WoodMaster rig. (5/5), Jul 16, 2014

By John Majors (Wetumpka AL US)

Very High Quality. Perfect tight joint.
I use this on my wood master…
Only complaint is that the Woodmaster® has twin outboard routers that mount one up, one down. This makes it impossible to use the matched set simultaneously. I compensate by running the material twice utilizing an offset spacer. A little extra set-up, but still less trouble than trying to swap out bits and re-align bits (or have very large stacks of half-finished pieces)
