One last tip to consider if replacing tangs.
On my boat
, all the metal tangs were first welded to a 3/8" thick steel
plate about 3" wide x 4" long. This allowed me to have the tangs deep welded to the plate into a slot I had burned there for the tang, so the tang was welded to the plate on top and bottom.
This also allowed me to give the tang an appropriate angle on the plate to allow for a near as dammit perfect alignment with each particular stay or shroud
. The corners and edges of the plate had rounded edges.
Then the entire plate was welded to the deck
Doing it this way offers the possibility of welding the tang "plate" to the deck
, instead of just the tang. The plate perimeter offers a strong connection as it as it around the tang ( the tang already being welded to the plate) and may allow welding in an area which offers better "weldability" for want of a better word.
