Can one edge glue accurately enough to get a real even = subpanel-to-subpanel joint (no step from one to the other)? I was envisioning gluing up a = whole soundboard panel that was thicker than needed and then (after driving = the panel to a shop with BIG sanders/planers) running the whole thing = through a planer device to get your nice consistent final (before tapering) = thickness. If I am understanding your process, you do the above on your smaller subpanels, but then when you have glued your subpanels together, you = do any slight evening up by a hand plane or sanding (or maybe even that is = not needed?)? Thanks.</DIV> <DIV> </DIV> <DIV>Terry Farrell</DIV> <DIV><FONT color=#000080></FONT> </DIV></BLOCKQUOTE> <DIV dir=ltr><FONT color=#000080>No. We thickness to 9 mm then sand = to final thickness.
