Is there a formula for how high a longarm machine should be and the correct angle for the handlebars? My husband keeps wanting to adjust it and I told him I would ask ya'll if there is a way to know.

it should be adjusted for your height, what is comfortable for you when you are using it...hands, elbows, shoulders need to be in a natural position or you will be aching and having a hard time quickly, it has to be the right height/angle for you personally

As ckcowl said, it has to be comfortable for you. And, that may take a few times adjusting until you get the right feel. You may think it feels good and after working with it for a little bit, you might have to adjust it again.

These answers are exactly correct. When my HQ18 Avante arrived and the guy put it together, he had me come stand near it and put my hands on the machine. He asked if that was comfortable and if I wanted it higher or lower. The proper height is one that is not straining to YOU. I find that I end up feeling back pain after pinning (so considering a zipper or red snappers), but running the machine it's the perfect height. Adjust it with you standing as if you would be running the machine.

I purchased a hydraulic lift so when I'm working at the back of the machine, the handles will be at an elevated height. When I working at the front of the machine, I lower the table. Your elbows should be at a right angle for long term use comfort.

in a perfect world i am sooo jealous you lucky girl :lol:
