I don't know what kind of steel aperture (or shutter) blades are made of. It seems to be some kind of 'springy steel'. The surface of many types of that kind of sheet is black or dark blueish due to oxydation during heat treatment. If this layer is scraped off I found most types of steel can be soldered. Plain steel can be soldered quite easily. In this case I used electronic solder wire but I found that plumbers' soldering paste has a flux better suitable for metal-to-metal soldering. I would have made a shot of the repaired aperture blade but I did not want the disassembled iris to lay around for too long. BTW there seem to be quite a few old cameras (6x9 folders etc) of which some of the aperture blades are disintegrated. It is not easy (and takes a bit of time, mostly for reassembly) to fix that but it seems far from impossible in many cases. |
