into another nipple into a the female reducers into the 3" chamber. After purchasing all of these, I had to go to a differant store to buy my sprinkler valves. I couldn't find rainbirds, so I setteled on 1" water masters. And to my dismay, the 1" nipple wouldn't fit into the 1" sprinkler valve. WTF! Now do I have to buy new fittings, and if so what, or can I get sprinkler valves that my 1" nipples will fit into?
Thanks for any help!!:)
