bent nail teeth to be replaced., 2. Cut out the bad section and trace tooth
pattern using good teeth., 3. Fit replacement wood block using slight dove tail
and glue., 4. Saw the teeth using a jeweler's saw., 5. and 6. Finish teeth
with file to shape and sand smooth and flush with original wheel.

Boardman & Wells Wooden Movement, Type 9.223, circa 1835
This is believed to be a Boardman & Wells movement, Type 9.223. It is a
30-hour Terry style wooden weight driven time and strike movement. The movement was
acquired without a case. One main wheel had three teeth replaced with bent nails,
and another wheel had two damaged teeth. Most of the pivot holes were badly worn
and the movement was very dirty. The various pivot holes were bushed with bushings
made from Delrin-AF®, which is a low friction Acetal polymer that can run without lubrication. The "nail
teeth" were replaced, as were the other damaged teeth. The picture sequence
below shows some of the bushings and the steps taken to repair damaged
wheel teeth. The repaired movement run strong and
strikes using less than 2 lbs. weight but I will run it on about 2.5 lbs. Lacking space to continue running the movement on my test rack after a few weeks the movement was set aside to wait for an appropriate case.
A few months later a customer brought in a Boardman and Wells clock with an identical but damaged movement. So this movement of mine became an organ donor giving up its strike side main wheel, second wheel, and second wheel arbor and pinions. The rest of this movement was placed in the spare parts bin for some months until I decided that this would be a good movement to test whether the two missing wheels could be hand-cut and whether the missing arbor and pinions could be made from a single piece Delrin® stock. The answer was yes and the results are shown in the pictures at the left. So my Boardman and Wells movement is again running exceptionally well and still waiting for me to build or find an appropriate case.
