This is my first homemade. Mofo stands for Machine operated functioning... object (needed a last O in there) It's a simplistic pump gun with a large airtank. The tank is made from two inch pvc and a U bend. The valve is a ball valve I'm borrowing from my friend for now, but I have a solinoid valve that I need some batteries for. The pump can be a bike pump or a ball pump. The range isn't great... yet. Once I fix up this small leak, and hook up the sprinkler valve, it should be getting some nice range. The coolest thing is that it also doubles as a super soaker!
I'll get some pictures up tomorrow, when my friend comes over.
