In other words, if the coil height is, for example, 3/16", then there should be approximately 3/16" available between the bottom of the pin and the bottom of the pin hole/bottom of the pin block. The other dimensions then sort themselves out if one chooses the right pin size and block thickness. Does that make sense? It almost always works out to approximately what you calculated: between 1" and 1 1/8" of pin in the hole. </DIV> <DIV> </DIV> <DIV>Paul</DIV> <DIV> </DIV> <DIV> <DIV><STRONG>"If you want to know the truth, stop having opinions" (Chinese fortune cookie)</STRONG></DIV></DIV> <DIV> </DIV> <DIV> </DIV> <DIV>In a message dated 03/24/07 18:18:04 Central Daylight Time, jonpage@comcast.net writes:</DIV> <BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: blue 2px solid"> <DIV> <STYLE type=text/css> .aolmailheader {font-size:8pt; color:black; font-family:Arial} a.aolmailheader:link {color:blue; text-decoration:underline; font-weight:normal} a.aolmailheader:visited {color:magenta; text-decoration:underline; font-weight:normal} a.aolmailheader:active {color:blue; text-decoration:underline; font-weight:normal} a.aolmailheader:hover {color:blue; text-decoration:underline; font-weight:normal} </STYLE> <STYLE type=text/css></STYLE> <DIV>><FONT face=Arial color=#000000>How much of pin should ideally be in block?</FONT></DIV> <DIV><BR></DIV> <DIV>As my grandmother used to say to my relatives when divulging ingredients</DIV> <DIV>for recipes for her fantastic pies: Enough but not too much.</DIV> <DIV><BR></DIV> <DIV>Generally speaking, The top of the pin usually is anywhere from 7/8" to 1"</DIV> <DIV>above the plate.
