A very handy tip, thanks for posting! I want to try this for myself. BTW, a tip handed down to me by a long-deceased toolmaker I had the honor of working with was, whatever the pitch of the leadscrew is, you can cut multiples of it without using a thread dial. I was a maintenance machinist in a local rolling mill until last winter, and one of our lathes was a 1943 Monarch with a leadscrew of 2 TPI. All even numbered threads could be cut without the threading dial.
I just did this a few weeks back. Like an idiot I didn't check the scratch pass and I ended up turning a 14tpi thread instead of 8 but live and learn. Awesome video and great info. Thanks 👍
Finally---something that works. I've tried a hundred times using different 'methods' found on the internet video's---but never, NEVER, was able to get my thread on a single track---Until now. THANK YOU Nasedo 375----Your instruction is worth it's weight in gold! Thank You---thank you----THANK YOU!
Seems like the help offered on youtube by true people sharing information and not trying to sell it is a great thing. Thanks for another way to solve a problem.
Great teaching video, straightforward, no gimmicks. good teaching skill. thank you very much for your time and trouble, as soon as I get my little lathe up and running, I will try this great method. Colin UK.
This is brilliant. If you own an old or used lathe, the threading dial is probably long gone and a replacement is difficult to find and expensive. I've been threading by using a reversing motor and driving the carriage back using the half-nuts. Can't wait to try this out!
You're a great instructor! Not everyone who does so, does it well. I have an old Dalton Six type B-4, made in 1918, and this is exactly how it's done, except I have to manually swap out gears.
GREAT video. Excellent quality, your explanation are simple but just what one needs to know. I am a beginner in this, and I understood everything you said. Obviously you have quite a bit of experience doing this. Thanks for taking the time to share it.
Guess what. I just got a new Baileigh Lathe and it does not have a thread dial. I sure thought it had one when I ordered it. I thought I was screwed cause I have lots of threading projects I want to do. The Chinese manual says to leave the screw ingaged and reverse it but I don't like to do that. I'm going to try your method. Sure glad you made the video. Thanks. Donald
Thank you, this is really helpful. I have a very old lathe with no threading dial and i find threading to be slow and stressful. This is going to help a lot.
Fantastic video and explanation of the process. I was thinking of ways to make a cheap thread dial, when I saw your video. Problem solved. Thank You so much for sharing this.
I think you done a very good job with this video, not easy holding a camera in one hand, while operating a lathe with the other.. and watching it dont crash !!
Thanks for the tip. I have a very old Hendey cone head lathe with out a thread dial. Though I can reverse the apron without disengaging the half nuts the marks can be used for reference. George
There's a lot of crap on youtube; and you would have to look far and wide to find someone to dispute that, but when it comes to quality you're up there with the best of them. Well done!
Marking the spindle and leadscrew with a sharpie is genius. It visualizes the fact that they meet up on the same point after a defined number of revolutions.
This is great thank you. I have a Metric Boxford BUD and trying to find a metric dial indicator for it is near impossible so knowing how to do this without the dial gauge is invaluable.
Interesting technique. Normally I cut thread without disengaging the half-nuts, but If I ever need to thread a long piece I hope I remember this. Thanks for showing.
Hi Mr. Nasedo. From a half a world away thanks for the great video. This should come in handy on my old South Bend 7.5" lathe that doesn't have a threading dial. The few threads that I've cut I just backed out and reversed the motor next time I cut a thread I'll try this . >Joe Baltimore MD. USA.
