So I used JB Weld to epoxy the brass pieces to the steel blade, and also drove three 3/16" brass pins through the brass and steel to maintain the proper alignment. Oh, you need a carbon steel bit to drill carbon steel. The blade itself is only .020", but you will ruin titanium bits, they will just burn up, and probably ruin the temper on the blade. I bought a spade bit, it was $13 from amazon.com.
