I wanna make my own pipe, but i'm not sure what to buy to make it, my friend made one out of brass (I think) very cheaply a long time ago and it hits nicely, I was thinking of using this to start out..[ame=http://www.amazon.com/Anderson-Metals-38300-0640-Brass-Nipple/dp/B000BO79EU]Amazon.com: Anderson Metals #38300-0640 3/8x4 Brass Nipple: Home Improvement[/ame]
I don't know what your blueprints are but you could probably go to your hardware store and find something just like that so you don't have to wait for a tiny little pipe. If you even were thinking about buying it from that link.
