    Re: Sinar Norma Adjustments

    If I understand you correctly, I think that you should be able to put shims on the too long one. You should then put the shims closest to the knob, so that the thread does not screw all the way in. I hope that makes sense.

    I have to check but I think all four of mine are the same length, for 4x5" and 5x7".

    My Normas have two washers/spacers per knob. Some type of plastic I think.

    Actually I'm looking for a source for some replacements; Couldn't find what I want at McMaster Carr.

    Anybody have a good source? Also will try Lowes

    I thought about this today too - Microtools perhaps? But I am also looking for thin shims, can't figure out what they might be called in german, have only found thicker stuff.

    Hello
    I found this address:

    https://de.misumi-ec.com/vona2/mech_...0/M3302020000/

    Lots of shims in a wide range of materials.
    Unfortunately, I haven't measured the Norma washer yet ...

    Re: Sinar Norma Adjustments

    I went downstairs and measured the shims. I thought it was only one at first, but it was actually two. The rod itself measures 5 mm in diameter at the ends. The inner diameter of a shim is 7 mm, outer 12 mm and thickness is 0.2 mm, measured with a micrometer. So two shims, 0.4 mm in total, isn't exactly a lot. The shims are made of metal in mine, by the way.

    I found these at McMaster Carr and ordered a box of 25. Inside diameter is 6mm, outside 12mm, .2mm thickness. Stainless Steel we will see if they fit.

    When I measure the inside diameter with my Sinar Norma metric ruler, it appears exactly 6mm.

    Re: Sinar Norma Adjustments

    I measured the diameter with a vernier caliper. I think the outer diameter is of less importance, and my shims anyways fit a bit loose on the rod, so I think you will be fine.

    I'll have to check the measurements of the other shims (on the shift and swing) too. I have a few challenges on the project Norma parts, a replacement shoulder screw is needed and a hex screw for one of the monorail sliders have gone missing somewhere in years past. We'll see if I can figure that out.

    Re: Sinar Norma Adjustments

    I measured the other shims.

    The shift has two shims, inner diameter 5 mm, outer 12 mm and thickness is 0.08 mm, so I guess one shim with 0.15 mm thickness could also work. The swing has only one shim, with the same inner/outer diameter, but with 0.15 mm thickness. All of these shims are dependent on how the camera was adjusted. All of them metal. The only shim that I have found that is some sort of plastic is the one on the coarse focus screw.

    I also measured the rod shims a second time, and yes, they are also 6 mm on the inside.

    Norma Washer and McMaster Carr substitutes by Nokton48, on Flickr

    McMaster Carr is super quick to ship. I ordered these yesterday.

    On the left, the darker washer is original Sinar Norma. In the packet are the replacement washers from McMaster Carr.

    They are identical when laid one on top of the other.

    These are stainless steel washers. Hopefully that is OK