I figured this method out on my own with a *lot* of trial and error; I certainly could have used this tutorial a couple of years ago! My 1910 Seneca Falls Star lathe has a weird 9tpi lead screw, so my only option is to use these reference marks to make a thread.
Thanks for the video, it has given me some confidence as i don't have a reversing switch or a thread dial. When backing out of the piece with the cross slide the returning to zero ready for putting on the next cut with the compound, what effect does backlash in the cross slide screw have? [I have a LOT of backlash]. Thanks
Great video! The special boring bar tool holder/ tool post you made looks great too, very sturdy. I suppose two of the hexagon head screws are for rotational alignment of the tool, indexing on a flat? They might be fighting the clamping action of the whole block, or do you back them off before final tightening?
Thank you. Thankyou, thankyou, thankyou! Fucking THANK YOU! :) I bought a 72 year old Myford MF74 (a rare old girl) and it has no TDI and little chance of finding one. Today, Thanks to You, I cut my first ever Thread - 3/8 x 20TPI. It's a bit rough if I'm honest with myself but it's a Thread and it works. Once more, Thank You xXx
Thanks a bunch - I have a Daewoo 20 x 60 with the leadscrew being a ballscrew and no thread dial. I can now use this technique for the balance of threads where you need to leave the half nut engaged.
Thanks very much for that , the gear that runs on my lead screw is missing out of thread dial on my ss1000 lathe and i cant get any one who is prepared to make one . But at least i can do some threading now . Cheers ..............:)
Pretty cool idea! I think I seen another guy do this or use this method he had digital read outs that's all he used its the same idea as yours I think? I know NOTHING about this stuff but I m going to defiantly watch and learn try and get started
excellent work I was looking for a video like this one because my lathe is a Logan 9B and it docent have tread dialer to so it those help me that video thanks body
I wanna talk about compound angle as for metric it is really 29.5 cuz metric thread angle is 60 so half of that less a little is okay but imperial is different angle it is 55 degrees half of it is 27. so the compound with imperial should be 27 degrees. i tried that and it is gave me good result.thanks for sharing this video.
Hmmm...I was trying to set the compound so that the tool would be advanced into the leading edge of the thread. I will look up the modified flank infeed method.
if youre using the modified flank infeed method your compound should be in the opposite. direction, this current setup is correct for external right hand threading.
Is it possible to do finer threads ---in the 28-36 tpi using this method? Very inventive though, even if only rough threads (NPI?) can be done. Thx for simplifying what most have said in discouraging the use of a lathe to make threads, in favor of a boring bar.
I would find a half nut attachment for the lathe. They are out there at a reasonable price. I would think that any lathe with a quick change gear box, should have come with one or at least mounting holes for it.
NEW WEST WALES is what I call the land bordering the Pacific ocean from Mexico in the south to Oregon in the north. Technically it doesn't exist, but it should. I live in a country founded by English colonists, and established on ideals espoused by John Locke and others. I am of English/Welsh descent and I feel my country and myself have everything in common with Great Britain... everything but the language. God save the Queen and keep the Constitution of these United States safe.
Oh the good old days, that's the way an old friend of mine was taught back in the late 1940's, he was always going on about using chalk marks when threading. Guess they didn't have Sharpies back then.
Great info but question from a rookie . .. why did you use the compound at 29.5° angle to increase thread depth each pass and not just use the cross slide?

