This is a a great begginer project for someone who wants to build a pneumatic potato gun. pricing is reasonable, being around $50- $60. took me only an hour to build. The only thing that i would change is the handle, it shold be bigger to hold more air. I havnt found the range yet because I am not sure how much pressure it will take. I dont want pieces of pvc stuck in myself!
read final page for legal.
ps. sorry about photos, my camera is broken so I have to use a phone.
