Stands for Any Idiot -
The tech industry has devolved into one driven by glitzy soundbites that mean nothing, infested with a bunch of "Man Bun, Java Jockey, Pitiful Python Pirates" whom were told by their parents that STEM was better than being an archaeologist (or whatever line of work they really wanted to do [IF ANY]), being led around by their nose (and promises of BMW's and sapphire martinis at happy hour) by a clownfest of technically illiterate, greedy business monkeys.
This is getting more endemic across the tech arena in general.

Evan¡ what am I missing. If the tool is upside down behind the work, normal rotation would be called for¡ right?
?
David Robertson
YES DAVID you are correct. ?You use normal rotation with a rear tool upside down! ?I got that wrong.
?
An alternative is to use the parting tool in the normal tool post, upside down. In that case you run the motor backwards. It may be difficult to adjust the height of the cutting point. ?And problems with screw-on chucks getting unscrewed. I see Arthur Coe just posted that too.
?
And the backwards single point threading also requires the motor to run backwards with the tool upside down in the normal tool post. That way you cut away from the shoulder and don't have to stop threading abruptly. This is useful when you cannot disengage the half-nuts eg when cutting a metric thread on an imperial lathe or vice versa.

I do it upside down, in front of the work, with the motor running backwards (clockwise as you face the spindle).? Works great.

Re: A visit to a scale model steam locomotive factory in Colorado
I am in a tiny town called Strasburg, 36 miles (60km) east of Denver.? I was chatting to the camping ground staff about Goldmine Experience in Thames, and they told me that there is an engineering firm making scale model steam locomotives (about 19¡± gauge) just around the corner. Within walking distance.? It was 4 pm on Friday, but I ran over.? The 85 year-old owner (Marlin Uhrich) gave me a wonderful 2.5 hour tour of his private factory. ?He has all kinds of old manual machine tools (no CNC). He also has a foundry with a cupola furnace capable of melting 3 tons of cast iron. ?
?
I took loads of photos and talked about Goldmine Experience, when it suddenly dawned on me that he may be able to help with replacing the displacement oilers that were stolen from our steam engines. He said he has about 18 of them. I spotted two on the shelf and offered $50 each. He said he would take $75 each. This is a bit cheaper than the quote we had from a dealer in UK at 1250 pounds each plus shipping!? So I bought them both and will ship them from Tennessee to Thames later in May.

I've found parting to be much easier with a "T" shaped HSS blade, mounted with the minimum length of blade protruding out of the tool holder. It's worth the effort of modifying the tool holder to properly mount the blade.

I have had great success with a parting-off tool that takes a push-in insert (all metals). Always do it close to the chuck and never with a fixed steady or a tailstock centre.
