Ok, so now I'm deeper into my project of "converting " my old WABCO circuit breaker into a traditional shop compressor. ........ here's my sticking point.....
Need help!
First option for me was to buy a 2 1/4" drill bit- figure out how to adapt it to a hand dtill, then dtill out the THICK welded In plate on the side of the tank, then run my 2"NPT tap in, and , WALAH!!! Screw in my 2" x 3/4" bu g adaptor!!! Sounds easy, but NOT!!!!
Ono my Second option....
The air circuit breaker had this huge , and heavy, brass bolt on adaptor, that when u bolted leaves me a 2 bolt flange to the side of the tank, and male threaded end, which would need adapting.... BUT! here lies the issue........
The "pipe" is 3.5" diameter on the threads, at 14 TPI, which is NOT COMMON, and I can't even find a reducer for it to me a 2" NPT x 3/4" bung!
Any and all help would be AWESOME! !!!
I'm stuck with where to go.......... not really wanting to weld onto the tank, as I like the "threaded" option for future u see. .....
And don't trust any welders around me to be able 5o safely weld it in, without making a bomb in my garage......
If I could just identify WHAT thread pipe reducer I need, I'd be set, but 6 hours of research led me know where!!! It's the 14 TPI, that throws everything off!!!!
Standard pipe being 8 TPI...... PLEASE HELP!!!
do you think I could safely re-thread the 3" 14TPI to 3" npt 8 TPI, with alt of thread tape, and o ly running g 150 psi, versus the 300 psi the sir-break tank is rated for, or would "re-tapping" brass threads just be an invite for trouble!?!?!
