Aspiring hobbyist here, and this concern might not even matter, because I'm building my own jig out of 80/20, so it's not the most precise thing in the world...
I got some centering cones machined for me on the cheap. Is using cones to secure the bottom bracket shell a bad idea? I imagine now that the start of the shell threads would cause the alignment to be slightly off.
Not worried about damaging the threads as the cones are aluminum and the BB is steel.
