This is nothing less than absolutely brilliant!! I have made models from scratch before but this is on another level. I have yet to make 100% scratch made metal parts but I do have a 1935 Auburn Speedster in the works that I am finishing. It has all metal exhaust except the muffler. I can't find or machine a small enough piece with the patience level I not possess without a lathe. I don't want to spend another $3.65 for an aluminum bar that I will only use about and inch off and have the rest lying around as I already do with a 3/8" bar at the moment.
