Servicing an Agfa Isolette V camera with a Vario shutter, part 04

This Agfa Isolette V is a nice, simple 6X6 folding camera. This model was made between 1950 and 1952. As this one has the accessory shoe on the right of the top cover, it is from the earlier production. Later examples had the shoe on top of the finder. As you might expect, it could do with a little bit of attention at this late stage. Servicing continued.
Consumables used servicing camera bodies:
I use naphtha (cigarette lighter fluid) for cleaning metal parts. CRC Heavy Duty Lectra Clean for dried grease that the naphtha won’t dissolve. A generic wax and grease remover to soak mechanical parts prior to cleaning in an ultrasonic cleaner. Glass cleaned with normal domestic glass cleaner.
Parts are lubricated with Inox MX6 (a synthetic grease), Rocol Dry Molybdenum paste, MicroLubrol Helimax XP helicoid grease, graphite powder, or graphite grease as needed.
Leatherettes are glued back with Ados F2 adhesive.
Consumables used servicing shutter and lens assemblies:
Naphtha (cigarette lighter fluid), or occasionally CRC Heavy Duty Lectra Clean. Lenses cleaned with normal domestic glass cleaner.
Parts are lubricated Rocol Dry Molybdenum paste, MicroLubrol Helimax XP helicoid grease, graphite powder, or graphite grease as needed.

Just imagine, if Chris fights for minutes with a spring - how long would it take for one of us?

Very interesting video Chris. One question, why did two of the aperture blades have a flat side and did it matter which position they were placed during assembly. I don't think you mentioned it.

[@ChrisSherlock]

The missing edge on two or three of the blades would most likely have been just down to the manufacturer squeezing an extra row of blades out of the sheet steel. It served no other purpose, at least in this shutter, and has no effect on the action.

@@ChrisSherlock Thanks Chris. I love your videos and that little matter intrigued me.
