A few years ago Norm made a nice basic stand with splayed legs. Does
anyone know what angles to use for the legs and stretchers when they
are to be splayed?

I don't know anything about the angles for the planer stand, but I built a
wheeled cart (24" deep x 48" wide) and have my planer bolted to one end of
that. My benchtop drill press is mounted on the other end. I added a couple
of drawers underneath to keep my drill bits and accessories, and sanding
supplies in the second one. I store miscellanous items in the space under
the drawers.

Since the cart is on wheels I can easily roll it out when I need it, and
store it up against a wall when I'm not. Works great!
