1948 Pontiac seat frame.
Break is precisely at a factory weld. Can only get to about 50-60% of
the tubing. Have acetylene, MIG and TIG. Lousy at TIG.
Best way to reinforce joint? 1/4"x1/8" splines?
Form a partial sleeve (wrap while sleeve red hot) around area?
Slide solid steel bar into joint an weld the junction?
Thanks! All advice appreciated.
