This is how the clock will look on my wall which is primrose yellow.  I may yet reprint one or two parts in a different colour eg. the hour gear which is orange ATM may look better in red.

The whole gear train except for some of the bearings and axles.

Seconds wheel printed etc.

A few changes.

Here's just the drive chain.  This is just the gears and ratchet wheel without the main axle and bearings.

Explanation :- 

1. Green wheel is seconds with red pinion attached
2. Red and blue gears form the seconds to minutes reduction with the pinion above
3. Yellow wheel driven by friction from blue gear - provides ability to set time.
4. Pink pinion on yellow wheel drives minutes to hours reduction
5. Orange and pastel pink gears plus pink pinion reduce minutes to hours.

Red and orange gears are fixed.  Green, blue yellow and pink rotate on ball bearings.  The ball bearings keep the wheels aligned.

I think this is just about it for the overall design.  Some fine tuning to do and the parts have to be fitted to available ball bearings.

Seconds and minute hand added.  Need to add another hour gear before the hour hand.

For reference hour pinion centre is 87.625mm from axle.

Minute wheel was oversize - now corrected.

As mentioned in the initial description, this clock uses epicyclic gearing to provide the 60:1 and 12:1 reduction ratios between seconds and minutes and between minutes and hours.  This is described in my DIY Skeleton Epicyclic Clock with 3D Printed Gears but I shall repeat it here.

The principle involved is that when a pinion is moved round two spur gears with just one tooth difference and one gear is fixed the moving gear rotates by one tooth for each revolution of the axis of the pinion.  So if the fixed gear has 59 teeth and the moving gear 60 teeth the gear ratio between the rotation of the pinion axle and the moving gear is 60:1.  This is the ratio required for seconds to minutes in a clock.

When the gears are different by two teeth the moving gear turns by two teeth for each revolution of the pinion axle thus if the gears have 22 and 24 teeth the gear ratio becomes 24:2 = 12:1.  This is the minutes to hours ratio.  However, it works out better to have more teeth and a lower modulus to make the motion smoother for 3D printed gears.  Using 44 and 48 teeth gives a gear ratio of 48:4 = 12:1.

Model of clock "works" in case.  The dial isn't really white, it's black but the CAD software adds white lines round everything.

I'll try a close-up as you suggest.

Update...

With frame.

More added.

A couple of changes needed - the peg on the rack lever wants to be smaller and the small snail cam also wants to be smaller.

A couple of views of the latest clock assembly.

The striking mechanism - more parts to add yet.  Shown about to strike 12 o'clock.  The snail cam rotates anti-clockwise and winds the rack up one notch whilst striking once per revolution.  The pawl holds the rack as the tooth on the snail cam leaves the rack.  Once the appropriate number of strikes has occurred the tooth on the small snail cam contacts the lug on the end of the rack and stops.  The mechanism remains in this state until just before the next hour when a cam on the minute shaft causes levers to hold the small snail cam and lift the pawl, releasing the rack, which drops until stopped by the peg contacting the large snail cam (brown).  On the hour, the small snail cam is released and the pawl dropped onto the rack and the next hour strikes.

Next I shall be adding the parts of the striking mechanism.  The parts I had already printed were the wrong scale.  First component is the strike cam.  The spokes of the cam fit the spokes of the hour wheel.  The cam goes behind the hour wheel and will be glued to it.

I think I may be wrong in going for a very large escape wheel.  Metal longcase clock mechanisms have quite small escape wheels of 50mm or less so my original 100mm diameter wheel was already much bigger than standard pendulum clocks with a one second pendulum.  I have found out why my earlier recoil anchor escapement gave problems - the pendulum bob was far too heavy.  With the new lighter bob the earlier escapement may work.

Come hell or high water I shall get this clock ticking!!!  Just maybe not today!

Unfortunately U4 is not a transistor but an IC with 6 connections.  I guess only ZWO know what it is/was.

Still not working!  There are so many interdependent variables with the deadbeat escapement that I've decided to leave it for now and just make a recoil type escape wheel so that I can get the clock working.  I hope to return to the deadbeat escapement later.

Still to much overlap of pallets and teeth so have shortened teeth by 2mm to try again.  Now printing.
