2nd run with torch, messier, still trying to understand where to point the flame and how to successfully bond the two entities

Next step: hit everything with grinding wheel and start over, fixing to try what greenville said: put beads in the corners, then try solid beads half of each line to distribute heat, give big heat to the cast iron skillet, then push the rod into the area, melt the bronze, let it cool solid

New attempt: point the flame on the cast iron skillet, push the bronze rod exactly where you want the bead to form until it liquifies, move down the line forming a bigger bead and waiting longer for the bronze to melt, make the bead form at the intersection of the two entities big enough to encompass the 1/4 steel patch...
