The buffer tank can be pressurized by small tubing, but you need large tubing from the buffer tank to the barrel.

This. Keep in mind that smaller tubing will restrict flow, so while your air compressor can be connected using standard 1/8" tubing, everything between the tank and the cannon should be 1". Consequently, you're probably not going to want to use a standard air tank like you might find on AndyMark, look for one with 1" ports (or 1/2" ports and use several of them to merge to a 1", since 1" port air tanks are really hard to find).
