Finally, I got this stud out by welding a 13mm nut on the end of it and the
heat was enough to let it turn.  It is a long a large thread.  Now I have
asked Boston Bob to send me some replacements.
I have checked the "archives" for the last six month and did not find any
good write up within that period.  There was one to suggest to heat the bolt
for five minutes with a propane torch at the base.
Anyway, it is out and I'm glad.
Thanks for all who were concerned and tried to help.
