    I need Washer item 15 which was missing from the camera I'm repairing.
    Rollei part number is 03605.00.0

    Best I can measure its 27.8mm OD, 27.4mm ID, .2mm thick.

    I don't have the tools necessary to make one and am not willing to have one machined as its likely out of my budget.

    Uh, your diameter numbers, 27.8 and 27.4, leave a thickness of .2mm. Very very thin. Where are you getting your numbers from?

    Can you take photos of what you have? Having just stripped down a Roleicord V this evening, the part I think you are referencing has very different dimensions than your numbers. Maybe send me a message.

    Its the washer that goes between the cocking/release lever and the face plate the shutter mounts to. Without it the cock/release lever, item 13, drags when the shutter and operating lever assembly are secured to the face plate item 17A. Item 13 should float.
    Its impossible to photograph something you don't have or measure it. Measurements are of the ring lip at the point where it comes through the operating lever and thickness of the face plate/lens frame.

    So I think the brass washer shown here is what you want. I see where you got your measurements- you were measuring upper step on the dark flange.

    The washer is not as tall as the flange step. That step is what indexes the shutter block on the lens board. So the washer itself is 0.2mm thick, allowing part of the flange to still project and center the shutter on the lens board. And the outer diameter of the washer isn't really very critical- it is, as you know, providing a smooth surface for the shutter cocking/release collar or whatever it is called to rotate smoothly.

    The part I have has an inside diameter of ~25.86mm. The outside diameter of the upper step of the dark flange on the shutter body is ~25.77mm. Confirm this. If this looks like it would work, drop me a message and we'll figure out how to get one to you.

    Oh, have you contacted Harry Fleenor? Your images are accurate and he'll be able to send you the right part from them, If he sells parts, etc. I don't have a real inventoary of spare parts, so if he can help you that'd be great. If not, contact me.

    Being its a flat brass washer I might be able to cut one from the brass stock I have on hand.

    Turns out I was assembling it wrong, sort of.:sad:
    The correct order of assembly on the rear of the lens is MXV lever, plastic retainer, aperture lever, cocking/trip lever, brass washer, lens carrier, retaining ring. The bearing looks like a retaining ring and does not need to be removed from the shutter.
    diagram 2.jpg
    1. shutter; 2. MXV lever/plastic retainer washer; 3. aperture lever, not visible; 4. cocking lever; 5. bearing; 6. washer; 7. retainer, not shown.
    I made 2 spacers from a scrap sheet of film, .007 each, to fit between the bearing and shutter case to get enough clearance between the shutter and lens carrier so the cocking lever would operate without binding.

    Now there's a problem with the focusing and the retainer on the focus knob won't loosen. The left side of the camera has been hit and had some superficial damage that i was able to reform to acceptable but the right side moves out first followed by the left side when focusing. Nail polish remover is soaking on the focus knob.

    Are we having fun yet?

    The lens board on the V, Va, and Vb are pretty much the same, I think. I'd be really leery of being able to reform a lens board. So many points need to maintain position!

    How does one remove the focus knob?
    Diagram shows it threaded but it refuses to budge. I've soaked it in nail polish remover and tried pliers and a rubber strap but no budge.

    Do I need a blow torch or hacksaw?
    The plate with the filter bayonets was deformed as was the left focus arm, had to add .020 shim between the lens frame and focus arm to get the lens to sit level/even.

    I recently had good luck soaking the focus knob outer ring with Tri-flo oil overnight. Another possibility is to soak it in ammonia for a bit- ammonia can break up aluminum oxidation. But I am not certain what ammonia will do to the finish of the part. Jammed parts like that are always a problem. Try putting the camera in the freezer for a few hours, soak it in boiling water maybe? The goal is to break apart the binding parts, so if you use heat let things cool down and contract before any wrenching.

