[CAUT] cutting

[G Cousins]

Chris,
Have you heard of TouchRail system?  I just installed on on an older D and am very impressed with the results.
The action was a mis mosh of Renner, Tokaiwa and SS parts on a typically heavy leaded keyboard with long back checks. 
I believe we all have some of these "beasts" in our inventories.
I was able to even out the touch weight throughout the entire keyboard. Weighing is now evened at 51 grams. Quite remarkable.

I am continuing my data on this new product but initially a VERY pleased with the results. I eventually plan on a write up of my findings.

Just a couple of thoughts on cutting the punchings 
at the balance rail. We can cut the punching to raise or lower the Balance 
Weight (both down weight and up weight move in the same 
direction) depending on which side of the center line of the balance pin 
hole we glue on the punching. There are several gradations available 
each way depending on just where we choose to cut. 
The "accelerated action" patent refers to the 
method of weighing off the keys from the balance point out to the front key end. 
The half round bearing is a separate patent. While it would be cool if someone 
actually considered the reduction in "sliding key ratio" I believe the main 
concern was in reducing friction. This only works until the top of the bearings 
flatten out and become de facto rails. The two patents have in practice 
become part of the marketing concept of the "accelerated action." Probably 
because half round bearing friction or sliding ratio reduction doesn't 
sound all that sexy. Of course no one weighs off accelerated action style 
anymore so what is left is the half round, or just a sexy sounding meaningless 
concept called "accelerated action." Personally, while as a player I might wish 
for an accelerator for the action from time to time, I think that in general it 
would be difficult to regulate. Besides there are enough pedals for two feet 
already.
A properly married action ratio and hammer 
weight, with a well balanced and regulated action, does everything my 
digits can ask for within the context of the cumulative ear training I 
have received. Now if I could just blow into 
the thing...
