Ding (and Tom),

I'm using 24" (60cm) fluorescent tubes and full sheets of watercolour paper. I'd recommend 'building' a box using 6 36" (90cm) tubes - I suffer from slight light falloff printing to 24" but 18" prints are fine. Construction is a doddle - just buy narrow fluorescent tube light fittings and make a box with the tubes at the bottom and put a sheet of 6mm glass over the top of the box about 12" from the tubes. Neg/paper lie on the glass face down, cover with a sheet of plexiglass and about 6kg of books spread over the top to give good contact. It works.

Obscure photo-gadgetry??? I'm looking for a Goerz Tenax 8x14 roll film camera in good condition (preferably with Dagor lens) - is that the sort of thing I might find?

Avec plaisir Tom! 
Btw, If you're into collecting or simply looking for some old obscure photo gadgetry, You can time your coming with the Bièvres International Photo Fair, it's one of the biggest and longest running photo fair happening in Europe  http://foirephoto-bievre.com/index.php?lang=en  It's near my place. How's that for a double excuse to visit Paris.  heheheheh.. 

Regarding my setup, im sure the uv bank of tubes would give me a better work scenario.  Only trouble is i have 8 other Osram bulbs on reserve because i read somewhere that the lifespan of this lights are not as long as other options
(1000 hrs?). Also the prospect of figuring out wirings, ballasts, carpentry, etc., is not very enticing to my 'plug and play' sensibilities. :-) Cheers, Ding

Ding,

your system is worth a trip to Paris and having a look :-)

However for whole sheets a bank of UV tubes makes probably more sense.

Tom
