threading

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

you would have to be very very very skilled, but yes you could. how do you think they do it for plumming parts?

They mold it like that. The mold has threads in it.

What he siad. imigine it like makeing a lego. i guess. the plastiqe. enters the mold and is cooled.

Ever watch the show how its made? its interesting.

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?

if the chamber fan inside dies i have no way of replacing it

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.

sandman · Tue May 08, 2007 7:34 pm

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

they shoudl last well over 100 shots. according to my knowledge.

sandman · Tue May 08, 2007 7:41 pm

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
