I suspect he occasionally had to use a torch to straighten out a little warpage, but overall his consistency and balance side-to-side was all that it took. It also helped that the fit was very good and consistent. Obviously if one tube had a large gap it would pull differently than a tube with a perfect gap.

There's a time lapse video of a guy welding up a fabricated frame for a tri-5 Chevy.
Good stuff. The music is cool but it gets annoying after a few mins. Also, I hope you don't get seizures from flashing lights.
