HI All

LLoyd you may be right about the tool holders, and I've examined the inserts am they look identical and the way, one of the the inserts fit in the holder, I'd have to have the holder fixed in the tool post at an odd angle.

Bubba I've got a few versions of Mach3 to test with (things changed over time in the software) and the one on the lathe is an older version. so I will test with that version at some stage.

here is a pic of the tool holders.

Dave,
If the holders are mirror-images of one-another, but the actual inserts are not, then you do have a left-hand threading tool, but they didn't give you any left-hand inserts!

I have and use both, so I'm pretty familiar with their looks and their setup.  What you describe sure sounds like a right-hand (exterior) threading tool in a left-hand (interior) threading holder!

I went back and had a look at the original invoice for the tools, and you can clearly see that the RH tool that I was sent is a Turning tool and not a threading tool (they are clearly different). Roll Eyes

I decided to do a quick test of the turret to see how well it would cut, so I turned a 19 mm rod down to 11.75 and then threaded it to M12 x 1.75.

Went very well, As I didn't have the stepper motor connected I did the tool changes "Fred Flinstone Style" by hand and pressed cycle start to continue on after the tool change was done.

On the battery front, I friend gave me four 18650's and a charger, so I now seriously have to look at how to squeeze that stuff into the turret.
