David= Ilvedson <DIV style="PADDING-RIGHT: 5px; PADDING-LEFT: 5px;= PADDING-BOTTOM: 5px; BORDER-LEFT: #000000 3px solid;= PADDING-TOP: 5px"> <HR> Original message From: David Love= <DAVIDLOVEPIANOS@COMCAST.NET> To: 'Pianotech'= <PIANOTECH@PTG.ORG> Received: Wed, 13 Apr 2005 20:51:07= -0700 Subject: Key Clamping Jig       Attached are the= photos.  These are simple trap springs screwed into= a long piece of pin block scrap which has been screwed down= to a slab of something I had laying around.  The pin= block material is shimmed up off the deck to allow the lip to= slip under.  Once the key is placed under the clamp I= depress the spring slightly while holding the key. = The release of tension on the spring pulls the key slightly= toward the pin block stop as otherwise there is tendency for= the key to drift back while the keytop remains stationary and= a gap can form at the front.  As you can see, you can= also use this for clamping a set of sharps.  If= you install tops without fronts, you could make the jig with= a stop for the keytop recessed whatever distance you want= underneath and behind the line of the larger stop for the key= front.  That way you can index the same amount of= overhang of the key top for each key.  Since I= don't install keytops without fronts I didn't bother to do= that.  David Love davidlovepianos@comcast.net= <HR> <CENTER><IMG src="mhtml:file://C:\Documents and Settings\David= Ilvedson\Local= Settings\Temp\xPlus\D5A5C9FC-E997-44B3-AB0C-A4D62DE96453.mht!CID= :{4A8BFDE8-145F-40E4-A1A8-D2B0E9299DDD}/P1010005.JPG"></CENTER> <HR> <CENTER><IMG src="mhtml:file://C:\Documents and Settings\David= Ilvedson\Local= Settings\Temp\xPlus\D5A5C9FC-E997-44B3-AB0C-A4D62DE96453.mht!CID= :{A0A8E44A-5097-4E17-857A-AC721A7920F7}/P1010006.JPG"></CENTER> <HR> <CENTER><IMG src="mhtml:file://C:\Documents and Settings\David= Ilvedson\Local= Settings\Temp\xPlus\D5A5C9FC-E997-44B3-AB0C-A4D62DE96453.mht!CID= :{BA667E2D-6D78-400D-8CFD-B7BACA76527D}/P1010007.JPG"></CENTER></= DIV></BODY></HTML>
