You may be interested in a simple modification of the Gravity Works frames
that turned those lemons into useful print frames with pressure advantage
very similar to vacuum frames, without the noise. (Even if the rubber band
doesn't take your eye out, the tension it provides is only one degree better
than overcooked oatmeal). The laminated wooden frames, however, are
excellent and firm. I got rid of the rubber thing and its pins. I cut four
sheets of 1/4" grade A ply so that each half could sit above the hinged
frame allowing space for the hinging to remain functional. 1/4" bolts with
wing nuts and washers secure the plywood places firmly; the bolts go through
the original frame to the plywood that holds the hinged back in place. (The
hinged back, as you may recall, is about an inch thick and sits well above
the frame). In use, this is not as convenient as a spring-backed printing
frame but the pressure is quite uniform and superior to most printing
frames, and worth the moment or two of extra time - and I can still peek
under the hinged section. I wouldn't rush out to buy the GW frames, but if
you have them then this modification will give a very tight
negative-substrate contact. From the dung heap they have become my favorite
frames. (BTW, I also put in a better grade and slightly thicker sheet of
glass) Joachim

I realize that alt printers LIKE doing things the hard way, but I keep
thinking maybe someone is listening --
Over the course of the years I've had 5 or 6 different makes & styles of
contact frames, and tried several more -- NEVER did one of them work
really comfortably, including even the Great Basin frame I had custom
made. For one thing, to make large prints and leave a bit of paper border
it had to be so huge a little old lady could hardly wrassle it. For
another, it was such a production to make a few little tests, it made me
cut down on the testing, which is what's REALLY crucial...
Of course Gravity Works gets the prize for worst -- if that rubber thing
hits you in the eye, you've got a hospital bill... beautiful antique
frames are good as frames, but softer than a baby's tusch in contact, etc.
etc. etc.
What is ALWAYS good, or good for me, available anywhere and no shipping
charge or customs, is two sheets of plate glass -- the print sandwich gets
sandwiched between them. Tape or glue the edge of one sheet so a piece
sticks out for lifting, and you have no hassle perfect contact one size
fits all, no springs, no pinched fingers, and you can let the paper hang
out anywhere you want. True you can't so easily check progress, but...
IF YOU'VE MADE YOUR 21-STEP TESTS, YOU CHECK THEM FOR EXPOSURE in the
first place -- they're much better indicators anyway, because they've
already been developed, washed, dried, and aged (oxidized) so give a much
better reading of what an exposure becomes in the print.
Or simply tape the negative to the paper -- if you really MUST check in
progress.
Of course nobody will be impressed with your custom made sheet of
glass...and it *is* easy... But just in case, the list ran a couple of
threads on the topic years back, & there's an article showing a couple of
setups in Post-Factory #6 ("Light Carpentry"). But forget the very
expensive "water white" glass, Starphire if memory serves. My tests showed
it was no better, maybe worse. Regular demi-plate costs $20/sheet for
extra large, about $5-$10 for average.
