I enjoyed it greatly, but I did not understand what you did.

i

He removed a tool changer/toolpost turret from a very large CNC lathe,
took it to a shop to repair a cracked casting properly and then
reassembled it. 9" spindle bore, probably threading oil well drill
string pipe fittings or something. Probably 100HP spindle. Big MF.

OK, I got it, thanks. I usually think that if it cracked once, it will
crack again. But it was a fun project.

When welds are done right they are often stronger than the base
material. Trying to apply a rule to fixing all cracks that are welded
is the wrong approach.
