Help - how to change leadscrew gear position on 101 6x18

Robert, it worked perfectly. I feel a little silly now, it being so simple, hah! In my defense, though - the previous owner never threaded on the lathe for the 20-some-odd years he had it, so the spacer and the pinned piece looked like they were solid. A pair of vise-grips popped it off lickety-split, now it just slides on and off... so... problem solved! Thanks a bunch.
 
Pat,

I was hoping that would turn out to be the case.

If you haven't already, be sure that you read and follow the brief installation, setup and leveling instructions in the manual. Including bolting the stand securely to the floor. It's my opinion that Atlas included all of that as part of the machine design.

Yep, I will look at that when I get the chance... I have chatter problems every so often, and that may be part of the issue. The lathe sits on a wooden cabinet/dresser thing on a wooden floor, not bolted down to anything... but considering, it's not bad for an at-least-60-year-old lathe!
 
Is the lathe bed at least bolted to the cabinet? If so, how thick is the cabinet top? Should be a minimum of 2" (1-3/4") solid or built-up hardwood.

Nope. :S It's exactly the same as the previous owner had it for a long time, pretty much. Just sitting on the cabinet. The top is... oh... 3/4" thick... I've thought about making a different table for it. Robert, you might've given me a bit of a kick-start.

Correction - it is bolted to a steel table top, somewhere around 3/4" thick. That's sitting on the cabinet.

The previous owner is the instructor for the machining course I just graduated from, I figured he had it mounted suitably, but... his abilities have come into question...
 
OK, The steel plate should also be attached to the cabinet top (probably is, I guess).

If that tabletop is 'office desk' construction, it may be simply 2 sheets of 18 or 20 gauge sheet steel with a honeycomb core. Those kinds of desktops can be fairly stiff, but the question then becomes "How do the bolts secure to the table?". Sheet metal screws catching only the top sheet, or bolts that pass through and try to crush the honeycomb?
 
No, the plate isn't attached to the table. Not sure how the steel piece is constructed, but it appears solid around the perimeter. I think the bottom is recessed a bit in the middle. The lathe itself is held to the plate via bolts, I believe. Not sure how, whether it's a bolt and nut or threaded into the steel... but that just sits on the top of the cabinet. Like I said, that's how the previous owner had it.

I am thinking about making a new table for it, though. I'll have to look into the cost of a couple 2x4s, I do believe.
