Parting made easy

[Paulc]

Many may already know this but I tried a new way ( for me anyway) of parting off a part.
I remembered seeing a YouTube video of someone parting off by having the parting tool upside down and then running the lathe spindle in reverse so I decided to give it a try.
What a difference! Cut thru smoothly, no chatter, no digging in.
This will definitely be my preferred method.

That will work OK so long as the chuck is not held on a threaded spindle and tries to undo itself !!

My prefered method is have the parting tool upside down at the rear of the spindle and run it in the normal direction.

Curious why it makes a difference - is it counter-acting some flex in the carriage or headstock? The tool itself is oriented to the part the same, right?

Yes, straight in from the front. Possibly the carriage and or cross slide is stiffer in a downward direction??
