threading

[sandman]

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

[hi]

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

[iPaintball]

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?

[sandman]

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

[pyromaniac]

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]

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

[pyromaniac]

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

[sandman]

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

Whoo hoo i just filled my help someone out assighnment today.

one mroe question why did you buy presure rated abs?

[sandman]

well, its not bought but im going to get it on friday or saturday, and i needed to know what all i needed

and i got it because it is the only thing that i will trust next to my face, except steel.
