THREADING ON THE METAL LATHE WITHOUT A THREAD DIAL

Internal threading on My 16 inch Swing South Bend with no threading dial, or reversing switch.

[@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 👍

[@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.

[@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!

[@patrickmcevoy5262]

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

[@deangdmppajj4692]

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

[@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.

[@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!

[@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.

[@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.

[@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.

[@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

[@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.

[@oscardominguez6491]

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

[@sneakystaffie]

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

[@TomofAllTrades]

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

[@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.

[@danielkennedy1524]

Brilliant, excellent video, thanks

[@TerryTalton]

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

[@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.

[@erichope1103]

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

[@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 !!

[@kurtdietrich5421]

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

[@powaybob]

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

[@mfletch392]

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

[@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.

[@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.

[@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!

[@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!

[@falcfire3093]

Nice, exactly what I needed!

[@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

[@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

[@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.

[@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.

[@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!

[@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.

[@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.

[@rallymax2]

Great video. Thanks for making it.

[@sirlancair]

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

[@Blasulz1234]

this is infinitely useful!!!

[@RustyInventions-wz6ir]

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

[@frankfralick]

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

[@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.

[@TheDagda1000]

Interesting and instructional. Thanks for sharing.

[@bikerides]

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

[@MattysWorkshop]

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

[@MWSRD]

Very helpful and well explained thanks

[@nikocristi6810]

Awesome explained.Thank you!

[@keithsmith7278]

Thanks for sharing, that's brilliant

[@NOBOX7]

great video

[@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.

[@michaelrodriguez-fb8fr]

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

[@kandalfus]

you are the master thank you for sharing this Technic

[@jamespufflecock6466]

Great video, thank you!

[@pelleguess6499]

This will come in handy- Thanks

[@johannesengelbrecht4857]

Thank you, it is a great help.

[@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

[@davidgreen2442]

Well done great info

[@kingolafff7739]

nice video!you made my day:)

[@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.

[@mark8664]

Looks good, like you know what your doin.

[@sinkhole40]

Great tutorial!

[@robert1352]

Well done!

[@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.

[@caahacky]

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

[@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

[@waf3I]

beautiful !!!

[@68sweetnovember]

Excellent !!

[@craigtate5930]

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

[@darylkesler8470]

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

[@theflyingdutchman787]

Great!!! Thanks.

[@Capt1331]

Great Tip it will come in handy...

[@apx5777]

Brilliant

[@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?

[@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.

[@jeremygraham8282]

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

[@paulpannabecker9962]

Very Nice, Thanks!

[@junkmaster0174]

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

[@theessexhunter1305]

Very good

[@liyawei]

Good tip

[@guttormg1208]

Thanks, reall usefull!

[@DieselRamcharger]

Thats pretty clever!

[@heronvontremonia9975]

that will be useful, thanks

[@s.foostenveld29]

Clever !

[@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.

[@rickystone4137]

good job

[@charlesmcboy445]

brilliant!

[@plunder1956]

Wow - that car seems very close to your lathe.

[@Jackknifegyp]

Forgot to ask how you made the steel cutter. Did you weld carbide bits to the center, 180 degrees apart?

[@howardcalkins7765]

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

[@ANTHONYBRUNO03]

impressive

[@Luischurch]

Thanks a lot!!!!

[@KatyLynnWinery]

I am new to machining. What do you call the type of tool holder you have that holds a round cutter. I am only familiar with the one that holds square tooling. Thanks'

[@Trex1268]

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

[@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?

[@Nasedo375]

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

[@algae1000]

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

[@markhodson1945]

Damn clever

[@northotagogolf]

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