  1. I use an HP Combi tank, and have yet to spill a drop. There are some

    rubber washers that have to be in place, and the lid needs to be

    pressed down all the way around.

     

    <p>

     

    I get nice even skies, repeatable development, easy (for me) to use.

    Fill/empty time is about 45 seconds, which isnt bed for half a gallon

    of liquid. Just include it in the overall processing time.

     

    Since when I shoot film I use Grafmatic magazines, the six-shot

    capacity of the tank is a perfect match for the Grafmatic.

  2. When you shop for a lab make sure to tell them you are talking about

    4x5 film. Not all of them do, even though their ads say that they

    process "professional" film (that usually means 120)

  3. Another thing you might try is a screw extractor that you can find in

    tool shops. It is made like a tap, but the twist is in the unscrewing

    direction. Get a tap holder for it, and find one that fits snugly in

    the 1/4" hole. It has a series of ridges that grab the sides of the

    hole and hopefully unscrew the stuck piece.

     

    <p>

     

    They may have glued that thing in there. In that case you're just

    going to have to wrestle with it.

  4. My Calumet Cadet came with a reducer in the 3/8 tripod block. It has

    two slots in the edge for a spanner wrench or a wide flat blade screw

    driver. Does yours? If so, sacrifice a screwdriver and carefully file

    or grind it until it fits EXACTLY. Clamp in a vise and try to keep the

    screwdriver from slipping because the reducer is probably soft brass

    and will burr up easily if it slips.

     

    <p>

     

    The alternative if you have a drill press is to mount the block and

    use a drill that is bigger than the 1/4 threads but smaller than the

    3/8 threads and drill it out. A friend with a small machine shop could

    help here.

     

    <p>

     

    I modified my Berlebach by drilling out the 3/8 stud and making a

    loose mounting bolt that drops down inside the head. It was a project

    though. It involved some lathe work.

  5. Just a thought, but make sure you have the right side of the film

    packet facing the lens. This is the side with the cross hair in the

    circle. Otherwise, the outer envelope will pull all the way off when

    you pull it to expose the negative.

     

    <p>

     

    If you look at the end of the envelope nearest the metal end clip you

    will a see a raised white strip of cardboard. This catches inside the

    end of the holder and keeps the envelope from coming apart.

     

    <p>

     

    You do all the loading and exposing with the lever in the L position.

    Only move it to P when you are ready to process.

     

    <p>

     

    The suggestion to blow a film and take it all apart is a good one.

    Hold the metal clip with your fingers and pull the twin tabs at the

    other end until it separates. You can also see how the release catch

    operates in the holder.

     

    <p>

     

    Feel free to e-mail for more detailed info. I shoot almost exclusively

    Polaroid 4x5 and 8x10 and have very few mishaps any more, although I

    did go through a learning period.

  6. Most of the time I use 4 jaw chuck in the lathe and check for size

    often. I think that a GOOD quality hole saw (Starret, etc -- not a

    cheap import) that is close to but not larger than the required size

    would give the cleanest result in the wood board.

     

    <p>

     

    This is a round tube with saw teeth on one end that mounts in an

    adapter with a pilot drill. Put the whole works in the drill press,

    center up the board, clamp it firmly and cut slowly.

     

    <p>

     

    Dont use the version that has a number of different rings in a slotted

    base. They are flimsy and wont work cleanly.

  7. Unless there was a change, I thought that Pan X referred to Panatomic

    X, the fine grain film that was rated about 32 ASA. Plus X is a ASA

    125 film. I think they quit making Panatomic some time ago, which may

    be the reason for the cold storage.

     

    <p>

     

    I would guess that if you give it good exposure for the shadows and

    test a couple of rolls to get the development for the highlights, you

    ought to be OK.

  8. Seiko's are decent shutters. They are the Japanese copy of the Compurs

    and Syncro-Compurs. They are well made and not that bad to work on.

    Any repairman that knows Compurs likely also knows Seiko's or will be

    able to find his way around one with no trouble.

  9. I have to go with static too. What you are seeing, if this is indeed

    what's happening, is a record of little lightning bursts across the

    surface of your film. Dry conditions (winter weather, heated dry

    rooms, etc) are the prime causes. You know how you get a spark off the

    end of your finger when you touch the refrigerator door after

    shuffling across the carpet? Same idea. You can see the spark clearly

    in a dark room; so can the film.

