Cycloid Reducer.

[Hessel Oosten]

Great Paul/Tweakie !

If I remember well NYC CNC (on YouTube) once made a hypocycloid reductor of a normal speed electric motor to 1 rotation in 30 years !!!
They did put several reducer layers behind each other, so it's clear now that Paul is --not-- fully ready at this moment .... ;)

p.s.

My interest in this subject is caused by the fact that I'm trying to build the Woodward gearless clock
(which has in the John Wilding drawings, also a daisy wheel for the 12:1 reduction for the dials).

  Nice work. Nice to know the numbers work out in reality. :)
