The barrel is 11 inches, The piston is in the 1/2" brass steel nipple, The chamber is 10", The piston is a crayola marker with epoxy in it with a neoprene sealing face, The valve is a 1/4" ball valve. If I am missing something tell me and I will tell you.

Thanks for the positive feed back!

If you want more power and all you have is a crappy bike pump, try using propane, i think it has about 200psi in it at the right conditions.

I am debating.. Should I use my 60$ to make a high pressure pump, Or buy a 2 gallon compressor? What would you do if you had to choose?

I agree. Buy as much compressor as you can afford, you won't be sorry. The little units run hot and typically have a short life span. They are designed for road side emergencies and the occasion beach ball blow up.
