There was a problem with the frame ...
When you clamped the bare frame in the jig and looked at it straight on from the front to the rear, it looked like the front end and bottom bracket were twisted to one side.
The rear forks were SOLIDLY welded into place, so what could I do about it? I thought about it, and thought about it. Kind of a slow thinker. And PROCRASTINATED, because I was so upset with the frame. Finally I cut a piece of stock main tubing about 2" long. Clamped it sideways in the vise and started cutting strips out of the length ... creating quite a gap ... until it would squeeze tightly together and just barely slide into a piece of main tubing stock.
Then I took my hacksaw and cut perpendicular across the main tube of the frame about 3" up from the rear forks. Using a round file, I filed in little half-round chunks out of the edge of the main tube. Slid the insert into the main tube and tack welded it into place. Then I slid the insert into the rear section ... put it in the jig ... and made sure the entire frame flowed straightly from front to back ... before finishing welding it all back together.
