Please explain your “brazing” process as it applies to cast aluminum.
My Tig experience is only moderate. There are guys on here who obviously have done this for a living.
One of those guys may happen upon this thread and quash your warping fears in the hands of a journeyman TIG welder, using a nice ridged fixture to hold things in alignment.
