You need to make curved molding, but you don't have the time or inclination to do the whole job by hand with carving gouges, and you don't have the money or desire to buy custom-ground shaper bits that fit your desired profile. That's OK, you can still make curved molding with this simple over-arm guide used on the router table. Using off-the-shelf router bits with this jig, you can create almost any curved molding profile.
