Try This Versatile Mortising Jig
An adaptable clamping surface holds curved and straight parts alike
Synopsis: Learn how to build a versatile jig to cut mortises in three ways using a router. Michael Fortune first created this ingenious jig to make clean and accurate mortises in curved pieces. He soon discovered that the jig works just as well in straight pieces and is flexible enough to use for end-grain mortising, such as for slip tenons. Fortune shares detailed information on building and using the jig. The article includes a project plan as well.
