I'm a beginner and this is an AS1951 which I got working after a clean and oil. I didn't remove the mainspring. I have only a few few sizes of winders and usually have much difficulty with them. I did remove the barrel lid and ran it through the ultrasound. I then added a few dabs of 8200. The jewels got 8000 and the pallet stone 9415 (all Moebius).
The amplitude is better than I usually get and the rate is ok. How would you read these pictures? Is all ok? What are all the stray dots?
Looks like a flat crystal, easy to get and replace. You can find the part, as well a press and digital calipers on Ebay. You can also fit a sapphire crystal for few dollars more. The cheapest place to buy is Alixepress if you don't mind a longer shipping time.
The small motor, copy of Foredom, found on any online platform, is perfect. Then an assortment of hard felt wheels, mandrels for paper and small wheel, and compounds.
BTW we have a section dedicated to discussing tools, as well one where it's considered polite to introduce oneself. You may ask mods to move your post using the report flag top right.
