so you've mounted your PH's on the inside.....I've been using 35mm slide holders for pretty much the same thing. what diameter is your "composing" washer? This was something I was thinking of trying.

Andy, I have had good luck in finding "real" backs, that 8x10 cost me like $7 US, it is metal and has two thumbscrews that allow me to flip it to vertical or horizontal composition. At the front I installed a filter ring that allows me to use filter on it. Focal length is 90mm, no real vignetting. Here is the back alone: http://members.home.com/penate/camera/back.JPG Here is the back sans GG: http://members.home.com/penate/camera/backback.JPG See the square in the middle, it is a flat magnet. I mount a small washer that I use as my "composing" lens and then I mount the pinhole (non-magnetic) and keep it in place by putting a big (magnetic) washer on top. Since I needed to have easy access I removed the GG and mounted it to a cardboard frame, I also mounted a plastic fresnel reading lens on the GG, that helps me have a brighter image: http://members.home.com/penate/camera/fresnel.JPG Here are couple of pictures showing the front of the camera and the filter ring, you can also see the "composing" aperture (AKA washer): http://members.home.com/penate/camera/front.JPG http://members.home.com/penate/camera/filter.JPG I also have a very nice 5x7 metal back I bought for $10! at a photo fair (some vendors have no idea what they are selling!! I am not complaining though!). I have yet to turn it into a pinhole camera.
