Getting Back in the Saddle

Hey guys, it's been a while. I still lurk semi frequently but university has been eating up my time the past couple years. The only exposure to launching stuff recently was at "potato launcher day" or something similar at campus, where some guy with a ball valve pneub gun tried to outshoot a solenoid sprinkler pneub gun. It was nice to see but...disappointing. Fast forward to later in the year when my friends and I manage to gather up ~300 stray golf balls from near a driving range and can't figure out anything cool to do with them. Me - "Oh I should make a golf ball gun." Everyone else - "Yeah that would be awesome!" Never happened because I don't have anywhere that sells the right pipe for the job. Fast forward again to last week, where I went home for the weekend and found the holy grail in a scrapyard: a length of 1.5" SDR 21! Went home, scrounged parts of old guns, brought them back to school.
So today we had an awesome shoot with a fully functional golf ball gun! No big deal or anything, a pretty small chamber and just a sprinkler valve, but WOW golf balls are perfect projectiles. I pressurized the gun to 120 psi behind a concrete BBQ pit just in case the pipe wasn't fully safe, but now I feel perfectly safe shooting at 90ish. My friends and I spent a good hour or so lobbing golf balls into the surrounding fields, then headed back. Nostalgia brought me to the Hybrid Cannon Showcase. A recent mental image reminded me that a local hardware store is closing.
Orchard Supply Hardware is being bought up all over the place by Lowe's, and as such, the deals are pretty great. I remembered hearing about this and went over there tonight. Walking up, the sign on the front said they would be in business for 3 more days. Inside, pretty much everything was gone, but I made my way to where all of us feel at home: the pipe and fittings section, PVC on one side and steel/iron/brass on the other. What kind of discount did they have, you ask? Oh, nothing too big, just NINETY PERCENT OFF all fittings! Aaaand now I have the beginnings of another hybrid $50-60 worth of galvanized fittings for a whopping $1.74. The cashier must've done something wrong, I dunno. Not complaining!
I don't have any tools with me here, or any of my precious spare fittings, valves, and igniters, but over winter break I really want to get this thing put together, configured for burst discs first, then hopefully a piston valve later once I have time for tinkering.
This ended up a lot longer than I wanted it to, but oh well. I'm hyped!
