This week, (25-29 September) Tetsu and Dean worked on some outstanding tasks and projects.
Tetsu finished the last of his seven movements, then went straight to work on hand-turning a balance staff, which was completed on Thursday. These were two significant milestones in the Fullskill program, congratulations!
From the chronograph course, Dean overhauled an ETA 2894-2 movement. The chronograph module was challenging as it has a number of springs and only one bridge to hold them down.
Dean also worked on a vintage Rolex 1520 movement, in particular the hairspring and barrel bridge. The hairspring was quite bent, so it took a bit of time to straighten it out.
A worn barrel arbour hole on the barrel bridge was causing the barrel to lean over far enough to contact the bridge, so Dean drilled out the hole and installed a bushing.
