 From what info I've been getting any pipe will work. Just remember the heavier the pipe the stronger there geared motor has to be that is turning it. 
Ideally I was getting that a semi truck exhaust pipe would be best, on that thought since BIGFORD is the only trucker I know in my reach I'm going to ask him if he has any old exhaust pipe around him. might get lucky.