  10. Both are just boxes to keep the light side outside and the film side

    inside. As long as the bellows are tight and everything works, get the

    one that feels best and concentrate on equipping it with a complement

    of the best glass you can afford.

     

    <p>

     

    That said, I used the Graphic View II all through the Navy, and found

    the same rig after I got out. It is a bit more limited in its

    movements, but I never found anything I couldn't do with it.

     

    <p>

     

    The Calumet is a good machine too. I have never used it but I believe

    there are folks here who have.

  11. I cant tell you much about the fancy plexiglass models, other than

    they are all supposed to a good job, but cost most of your monthly

    income.

     

    <p>

     

    I still get by very nicely with an old Kodak tray Siphon. I have done

    dye tests to see just how completely it flushes a tray full of water,

    and it is a very efficient -- and economical -- device, although they

    may be hard to find.

     

    <p>

     

    As long as you dont crowd the tray, and remember to shuffle the prints

    around and from top to bottom every few minutes it will wash to

    archival standards.

  12. I have been going with the direct from the thick concentrate approach

    for years with good consistent results at 1:31 also. I use a small

    medicine cup that is marked at 1/2 oz and 1 oz. Just right for either

    1 pint or 1 quart tanks. I add about half the water and use the rest

    to rinse the cup thoroughly to get it all dissolved.

  13. It's been a while since I fired one of those off, but I would be

    willing to bet the numbers refer to milliseconds of delay. 0 for X

    sync, and different delays for different flashbulb types. (A common

    setting was about 20 ms)

  14. If you can get it on a lens board and have enough bellows to focus you

    can use just about anything on a Speed Graphic, because it has the

    back shutter. The bellows draw is about 12 1/4" so that places a limit

    on how long a lens you can use.

     

    <p>

     

    The only catch is that you will have to readjust or install a proper

    cam for the rangefinder depending on which make you have.

  15. I have'nt used the Ilford, but it is a good film. As for filters,

    about all I can tell you is that it will lighten its own color and

    darken its complementary, so a yellow would lighten yellow and

    yellow-orange and darken blue. I have taken to using a #23 light green

    for a lot of my foliage stuff. It keeps the bluish shadows much more

    open than a yellow, but I dont have any bright colored flowers in them

    so I cant say for sure.

  16. First you might make some contact prints (4x5 you said?) They will be

    big enough to evaluate your lighting, just in case. From there you

    should know if it is processing or your enlarger. If it is bad

    processing you should probably look at your agitation technique. I use

    the HP Combi tank and a gentle once-over inversion every minute -- my

    skies and even-toned subjects come out nice and smooth. If it seems to

    be the enlarger, check that your condensers are installed properly. If

    that checks out, check the alignment to make sure everything is

    parallel. As far as the lens goes, if it is a decent make of the right

    focal length for 4x5 (135-150mm or so) Then I'm not sure what to tell

    you.

  17. 1: I prefer the Alden. It uses a rotating light trap so nothing

    touches the film if you have it loaded correctly. I have used the

    Lloyd's, but after a period of use, it would build up grit in the felt

    light trap and scratch. Drove me nuts figuring out what was going on.

     

    <p>

     

    2: I use a stainless tank and reels. I hold the center of the reel

    between my thumb and finger and let it revolve as I pull off the film.

    Clean and easy and no hassle.

     

    <p>

     

    3: Photoflo or similar, and follow the other gentleman's suggestions

    regarding sponges, etc.

  18. I believe there are parts sources listed at www.graflex.org. If your

    septums are bent a little, I used a flat feeler gauge stock about the

    same thickness as film, and did some gentle un-bending and hammering

    flat. The feeler gauge placed under the lip kept it from getting

    crushed.

  19. The dense roll sounds like it was drastically overexposed -- probably

    the result of a wrong light meter setting since the other roll sounds

    like it is fine. The blurring is halation, where the light has spread

    through the film base and fogged. A little halation can cause specular

    highlights to take on a sort of glow that makes an interesting effect,

    but generally it is avoided if possible by proper exposure and

    development.
