So I've been working with my old Logan 825 10" lathe with the
6" 3-jaw chuck that it had on it when I picket it up 30 years ago.
I broke down this week and bought a new 3-jaw and 4-jaw for it.
I was getting ready to fit the "Fully Machined Threaded Backing Plates"
up to the plane back chucks and when I checked the plates for run out
and found they both, (one for each chuck) run out .009"-.010".
The nose of the Logan lathe spindle is on size i.e., 1.4985" but
the boss in the back of he adapter plates is already bored out
to 1.515"-1.516"
I'm kind of stuck as to what to do. I can mount up the backing
plate and turn it to fit it's new chuck but I'm afraid it's not
going to repeat when I change chucks if it's locating on the
thread only.
Any ideas????
