With the playing surface nearly complete, we'll turn our attention to the leg assemblies.
Notice on page 2 of the Free
Woodworking Plans that you'll need two pieces of 1x3 at least 12-inches in length. You'll also need a 1x3 cross-brace cut to 20-inches in length.
Using your compass, lay out a half-circle on one end of each leg (as shown on page 2 of the measured drawing) and cut the curves using your Jigsaw or Band Saw.
Next, drill a pilot hole for the bolt (to attach the leg assembly to the frame) at the center-point where you positioned your compass, again, as shown in the measured drawing. The holes should be just slightly larger than the diameter of the bolts you purchased for this purpose.
Finally, measure down each leg 11-3/4" and make a 25-degree mitered cut as shown on the plans. (This angle will be 65-degrees from the side of the leg, as shown in the diagram.) This mitered edge will eventually be parallel to the floor when the game board is in use.
With all of the parts cut, now would be a good time to give every piece a good sanding. Be sure to sand the playing surface and the dried wood putty so that the surface is as smooth as possible.
