    Phototherm 4x5 made from Patterson reels

    I have recently seen two eBay auctions of Phototherm units with 4x5 inserts that were made out of Patterson reels.

    One currently listed is here: http://www.ebay.com/itm/PHOTO-THERM-...99344643062561

    Look at the eighth picture.

    The one which recently closed, and I did not win, was for a broken unit. Here: http://cgi.ebay.com/ws/eBayISAPI.dll...vip=true&rt=nc

    Look at the third picture, the unit on the left.

    Has anyone ever seen one of these 4x5 inserts? Got any pictures? Can you make one at home out of things laying around?

    Michael:

    Are you sure these weren't actually put together by Phototherm themselves?

    They may well be. But they aren't like the ones Phototherm has now. And the ones Phototherm has now cost a fortune.

    What I want is a chance to examine one of these up close and personal. Or at least get a good set of pictures.

    I've tried to scheme a way to make a 4x5 holder as well as a 5x7 holder using Patterson reels as the ends of a cage. But I've never been successful. So I really want to know what this looks like. Especially if it works.

    The 4x5 insert that is with the one I use looks nothing like that pattersonstein. Dunno.

    Neither does mine. Which is exactly why I want information about the Pattersonstein.

    The current holder is next to impossible to duplicate except in mass production.

    Morgan's MOD processor is pretty good, but it could never hold the sheets in for rotary use.

    But I must have 40 Patterson reels that have found their way to me over the years. Most are just collecting dust.

    I'd be interested in this too. I have one of the Phototherm ones (Ouch!), and thought about DIYing something with patterson reels too. Will look at the pics and see if i can help. Has anyone contacted Phototherm about this? Maybe they made them back in the day before doing their current version...

    Here's another crazy idea... how about taking the rotation spindle for a Phototherm, (the piece that looks like this: http://www.phototherm.com/interctr/pvw2.gif ) and somehow fitting it to the guts of a Nikor 4x5 tank? What is the diameter of the hole in the middle of the nikor 4x5 reel? I wonder if the phototherm spindle could be made smaller diameter (it seems like it's a little wide, from just eyeballing the pictures). That might allow 12 sheets of 4x5 per run of the phototherm, assuming chemical coverage was high enough... ?

    You couldn't rotate 12 sheets. They wouldn't stay in the reel. Too much dynamic drag on the film edge.

    The Nikor reel comes with a metal band to keep them all in place. Or are you saying there would be so much drag it would collapse the sheets and let them pull out along the edges and get all crinkled in together in the cage?

    How about taking a Patterson reel, cutting the the central post and gluing in an extender? I'm sure you already thought of this and rejected it for some obvious reason I am just to thick to have seen.
