I should add to that on my digital manometer has a place to hook up rubber lines to hook up probes to Check intake (J hook) and exhaust (straight) probes too. Checking airspeed has taught me more than anything and I couldn’t do it till I built this bench. I bought two extra probes as I have a handheld digital manometer and I’m going to see if I can calibrate it so the friend that bought my bench could further his education. I also bought an automatic depression control that when I changed my lift it would automatically go to 28 inches. I bought it probably six years ago and never wired it in. Probably never will. Bruce offered to buy it back from me. Lol. He’s working on a nice panel now and is going to make me one. For the Facebook guys he on there.
