Ghost in the machine? (a Columbia 9000)
Posted: Sun Aug 16, 2020 11:33 am
I started to service my Columbia 9000 portable today after having already heard the familiar sounds
of a main spring in despair when trying carefully to wind the motor.
I then cleaned the case, inside and outside, removed the rusty lock, adjusted the spring lids, discovering four needles made the mechanism to work badly, also causing the lid easily to fall down. Someone had used a tooth pick in the past to try solving the problem without removing the motorboard, not having detected the stuck needles behind the lid stay mechanism. Needles removed, problem solved...
Unscrewed the motorboard screws, put the motorboard on an old newspaper, and allowed the motor to fall into my lap when unscrewing the motor screws,
Grasping the motor, read the number..HMV 270D, had a look at the governor parts, nothing missing or destroyed,( thanks for that)...
Turning the motor around in my hands once again, my eyes fell on an odd mark on top of the steel. What the heck!!
Looking more closely at the mark with a looking glass, I decided the service was over for today.
Shutting the lights off, closing the door to the garage room. Done.
I know I have a superstitious trait, but really?
I wanted to share it, since it really is weird, and the more I look at it, the more I see, like a Rorschack test.
So what do you see here? Just a splash/spot of old grease and oil...OR?
