...I am fairly confident that my first frame (road frame) will turn out ride-able...
Yeah, let us know how that works out...
I was pretty confident too. So I built it with NOS 531 from the 60s, and Nervex lugs. Now that I can
actually build rideable frames, I very much wish I had those bits back. I should have started with the cheapest tubing and lugs I could find. Hopefully you are more competent than I was.
