I have asked here before about a source for nylon washers to replace the steel ones used under the cams that lock the front standard of the versions of Tachi 4x5 Hope similar to mine. None I have found anywhere is close to sufficiently thin. A new thought just occurred to me today, however, and I would like to ask if anyone has a model using nylon washers—reportedly used in at least some of the later production runs—and would measure the distance of the post base to the hole for the screw that holds the cam on; perhaps the hole was located higher up on the nylon-using models to allow a thicker washer. About the thickest steel one I can use is 0.2 mm, and I am currently trying out a 0.05. For my camera, the washers inner diameter is 5mm; the washers I have (Japanese ones from a model/hobby shop) have an outer diameter of 7mm.
