New lathe arriving!

Making chips yet?

I faced the end of a piece of brass that I had laying around.
Went fine given the lack of appropriate bit.
I’m focused on cleaning all the built up sawdust/grease off it at the moment. It’s seriously gunned up.

If you’re threading without a thread dial or some non standard tpi (metric) then you have to leave the half nuts engaged and then use reverse to run back to the start of the thread.

Its can be faster to thread this way anyway.
You do need to make sure the chuck is on tight
AND let the motor STOP before you switch into reverse.

Seems to me, any operation attempted in reverse will tend to cause the chuck or drive plate to unscrew from the spindle. Or am I missing something here?

You don't "need to use" a chuck or plate in these circumstances. collets are driven by friction between the collet & internal taper of the headstock & a center to center setup can be driven with a dog-leg driver tightened onto the dead center or headstock spindle (careful not to damage threads).
 
I believe many collets have a draw bar (tube actually) at the other end so no worries about direction you spin.

I never used old thread on lathe - there are videos online that show how you can mitigate chuck undoing itself issue.
 
It looks like the bed still has the scraping marks, that does make it low time use, nice find. I bought my SM 9" from the same place that has the SB you were looking at, the delivery charges looked cheap but to me there were to many issues. It looks more like a parts machine than a user. Glad you waited and found a nicer unit.
 
That would be them. We took the legs off and then slide the lathe into the back of my truck. They were pretty easy to deal with and although I didn't pay full asking for it I didn't steal it either. Is see the other SM 9" that they sold is up for sale in on CL.
