|Spot on! Mitering the downtube to the headtube.|
Despite all of that, I would really love to get a milling machine at some point in the future. Mitering by hand is a much slower process than cutting the tubes in a milling machine would be, but it still requires a fundamental understanding of the design of the frame. With the limited amount of time that I have to spend in my shop, I'd like to take all possible measures that I can to speed up my process without sacrificing quality. And, it's not like the tubes come off of the milling table 100% perfect - they still require a bit of filing and refining.
It's a pretty cool feeling when your tubes come together all because of your hard work and attention to detail, so for the time being I don't mind continuing to miter by hand. Maybe someday I'll find a milling machine that needs a home, but in the meantime I'll be filing away!
