I like your lite humor. 😊 Great demo, I'll be trying it too. Thanks!!

superb, i think your the only machinist on KZfaq to explain bore sizes for a thread, if i could thumbs this up a hundred times i would

I've cut some threads manually by inserting the chuck key in the spindle and using it to rotate the work, but I've never seen a manual crank operation done like this on a motorized lathe. Neat.

7 minutes in and I'm learning so much from you! Glad I clicked on this and can't wait to learn more. I already know I must get a caliper clock, I need to turn an obsolete awesome set of bike cranks I have- now into machinery crank levers of sorts! And it's inspiring to be reminded of the joy of making threads that don't have to conform to any standards.

I've done this method quite a lot over the years - for some reason I often used a 26 TPI pitch whatever the dia. I too use a spindle handle a lot for screw cutting. Like those clock calipers. You have a great collection of measuring gear.

Thank you SO much for this invaluable tutorial Steve,my next turned project can now be multi-part without living in terror of the lathe!Brilliant,much obliged sir.🏆

I really enjoy your videos Steve! The indepth explanation you provide in your all your projects are superior and very rare to see for these types of videos. Thank you for taking the time to share your expertise, uncomplicated methods for the deferent type of machining practises. It really helps a great deal for hobbist like myself. Thanks

Thank you, this will be a great method for me. Not only am I a novice, but I also have a standard change-gear lathe, so there's no lovely gearbox levers to adjust on it. Changing gears really isn't that difficult, but it does take time adjusting backlash...not to mention the research I have to do to make sure I have the right gears in the right places :)

Steve,you make it look easy every time...cool video.

As follows the method I learned as an apprentice toolmaker and as shown on the Colchester Lathes training film. Set the top slide over to half the thread angle and set the cut depth using the top slide. Grind the tool with half the thread angle. Set the cross slide at 0 with the tool just touching the job. Move the tool away from the job using the cross slide. Wind the carriage back to clear the job, put the cut on using the top slide and return the cross slide to 0, engage the nut at the appropriate number.

Great idea

Agreat job and explanation, and the best thing is providing the links. I can't thank you enough. I pray to Allah that He bless you and grant you good health. Thanks a million.

I watch a lot of your videos and really appreciate the depth and the thought you put into them. I have a 1942 model f atlas and do a lot of work and use a lot of your ideas. thanks a bunch

This is a very interesting video! I was always weary of cutting threads on a lathe but this way it is really easy and safe to do. Thanks!

Enjoyed learning from you, keep up the good work

Thanks for posting this Steve. My threading tools and 10 spare inserts arrived yesterday, I bought the same set as yours from BG. I finally ran down the Zeus booklet and now the mystery of internal and external diameters for threading is solved, B.T.W I have also made the expanding mandrel modeled on yours for my mini lathe. Thank you so much for taking the time to do your postings they are much appreciated. Rob - from South Africa

Thank you, wonderful information.

Very nice method for cutting threads ! thank you for sharing your knowledge !

Great job of threading. The Myford lathe has some nice features. The threading handle is a great tool and I like the flat cross slide with all of the "T" slots. That would be a good feature on any lathe.

Another great video Steve.Love them.

Excellent. Thank you

That is fascinating. Great demonstration. Threading is on my list to master.

Great video with some excellent tips watched a few of yours now

all of them so nice I'm try to learn from you thanks sir

Thankyou have homemade lathe this will work perfectly for me ty

I cut left hand threads on the mini lathe by reversing the lead screw rotation on the back of the mini lathe and use your hand crank design. works real good!

Also the carbide inserts from China have improved considerably over the years. I find they last nearly as well as the more expensive branded ones. Also remember that it doesn't matter whether you use a metric or imperial insert for non standard threads, as long as you use the same type in both the external and internal thread tool for a particular component. Also when using a carbide inserts for screw-cutting there is no need to set the compound at any particular angle.

Just OUTSTANDING,,,,,will save this newbie a ton,,,

Your are the best,,,thanks for taking the time to set up the cameras giving us excellent coverage of your projects ..TW canada,s west coast

very nice video Steve,very well explained.....

Thanks for information

Awesome idea, I have a large 15" lathe but will try the crank. Dont know at 83 if i will be able to reach the handle and have enough strength to crank it. I will give it a try...

Hi Steve great video. The more I watch the more I learn from you. I also made a crank handle for my South Ben once I seen yours. Use it mostly with my tap and die set. And yes as a beginner I am terrified of crashing the tool trying to cut threads with the lathe but not now got a new way of learning it. And also I was able to make a indexing plate after talking to you out of a sprocket I found at my local farm store. Just had to bore the center out to fit the back of my chuck and bolted it onto the back .It has 30 positions not 24 could not find one 6 inches in that count. Works great. Keep up the videos.

