Bluegrass, you have a lot more talent then me...I can't even get the boxes from Dadant to line up straight...I could only imagine trying to build them myself....I know I would have plenty of scrap wood to start the wood stove! And to do it one handed, wow...impressive!
I am doing it one handed because I am holding the camera in the other. I have one router...the rabbits I cut with the fence mounted on the router and after assembled I move it to the router table and cut the hand holds in. I find that if I cut them in before assembly I am more prone to mistakes in getting the top and bottoms in the right place.
I end up with plenty of scrap for the wood stove too. I started with enough wood to build 11 boxes and ended up with 9 after a few miss-haps while cutting the frame rests in.
