Cutting the stub tenons

To connect the center pieces of the panels on the bottom of the bench I had to use a stub tenon and groove joint, heres what one looks like-

(I did these at my school with my mentor Mr Breigle)

On my peice the stub tenons fit into the dadoes that I cut last week.  Cutting the stub tenons was pretty difficult in terms of the set up and checking.  I couldnt just use a measurement because it might not macth the dado exactly.  So we set up whats called an auxilery fence over a dado blade on the table saw. and you move the fence over sligthtly each time until you have the fit you want with the dado.  Then you do the same thing with moving the blade up.  This process is pretty difficult to explain so here are the instructions from the plan.  

Here are some photos of my work and video of me cutting one on the table saw-
