I started out by ripping some plywood to 3 inch strips and 1 and a half inch strips, The 3 inch strips will make up the bottom portion and the inch and a half strips will be used for the top. I then decided to cut rabbits on all the strips before I glued them together this saves me from cutting dadoes later, just a little quicker.
I then loaded the tenon into easel. (if using my easel file then it will be the one at 0,0 so just delete the other one at 0,4 for now ). Then make sure the tenon is cut out on the “outside path” and the outside of the material is cut out “on path” It is also important to make sure the outside portion is cut first. This is down by selecting edit and then going to “bring forward” a few time until its all the way forward.
I then load the mortise into easel. (if using my easel file then First delete the tenon at 0,0 and move the mortise over to 0,0 from 0,4). Here you want to make sure the tenon part is set to “fill” and the outside portion has a depth of cut of zero. You also need to turn the whole thing 90 degrees. here you may need to add to the thickness of the tenon by adding some width. I find with loading SVGs from sketch up, when ever you use the “fill” it cuts it about 25 thousands to small. So in easel under the shape tab, I add the 25 thousands. Another important note is to make sure your position is set to 0,0 that way you know to position the centre of the bit right at the corner of the material.
