Hello,
I purchased a Logan 200 lathe from the 1950s (?) that is in immaculate condition. It essentially looks new. One oddity is that the front or first ~2/3 of the threads on the head stock spindle are ground flat, with maybe 1/4 or so of their full depth remaining. The grind is so clean and uniform that I assumed this was intentional, perhaps to make threading of chucks easier, with the full threads at the rear to provide additional grip.
However I'm not seeing similarly-ground spindles in images on the web. Is this something that Logan did at some point? I'll add images when I can.
Thank you!
