One adjustment sets the dado kerf width reference.
The second adjustment sets the groove width automatically taking the dado kerf width into account so the groove width can be set using the piece to be inserted into the groove.
It requires the resultant groove width to be greater than the dado and also requires more than one pass.
Yes, I do understand. I achieve that same setup on my Mark V by carefully moving the rip fence so that it touches the blade (the teeth not the body). With the rip fence in that location, I set the magnetic ruler to zero. The left face of the face is now calibrated to the right side of the kerf.
By doing this, I have achieved the same as when the #3 reference surface (the fixed reference on the Matchfit) touches the blade. Thus no need for the third screw in the new tool.
The difference between the two screw stops on the Shopsmith Cross-Cutter (when properly adjusted) equals the desired width of the dado (taking kerf width into consideration). If these screw stops are not set accurately enough, the Cross-Cutter provides a means to tweak either setting.
I have not received my Cross-Cutter yet but I do believe that both the Cross-Cutter and the Matchfit will perform equally well at their assigned tasks. I chose the Cross-Cutter primarily because it is "micro-adjustable".
Shopsmith should really take Peachtrees lead and post a video that depicts the virtues of the Cross-Cutter.
That's my position and I am sticking to it!
