Sad about the CAL400. Newbie question: what do watch repair technicians usually do for worn pivot holes like this? I imagine trying to put in a bushing that small would be a challenge. Could one (dare one) drill a socket for a jewel bearing? Can anything he done here?
... thinking about this a little more deeply, it might be fun to acquire some plain steel hands and learn to blue them myself.
I'm sure that this won't be the most cost-effective way of fixing my specific issue, but I've been enamored with blued parts for a very long time and it would be delightful to be able to blue my own hands, screws, etc. in watches I make for friends and family.
I do have a stupid threshold question before going down this path, however -- there's a brass tube component that connects the hands with the pinions. Can one blue a set of steel hands with this little brass tube present, or does it need to be removed first? If the latter, this is going to be beyond me.
I figured out earlier that my CAL 400 ( CAL400 ) did not run not because of the balance jewels or the balance assembly, but because the escape wheel pivot holes are worn both in the main plate and the train wheels plate. The escape wheel pivots were really busy and dug a trench for themselves. Now I have a digital camera attached to my trinocular microscope so I could take a picture of it (i am still experimenting with it, not correctly set up yet and I probably will need an extra barlow lens.) I am very happy that I managed to solve the mystery even though it took me several weeks to figure it out. I am sure an experienced watchmaker could point this out in minutes as the pallets did not behave normal, i just did not know that what I can see was not normal that time.
Train wheels plate:
I have more recent Seiko movements 7s26, 4R36 and 6R15. I do not have Seiko greases but have some Swiss oils and greases. What do you recommend instead of the S4 and S6?
I think I could make use of Moebius 9501, I'm also looking to replace D5 with HP but not sure whether it's the 1300 or 1000
