trouble threading bolts
i just successfully threaded my first bolt, only to discover i was
threading left hand threads. aaargh!
how can i thread right hand threads while starting the thread at the
bolthead?
how can i hold the bolthead with the tailstock and center the end of
the bolt with a live centerin the spindle?
i'm thinking about grinding a tool to cut threads upside down.
