is this compressor repairable?

[tpolley]

a friend gave me an oooold compressor this evening. it had a couple fittings broken off. one was in the output of the pump. he got that out. the piece that threaded into the tank is still stuck. he tried to remove it but i think in addition to the male piece still stuck inside, the threads are shot. if you look at the first picture you can see about 1/4 inch of material still stuck. below that, the threads look to be pretty much trashed.

here are my ideas so far. drill the hole out to the next biggest size and tap it. or buy some sort of threaded fitting and weld it over the hole. i don't know if i'm good enough for an air tight weld.

also, what the hell is this chamber-looking thing? is it some sort of compression chamber to catch any vaporous oil that escapes from the pump? it was broken off at the pump output. the material was removed and the threads on the pump side are not damaged. a new fitting can be bought and the chamber thing can be re-installed.

the copper line that comes off of the chamber threads into the base of the pressure switch thingy (which was broken off) via a flared connection. forgive my amateur termilology.

here's a serial number plate off the motor if anyone can decypher a date.

so what do y'all think? is it worth my time or should i set it by the curb and hope it's gone in the morning?

Definately worth repairing. I've had luck removing dutchmans in the past, but if worst comes to worst, simply drill with the appropriate drill and use a tap to clean out the threads. If it were my project, I'd install a new check valve and get rid of the mobile meth lab experiment on the outlet of the compressor head.

Might have been a state of the art aftercooler. Or not...........
I'd save it,in fact I could use one about that size at my cabin on the Mississippi.

I agree, new threads are much better way to go than welding. Make sure you use the same size or at least a common pipe thread size if you go bigger on your fittings.

The NPT tap for the next size bigger than that is going to be very expensive if the OP doesn't have one. I would cape what is left of the ****** out then verify if in fact the female threads are damaged. If they are, he can go to a pipe supply house and get a thread-o-let in the appropriate size and weld it on.

Is that 1/3 or one third horsepower? Waste of time with it unless you need a portable that will barely pump up tires.

I think I'd want that tank hydro'd before I'd use it.

Looks like a tank explosion waiting to happen. Same the pump, replace the tank or have it checked.

Probably would be ok just don't run it up to a high pressure (tank life). My old man has a compressor from the 60s that he keeps out at his storage building. Just runs it long enough to get 50-60psi in it for filling tires on the cars in there.

if you want save the tank, take it to an auto repair shop let them take a good look inside with bore scope. rust buildup can be deceiving from outside.
