Introduction: Splined / Keyed Mitre Sledge / Sled and Box - Building and Using on Table Saw

About: Artist and maker.
In this video I made something which I have wanted to build for sometime now.  A keyed mitre sledge, which is used to cut keying slots across the outside corners of mitred boxes, which are then filled with glue and a slice of another material to increase the strength of the join.
