Rainy this morning

Rewiring of power supply has been undergoing all through the night just in front of my laboratory. This kind of reconstruction is inevitable for the Development Station here. Not a few Special Purpose Vehicles with Crane Outrigger were terminated in our neighborhood.

As for old Minolta MC Rokkor 50/1,7 lens modification converting on Canon EOS Digital mount, flattening of flange surface was performed to insert 100/1000 mm thickness sim between the construction. Some empty aluminum can was utilized for the purpose making holes with special circular device. Old grease was removed thoroughly to change heavier friction resistance into lighter movement of focusing ring following as later models. Microflon powder would be applied in helicoid grooves. Probably final setting of infinity position of lens element would be done today.
