The link below should take you to youtube for a short video of the clock in action.

This was the start of it all - with no clock or use in mind other than to see if my gear program and CNC would work together - this is a 140 tooth 18” in diameter and matches 6 leaf pinion

The wind mechanism is a simple ratchet and pawl with two drums for winding and weight.  The details of the gears had to be reverse engineered from this point.

My calculations shows that if the pendulum has a period of .99 seconds and 78 pins then the escape turns once in 2.57 minutes and the great wheel once per hour.

This is the  78 pin escape wheel and is 14” in diameter.  This gives 1/2” between pins. The six leaf pinion is on the back side of this pin wheel.

The pin escape mechanism is designed for a 4º pendulum swing

The pallets (or ramps) provide a 30º slope for the pins to escape and are positioned such that the pin is at the top of the slope in a stopped or neutral position.

Instead of the two armed escape usually seen on a pin escapement I used 3/4” material and cut enough away to allow the pins to enter - find their along the ramps and exit

The time train is a direct copy of Clayton Boyer’s time train used on “Radiance”.  I like this mechanism because it doesn’t have an obvious gear reduction set.

Mounted on the clock the time train is the most un obtrusive that I have seen

The “dial face” requires some arithmetic in order to discover the numbers or you can just look and “know” without doing the math!

The pendulum is a “pierced” design that was cut on the small CNC.  By using registration holes I was able to cut the 40” pendulum rod on a 6” CNC

Until I get some sort of creative idea this is the pendulum bob.

The frame for the clock is just a simple arc and is cut from melamine covered construction board.

The gears on the test stand indicate that it will be a very forgiving design and the pallets are extremely easy to adjust.  The clock “went” from the first time I put it in beat.

The plates are separated with spacers and then bolted together

The front plate only goes to the great wheel to add support for the driving weights

All raw edges were painted white.

The clock is now assembled except for the the time train
