Excellent John. That's a perfect explanation of the top-slide angle for threading
Very impressed with the re-registration of the chuck
Finishing cuts are always a sod (at least that's the way I find them ;) ) I was taught to give the tool a light wipe with a fine stone prior to the final cut to clear any tiny bits of swarf sticking to the cutting edge (I use a diamond lap for carbide inserts). Don't be afraid to polish the job - sometimes it's the only way to get a finish.
BTW The Hardinge spindle lock has 6 positions which are very handy for quick indexing 2 or 3 radial positions. Does the Boxford have more than one lock position?
