Simple question, slightly OT. Why is the condition known as "Pulley Key" <div class="gmail_quote">On Tue, Sep 6, 2011 at 12:17 PM, <<a href="mailto:johnparham@piano88.com">johnparham@piano88.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Joe, "insert gummed travel paper into the hole and > force the pin down on it, to hold it in place, until the glue, (it's > actually hide or fish glue, depending on the type of gummed paper you > have.<G>), until the glue has sets." I like this idea, but I have a few questions about your methodology: Specifically, how do you insert the gummed paper into the balance rail hole. -ball it up and stuff it in? -roll it up and carefully insert into the hole? -put glue in paper first or after it's in the hole? -size the hole with a spare balance rail pin or by putting key back on the keyframe?
