Anyone else into paintball? I first started playing 20 years ago, and took a break for close to 8 years while various surgeries healed. A couple months ago, a bunch of friends all had birthdays within a 2 week span and decided to celebrate with slinging paint at each other. So we made it happen a couple weeks ago. I broke out my two most prized possessions from my playing days, and spent a month replacing every seal and o-ring in the things. I also had to jury rig a charger, bench build a battery pack (with some advice from @Skysoldier ) get a compressed air tank hydrostatic tested, rewire a solenoid, install braided hoses, and found out that one of these paintball markers I got for the sum total of about $20 is one of only 10 made like it, and one collector has 8/10 and desperately wants mine. I tuned the blue/black one pretty well and am firing off about 14 balls a second.
