Building wood gear
clocks since 1971
Stains & finishes
Gears #30 and #33 are clamped to shafts #12 and #34 by means of key #31 pressed into slot. If the press fit is not enough and there is slippage, turn key over and file tab to suit.
If clock does not work, try lifting swing shaft #8. All gears should now rotate by themselves. If not, remove upper and middle gear assembly. Close frame with just the lower gear assembly in place. See if it spins freely. It must have a little end play. Do the same with the other 2 gear assemblies, one at a time. Check swing arms #48. Swing shaft #8 must spin freely in supports #4. If not, rub candle wax on the shaft String #9 should be positioned in the middle of the square hole in #5.
If clock runs sluggishly try removing the (2) swing arm weights #49 from swing arms #48 and add extra weight to the weight frame #50. This will speed up the clock and overcome the friction allowing the bearings to run-in. After a day or two, remove the extra weight and replace the swing arm weights and the clock should run smoothly.
If the escapement mechanism is not running smoothly, check: when pawl #7 is in contact with front sprocket #18, there must be clearance with rear sprocket #20 in order to rotate. If it does not miss the rear sprocket , then use the sanding stick to remove a small amount from the point of contact on pawl #7. Then check when pawl #7 is in contact with rear sprocket #20 in a similar manner. Adjust the time by moving weights #49 on swing arm #48.
The closer together, the faster it will run. When winding the clock by hoisting up the weight, hold gear #30 so that it will not rotate.
WARNING: ...Keep away from small children. Kit contains small parts, and could cause chocking if swallowed. We will not be held responsible.
