and assembling them pointsin over an appropriate frame; the grain will give a lovely octagonal pattern. However the joinery in the frame below will be tricky. This might be better as a veneer pattern! If you want a simple design for the frame underneath you want to keep the cuts few and symmetric. About the simplest would be in the diagram below.
Note that the diagonal edges in the middle are each more than an inch away from the center. If you wish to use tongueandgroove or some other routed edge pattern to make a strong permanent joint, you can easily push the top piece down and/or the bottom piece up to give a little extra wood along the long edge for jointing. On the other hand, if storage is a problem, this design would work well for a tabletop that disassembles into two halves, with folding legs and an unglued lap joint. Good luck! Corey wrote back
Corey, If you are making RD's first design then I wouldn't measure angles at all. Mark 2 foot measurements down one side of the sheet and then on the other side 1 foot, 3 measurements of 2 feet and the 1 foot. Join the markings as in the diagram and cut along the lines. If you are looking at RD's second design then the angle between the 4 feet 9 and 3/4 inch sides and each 1 foot sides is 90 degrees. All the other interior angles are 45 degrees. Harley
