Ron, Hey, are you experimenting on my D?? <G> While you're at it, I'd be interested in what Don Mannino says about wheel (caster) orientation. While the wheels (The larger brass wheels) point out, how much do they change the keybed vs. pointing in? Don says it changes regulation, and I think it does, especially on some pianos. But how much? From what you found with the lyre (only .02" difference!) I wonder if caster orientation may be a factor not considered in previous posts. IOW, if this DOES make a big difference and was not taken into consideration maybe all previous measurements (not yours) were bogus, or suspect. Ya think? Best, Jim <<<If one was interested in learning something, one should be so inclined as to attempt to find out. I just now did that, on a NY D, with a straightedge and punchings.>>> Ron N
