If you google Alex Wetmore he has a great blog about the basics of rack building. It's getting a little old now but still full of great info. Also, get a decent bender. I recently just bought a Rigid 400 series bender for 5/16 tubing. About to order some tubing and start. I need to finish the frame first.
