Jay, I'm new here at the forums and just wanted to offer my suggestion. My first build I made a drill from a long rod of the desired diameter, heated one end and flattened, filed the edges to size and put about a 20 or so degree point, then filed to a cutting point.
Worked great and I had it for later use.
Just a suggestion, and good luck!
Forgot to add, I flattened about 2" and after filing to size rounded the edges, it makes a guide that way.
