  Hello Ron Overs
  What an elegant design! I have been looking at your new Overs Action
(patent pending) and comparing it with S&S and Langer. I find your jack
spring very interesting - a form of single-winged - but it must be very
strong to give the required hammer-rise: how thick is the brass wire for
this? And your jack toe (tail) which should roll on the button and not rub.
One thing I think is due for further thought (though I am sure you have
considered every possibility!) is the access to the jack regulation screw.
This type of through-the-let-off button is darned difficult to access. Room
here for someone to invent a very thin flexible shanked slot-head tool... I
can just about picture it... The angle of the capstan is also an excellent
idea. It conforms to the radial movement of the lever (whippen) and
presumably the lever bearing block is aeriated for strength and lightness.
Are the rails of wood or extruded alloy? Are the action parts other than
wood? Is there a third drawing which shows the action in the "drop"
position - ready for repetition?
  I wonder how your action compares to Signor Fazioli's - which I have never
seen.
  Yes. It's very elegant!
  Herr Calin T must be very envious!
  Kind regards
  Michael G (UK)
