<WBR>Rex<br> <br> Yes, this is what I call the "pear" knuckle. The back edge of the jack should be in line with the "front" part of the wood that comes down.

I had my brother-in-law take a picture of the hammer shank so that you could see how it is made. The picture is a bit fuzzy (the camera focused on the back wall instead of the hammer shank), but you can see that there is nothing that looks like a knuckle built into the shank as one of the referenced pictures shows. The shank, knuckle core and flange are all one piece of wood over which the leather has been stretched. </SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"> </SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Is this what was called a Thayer knuckle in some of the references or is this a “pear” knuckle as Wim suggested?</SPAN></FONT></div> <div class=M soNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"> </SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I was going to ask some questions about the regulation procedures, but think it might be better first to see if we are all on the same page with what is being discussed.</SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"> </SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Thanks again.</SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"> </SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"> </SPAN></FONT></div> <div class=MsoAutoSig><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Rex Roseman</SPAN></FONT></div> <div class=MsoAutoSig><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Roseman Piano Tuning</SPAN></FONT></div> <div class=MsoAutoSig><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"> </SPAN></FONT></div> <div class=MsoNormal><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt"> </SPAN></FONT></div> </div> </div> <br> <div id=AOLMsgPart_4_e9a8d044-f154-476b-a5a7-25d33ead8c41 style="MARGIN: 10px"><A href="http://webmail.aol.com/37955/aol/en-us/Mail/get-attachmen t.aspx?uid=1.20898972&folder=Inbox&partId=4" target=_blank>[Image Removed] <br> </A></div> <div id='u8CABD68F6B3478A-9D4-1A7D' class='aol_ad_footer'><FONT style="color: black; font: normal 10pt ARIAL, SAN-SERIF;"><HR style="MARGIN-TOP: 10px">The Famous, the Infamous, the Lame - in your browser. <A title="http://toolbar.aol.com/tmz/download.html?NCID=aolcmp00050000000014" href="http://toolbar.aol.com/tmz/download.html?NCID=aolcmp00050000000014" target="_blank">Get the TMZ Toolbar Now</A>!</FONT> </div>
