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. Terry Farrell </BLOCKQUOTE> <DIV dir=ltr><FONT color=#000080>No. We thickness to 9 mm then = sand to final thickness.
