On the Marshmallow cannon, about 2 hours. On the T shirt launcher, a couple days working off and on in my spare time.

I think and engine cylinder hone may work on larger pipe. 
Min-2"
Max-7"
Engine Cylinder Hone
On small pipes a brake cylinder hone may work.
Min-11/16"
Max-1"
Brake cylinder hone
Edit: This brake hone has a larger capacity
Min-1 3/16"
Max-2 3/4"
Larger brake cylinder hone

A brake hone works well.. After the wall of the pipe seam is removed. You either need a quick way to make it small or if very lucky, find a pipe with a really small ridge to begin with.

What about a sanding drum on a Dremel? Too inprecise?
