    Hmmm? They must make chamois leather different ways when they split it. The Kodak chamois is pretty smooth and has a velvet-like feel to it . . . not at all rough textured.

    I look forward to tearing into the 4C tomorrow, but it will be in the afternoon as I will be taking my Mom and a couple of her HS classmates (class of '44) out for breakfast at a small town cafe up in the far remote reaches of the county, then drive them around through the mountains and valleys for a couple of hours. This is a ritual that I perform for Mom and her buddies about once every month to 6 weeks, as they can't get around to visit each other like they used to.

    Anyhoo, as soon as I get to tearing into that camera I will come back with a report on my success or failure as a Panoram tech. I'll be thinking all along on how to fix the bellows, but that isn't an immediate concern, rather the swing lens mechanism is the first order of business.

    This may not be necessary. I plan on stripping the remaining leather and then filling in the finger joints with some high quality wood filler. The joints are already so fine it won't take much. That should be all it takes for making it light tight. A final sanding with very fine sandpaper (up to 600 grit), and then a coat of varnish should make it shine.

    Boy, the more I hear about your varnished Panoram, the more I like it. Ken Ruth has my ragged looking one, and when he is finished with the mechanics, I will strip the remaining old leather off of it and varnish it.

    Well, I have all my heavy duty tools out, so I'm ready to start in on tearing apart the 4C . . . I'll be back on-line later to report what sort of mess I have made of things.

    Well, sports fans, I dove into the bowels of the Panoram 4C last night, removed the swing lens, bellows, and the mechanism from the camera, cleaned it up, straightened up a bend in the "U" spring and a mashed & bent gear tooth, and put it back together . . . except for the bellows which are shot.

    Then, SURPRISE! The darn thing works like a champ! I guess all it needed was a little cleanup to remove rust and dirt from the mechanism and a little straightening of bent parts to get it going. Well, I did have another surprise . . . I didn't have any leftover parts!

    After I removed the swing lens & bellows, the tensioning lever, and the shutter release button, I wrestled with the question of how to reach inside to remove the 4 screws the hold the mechanism mountong plate in place. Then I got hit by a B.G.O. (Blinding Glimpse of the Obvious) . . . I had a stubby little screwdriver, about 1 1/2" long, that came with a phonograph cartridge that I had recently bought, and it fit those little screws perfectly. I did see that I had to pull the mechanism out carefully, as the spring to keep tension on the shutter release lever is loose in a hole in the wood at the top of the camera and falls out when you remove the mechanism. Fortunately it droped into my lap, so I didn't lose it.

    The winding mechanism is frozen solid and won't turn either way, so I will fix it this evening.

    That's where things are at this time.

    Sounds like it's moving right along.

    Well, I finally got the winding mechanism back together and it works fine now. Taking it apart wasn't too difficult, but putting it back together was a major hassle.

    Looking at Patent #1,023,933, Figure 5, the three little round things (#17), are pushed by little springs (#18), jam between tapered spaces on the 3-lobed cam (#15) and the outer housing (#14 in Figs. #3 & #4), thereby preventing the winder from turning backwards and loosening the film on the take-up spool. Those little round things aren't balls, but rather tiny cylinders that have to stand up against their individual springs while the outer housing is put on. That's the hard part!

    Well, I greased those little rascals real good to hold them in place while I installed the outer cover, but since they are held in place inside the outer cover by a small amount of spring tension, without the cover they present an overall diameter which is larger than the ID of the cover. That meant they kept turning sideways or falling over as I attempted to put the cover over them.

    Finally, my slow hillbilly brain figured that I should wind a piece of thread about 2 turns around them and pull it tight to push the balls against their springs and decreasing the effective diameter of the cam, spring, & ball assembly so that the cover could fit over them. Once I got the cover over the assembly and about halfway on, I was able to release the thread and remove it then push the cover the rest of the way into place and secure it with its 2 screws.

    All total, it took me about 2 1/2 hours to work on the mechanism and get it working, about 30 minutes to remove, disassemble and clean the winder, and about 3 hours to put the darn winder back together!!

    I'm tired . . . think I will go to bed early this evening.

    Panoram Shutter Issue

    Hello all, sorry I've been out of touch for a bit. Been intending to post info on what I've figured out by messing with my 4-D. This is my first semester of grad school - and it has been a while since I've worn my school shoes - so I've been feeling like I'm in the center of a tornado. But anyway...

    Looks like you've been making a bunch of headway EuGene. Guess you've figured out the screwdriver thing. But just in case anyone is wondering about a small short screwdriver to get at the screws that hold the mechanism in - I found that the one that came with an eyeglass repair kit from the corner drugstore worked well. I filed the head a little to turn the screws and cut the end of the handle off to give more clearance. But it probably wasn't necessary.

    My current issue is the shutter firing part doesn't release the lens as it should. There is a part on the spring catch (#74) where it engages with the lever (#70) that catches on the main plate (#65) and prevents firing. This is at the location of the catch (#73). It looks as though this is part of the design of the spring catch (#74) and not a modification, so I'm hesitant to file it off. But it seems to me that by doing so, I would solve the issue. If anyone has any advice (or even knows what all that described) please let me know. I think there is a photo of this part attached if I did it right.

    Well, I've got to get back to my reading for tomorrow. I'll check the thread soon.

    Forgot to mention that all the part numbers are from the patent #689,159.

    As for a bellows. The ratty old one I removed seemed to be made of an ancient suede/velvet mix and that the knowledge of creating a new piece of this material passed with Mr. F. A. Brownell. So I went to Tandy and they did inform me that it is true, the crossbreeding of suede and velvet has certainly been lost. I did get a nice piece of soft, almost velvety pigskin in black to use. I think it will work well. We'll see.

    Ron, that soft pigskin sounds promising, so I am anxious to find out how it works out. Since you were able to get it already dyed black, I am wondering if they sealed the pores in it? Also, if it works out, we could all use ordering info, such as catalogue number and the ordering address (snail mail & on-line, or 800 number for call in orders). I'm definitely keeping my fingers crossed that you have found the right stuff to use with that pigskin.

    Another thing that I have been mulling over is making some sort of adapter/shim type thing to glue, friction fit, or otherwise attach to the film spool spindles to make the 120 film spools fit a little better without being so wobbly. The holes and keyway are large and fit very loosly on the Panoram Model 1 spindles which were made to fit the smaller holes and keyway on the 105 size film spools. I would suspect that the looseness could cause a bit of binding and twisting of the film, which might contribute to the occasional tendency for the film to come out of the track and drop down into the camera.
