<html> Terry,    If you clamp a piece of 4" steel "U" beam, or C-channel across the rim directly above the belly rail, you'll have several options. You can get double-duty out of your pin-block supports at this point, or use a truck tire inner tube and air pressure. Medium-sized hand screws can be used sometimes, also. Depends on the length of the screws, but real good for dealing with odd angles. You can shape the ends of the hand screws for holding cauls or blocks. Also handy for certain bridge repairs, if you move the channel around. I had one years ago with four short-throw pneumatic pistons mounted equidistant that I used for various clamping jobs. That, though, was a little tricky. Those pistons could push ..... well..... realllllly hard, if I wasn't careful. One neat thing was the valve. I used an "always-on" push-button air valve, that could be used for a hammering action. Real handy for veneering. Just a couple of old-but-effective techniques. "ingenious/superior"? .... naw..... have fun, Guy At 08:40 AM 10/11/2004 -0400, you wrote: <blockquote type=cite class=cite cite>To those in the habit of gluing soundboards to piano rims......   In the high treble along the belly rail, the belly rail is commonly not vertical, but rather angled a bit towards the pinblock at the upper edge where the soundboard to rim joint is. This presents a bit of a clamping challenge. I have used go-bars in these kinds of areas in the past, but would greatly prefer to use a clamp. Also, when gluing the board to a cut-off bar in the area where the cut-off overlaps the horizontal portion of the belly rail (and this can be quite wide on well-built pianos) presents an area where a traditional clamp cannot be used. Again, one can use the go-bar, but I wonder if some of the wonderfully invent-ful participants of this list haven't come up with some kind of ingenious/superior method of clamping in these areas.   Ideas?   Terry Farrell   <a href="http://www.farrellpiano.com">www.farrellpiano.com</a></blockquote></html>
