I have got 2 each 1 x 2 x 4' 2" and 2 each 1 x 2 x 2' 2" maple for my
coffee table frame and I would like to finger joint (box joint) the
corners with an odd number of tabs so that the longer front rail has
top and bottom tabs. I just can't decide on 3, 5, or 7 fingers. Or even
maybe 9 fingers about 1/4 thick. I will do the dados on my drill press
with saw arbor, blade, and cross vise.

Can you help?

Vary the pin widths and / or spacing to add interest. You'll have to
lay out the joint by hand and cut the slots by eye, but the result
might be worth the hassle.
