As above the crutch (leader) should be rotated 90 degrees. If is is easy to do so, remove the suspension spring and the pendulum so the crutch can be operated by hand slowly and the action of the escapement can be observed.
Safely let all power off the mainsprings. Apply finger pressure to one of the gear wheels in the normal direction of rotation.
Use low-power magnification if needed to observe the action of the escapement.
at this stage, the escapement will be in one of the following three states.
- working
- locked
- escape wheel spinning freely
- If the escapement is working, gradually decrease the centre distance between the escape wheel and the pallet arbor by tiny amounts until the escapement stops ticking and locks. Now very slightly increase the centre distance until the escapement only just begins to operate.
- If the escapement is locked, gradually increase the centre distance between the escape wheel and the pallet arbor by tiny amounts until the escapement begins to operate (tick).
- If the escape wheel is running free, gradually decrease the centre distance between the escape wheel and the pallet arbor by tiny amounts until first the escapement begins to tick and then locks. Now very slightly increase the centre distance until the escapement only just begins to operate.
The escapement is in its best state of adjustment when it is only just ticking i.e. slightly greater centre distance than the locked position.
If the "drops" (free) rotation of the escape wheel are wildly different, yo may have to adjust internal drop. As above, a total last resort. Can cover that later...
The above and the good advice in other posts should get you ticking.
Re-fit the pendulum and turn the crutch through 90 degrees.
Hope this helps.
PS. Spinning the wheels as you describe under power doesnt alas tell you that much. Your re-bushed mobiles should drop totally freely from shoulder to shoulder when the frame is inverted 9when all the power is off of course). If they don't. Go back to that first and check for uprighting issues and de-burr all the new holes on the inside of the plate...
Good luck! Yes a video with the escapement operated by hand i.e. slowly would be really useful.
