I was wondering if a normal machine shop could thread the inside of a reducer bushing to accept a cleanout plug?

I think you would first have to solvent weld a piece of SCH 40 or SCH 80 inside of the bushing before the threads were cut, to insure that they were deep enough.

Why would you want to thread a reducer bushing? Just buy one that's already threaded. http://www.mcmaster.com for "PVC reducer bushing".

it is pressure rated ABS that i am working with, and i cant find any threaded reducing bushing in 3" x 2", so that i can but a plug in it.

My only other option is to seal the chamber with a cap and hope that nothing goes wrong inside.

Why would anything go wrong with a cap?

O ythis is going to be a combustion. i woulda known that but you didnt say so now i get it.

EDIT: you probably could replace it by sawin near it takeing the fan out replacing it and fixing with a coupling.

oh, lol, i guess i didnt

um, well as it looks like that i will have to go with the cap, how long do chamber fans last?

if anyone has any other suggestions i am open to them

Edit: interesting, i didnt think about that, lol
lol, i was trying to think about how to make a fan that can fit down the barrel if it needs replaced, lol

well, now thinking about what i got, i think i will put 2 small fans in the chamber, if one dies, i will have the other

and if both die i will get a coupler
