Today, I spent time routing out the pockets under the shoulders (THAT SUCKED!!!!) and cleaning them up with a wood chisel (REALLY SUCKED!!!!) But, I made progress. I also cut out the center of the 3/4" leg layer.
Next up, I need to figure out the dimensions of the shoulder holes and start planning the cutting of the Center Leg (even though I ordered one from JAG). Looks like Matt McCormick's Blog has quite a bit of info about the center leg and how he put it all together.
