Almost threw out a Jaco vintage style gauge until I watched this video. Super easy to adjust. It's wild that a 50+ year old mechanism is still in use today.
Everyone got that. Pinch "U" shaped part together for higher reading or spread "U" apart for lower reading until accurate . Or is it the other way around because there is a video by sixtyfiveford where he pinches the "U" to lower the pressure ? I just bought a Pit Posse dial gauge and it's 3 pounds too low compared to my master digital .
I bought a VDO gauge in 1970? and it reads 6lbs low. No screws on the back to take it apart. Any suggestions? I can't remember why I didn't return it?? It was such a disappointment I've never used it.
My issue is the needle is pointing to 16 psi at rest. Need to move it back to zero so I don’t need to subtract every time. I’m haven’t figured out how to move it to zero
Carefully pry the pointer off, set it in the correct position, gently tap it back down onto the shaft. You can probably find a cheap watch hand puller to safely lift it off. 40 years in oil and gas industry calibrating and adjusting meters and gauges. Bending gauge linkage is not the correct way to adjust.
Welcome back! I didn't realize how easy it was to calibrate the old pressure gauges.
Glad to see you back. Always enjoy your content.

What is the make and model? I'm sick of these new ones not working or only lasting a couple of months.
Fantastic tutorial, thank you!

@@daltonthomas901 It’s probably a pry-off bezel. I’d try it by hand first…
We have the same thing, mine is over 3 psi so I need to spread the U thing a little bit. Thanks for the info 👍🙂
Miss your content. Will you be back???
Awe. Thanks man. And yes sir. Working on a video right now. The Atomic S/MC.

mine is at 16 lbs too,...?
I have that work in my hose
This isn't calibration, it's only adjustment, as you don't know the true reading
