One recommendation for those of you who wish to go with the milled frame design and something that I forgot to do and wish I did. I recommend using an overcut feature for the corners of the finger joints to eliminate the radius corners left from the radius of the bit.
This will help the finger joints fit together nicely. I used an 1/8" end mill and I needed to go back with a wood file and file out the corners. So I suggest an overcut to keep from doing that.
