Gluing up a separated back is a good excuse for buying a set of clamps. Consider how small the surface area is that is being drawn by carriage bolts, especially since the back surface is probably not a particulary hard wood. Use cauls for each clamp, but leave yourself enough room to drill and install bolts after the clamps have been drawn up tight. I prefer picking up the clamps on a return service call when I do this job in the home. Carl
