I've been at this a while now, and with the help of many of the forum members, I think I've finished it up. Gaze upon its wonder:



Looks pretty stock from the outside. The internal conversion was quite simple. Remove a bit of hardware and you get a nice film chamber. From there it's just a supply-side spool holder, and a takeup-side film advance mechanism. Oh, and a frame counting window.



I used a hanging folder tab for the red window, we'll see if that works out. For the advance, I used a key from an old Kodak folder, and a bolt with a spring for tension. One of the main problems with these cameras is the massive amounts of light they leak. Hopefully I've taken care of that with a full-body foam. I also isolated the takeup chamber with cardboard, since that seems to be where the majority of light comes in.

I may do a bit more work, including film transport guides and perhaps a 6x9 mask, as it takes 6x10 frames right now.

Results to come in the week ahead...

If you should have a problem with film flatness. Check out the conversion I did on Kodak 3A, on my blog. Helps keep more light off the film too.

I figured if I have a problem with flatness, I can install rails as you did. I'm pretty sure my homemade pressure plate should do the job, however.

When you install a mask for 6x9 (and rails -- they *will* help, by preventing the film from curling tube-wise between the pin rollers, regardless of the pressure plate) you'll need to move the frame counting hole.  And at that point, if you haven't already done so, you might also want to make a mask for the viewfinder to show the actual film-captured area -- preferably to be mounted on the moving glass that performs the parallax correction.
