Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
I have always coated with one hand, the screen held by my other hand. With a little practice anyone can do it that way. No matter how it is done always be consistent. After two and a half decades I think I finally got the hang of it.That's how I was taught, really fast and clean on 23x31's, BUT, that's a big a z z z z scoop coater on those mamuth screens there though, wow!!! Nicely done!!
I am sure that many have mastered the one arm method but I just don't believe that evenness and consistency can compare with two. This what I have. The lower arm is supported hydraulically and can fit a large variety of frame sizes without adjustment.
A correction to my earlier post, it is "starry night pinholes" not "starlight" Just because you can't coat one handed is no reason to say your two handed method is better.
