12" 200psi Antique Brass Pressure Gauge Repair
While searching ebay for a larger pressure gauge for my mig gas regulator, I came across this antique 12" 200psi all brass ashcroft pressure gauge. $186 later it's out in my shop and I decided to repair it tonight.
Someone had cut the inlet fitting off the back so I drilled it as deep as I dare with a 7/16" bit and tapped it 1/4"npt. I started the threads with a standard tap and finished with one that I've ground to make a bottoming tap.
The male qc is only in there for testing, I'll replace it later with a push lock fitting. The pics are fairly high res so if you want a closer look, click/click/zoom (hold alt key and roll the mouse wheel forward)
After I finish the interior of my shop this spring, I'll install this gauge on the wall and plumb it into my airlines. I can't decide whether to restore the faceplate and polish the housing or just leave it like it is. What would you do ?
