Our latest DIY project-a screen coating stand.

Okay, then I take it that it is rigid (except for the spring loading holding the screen).
If the top is slanted closer to the wall how to you manage to terminate the stroke at the top without having emulsion run down when you tip the scoop coater back?
Don't mean to be a wet mooseman blanket here, but I think I'd have a problem using something like that having emulsion running all over the place after the up stroke. You have given me some ideas though as I tend to set the screen on a trash can and the screen has occasionally slid.
Maybe in addition to having the springs hold the screen, a handle at the top allowing movement to lean the top away from the wall when terminating the stroke.
Maybe I'm really missing something.

When I coat screens they are tilted against a wall with the top being closer to the wall also. No problems with emulsion dripping. I do use two hands on the coater. Maybe an inch or two from the top I just roll the coater back and then finish up. All in one fluid motion on the stroke. If that makes sense.

Wayne, it works like an auto coater in that sense.
Check out this video and see how they do it. This is basically what two handed guys do.

Well, you got me thinking. That's a good thing.
Maybe when I have the time, I'll crank out the mig welder and build something like this. Unit with a handle to lean in and lean out, rotate the screen from top to bottom for second coat, then rotate again, orient inside to outside and do the final coat. I'll have to figure a clamp method on the screen tho.
I'm sure it works for you. I believe my screens are quite a bit smaller than yours (21 x 23) which allows a different design since I only need 1 hand for the coater.
It's at the bottom of my list right now, lol.
Update - watched that video and it gave me an idea for the missing part - a way to clamp the screen in. The coater is a unique design. Mine would be running out the sides I think at the end of the stroke tipping back. It's still at the bottom of the list :)
Gilligan:
M&R's uses a more standard coater but the method is essentially the same thing. Probably less "delay" between stopping and rocking it back. I just wanted you to see the mechanics... timing wise would obviously be adjusted as you are doing it by hand.
I have a few spring loaded ideas on how you could flip the screens around, not sure how good they are though. I don't have the room to test them out anyway. :)
If I did, I'd probably get Grunig. :)
