Next, the mainspring was lightly greased and replaced in the barrel.

Replaced the Balance wheel without hairspring and roller table so I could test that the deep cleaning of the jewels and pivots now let the Balance wheel run freely, which it does!

Deconstruction video made up of photographs from stripdown of the movement.
On stripping down this scrap movement I found the following items that need attention.
Firstly the whole movement is rusted up, the mainspring and balance wheel did not move.
During the deconstruction, I found the mainspring had been fully wound up and this caused the click to be jammed on ratchet wheel, plus the barrel was stuck to the barrel bridge by dried out grease!
After carefully taking and train wheels out from the movement due to them being very tight in the pivot holes, it is clear the whole movement had been over oiled, and because the movement had not been used for a long in oil had dried out and everything had become stuck.
One Dial and case screws are missing, and the roller table on the balance staff is loose.
So now the movement is completely stripped down to its fifty-nine parts, it’s time to clean all the items well.
I found an old Pocket Watch case which I hope to use with this movement. The case is marked Dennison Watch Case, with the stamps of ALD (Aaron Lufkin Dennison), the hallmark of the lion passant (.925 purity), the Anchor (Birmingham), letter h (1907), and the case number 2776. So the case is a Waltham Pocket Watch model size, it will need a replacement button and crystal.
I spent a bit of time in the workshop today having a practice at making my first watch Balance Staff.
This photograph album and video are relating to my first “practice” of making a Balance Staff out of 1.4mm Blue Steel on my Vintage Telco Watchmakers Lathe.
Today arrived my new Kafer JKA-Feintaster Watchmakers Precision Gauge. Which I purchased new from Kafer in Germany through Mapra technic in January 2019.

I tried out my new knurling tool today on the
refurbished Unimat SL 1000 Lathe. After turning down the steel rod to the correct
sizes, I knurled the handles for grip.