Great Tip! and well filmed and explained. Not a method I have seen before but will use in the future. Thanks a million.
Steve, Kent, England
Very nicely done, so simple yet so effective.
Well done champ :)
Nice! I "knew" this could be done. Good to see a clear demo.
I found this one of the best videos I ever seen thanks
I can't wait to try this technique. Thanks for sharing, and the process seems intuitive.
Thank you, this is really helpful. I have a very old lathe with no threading dial and i find threading to be slow and stressful. This is going to help a lot.

Thanks man. I have a 1940s south bend 9A without a thread dial, and I've been wondering about threading. Off to the shop to try this out!
I have a very similar South Bend 13 x 40 lathe from 1923. Very cool. This method works really well.
Thanks for the tip. I have a very old Hendey cone head lathe with out a thread dial.
Though I can reverse the apron without disengaging the half nuts the marks can be used for reference.

Great find, I am making a 1 1/2 - 8 spindle guard at the moment for a 10" Atlas. Good video to take the mystery out of threading.
Thanks! Just finished repairing a Sheldon with no dial and needed to learn to work without one.
There's a lot of crap on youtube; and you would have to look far and wide to find someone to dispute that, but when it comes to quality you're up there with the best of them. Well done!

Thanks for posting this. I just got a 16 with a missing thread dial and Google led me right to you!
I had been looking for a tutorial like this, thank you so much for sharing.
I like the technique. Even though I have a threading dial on all my lathes, I am going to give it a try. Thanks for making the video.
This is great thank you. I have a Metric Boxford BUD and trying to find a metric dial indicator for it is near impossible so knowing how to do this without the dial gauge is invaluable.
Just what I've been looking for thank I'm going to try it on my colchester lathe from 1918-1919
Brilliant, excellent video, thanks
Great idea! I enjoyed your video very much. I intend to do an internal thread pretty soon ant this will be a big help.
Great video! I was just about to do my face plate M34 DIN 800 thread and this video was just what i needed. Thanks!
Great video for all that are missing the thread dial :) Thank's !
Big thank you from me too! I'll be testing / using this method on my Southbend 9" to cut some big internal 16TPI threads.
Just found your channel and subscribed. Very nice work. Thanks
I have an old R. McDougall lathe that is missing its threading dial so I'll be using this method. Thanks for sharing and all the best.
Interesting technique. Normally I cut thread without disengaging the half-nuts, but If I ever need to thread a long piece I hope I remember this. Thanks for showing.
this was very useful i have a hendey lathe and no threading dial. thanks for the tip
Very logical, very simple method! Thank you very much!!!
Hi Mr. Nasedo. From a half a world away thanks for the great video.
This should come in handy on my old South Bend 7.5" lathe
that doesn't have a threading dial.
The few threads that I've cut I just backed out and reversed the motor next
time I cut a thread I'll try this . >Joe Baltimore MD. USA.
Gday, great demonstration and it works great, thanks for sharing, cheers Matty
Nice video...li just bought an old logan 200 lathe that was missing thread dial....your technique appears to work and is free lol
great video
I was wondering if there isn't another way to cut threads without a dial my machine does not have one I'm so glad I ran across this video thanks a lot
Great instructional video. Really clear. I'm going to try that next time. Could be easier than trying to read the thread dial.
awesome teaching. Very clear and helpful. Thank you !!
Nice, exactly what I needed!
Nice approach. I haven't seen this before. I too don't have a threading dial at the moment
Thanks for sharing, that's brilliant
I figured this method out on my own with a *lot* of trial and error; I certainly could have used this tutorial a couple of years ago! My 1910 Seneca Falls Star lathe has a weird 9tpi lead screw, so my only option is to use these reference marks to make a thread.

Thanks for that. Will try it on my Myford ML2.

this is infinitely useful!!!
Thank you, i will be trying this on my sb 15" O this weekend. Looks like yours may be an o series also?
A positive stop on back side for carriage may help so wipers do not remove your marks.
Pretty smart idea.
That atlas is a 6" with a quick change gearbox? I didn't know they made one!
This is a great tip you've come up with. Looks like it works perfectly.
Thank you. Thankyou, thankyou, thankyou! Fucking THANK YOU! :)
I bought a 72 year old Myford MF74 (a rare old girl) and it has no TDI and little chance of finding one. Today, Thanks to You, I cut my first ever Thread - 3/8 x 20TPI. It's a bit rough if I'm honest with myself but it's a Thread and it works.
Once more, Thank You xXx
LOL You are very welcome, you made my day... three months later.
You're welcome. It's always nice to make a "pretty" thread, but as long as it works... good show.
Thanks a bunch - I have a Daewoo 20 x 60 with the leadscrew being a ballscrew and no thread dial. I can now use this technique for the balance of threads where you need to leave the half nut engaged.
The Gods Right-Hand Man
This will come in handy- Thanks
Well done!
Thanks very much for that , the gear that runs on my lead screw is missing out of thread dial on my ss1000 lathe and i cant get any one who is prepared to make one .
But at least i can do some threading now .
Cheers ..............:)
you are the master thank you for sharing this Technic
Gosh... I wish I had some of the old time training.
Great video. You just saved me $125 on a threading dial
Pretty cool idea! I think I seen another guy do this or use this method he had digital read outs that's all he used its the same idea as yours I think? I know NOTHING about this stuff but I m going to defiantly watch and learn try and get started
Very helpful and well explained thanks
Very instructive! What is the I.D. on the workpiece for the 1 1/2" 8 tpi threads? Thanks.
Looks good, like you know what your doin.
Awesome explained.Thank you!
Great video, thank you!
Nice video. I've never worked on a lathe, so it's still unclear how to set the machine up to cut various sized threads.
Great tutorial!
excellent work I was looking for a video like this one because my lathe is a Logan 9B and it docent have tread dialer to so it those help me that video thanks body
Well done great info

Great Tip it will come in handy...
HelloNasedo375
nice video,thanks for sharing,'you
Oh the good old days, that's the way an old friend of mine was taught back in the late 1940's, he was always going on about using chalk marks when threading. Guess they didn't have Sharpies back then.
Forgot to ask how you made the steel cutter. Did you weld carbide bits to the center, 180 degrees apart?
beautiful !!!
Excellent !!
Mark One eyeball and sharpie analog encoding feedback system. Impressive. :D
Brilliant
Nice lathe. Oldies but goodies, huh?
impressive
For an internal thread the cross feed goes at 29.5 deg in the opposite direction as an external thread?
good job
Great info but question from a rookie . .. why did you use the compound at 29.5° angle to increase thread depth each pass and not just use the cross slide?
