Hmm ... I'm not sure whether the noise will be another problem.
I guess that it depends on whether his downstairs neighbors are deaf. :-)

@#$%!

Here we go again. I was zeroing in on a 9" Logan before the noise issue
came up.

Is this a genral problem with Logans more than others?


No -- it depends on the work you are doing. But any workpiece
out of balance will transfer energy to the floor through the feet --
either of the lathe or the table on which you mount the lathe, depending
on whether it comes with a stand or not.

Nope. Ok, fromthatprevious post it seemed as though Logans were just
generally more noisy lathes. But as long as that's not the case...


The noise which matters to you is what is conducted through the
feet to the floor -- unless you have it close to a wall shared with
another apartment.

Obviously swapping out the motor is way out of the question.


Huh? The motor simply provides the power, and assuming that it
is properly balanced (including the pulley), it will generate less noise
than the actual work being done on the lathe. Light cuts at the right
speeds will be quiet, wrong speeds or too heavy a cut will lead to
chatter, and that will transfer through the floor to downstairs.


I wa thinking that the motor and the specific matellurgical properties
of the gears made the lathe noiseir than others. But again, wince what
you mentioned applies to all lathes, then no problem.


The connection from the motor to the rest of the lathe is
normally V-belts, or flat belts on a really old lathe. The gears are
mostly in the thread drive from the spindle -- at least in anything
which you are likely to get up the stairs.

(The Logan
I was thinking about doesn't ahve quick change gears either, so perhaps
this is for the best).


Quick change is convenient -- but it adds to the weight. The
little Atlas (6x18) never came with quick-change. Larger ones had
quick-change as an option.


Even though it wasn't spec, perhaps there is a way to add QC gears to
the Logan in the future?(It's a Logan model 400).


I don't know. Check Logan's web site. See whether a related
machine (same size) was available with a quick-change gearbox. If so,
expect to have to change the leadscrew, and probably some other gearing
in the headstock when you make the change. Or get another machine with
the right setup, and sell this one.

Enjoy,
DoN.
