The escapement -- a spring detent escapement. The detent return spring is an alarm clock balance spring whose tension is adjustable. The detent lever is steel, as is the detent pallet. The passing spring is a bit of 400-day suspension spring bolted to the lever with with a 00-90 screw. The banking is a 0-80 set screw.
The escape wheel has 15 teeth and is driven by a contrate wheel. The balance wheel is 3" in diameter. It runs dead true, trued in a set of full-circle inside jaws, a property of the Taig Microlathe softjaw chuck. There are small, moveable weights on the arms of the wheel to pemit poising. I had hoped to jewel the bearings, but never got that far.
There is a window in the front of the clock so the rear-mounted escape wheel can be seen. The dome is 9.5 by 6 inches. The dial and hands are homemade, using computer drafting.
Beautiful little gears, made with my homemade flycutters. These are about module 4.5. The lantern pinions were made in a homemade rig on the old Mosely watchmakers lathe.
The regulator. The torsion spring fits through a 0.006" slot in the block, which moves to effectively change the length of the torsion spring.
