Nah, as the NC State basketball player said, we are ambitious. We can do most things both ways.
Another leftie here.
I do a fair bit of reverse threading like you are describing, just be careful, if you are using a screw on chuck, it can come loose and cause big problems. I can do it on one lathe but not (or won't ) on my old Craftsman for that reason. I won't do internal threads any other way if possible. It's not the most fun but for really difficult internal threads (and some outside ones) you can make a crank handle for the lathe and turn it by hand. Takes a while but it gives you ultimate control. there is a video on youtube somewhere of a guy doing it.

Being left-handed requires one to adapt to a pretty much completely right-handed world. Sure, there are specialty items made for lefties, but they aren't (or weren't) commonplace.
I learned how to use scissors in the early 1950s. I doubt that leftie scissors were available, so I learned to use righty with my right hand. Some kids used them lefty but upside down, but that was too awkward. I also learned to swing a bat righty, play golf righty, drive a stick shift (all controls are in a right-handed configuration), learned how to use power tools lefty without accidentally engaging the "ON" lock, etc.
There are benefits. I can easily manage right or left drive cars on either side of the road, and use hand tools with either hand. Not a hammer. But I'm incapable of competently driving a nail with a hammer with either hand...

Since this is a metric thread, the half-nut must remain engaged throughout the threading operation. I used a hard stop for the carriage, and just ran the chuck back in by hand for the last bit. My chuck is bolted on, so no worries about it spinning off! |

Try brushing your teeth with the opposite hand; it is very, very difficult.

Best thing I had being left handed was when I fly fished a lot. I kept 2 identical reels on me, one wound for each hand. When one arm got tired casting, I swapped reels and kept going.
GRRRRRRR silly meter threads. The only thing worse is Whitworth

I had a 1959 Austin Healy 100-6 back in the day. Totally cool design, beautiful body, but like the Porsche bathtub cars, a PITA to own.
It had Whitworth threads, which are real pain in the butt. That wasn't the only liability: it had side draft (draught) carbs, Lucas (prince of darkness) electrical components, and everything leaked oil.
Oddly, British cars of the early days are another case of upside-down and backwards.

I like the metric system. So easy. Base 10 v base 12 is a no brainer, imo. Why can't a lathe have a metering system like the imperial ones do?

The metric ones do....you just have to buy it. |

I hear you. I've ever seen a metric metered threading system in a mini lathe. I've never seen a metric thread metering system on ANY lathe. You must be referring to lathes that are well beyond the reach of the average home machinist?

I just bought an unused 7" x 14" mini lathe on craigslist for $200. I got a bunch of tooling as well. I spent the afternoon cleaning and adjusting, but have not got it right as of yet. It should work out well. It is a metric lathe, and I might buy the parts to make it imperial with an indicator.
I might keep this one, or trade out/swap parts to make the lathe I want.
Time will tell!

Nope. I need to face up to the fact I don't need anything better than what I have. This one is bigger, but quality control is not great. I spent hours on it and will sell it. I should make a few $$ on it, for my labor.
The guy I got this from has a much better MicroLux mill, and a ton of tooling that I'm going to buy to replace my CentralMachinery mill. It has a expensive motor feed adapter.
I'll sell my mini mill to recoup some $$.
Booyah!

I picked up the mill and the stuff yesterday. He also gave me a single lip grinder for end mills. I didn't need it so I sold it on eBay. It sold almost immediately. I guess I should have asked for more money!
