With the dual mainspring barrels back in place, I turned my eye to the most difficult system to re-build, the co-axial escapement. Comprised of two tiny wheels, the sun-shaped co-axial wheel, and the pallet fork. While I was able to successfully set the wheels in position, after placing pallet fork bridge on top (which supports the upper side of these otherwise freestanding components), I was unable to maintain the wheel position and alignment while carefully installing the pallet fork. While my hand was perhaps steady enough for the task, I couldn’t find the right amount of pressure with my left hand to secure the plate while still offering a bit of wiggle room for the components to settle back into place after the pallet fork is seated. Cue Victor for the save.
