 Hi All,    I am in the process of machining thru hull 
fittings (316L ss) that will have 1/2" shafts running through them to turn 
valves, turn rudders, and other functions as well, drop weight, and possibly 
move trim ballast ;-)     .  The fittings that I am 
machining at the moment are 1 1/4" od  with the 1/2" id ( for the 
shaft)  is that 1 1/4"  a big enough chunk of steel to be welded 
through 1/4" A516 70   or should that OD be larger for some 
reason? 
Thank You 
Brian Cox
