like to get rid of. These are 10x10 units with 39 argon lamps in each. Each
lamp is individually switched. Anyone interested?

To put it more accurately, people reading this newsgroup *might* be
interested, but it's against the rules here. BFD.

I got one of these guys several years ago cheap because
the owner had broken the upper glass in transit to a photo
sale. I've never used it, there is no longer any paper slow
enough. These were made originally for printing 10x10 aerial
camera negs on slow contact paper like Azo. The lamps not
only switch individually but in groups of ring shapes to
compensate for the fall off from some wide angle aerial
lenses. The civilian version has a nice stainless steel
mask. I am afraid they are now boat anchors.

like a charm.
The lamps are arranged with separate switches for each
lamp for dodging but the lamps are also arranged with
additional switches that turn them on or off in concentric
rings. The 10x10 printer has 39 low wattage GE UV lamps.
They are no longer made but can be found. The printer also
has two "nite lite" white light lamps and four neon safe
light lamps.
They are beautifully designed and very ruggedly built
machines but paper suitable for contact printing on them is
simply not available any more (although I understand someone
may have undertaken to make a replacement for Azo).
I suppose one could replace the neon lamps with very low
power incandescent lamps and use a couple of sheets of ND
filter material on the diffuser to get the thing to work
with enlarging paper. They are too beautiful to throw away.

UV. Most paper has brighteners in it which glow from the UV.
I guess _that_ could also be used as a source. In another
post I made just now, but before reading this, I suggest
replacing the UV lamps with very small nite-lite lamps.
Using ND filters or tissue would then be a practical option.
One can get suitable ND filter material from Roscoe in
large sheets that are not too expensive. It may even be
possible to get material suitable for making variable
contrast filters.
The very nice masking arrangement and ability to dodge by
throwing switches would be handy for LF printing. I may have
a shot at this for my printer.

These are rather nice for platinum printing.

I am surprized they are intense enough. Platinum printing
usually requires a very strong source such as a plate burner
or not too strong daylight, similar to printing out paper.
The UV sources in the Morse printer are about 4 watts each.
They were designed for short printing time on paper like
Azo, not for printing out papers. Have you actually used a
Morse printer for Platinum?

I took a printing class with George Tice in the early 1990s, and on
the last day he brought his platinum printing setup in and demonstrated
it. From the description of the arrangement of light sources in the
10x10 Morse I am pretty much certain that that's what he used (his printer
was 10x10 as well). I don't know whether he modified the light source
somehow for more brightness -- were these bulbs available in higher wattages?
The printer was very convenient and certainly nicer than other light
sources for platinum printing that I've used since.
Platinum emulsion is very UV sensitive. Perhaps that makes the
difference.

RJM
prints on normal enlarging paper by using an enlarging timer to control
exposure. I have a timer that will do time increments of 0.1 seconds.
With all of the bulbs exposing I can usually get properly exposed
prints at times of about 0.4-0.5 seconds. When I cut the number of
bulbs down I can get a little more exposure latitude. If we added an
ND filter for 3-4 stops density decrease, and also used the timer we
would probably have a reasonable amount of print control.

to contact paper this sounds about right. The argon lamps
turn on and off instantaneously, one could not make shuch
short exposures with incandescent lamps.
Its quite possible that a ND filter would also work, one
would want to know its UV transmission. The problem is that
you would not be able to vary the contrast of variable
contrast paper.
I will have to experiment with this when I print next.

I have not been feeling much like darkroom work (no A/C).

July 4, 2006, from Lloyd Erlick,
Last summer I decided against getting an air
conditioner.
This year I've learned from my silliness and
put the smallest one they sell in my window.
What a relief. As Canadians say, it's not the
heat, it's the humidity ...
regards,

And what about Azo ? I haven't heard anything from Michael Smith since
that APB for the Azo ordering he did with Kodak a couple of years ago.

2 - 5 minutes. The heat build up during the exposure time was minimal.
I also printed to blue print paper.
If I had one of these things now, I would print some of my old negatives
to a home made silver chloride coated paper.

I am very surprized that you got this result. My
experience with printing out paper is that it requires a few
minutes in direct sunlight. The intensity of my Morse
printer is very much below this. They were intended for
printing aerial camera negatives on rather slow contact
paper, something like Azo, with a few seconds exposure time.
The lamps are very low power Argon lamps. BTW, I found a
bunch of the lamps at a ham radio swap meet a couple of
months ago for a dollar each! I don't think the guy selling
them knew what they were.

indicate the relative intensity of the Argon lamps vs. sunlight: insert
a negative in a print frame in front of a sheet of enlarging paper (any
type for this test). Place in direct sunlight for a few minutes and
check the image on the paper. Do the same with the Argon lamps in front
of the negative. You may be surprised.
I have also used B&W paper loaded in a press camera and exposed the
paper until I got a good visible image on the paper (only a few hours at
f8). The printed out images can be fixed in regular fixer. Last
emulsion that I tried (Kodabromide F5) worked ok but the image lacked
contrast. I did not try intensifying or toning the images.
The paper negatives produced using a camera contact printed out ok (must
use a paper with out a water mark.

I find rarities often go for a song: people looking for
the thing are rarer than the thing itself.
I have a job selling a huge collection of antique
medical quack devices. When the right buyer can
be found some of the items go for $20,000. As an
experiment I tested the waters on ebay and it looks
like the collection would go for ~0.05 on the dollar.
Collectors know this and there is sniping and collusion
aplenty. At any one time there are 10-20 active well
healed collectors and they all know each other.
It is going to take longer to sell the collection off
[at sane prices] than it took to collect it.

"Well-healed collectors"? One hopes they don't become re-injured ...

images from sunlight on conventional printing paper. They are not
strong but appear. it will be simple enough to try it with the
printer.
I wonder if we are talking about two different kinds of printers. I
don't know if Morse ever made plate burners but what you describe
sounds like it might be one.

I tested with a sheet of enlarging paper placed on the inner
diffusing glass with some opaque cardboard under half of it.
I gave it ten minutes. The exposed end was quite purple. I
didn't use the top glass plate because it is not original on
my printer and has significant UV absorption. I presume the
original plate was clear glass rather than green glass with
much greater UV transmission. The attenuation of UV on mine
is probably actually an advantage since exposure time is
very short.
Previous experiments with photolytic printing using
ordinary developing out paper suggest that the Morse printer
_would_ probably print POP in a few minutes. POP is still
made by Kentmere in England and sold in the US under the
Centenial POP name. For those not familar with POP it is
printed directly in sunlight. The image is not permanent
unless treated in toner and fixed. The original image color
is a sort of purplish brown but it can be toned to many
colors.

they were designed for printing aerial film. They were
intended for printing on very slow contact paper and even
for that have exposure times on the order of a few seconds.
Morse also made a larger version of this printer.
You can inflate the pressure pad with a bicycle tire
pump but be careful because it doesn't take much air to get
it right.
