Renner

[Charles K. Ball]

Dear David,

I have installed many sets of Renner shanks & flanges with no problems with
the spread.  I usually go for the Hamburg dimension (17 mm knuckle
position), especially on B's and D's; however, if you are retaining the
original New York repetitions, you might want to use the "modified" shanks
(16.2 mm knuckle position) instead, or you could shim the repetition
flanges with 1mm veneer just above the flange screw (to keep the jacks at
90º to the shanks).  Best would be to use the Renner repetitions as well.

I would remove leads starting from the balance rail; this will bring the
greatest improvement in terms of reducing inertia.  If the action is
already quite light, you should be able to remove a ton of lead.

Regards,

Charles
