Router Table Mortiser

(from Lumberjocks.com)


I have been making several small end tables with mortise and tenon joints and wanted to see I could design an apparatus to make mortises for the table aprons.Below are a few photos of a my Gen I mortiser that works on a router table. This mortiser has the workpiece plunge into a the fixed router bit instead of plunging the router into the workpieceThe workpiece is clamped to a carriage which can move up and down (Z axis). The carriage is made from aluminum plate and moves up and down on v-bearings.There are two other 'fences' and three 3/8-16 adjusters; the Y adjuster is for aligning the workpiece for and aft with respect the router bit, and two X adjusters to limit X travel to the left and right. My router table also has a lift, so the depth of the mortise of controlled by the lift.After adjusting the Y axis adjuster to align the workpiece for and aft, and the two X axis adjusters, the workpiece is plunged into the router bit and moved left and right between the screw stops.This setup works well as is, but I am sure I will make some refinements down the road to make it easier to set up and operate.
