I agree too in that using something that is already crowned would be quicker than first setting them flat and then crowning them later. I know because this is how I've done it for the past 35 years. Of course they must be squared first and all that, but this can very easily be done using a slightly beveled leveling board. What became confusing was wondering if my level board had warped or what certain manufacturer's actually recommended. That is, crown or no crown. That never was really answered other than Steinway and as is often the case, some do it differently than others. Some crown, some don't.

Fortunately for me, I'm not concerned about a "true crown." I'd be willing to bet that keys squared in this manner would be indistinguishable from keys squared flat and raised by punchings. I think we've taken this past the point of reason now. ;-] My point was only that I didn't think it was necessary to change the way we think of leveling keys for a crowned vs. flat keyboard.

For a true crown the keys would have to be square in the middle and then gradually lean as you move towards the ends. If you started with a level and square keyboard, and then shimmed the rail, this would happen naturally. Sure it would add a step, but it would only take about 5 minutes to execute it.

If you want flat, use a flat stick, if you want crowned, use a crowned stick. Leveling with a crown takes exactly the same effort as leveling without if you have a crowned leveling stick. William R.

Then you could put as much crown as you like and there would be a perfect graduation in key heights from middle to ends. -- Ryan Sowers, RPT _____ avast!
