With the subframe solidly clamped to the table and three cross tubes tacked into place (we used mild steel ER80S-D2 welding rod whenever welding DOM to chromoly) we moved onto the front framerails. You'll want to find a stationary point that you can always reference in order to make the chassis as square and uniform as possible. We used the centerline of the table, which gave us a point in every direction to start from and then built frames and jigs that were perfectly square and clamped into place to set tubing on before support tubes were built.
