YES, I got in a hurry and made a mistake near the end of this video when I was demonstrating the setup for cutting an inside thread. Thank you to the viewers who pointed this mistake out in a constructive or humorous way. To those viewers who thought it necessary to include an insult, well I hope that made you feel better. Some comments have been hid just to prevent a pissing contest from developing. Ya'll take care & I'll see you on the next video.

Well, I'm glad that I finally got to see your video after what I assume is three years. I certainly hope that you haven't stopped making videos. I learned a lot from this one, and have subscribed. Being an Electronics Engineer (retired) by trade, I do understand trig inside and out and have used it in my little shop many times in setting up my lathe, but actually I like your method much better and I look forward to hearing more from you. Thanks for sharing your knowledge. Plato once said: The beauty of style and Grace and harmony and good rhythm depend on simplicity.

Thank you for showing, Mr. Lee for those that can’t go one day without given a derogatory response, is because they are frustrated by the ones that will show them a better, simple way of finding a good way to complete the job at hand. FYI, when I went to Mechanical Engineering School, and any one student did not grasp the subject correctly, the professor will find a way to explain it well, your method was explained to us the same way you did in your video, with a big difference, we did not have a new lathe like yours, our was a South Bend original model 9” C, donated by the USA to the School. Thank you Mr. Lee have a nice and safe day.

Very well done, thank you, I wish I had seen this yesterday, it would have saved me an hour of mental confusion before I got the angle correct for a taper cut.

What a terrific idea! It lead me to try something a little different. I chucked a 1/2inch rod. Then aligned the top slide using my old 30/60/90 triangle from drafting class. I put a 1-2-3 block against the rod, and set it on the slide. Bingo!

I’m a newbie and I caught your mistake on the second setup, I read through the comments to verify and I was correct. The one thing that I would have liked to see on the second setup was for you to use a boring bar with a thread cutting insert on it because the way the tool holder was positioned, you couldn’t have mounted a boring bar. I did get what you were saying right away on your first setup enough to realize the mistake, so that’s a good trick I’ll remember. Thanks

Thanks for the video, your time and effort are always appreciated!

wonderful Lee, always love watching your videos, and I always learn something great.....cheers from Florida, Paul

Wow! Thank you! So simple I don't know why I've never seen this method if setting the compound.

G’day Lee that’s a good way of setting the compound, well explained. Cheers Peter

Interesting, I'll keep this method in mind. Thanks Lee

Agree with your method Lee, you just make a blue on the second half as soon as you released the tool holder block. I will use the method. I normally put a bar between centres, but that only works if there isn't a job set up. Thanks mate Cheers.

Great alternative method . Cheers .

I’ve chased both left and right handed threads , internal and external and never had to swing the compound around.

Cool work sir 👏👍

Good method.

Looking at the potentiometer, eh, the protractor… I have heard people slip a lot worse and creating lots of laughters. It's nice You are human Lee!.

You already have a perfectly good scale for setting your compound to 30 degrees in both directions for both internal and external threads, just think about it, would PM have made a machine that needed this much faffing about to do a basic thread cutting job?

Lee excellent idea but you should review the procedure you made a small error . :) just as a thought how is the dial fixed on the cross slid or is it one piece you might be able to swing it round so you can line up the mark's either way you swing the top slide just a thought . :)

Ah Lee, your a tricky son of a gun! 👏

At the minute 9:55 you are wrong, you should made the last adjustment by loosen the two nuts instead of loosen the quick change tool post

I like the method...simple/smart.....bozo got ya....as the error at the end is a great brain tease for a viewer with experience and a train wreck for a newbie....

I like your method and appreciate your video attempt to help others but as stated by others and yourself about the mistake in your 2nd setup. Why don't you remove the video and post a correct one?

Здравствуйте! Резцедержатель у Вас великолепный! Можно ссылку ,где такой приобрести можно?!

I got it at about 8 min. in.

Big blunder at 9:48... yep you adjusted the tool post not the compound...DOH

Please Mr take off your finger rings. I have a neighbour that lost one finger during working in the shop.

LOL, all was good, until the last procedure for inside thread cutting. You got a little too cocky, and screwed up your procedure....

If you can’t do a little simple trig you have no business trying to be a machinist. An indicator against the tail stock quill or chuck face is by far the quickest and most accurate method to adjust the compound angle. Just use sine or cosine.
