Metric threads on pm1236

I’m at work, so my last post about skimming made it sound like I don’t pay attention to any of your posts. I meant I skim through YouTube videos. I have done all of the things you guys have told me here. The cutting metric threads with imperial lead screw is the key there, but I couldn’t recall how to explain that. I do have the fishtail gauge as well.

The lathe here is a Birmingham 13x40 with an 8tpi inch lead screw.

Ya, I tried it with the thread dial like doing standard threads and it wouldn’t work. It wasn’t until someone told me to leave the half nut engaged for metric threads. It worked after I left it engaged.
It works engaging and disengaging on the same number for standard threads fine, but not on metric. I need to watch all the videos you guys have posted. I have seen bits and pieces of all of them, but I have a bad habit of skimming.

your not following, when you stop, you put the lathe in reverse, and re-engage backward on the same number.
IT WORKS... you are picking up the lead screw at the same spot.

Im not very photogenic, so I don't keep videos up long. I assumed that after a week, anyone interested had seen it, so I deleted it.

Sorry. I’m in school for engineering, working at least fifty hours a week and trying to raise a family. Sometimes I have to wait a week to get on and read about this stuff.
 
No prob.

Are you pretty confident you got the jist of the method?

If not, I'm more than happy to do another video tomorrow.

Which engineering discipline? I went for mechanical engineering technology.

I still haven’t watched your video, but I get the jist of it.

Initially I was interested in electrical, now I’m thinking mechanical. My job is requiring me to work 50 plus hours a week, so I can only do two classes a semester and it’s hard to learn calculus When I only get to spend the time in class on it and maybe 4-6 hours of studying a week.

I shouldn’t say I’m in engineering yet cause I’m still doing all of the pre-requisite math, but you know how that goes and how much work it is.

I am also thinking about computer science. Working in a family business family would rather me run a machine for very little money than get my engineering degree and do something better. I’m not getting any breaks to focus on school unfortunately, so I’m not sure what I’m going to do. I’m In calc 2 and have a 70 percent going into the final and working way too much to study at all. I will take it again, and pass no problem, but I won’t be able to do that when I go to get my bachelors in engineering.

Im jealous, I wish I would have gone to school when I was younger rather than start working. Do you get to work in your field?

I just realized you are engineering technology. Do you wish that you went for mechanical engineering, or are you happy with engineering technology? That is my fallback if I can’t find a way to pay for it while reducing hours at work, or if I can’t cut it, which may be the case.

I've never worked in the field. I got the Mech Engineering Technology education, while halfway through a Law Enforcement career, to make use of some employer tuition assistance programs.

I just use the education to perpetuate my hobbies. I occasionally make money designing and building one-off machines, molds, stuff like that for businesses on my own time.

Engineering Technology required math up to Diff-EQ, plenty of physics, but only a semester each of engineering mechanics, thermodynamics and mechanical design.

But it also added in a semester each of electricity and magnetism, electronics design, drafting, drafting with AutoCAD and Inventor, and cutting tool design.

Also, practical lab courses covering CNC programming, Turning and Milling, and Cutting Tool design. Honestly, it wasn't a chore at all. I enjoyed it, and had fun taking all the classes.
I did most of them online, but with proctored exams at the end of each semester from a local testing service. Except for the resident lab classes. Had to take vacation time for those.

It was fun, but I just did it out of boredom, since at the time I graduated, I was already 12 years into a career. That was 6 years ago.

Once I retire, I'll use that education and start some kind of business to keep myself from getting too bored in retirement
