You drill = a hole in the rib, insert pin and cut it off 1/8 inch or so. The spruce board = is soft enough that you aren't going to split the rib. Put 3 in a long rib. The = ends are tacked with a tiny finish nail for the prep work. They act as = locater pins when gluing.

I'm looking for a few more details describing your = (or anyone's) center-pin-anti-skid methods. I was planning on trying something like that for my next board. I imagine the pins penetrate = the panel side of the rib maybe 4 to 8 millimeters (just enough to = gain solid footing) and penetrate the panel just a few millimeters (just enough = to hold in position) - is that correct? Do you taper your ribs = before gluing to panel - how do you handle running a pin through = the thinner ends of the rib? Do you just use two pins per rib (obviously on = short ribs) or do you maybe use three or more on the longer ribs?</DIV> <DIV> </DIV> <DIV>One other thought on glue cleanup - one thing that I was = going to try to implement - which relates to access for cleaning the glue joint = squeeze-out. Adjust the top beam of the pneumatic clamp so that the = hose can inflate most of its diameter (obviously maintaining full = contact/pressure on rib). If the hose is allowed to inflate a goodly amount of its = diameter, rather than allowing only a half-inch of its diameter and blobbing = over the sides of the rib, you should be able to maximize access to the = rib/panel joint for cleanup. Or at least I will be trying that next time.</DIV> <DIV> </DIV> <DIV>Thanks.</DIV> <DIV> </DIV> <DIV>Terry Farrell</DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; = BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: = black"><B>From:</B> <A title=Erwinspiano@aol.com href="mailto:Erwinspiano@aol.com">Erwinspiano@aol.com</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A = title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech@ptg.org</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Saturday, September 20, = 2003 10:16 PM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Glue cleanup on = ribs</DIV> <DIV><BR></DIV> <DIV><FONT face="Times New Roman" color=#000040> <FONT size=3>     Trix and I pressed up a = S&S O board today.
