THREADING ON THE METAL LATHE WITHOUT A THREAD DIAL

[@DeseretRider]

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!

[@travwil2461951]

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.

[@patrickmcevoy5262]

I found this one of the best videos I ever seen thanks

[@gazork123]

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.

[@multicraftman]

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

[@backwardsmachining7526]

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 👍

[@stephenrose8188]

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

[@frankcire1439]

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!

[@deangdmppajj4692]

I have an old southbend without a threading dial. Your video is a great help. Thank you

[@FBPrepping]

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.

[@jodifu6274]

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.

[@colinwarner7762]

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.

[@rustypanels1917]

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.

[@sneakystaffie]

Very nicely done, so simple yet so effective. Well done champ :)

[@TheZachKat]

Awesome! Thanks for sharing this method. My '46 South Bend C is about as basic as it gets, and this is the way.

[@powaybob]

Nice! I "knew" this could be done. Good to see a clear demo.

[@gregcook9915]

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.

[@spannercrab4120]

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!

[@oscardominguez6491]

I had been looking for a tutorial like this, thank you so much for sharing.

[@danielelliott3659]

Pretty cool trick. Pretty nice old lathe too!

[@frankfralick]

Thanks for posting this. I just got a 16 with a missing thread dial and Google led me right to you!

[@TheGodsrighthandman]

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

[@Nasedo375]

LOL You are very welcome, you made my day... three months later.

[@Nasedo375]

You're welcome. It's always nice to make a "pretty" thread, but as long as it works... good show.

[@glenndavis2762]

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.

[@antoniotorchiarella6199]

The Gods Right-Hand Man

[@nevetslleksah]

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.

[@justanothercanuckian]

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!

[@bigbattenberg]

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.

[@spykespyke7099]

Very logical, very simple method! Thank you very much!!!

[@kingdom777866]

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 !!

[@erichope1103]

Great video for all that are missing the thread dial :) Thank's !

[@NOBOX7]

great video

[@Rolingmetal]

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.

[@MattysWorkshop]

Gday, great demonstration and it works great, thanks for sharing, cheers Matty

[@TerryTalton]

Thanks! Just finished repairing a Sheldon with no dial and needed to learn to work without one.

[@rederiver6974]

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.

[@kurtdietrich5421]

I have a very similar South Bend 13 x 40 lathe from 1923. Very cool. This method works really well.

[@RustyInventions-wz6ir]

Just found your channel and subscribed. Very nice work. Thanks

[@NSTRAPPERHUNTER]

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.

[@hakimmic]

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

[@michaelrodriguez-fb8fr]

this was very useful i have a hendey lathe and no threading dial. thanks for the tip

[@crossthreadaeroindustries8554]

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.

[@danielkennedy1524]

Brilliant, excellent video, thanks

[@dawfun]

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.

[@TomofAllTrades]

I can't wait to try this technique. Thanks for sharing, and the process seems intuitive.

[@craigtate5930]

Nice approach. I haven't seen this before. I too don't have a threading dial at the moment

[@rayst.2934]

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

[@diniz]

Great video! I was just about to do my face plate M34 DIN 800 thread and this video was just what i needed. Thanks!

[@Joeyardmaster40155]

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.

[@plunder1956]

Wow - that car seems very close to your lathe.

[@mfletch392]

Just what I've been looking for thank I'm going to try it on my colchester lathe from 1918-1919

[@bikerides]

Great instructional video. Really clear. I'm going to try that next time. Could be easier than trying to read the thread dial.

[@norwamoom]

Great idea! I enjoyed your video very much. I intend to do an internal thread pretty soon ant this will be a big help.

[@sirlancair]

awesome teaching. Very clear and helpful. Thank you !!

[@jeremygraham8282]

Great video. You just saved me $125 on a threading dial

[@Nasedo375]

Gosh... I wish I had some of the old time training.

[@MrTjmk]

I'm going to have to try this on my cheapo Chinese bench top lathe. My little bench top lathe does have a threading dial but, every time I've used that threading dial I've ended up with a cross-thread. No matter how slow the spindle is turning or how meticulous I am about taking the slack out of the lead screw, I always get the dreaded cross-threading.

[@iakkubczechino2825]

Thank you very much, I have just tried it but im still not sure about me cutting the thread because I have little space to disengage and go back. Also the thread needs to be cut into a very hard material and my tool is already dull, need to resharpen it. But I thank you very much.

[@MrSpeedysteve1]

Big thank you from me too! I'll be testing / using this method on my Southbend 9" to cut some big internal 16TPI threads.

[@shelby50411]

Nice video...li just bought an old logan 200 lathe that was missing thread dial....your technique appears to work and is free lol

[@davidbutel932]

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

[@falcfire3093]

Nice, exactly what I needed!

