Inertia - was Grand Touch

[Mark Bolsius]

Hi all and Ron,

One also has to remember that often with long existing companies, the reason
for doing something in a particular way may have been lost - so much
corporate or community knowledge dies with certain people and then the
'discovery' process starts all over again. IOW - they might have forgotten!

This is more than possible with a company like S&S - and many others.

But I agree, the assumption that friction is correct, because that is
someone else's job is dangerous and foolish, often resulting in less than
excellent touch response.

Cool discussion, folks
Cheers
Mark Bolsius

Surely they didn't actually test it years after the patent was 
issued and found it unnecessary. Wouldn't they have to file a 
patent retraction (an idea that's time has come)? Probably 
just saving lead. Then again, their practice of individual key 
leading with whatever the weights and friction levels of the 
action gave them, would be more easily and "accurately" done 
with smaller weights further out than with bigger weights 
grouped at the center. Now that I mention it, how does moving 
weights in toward the balance rail for better performance 
through inertia control reconcile with their custom of 
individually custom leading keys without regard to action 
friction levels? Doesn't really compute.
