Gene,
Here's a possible workaround to part of the rollfilm back question --
I used this with a 120 camera I built that has an integral rollholder,
but it could apply to a removable back too. Conley made a series of
cameras called the Folding Kewpies about 80 years ago, and these had
little 'carriages', for lack of a better term, to hold the film rolls,
which allowed them to avoid the problem and expense of spring-loaded pins
or whatever to hold the spools in place. They're made of black-painted
sheet brass, with spring tensioners, and work well in the camera I made.
They also allow the body of the rollfilm holder to be somewhat smaller
than it would be, since it doesn't have to be much taller than a 120
spool. All you need is a square compartment the carriages can fit into.
Being a collector on the side I won't suggest anybody go out and
canabalize a No.2 Folding Kewpie. They're not worth much or that
important historically, but they're not that easy to find either. But if
you're handy working metal these carriages shouldn't be too hard to make.
There are only two parts, the frame and the tensioner. All you need
besides is a winding key that can be pulled out of the body of the
holder, as in most old box cameras.
If anyone is interested, write to me off-list and I can make a little PDF
with a photo of the Conley roll "carriage". I've already got measured
drawings.
Off the topic, thanks for the further info on the corner splines. I've
been worrying about dropping the camera with the half-lap joints and
having it pop apart. Besides making the box sturdier I think it would
look better with them.
