If you plan on making the chamber with the same size pipe, mak it as long as the barrel. You really should use larger pipe though.

what pressure d you plane to take it to?

i would say about 15 inches would be good at 100 psi.

Are you planning on regulating CO2? If so, you need a regulator specifically made for use with CO2.

Well, regulators from air tools have a pressure limit of about 200 psi, so you can't use one to regulate CO2. You would have to buy a beverage or paintball reg.
