    Have you considered using an Instax Link Wide printer for the ejection base? It’s much thinner than the LomoGraflok back (and the Instax Wide cameras it’s based on). It has an LED strip that I think exposes the film as it passes through, right before it reaches the rollers. I keep wondering if you could remove one side of the entire housing, so that it can be attached to a frame that’s open to the lens side, and exposed in the traditional way, but then ejected using the Link Wide mechanism?

    Nice. Ive been wanting to find out more about this process. Have you considered using magnets for the film holders? This would allow you to ensure exact and repeat alignment as well as the film flatness, and allow you to fine tune the flatness adjustments by varying the thickness of metal strips used with the magnets.

    Very interesting technique! I'm not after alternative darkroom printing, but to have an alternative to the very expensive color negative material and doing the compositing with scans in Photoshop (or whatever). Since it needs 3 B&W negatives, it only is cheaper with cheap film stocks like Fomapan. Can you show some results?

      I do the focusing with a printer paper, the UV make it glow and you get only the UV part of the light. At the moment I am only looking at the paper but it is surprisingly accurate.

      The back springs is the only thing that I could not replicate, too much pressure. The back 2 pins are the pivot. the front 2 pins are smaller and do not stick out sideway as much, they barely come out past the metal side plate. When I push forward they are clamped.( I have kept all the clamping assembly of the original lens.) I just copied the original lens.

Did you use the weird shape hole for the back pins axle and the front pins ? How did you grind the cam ? I made one in 3D for a 150mm lens, and I ordered a copper machining and a copy in 3D print but the accuracy couldn't be better than 0.1mm. I wish it could be 0.05 at least.

    • @n.defrance
      @n.defrance 6 месяцев назад

      I used the original back pins and I inserted them in the 3d print, That was not a good idea and I should have made some new one. For the front I made new pins of the correct size and glued them in the 3d print. I made a cam from a piece of metal because I wanted to keep the original one intact. I adjusted it by focusing in the ground glass at a certain distance fitting the cam at the same spot and taking it off and filing it with a flat file until I had the correct focus in the viewfinder. Repeated the process at different distances and smoothing in between. After I checked everywhere and adjusted until it all matched. That took the best part of an afternoon.

    • @n.defrance
      @n.defrance 8 месяцев назад

      It would depend on the initial dc motor speed. The motor needs to have around 106rpm at 12v. The motor I use can go up to 132rpm at 15v if needed. 4.5v :40rpm 6v:53rpm 9v:80rpm 12v:106rpm 15v:132. Or you could change the gears sizes, I made the calculations for mine more than a year ago so can't really help you on that. If you type "MFA 919D1481" on the website rapidonline or farnell, it will show you the motor.

    • @n.defrance
      @n.defrance 9 месяцев назад

      For the tube I used latex tubes. I used a small amount of silicone to make sure they stick to the connectors because those are not really good at grabbing the tube. For the pump I was talking about the first replacement pump that I used. You can see it on the tensioning plate, it is a small rectangular box in the video. The original pump worked great but it was part of the electric motor, I wanted everything on 12v. You may be able to reuse it, I haven't tried. There is another way to modify the RCP20 by changing just one gear, it could another option.
