I'm wondering if someone 6' and shrinking might benefit from this as well.

It might take a while to get the feel but you could do it. Same with dip, just takes practice which will yield pretty accurate results. Your method would probably work but I haven't tried it.As to the glides, I don't change them because it will affect the leveling. You have a good point about the wear factor but it has not caused me a problem yet. I still have to do some fine leveling in the piano. By the way, Harbor Freight sells a small folding stool on wheels that puts me about the right height for key leveling and damper work on grands. Makes life a little easier.Best,Dale</blockquote> -- Greg Newell <A HREF="mailto:gnewell@ameritech.net">mailto:gnewell@ameritech.net</A>   </body> </html>
