Hoping this is a good place to ask - I have to make an oval sign out
of 3/4 MDF. I am using a jig saw to cut the basic shape. My
question is what is the best tool to sand to the finish shape? If I
use a belt sander or orbital sander, I can get the shape, but the
edges are not perfectly 90 degrees to the surface. Is there a tool
that I could use ( or a jig for a tool) that would finish the edge to
a 90 degree angle?


rec. woodworking might be better. If you cut with a trammel point you
should get pretty good circularity. A bandsaw with a jig would do better,
as would a router. If you know someone with a good disk sander, a circle
jig similar to the bandsaw jig also works. Does for me, anyway.
