Wes, you can adjust zero on that meter with the screw at the bottom of the meter face. Turn one way or the other to bring the needle to zero, then back the screw off slightly. The screw has an offset pin that moves a fork back and forth. When properly adjusted, the pin should not be in contact with the fork.
@lwilton is ready to start a band instrument repair instrument repair channel.
Puts me in mind of using my smoke generator to find vacuum leaks in the car.
Greatly enjoy your channel. So interesting and you do an excellent job keeping it interesting. Your craftsmanship is impressive.
As a bari player, I approve (greatly!) of your dent repair music!
Great work 😊
I didn't know that such a measuring device existed-very cool-thanks!
Great to see the Bach tested and repaired!
Pure magic to watch.
Nice work, thanks
Great video, thanks! I haven’t been able to find many other videos on using mag machines with instruments on KZhead and the techs at the shop I’m apprenticing at don’t use them. So this video was very helpful for me to see/understand the process of using one! I assume the process would be the same with clarinets, you would just plug up the open tone holes as well as the end of the joint?
Great stuff!
Those gauges when not in the jasmith cabinet have multi ports. One side pressure, other vac. You can look for vac as zero or the level of vacuum. I’ve used one on reproducing player piano to set levels.
Very cool.
I haven't heard of this machine yet
"The "Magnehelic Machine". This was a short one. Wes did not have time to explain how it works. It seems to use water in some form yet, No droplets of water were seen on the table!? (the jazz background music was New and a nice touch)
looks like a vacuum pump
inches of water is a unit of measurement (temp and verticals dialled in) - its a much lesser scale (higher in sensitivity) to the more common inches of mercury vacuum scale. 😊😊😊 - happy horn blowing - or whatever u play!!
👍👍👍
Nicecwork
I have a King 4B trombone with F-attachment that sounds like it Donald Duck when I play it. The F-attachment section has been replaced after the original was severely damaged. I don't have a magnehelic instrument, but I've checked it for leaks by pressurizing it under water. I've also pushed a bore scope through most of it to see if there is any kind of blockage and if the rotor is lined up properly. It seems to check out okay. Any suggestions?

Hey Wes, what do you use for lubrication while you are burnishing?
Super Lube. We are switching all our lubes to non petroleum food grade, have been really liking.
