I have asked about this before - but since it has been about a year, here goes again. 
I think that a Club Footed escapemen t would be a worthwhil e addition to the escapemen ts that you already have in the program.

One particula r advantage of this type of escapemen t is that the pallets can be made easily adjustabl e allowing for adjustmen t and experimen ting with both the lock and the drop.  This makes control of the pendulum swing something that one can play with.

Having made a couple of these I have found them really forgiving and fun to work with.

What features of the club foot do you find to be the most important?  Most of the designs I see have long skinny "legs" that would be very weak in a wood clock.  It may work great in brass though.

I have been experimen ting with 3D printed clocks and found that the tradition al deadbeat escapemen t does not print well.  The pointy tips get shortened slightly.  The fix is to give some width to the escapemen t teeth while reducing the pallet width by the same amount.  This gives a much more consisten t printed escapemen t.  The impulse surfaces are similar to a club foot escapemen t.

The advantage s 1  The club footed escape wheel teeth are very robust and do not have small delicate points to worry about and the impulse face is shared by both the escape wheel and the pallets. 2  the impulse faces share the work so that the reaction of the pallets is easier control, 3.  The actual pallets are usually individua lly adjustabl e for depth allowing a mechanica l adjustmen t on an assembled unit (clock).

I find these points make it really nice for wood.

Hi:

   Im running an experimen t on making a parametri c clubfoot in Vexx
to see how it woudl scale as a drop in replaceme nt for the normal lever types.

 Ill let you know how it works out and in the end probably at least add access
to the test code that will hopefully generate one to normal specs.

May be a couple weeks ..
