No need here for photos Bill, but thanks for the offer. I've seen photos of a couple of moving backer systems and I have Ratigans book. One was a drum type paper holder that rotated continously, the other a big flat paper clamp that cycled back and forth. Nobby Uno told me of one that used to be in Clearwater that was a single strip of butchers paper. They had a roll at one end of the target frames and an electric winder at the other end. They pulled out the whole strip, hooked it on and let it wind up ever so slow. Wouldn't work for us, we get howling southeasters at about 1/3 of our shoots.
I like the idea of mechanical moving backers but the KISS principle is the best though.
The stationary backer is the simplest system and to correct the problem Bill spoke of, why couldn't you have a manually sliding tray that holds the backer. Have a 11"x17" backer, start close to it's bottom, at each target change move it down 1.5" or so. Have preset holes drilled into the side of the slider frame. Pull out the pin, reset the pin to the next level & drop down the backer on its frame.
The mechanism part to make it move isn't a problem, it's whether or not the 5 shots are displayed clear enough and I think the NBRSA through Calvin says it is ok.
Any critique of a stationary/slider system is welcome.
Cheers
