I went to bed to early last night. But glad I saw this first thing today. These are just so neat. I have a question though, in your directions for the wing block. That ends up making 2 1/2" blocks which would make an 8" 4x4 block, right? I started making the wk 16 block yesterday, and my brain is still dead. Trying to make a 12" 4x4 block. I know if I just did sqaures, each sqaure would be 3 1/2", but the original cutting piece has to be larger, and the 30 degree temp is 3 in. Should I just add 1/2 all around or maybe make it 4" to start. Am I making any sense? Help.
