So I really want to put together a nice road bike frame. I already know what to buy tubewise, but what will I need tool wise? Can you get by without a jig? What is an inexpensive torch solution? I will be working with lugs, so how should I practice? Is brazing kind of like soldering with a torch? I can't find too much info on how to braze lugs on the Internet. Can you guys help me out?
