morse contact printers
 
I'm clearing out my shelves and I found three Morse contact printers I'd
like to get rid of. These are 10x10 units with 39 argon lamps in each. Each
lamp is individually switched. Anyone interested?

No one on this newsgroup would be interested.
People on the rec.photo.marketplace area might well be 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.

Doesn't sound like a boat anchor...sounds cool, other than the
unpleasantry of having to source and pay for replacement argon lamps,
but the detail of circular placement and switches is something that
would be a pain to implement.

How about contact print internegs onto graphic arts film...that's slow,
right?

To slow it down for faster paper, one could always add neutral density
filtration between the lamps and the top glass. Simply putting cut sheets of
tissue or even bond paper below the glass will work.

If its as slow as contact printing paper it should work
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.

N.D. filters may work, provided they are effective for
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?
