The only way to slow it way down would be to re-gear the drive. Adjusting the motor drive signal will not be slow enough. Then the problem is film speed as it transits the tanks to the next roller...

I have been repairing, updating, and using X-Ray film processors for 45 years now. I have used them with mixed results in photography. The problem is four fold.
1. the developer used in the...
now that our windy season is dieing down, I plan on do some foot work around the Anastazi ruins here in NM. I restored a 1948 Trail King motor scooter ( way before the Tote-Gote) used to prospect...
Cool Beans! I love the very light weight and fast set up. No pan nor tilt,but 99% of all press cameras were ever tilted either and the photos went world wide and are famous to this day.
I have...
Now it time to play with my X-Ray film for correct exposure and development times.
My old tractor, 2 seconds F:45, Microdol-X for 12 minutes agitation 5 seconds every 60 seconds.

The winds have died down. I loaded up some Fuji X-Ray film and did a shot of a cactus in my yard. I wanted to check for light leaks and the lens depth of field. The closest the lens will focus with...
That is really cool! I plan to really use my camera if this darn wind ever stops.
I'm a retired X-Ray Engineer. I have worked with film for the last 45 years and all X-Ray film is made for a mechanical film processor or even the old dip-tanks. For 99% of the film the developer is...
Part 8:
The final part that needs to be made is the wooden Cut Film Holder spring back plate.
All this does is to apply a force on the CFH to keep it in place and light tight. It must allow you to...
Part 7:
Now that I have my ducks in a row for the tripping of the shutter, I have made the linkage to trip the shutter and allow the lens trip lever to return. As it turned out after hours of tring...
Part 6:
Now for the hardest part. The shutter tripper. As stated above the Fuji and Nikon lenses are so east to do I'm not going into it.
The Rodenstock lens is the exception. It has a long throw...
Part 5:
The range finder is glued into place once you have verified the lens zero. The two nubs on top of the frame provide a good lateral support of the wood block. They are spaced far enough apart...
As stated above,it the back of the camera can be converted to a flat surface by wood fillers I see why none off them could not be converted.
If the camera has the Zeiss range finder your pretty much...
Part 4:
Once you have glued the Range Finder in place you can now mount the cut film holder back. The two vertical stanchions are now set and will support the cut film holder ( CFH ) frame.
The...
Part 3:
The wooden pivot block is glued in place. JB Weld is used.

While the block is setting up the Range finder is prepared. The wood block is just thick enough to have the view port...
Part 2:
Remove the Range finder. It is held in place by flat head screws that can be reached by a small flat bladed screwdriver. There is one rivet that is part of the lever system that must be...
Part 1:
I decided to convert a Polaroid 250 camera to 4x5 cut film for no other reason than weight. Where I live everything is uphill, both ways. While many have done the 100 series of Polaroid...
I just retired and it too was a project I wanted to do. I live at 7,000 feet ASL and lugging 40 pounds of camera equipment is just not macho anymore but I still want to take photos using a 4x5...
I have just converted a Polaroid 250 to 4x5 making it a very light weight field camera. Is there any interest on how I did it?
Very fine detail under the overhead cover. Well done.
Thank you for the info.
At what guessamation was the ASA? Nice images.
At 1:3 you will need 15-19 min developing time @ 68 Degrees F. Agitation every 30 seconds. If 1:1, you will need 7-9 minutes. Same agitation, open tray.
In a container be careful. X-Ray film will...
Very nice Tuco.
O.K, it's a little different than most other sites. I will do that,thanks.
I've been a mamber for more than a month now. I cannot respond to a for sale posting of a lens I want. A pop up window say I do not have the proper permission.

Which version of Interflon Food Lube are you using? Where did you buy it?
Paint the walls semi-gloss white. The semi-gloss will not hold dust like flat paint will. A DARKROOM, is just that,dark. A good safe light 5 feet above your working surface will illuminate the whole...
Years ago you could buy a template for exposing paper to the negative that looked like a pie-chart. It had different segments of separate densities that allowed a certain amount of light through...
Yes, X-ray film was used as a "paper" and a normal enlarger was used with a negative. You get a positive image. I've done this many times.
No it is the whole negative. I cut it from a much larger film,the edge on the right is a little off plumb for being cut in the dark.
It is the way the cut silver emulsion is cut and the edge is open...
100:1,wow. When you say gas burst, are you timing nitrogen burst?
With no replies, I have tried 7 and 9 minutes so far with good results. I may play with extended development as well.
I repaired a C.P Goerz Apocomat Atar 6" lens in a Rapax shutter and tried the x-ray film today at a close up. 2X magnification F:9 @2 seconds,no filter.

Getting back to my subject, I disassembled and cleaned four shutters. I used brake cleaner and industrial Q-Tips and lens paper followed by oil free compressed air out of a Air Brush at 15 PSI.
I...
I will be using it for close up work. I bought it as salvage 35 years ago so nothing lost if it does not work well. The self cocking shutter is a plus.
The Snap ring is a good idea if I cannot find the proper securing ring.
I need the lens securing ( mounting ) ring for this Alphex shutter lens. Do any of you know where I may be able to find the ring for this lens?
Thank you.

And to my colleges in the 'Down Under". May the light of 2018 expose your films at Zone 3 every time you trip the shutter!
Thank you for the tip. It makes sense.
