Starting with the tapered legs, there are several very simple jigs made that allow you to
choose your taper. First, you need access to either a table saw or a bandsaw. You can
develop a jig for routing the tapers. What tools do you have? Also, are you talking about
round or square legs?
The profile work on the table edge is fairly straightforward, too. It involves making a custom
swing arm for a router base and using a straight-cutting bit to gradually reshape the thickness
of the edge. Circles can also easily be cut on a table saw. When I say 'easily', I mean that
someone who has gained experience with table saw use, can make a super-simple jig that
will let them do this type of work.
I don't want you to be buried with procedure here without knowing what tools you are
familiar with, and I don't want to put your safety in jeopardy.
Use a router and make up a circle cutting arm take small passes and it will be flat like a coin
