Didn't know of that technique,  interesting.
Another way which I use is to set four jaw chuck jaw no. 1 horizontally and toward you then very lightly touch a turning tool against the side of the part.  Note the reading on the cross slide vernier.  Move the tool back and away using the saddle and turn the chuck 180 degrees.  Bring the saddle and tool back and again lightly touch the part.  Note the second reading.  Halfway between the two readings is the centre,  on that axis.  Adjust and tighten jaws 1 and 3 until the tool lightly touching the part reads that halfway number,   on both sides of the part.   Repeat for jaws 2 and 4 and the centre of the part now lies on the Lathe axis.
That process also avoids any inaccuracies placing the centre pop.   Can use it on both square and round parts,   but not assymetric ones unless you can account for the assymetry.

40 years? it looks brand new. My 2 year old lathe looks more like 40, and yep I also have the same tool height adjuster, also thanks to Joe he is a legend

Thank you for making this video. I thoroughly enjoyed watching you make that tool and watching how you cared for that nice lathe you have. No wonder it looks so good after all these years. I hope you have children or grandchildren who are interested in machining, if not, maybe a young boy or girl in your community who needs a kind person to take an interest in them and teach them some of what you know. You are an excellent teacher with a gentle, calm demeanor. I purchased a mini lathe a few months back, a 7” x 14” with a little less than 1/2 HP. It’s been very fun, but very underpowered. I’ve ordered a new lathe, 12” x 36” with 1.5 HP. I’m looking forward to making this tool on that lathe. I hope you keep making videos. Best Wishes, Wayne

Nice work Steve 👍

Wow, I can’t believe that lathe is 49 years old.. it looks like it was just Un-crated and assembled ! Amazing caretaker you are !

Great video. I liked how you took us all on a journey of creating something useful.

Thanks for idea.  I’ll be making one. My first video I’ve seen of yours and you have definitely earned a new subscriber 👍👍😎👍👍

My first video of yours. It definitely impressed me! I’ll be around for a while. Thank you for the education.

Excellent work

You have a great channel, I like how you explain what you are doing.

what a wonderful workshop!

Your lathe looks more-or-less brand new, you clearly look after your machines - Subscribed.

I absolutely love machining 304, it finishes so beautifully with no need to file,polish, or sand.
It doesn’t like fine or light cuts so much but it looks so good when you hit the correct speeds and feeds with a good quality insert.
This is the first time I’ve seen your channel and I can already tell I’m going fit right in here. I’m not into woodworking but I love manual machining and learning !

Nicely done sir !!

nice work and a very useful and good looking tool 😁👍

love it, good work!

nice vid format for a first !
keep them coming please.

cheers ben.

The 4 jaw vid got a fresh sub for you👍👌🇦🇺

Only took me right till then to understand what you were making. Very cool :)

Brilliant !.   Love to see a video about keeping the lathe clean.
