Throw away the Crown Jewel of Perfection of piano manufacture?  Get thee behind me!  Block my hammer! Still, the visual does have some degree of visceral appeal...

I will also look at the nap of the buckskin. I have already sanded the bottom edge of the tail to remove the sharp edge. <blockquote type=cite class=cite cite> <dd>Are you making a laminated checklist of all these suggestions?   You could teach a <dd>class next year.   Or sell the list.  ;-)</blockquote> <dd>I am saving all the suggestions for future references. I don't know if I will have enough material to teach a full class, but maybe a mini class. As with all educational material, the information will be free for the asking. :) <dd>Wim <blockquote type=cite class=cite cite> <dd>Ed Sutton</blockquote> </dl></blockquote></blockquote></body> </html>
