I am in the process of building a stairway using a Kerf-Wedged Dovetail through Mortise and Tenon joint to tie the treads to the stringers. I am building this stairway of Butternut treads and Red Oak, full face stringers and Cherry wedges. There will only be end stringers and no risers. I've cut all the wood to outer dimensions and am ready to begin cutting the joints. Just curious to hear from someone who may have done this before.

My plan for the joint dimensions are a 1x8 by 1.5" long tenons cut into 2x10 treads. The wedges will be 3/16" wide at the butt with a 1/4" kerf to the edge of the tenon. The treads are housed into the stringer 1/2" at either end. The Oak stringers are 2x12" so i have 1.5" of tenon plus 1/2" of housed thread coming flush to the outer surface of the stringer which will all be exposed.
