Basically I put two 1/4" holes into my program spaced exactly on centerline for sides 1 and 2. I then ran the program and drilled just these two holes into my waste board. I aligned my stock as best I could to these two holes and ran the same two holes. Flipped it over and used 1/4" steel dowel to align and clamped it down. Then ran the same two holes on the opposite side. After that I ran all of side 1, then flipped and ran all of side 2. Worked out great!
