[CAUT] Key leveling

[Jim Busby]

Don,

Boy, you sure know how to destroy my hopes of buying a new tool! ( :-)

If they come to the next convention with some modifications that address dip I'd certainly be interested. But... nothing like the tried and trued methods!

Regards,
Jim

Jim,

Good idea about the touch weight - but . . .

The sensors required to accurately measure touch weight resistance are very expensive.  You and I can change weights and watch to see which one moves the keys, but the machines have to have super precise sensors on the tip to measure the resistance.

It can be done reasonably well in a factory situation where the volume justifies the costs, but it's my guess that it would quadruple the price of this rig to add a touch weight sensor!

I agree with others - this is a nifty setup, but kind of overkill.  Kawai uses a laser sensor to do a similar thing in the factory, and it prints out a paper tape showing which punchings to put under each key.  Then the action is pounded by machine for a while, and guess what?

- Technicians redo the leveling the old fashioned way.

:-)

Don

List,

Those of you at the convention saw this new tool. I told the fellow that after leveling with this device if you could add a weight and accurately measure dip that this would be, IMO, even more valuable than the key leveling aspect. What do you think? I like to see new/different ideas.

Simply put for those who weren't there, this device sets up and measures key height by contacting each key and then a computer tells you to put in whatever punching is needed for a "one pass" key leveling job. That's how I understood it anyway. It seems like a consistent weight carrying the probe to the bottom of the key dip is the next logical step.

IMO this tool is pricy for just leveling. Add dip, maybe I'd consider it. Figure out how to lay perfect dip and aftertouch... well, I'm even more interested! Until then I'll do it the old fashioned way.