    For the mechanics of removal I use a rubber stopper to twist the retaining ring off. If needed I'll put a slip joint pliers around the main body, with a heavy cloth wrap to protect it. In one very difficult case I ended up destroying the pin in the knob that serves as the infinity stop. Turns out that the wire in a push pin is just slightly bigger in diameter than the original (.06mm or so) so I broke away the plastic of the push pin and drove it into place and it worked fine.

    It's rare that Rollei makes a misstep but every now and then- the Rolleicord V focus knob is one, the Rolleiflex 2.8C plastic tabs is another misstep.

    You can pretty much install the bayonet ring best as possible and then use it as the leverage item to reshape the front.

    I've got a Rolleicord II fully disassembled. I thought this one would be a quicker fix, it isn't.
    I'll try some penetrating oil on the stuck knob if the focus is good with the current lens position (taking).
    Thanks for confirming I'm not missing something.

    Well...... I filled the knob opening with Liquid Wrench Penetrating Oil and let it sit for 2 days. Drained, no budge. Filled with TriFlow for a few days. Drained, flushed with degreaser, but still no budge.
    I bought a bag of rubber stoppers off ebay (anyone want some?) but it would not budge. Today I put the large end of a 5 1/2 stopper on the knob, placed a piece of 1/2 x 2 x 3 wood on the stopper, placed my body weight on the wood while standing and holding the knurled portion of the knob with the other hand and it broke loose.

    Every now and then, Rollei messed up big time. This design is one of them. The plastic tabs around the shutter release and flash sync on the 2.8C is another mistake.

    I bought a used V some time ago that had a free-wheeling focus knob. Turns out the pin that serves as a stop had broken off, most likely when someone tried to open the knob. Fortunately the metal stud on a thumbtack was the right diameter to replace the pin.

    Suggestions for the focus arm insert (at arrow).
    focus-arm.jpg
    I have acrylic, ABS, oak, and possibly fiber board. Appears to be phenolic resin.
    Its not listed as a separate part in the service literature.

    Delrin. High-density polyethylene. UHMW polyethylene. Go to TAP Plastics. Take the part along so they see how big you need and they might just give you a shaving. Use heat to meld it into the opening.

    Acrylic will crack, either from direct pressure or from slow decomposition over time. ABS just doesn't have the desirable wear and pressure qualities. Wood or fiber will compress over time (high density high oil wood might work, but oak ain't it).

    Many plastic food storage containers are HDPE- look on the bottom- '2' If you want to sacrifice one you can probably find a section thick enough, usually a rim of some sort. Tic-Tac container top is HDPE. UHMW is the best but probably overkill for this level of pressure and wear.

    San Francisco store 30 mile round trip, some employees swear plexiglass is acrylic.
    San Mateo store is 50 mile round trip.
    By the time the acrylic fails it will likely be ready for the junk pile.

    No, I disagree. Acrylic fails 'catastrophically,' meaning that it will crack and fall into pieces. It is simply not made to be under pressure. And getting the arcylic to stay will be difficult and so it will be prone to pop out of place (pressure again). Also no lubricating quality.

    If your only choice is acrylic or ABS, use ABS. Or as I suggested, cut a piece of HDPE from a food container.

    Of course if you are the only one who will be using the camera, do what you want. But if you plan to sell or pass it on, please don't use acrylic.

    No, Dr. Sledgehammer and Nurse Anvil are anxiously awaiting it.
    No HDPE food containers, just soft s___.

    Alrighty then, you probably should listen to the other suggestions you get from people who have done this a few times before, and who have spent the last couple of decades working with plastics in prototyping and machine work. Best of luck in your various endeavors.

    You can breathe easier as the acrylic with a touch of Pliobond and JB Weld would not stay in place. I cut a piece of ABS and tried to heat mount it but no go so I trimmed an edge to fit snugly and applied a small amount of E6000 https://www.amazon.com/E6000-237032-Craft-Adhesive-Clear/dp/B004BPHQWU . I will cut off the excess tomorrow and check it for hold.

    There's an ebay seller listing new old stock parts and said he probably has a new one but has not gotten back to me after 3 weeks.
