OK, Thanks everybody, Got almost more answers that I needed. I did take the crank off and rotate it 90 degrees on spindle to see that it is the crank, not spindle that is off. Have not tried the pencil as a "truing stand"to see if just one or all crank arms are off center. Big chain ring looked flat when I set it on table. Chain rings need replacing anyway.

I'll try straightening this up later if I need it on another bike project; just ordered a used Hollowtech Ultegra triple crank and threaded external BB off Ebay.
