    We found a book digitizer at a thrift store that has a gooseneck mount for the camera. It will do macro or close in viewing which we found is great for watching the escape wheel interact with the pallets on our Atmos.

    We have a picky little guy that would run with 450 so more degrees of rotation then after a couple days we find it stopped.

    This is post cleaning unit.

    Watching the pallets interact with escape wheel is interesting.

    Every once in awhile the tooth seems to hang up on the pallet and it does not clear, the pendulum pushes it back against the tooth, then it goes.

    On some other teeth of the escape wheel cause the rotation to of the wheel to go slightly backwards as the tooth slides off the side of the pallet.

    Looks like maybe the escape wheel teeth need close look under microscope.

    Here are some photos of what we can see with the camera in use.

    The largest image was using zoom on the phone to enlarge what was on the video screen.

    The camera was $5.00 at a thrift store, good investment!

    We have been collecting assorted cameras and microscopes for aiding tired eyes.

    This one has the goose neck so it can be placed in any position.

    We have an Epson that works well but it Jas a folding arm so desk work okay but sideways forgetaboutit.

    This one also has different resolution and capture so lots of fun things.

    Also picked up a Nikon stereo scope that works much better than others.

    We found a film of sorts on the pallet jewels that the simple brushing did not clean off.

    The escape wheel also had microscopic stuff on the teeth that we could not see with other means.

    Simple cleaning of the pallets and the escape wheel improved it greatly.

    The camera was great in that it will zoom the image to where the pallets barely fit the screen.

    In this view one can see the escape wheel tooth slide on the side of the pallet.

    It slides just a tiny amount but the sides may be missed as we think the faces see all the action and the side just stops the wheel.

    Carefully scraping the sides with a tiny sharp puck under microscope reveals a film of dried mystery stuff that added just a bit of friction.

    Yesterday we gave the clock the above attention and started it with less than 360 degrees rotation.

    Today it is over 480, before it was maybe 420 but not consistent.

    Will let it run a few days before we put the face and hands back on.

    Most video cameras run at a certain frame rate depending on the standard the camera is made for. Digital or analog, its not a continious flow.

    Like movies on film run at 24 frame per second. Thinking to actually see what is going on you would have to go at a super high frame rate.

    Just a thought.

    This is an Atmos...

    No need for speed...

    Camera has zoom that makes the single pallet view fill entire screen.

    Built in capture great for comparison shots.

    So this morning it was stopped again.

    We had the camera in place so we gave the pendulum a gentle push with a single stringed artist brush and noticed the right pallet would not clear.

    It has power transfer to roller but at the very end of the stroke where the roller is cleared and just before it hits the front plate blanking pin it stops.

    When the pendulum spins back around it slides backwards slowing down the unit.

    It is rotating well past the exit point but the fork stops just before banking.

    Sometimes it would be okay after a few tries or it would stop.

    We captured the image and we assumed the angle on the pallet was good.

    It had a groove that we stoned off and the angles looked same.

    This clock has always been "funny".

    So we grab another clock that is a good runner and look at the action and we notice our angle is way off.

    We forgot to capture the example, but the good one when escape tooth is in the middle of the pallet is more open on left side while the other is more open on the right.

    When they are at exit point it looks like it is hooked.

    We stoned it just enough to tilt the face similar to the good one but not near the extreme and it seems to be working better.

    The teeth slide off smooth.

    Photos are where the tooth is sticking.

    A rough drawing of the angles and a post repair photo.

    The last photo looks fuzzy, at 1600% zoom of something the size of a fly's behind through a spaghetti sized hole it is not too bad.

    It needs to run a week before we claim done...
