Brian,

If memory serve correct the annealing temp for 6061 is above 900
degrees.  Weld supply shops have temp sticks (like crayon) that melts at
lable temperatures.  hard to get the whole piece to that temp but you
may be able to do problem spots.

Did you use 6061 for a specific reason?  Mant parts made with the
english wheel are from 3003 which is dead soft and very easy to form
compared to 6061 or 5052.  It is also weldable by gas flame although I
still prefere TIG.
