Don't take offense but they aren't really close to the "industrial grade" ones I've run. An American Pacemaker, LeBlond NFL, Cincinnati tray top, Mori Seiki, Okuma LS, Monarch C, Meuser and dozens more are significantly more robust. I've run all but one of those (the Mori Seiki) and they are in different class altogether. Yours is often found in the "toolroom" of some maintenance departments of big companies as a support shop, so it's what I might consider a "commercial grade" but not something often found in everyday production.
I fully agree the Logan is not in the class of the larger lathes you cite as I too have run Pacemakers, Cincinnati tray tops, Monarchs, Sidney's, and other 16" & larger lathes including a Lodge & Shippley 24 X 120 (36 with the gap bed out).
However we also used Logans on board ship & industry when it was appropriate and they can hold the same tolerances. Other than schools the only place I ran SB's was in a sweat shop. BTW, 14" Jets are another story, junk from the beginning. Brand new and required main motor replacements, coolant motor replacements and the paint fell off like it had been applied over the top of oil/grease all in less than 6 months.
