Octagonal, hexagonal and even square pedestal bases for tables can be aligned perfectly for gluing with heavy-duty plastic sealing tape. Cut your bevels on the workpiece edge and lay them with the inside face down and one end butted to a straightedge. Align the bevels so they touch along their entire length and tape them securely. Next, carefully flip them over and apply glue to the joints. Then stand them up, fold them together, tape the final joint and pull the shape together with belt clamps. Tip: To get the angles for your shape, divide 360 by the number of sides you want, then divide this number by two to get the bevel angle for each side.
