Q1: How would you suggest to remove rod?
Q2: If it is decided to weld a big honkin' nut to the end of the rod
to facilitate application of absurdly high torque values, what method
of welding would you suggest?
Q3: What method of welding would minimize total heat into rod?
Then kew kindly for your assistance.