[@bigbattenberg]

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?

[@dihskursiv]

Would it not be possible to fabricate a thread dial and install it on your lathe? Perhaps a future video?

[@Nasedo375]

Yeah that would be a good one, but I need to make a part to let me thread a 14 inch faceplate, make a riser block to fit a 13 inch SB tailstock to my 16 inch SB, and a BUNCH of other stuff involving not just machining. I hope to be in a "FREE" environment and making some videos by Summer. I hear the middle class are leaving the Globalist Republic of Kalifornica in droves...and taking their money with them.

[@junkmaster0174]

Thank you, i will be trying this on my sb 15" O this weekend. Looks like yours may be an o series also?

[@Jackknifegyp]

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.

[@Blasulz1234]

this is infinitely useful!!!

[@darylkesler8470]

A positive stop on back side for carriage may help so wipers do not remove your marks. Pretty smart idea.

[@algae1000]

Very instructive! What is the I.D. on the workpiece for the 1 1/2" 8 tpi threads? Thanks.

[@Nasedo375]

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.

[@TheDagda1000]

Interesting and instructional. Thanks for sharing.

[@chrisstephens6673]

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.

[@northotagogolf]

Great idea - way to go for me! BTW, you sound very much like Kevin Costner.

[@donpeterson9282]

Very interesting. I will write a procedure for myself so I don't miss any steps in my shop log. This will enable a quick reference check. The great thing about my shop log is I also cross reference the video to the log if I need to review something. Can't wait to try this out as I have to build and adapter for my wood lathe for my Nova chuck. This will be a good metal lathe project to learn on while justifying the metal lathe cost to my beautiful project supervisor (e.g. Honey, guess how much I saved by making my own chuck adapter for my wood lathe!!! No, it didn't cost anything as I already had the correct tools for the job! LOL) Many thanks.

[@M1KEMEX]

Nice lathe. Oldies but goodies, huh?

[@courtneymullen9166]

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.

[@MWSRD]

Very helpful and well explained thanks

[@Tryin2FlyII]

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

[@rallymax2]

Great video. Thanks for making it.

[@oneandy2]

Mark One eyeball and sharpie analog encoding feedback system. Impressive. :D

[@johnnymossville]

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.

[@larrysmall3521]

Great video! Is there any way you can use a setup like this to cut metric threads since the thread dial can't be used?

[@michedmck]

Hey, Larry! This technique should work for any type of thread. Since it is really doing what the thread dial is usually telling you (that the headstock, leadscrew, and carriage are all aligned relative to one another), the type of thread should not matter in the least. Give it a try and let us all know.

[@rayfalcoa1955]

HelloNasedo375 nice video,thanks for sharing,'you

[@keithsmith7278]

Thanks for sharing, that's brilliant

[@t.d.mich.7064]

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.

[@pelleguess6499]

This will come in handy- Thanks

[@ronnieg6358]

I guess the thread is a 60 degree 'groove'. Why is the tool holder slide (whatever it's called) set at 29 1/2 degrees and not 30? You might have guessed I'm a greenhorn!

[@howardcalkins7765]

HOW TIGHT IS THE CAP SHOULD BE. IS THEIR A SPEC. ON THAT??

[@kandalfus]

you are the master thank you for sharing this Technic

[@Nasedo375]

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.

[@clemm17]

the multiple rule is any multiple of the lead screw will drop it in the same spot, where ever you drop the 1/2 nut. The only thing you need to worry about is taking the slop out. You dont need any marks. If the feed is set to 8 tpi with an 8 tpi lead screw, I dont think its possible to miss 8 tpi?

[@Nasedo375]

My lead screw is 6 TPI, how does that work? I guess I have to check it out, once I finish the job in the chuck. It's been there for two years, or so. Stuff has been going on.... sigh...

[@robert1352]

Well done!

[@nikocristi6810]

Awesome explained.Thank you!

[@Trex1268]

For an internal thread the cross feed goes at 29.5 deg in the opposite direction as an external thread?

[@Capt1331]

Great Tip it will come in handy...

[@kentrianda2201]

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?

[@sergio29552]

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

[@SkalabalaK6]

Why do you not reverse? Lathe a bit old? Nice video :)

[@johnnybgood42]

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 ..............:)

[@rickystone4137]

good job

[@davidgreen2442]

Well done great info

[@mark8664]

Looks good, like you know what your doin.

[@Nasedo375]

If you mean you got a South Bend 16 inch lathe, then you probably have learned many were not even drilled and tapped for the thread dial. Threading dials were optional. Was your lathe drilled and tapped?
