1/4"x1/2" spline 1/8" kerf Half-size section detail Coving the Sides I build the lid as part of the sides, then cut the lid free on the table saw. The box has four sides of equal length with mitered corners. To reinforce the miter joints, I use a spline, which adds a lot of strength and a subtle design element. I also like to add a cove to the sides of the box. Coving, an act that is easily achieved using your table saw, can be done prior to building the box or after. I prefer doing it before, just in case a calamity of some kind happens, destroying all of my work to that point. The procedure is really quite simple. Basically, just pass the wood across the blade at an angle and take very light cuts, maybe 1/l6" at a time. I use an 80-tooth blade because it produces a cleaner cut and leaves me with less scraping to do afterwards. Less scraping is always a good thing. To make the cove pictured on page 70, bevel the blade to 45°. This gives something approaching a parabolic curve, but changing the angle of approach and the slope of the blade can produce a variety of profiles. 3/4" lid 173/4" 23/4" box 3/4" 41/4" base Elevation 1/8" 1/4" plywood 3/4" 23/4" ■ 1/8" lid removal saw kerf i i i i —r 3/4" 3/4" 1/8" saw kerf 3/4" Lid, box & base sections -3/4" dia. hole 3/4" -)f— 2"-f-Base stock plan ■ 1/8"x1/4" spline t 15/8" Remove waste (red area) with band saw or jigsaw 1/8" = 1/8" =