This is very safe to avoid crashes and not break tools. I like your idea. Besides making nice threads, you get a little exercise. Thank you for this demonstration.

Bloody marvelous! Nice show.

APU..................excellent..................more than.........Thank you so much for your time. David from"Downunder"

Thank you Steve for showing this, it takes the stress out of thread cutting.

Outstanding

Awesome vid. Very clever. Thanks for sharing

Great tip on thread cutting. Thank you

That was brilliant. I am totally new to a lot of this. Thankyou for all your advice on types of tools very skilled and interesting.

Amother brilliant video (as usual). Dom in Belfast.

This is brilliant, I am going to have to give this a try. Many thanks and greetings from Africa.

Thank you so much for this video. It has made me more confident to attempt threading my projects.

Thank you for sharing this outstanding method ! I was totally unaware of this but recognize the versatility and reliability it gives.

Another great video Steve, I had never thought of thread cutting with the manual crank method, excellent idea :)

Hi Steve. I have just made a hand crank and indexing hub, as per your earlier vid, many thanks for making it so clear and simple. In this video, you are turning a metric 24mm thread, and I am keen to try it for myself. My mini lathe ( almost certainly similar to yours) only has change gears for up to a 2mm pitch, but 24 mm calls for a 3mm pitch. As an inexperienced machinist (me) that is, does it really matter what pitch I set? Or should I just set the maximum I can and just use the correct 60 deg indexable tool? I’m not cutting to match another internal thread, just something else I will also cut. So I’m guessing that to a certain degree anyway, pitch will not matter.

Most interesting & useful & crash free which suits me greatly given I once crashed my ml7 & broke the half nut making me very wary of power feed. Also very interesting how you move back in time to before Mr. Whitworth when there were many thread sizes & make what suits your job. Makes sense as I often struggle to make things to be a standard size when often there is no real need. Nice thread cutting tooling too. Thanks for sharing.

Excellent, thank you. I have never attempted screw cutting in the lathe, always been nervous about it but your technique seems very simple and straightforward. Given me confidence to give it a try. 👍

This is the best thread cutting video I have seen, this will help me learn thread cutting on my ML4 Many thanks

I really enjoy your videos Steve

Enjoyed this and subscribed. Hope you do many more..!!!

The problem with lathe and mill etc work is standardisation, all thread every hole must be made, so everybody can reproduce holes a tread and other machining work. I am glad that at least one person who steps from the standardisation ladder and just produced what HÉ likes, thank you!

I like the crank...gives you more control

Very Nice job

An example and instructions from the mind of a practicle engineer, makes perfect sense to the amatuer like me

Thank you

Thank u for the idea Any link for the quick tool post changer ?

I'd love to work out/see how this idea could be adapted for the Chinese mini lathe. Once I install a decent pillar drill and mill there won't be close to enough space in my small back garden workshop for a second late!

This was very useful information. Thank you for sharing your insight and experience via this video; this will prove very useful. Those are nice pellet canisters. I am sorry that they are not full cartridge canisters.

Thought you were crazy at first but it makes a lot of sense. The older I get the slower my reflexes are so this looks interesting.

Have not done any thread cutting yet but this is the method I will be using. Thank you for the video, very clearly explained.

I tried your method today . I wanted yo cut an internsl thread on new crankcase I am making for a small diesel engine. The thread needed was 32 tpi. Getting the gears right on my very old Myford lathe , I think its an early lm 2 , was the hardest part. I couldn't fit a handle soused the large pulley wheel and turned the thread quite easily. Thanks again for the video.

learning a lot from your videos, thanks for posting!

well done!

Another well explained video Steve, I use my winding handle on my lathe for threadcutting too, another reason I clear the tool on the return stroke is if there's a slight amount of backlash between the leadscrew & the half nuts the tool will bind on the work & make a wider cut than needed,I've oddtimes "forgotten" to remove the handle after finishing & turning another job & the lathe gives an unpleasant shake!!! he he.

Excellent. I really like the hand crank idea. I must look back through your videos to find the instructions for making the crank.

I never thought of making a handle to turn the lathe. Excellent .

Brilliant, never seen anyone post such an easy way to make (in my case fine pitch camera filter threads) on short homemade adapters for telescope and lens fittings, some with only 3 to 5 mm long work pieces. The conventional way is very tricky to say the least! Thanks for sharing, I have joined your channel. Used have an Myford Super 7 back in the 1960's before I emigrated to Tasmania 😃 land of sunshine and clear skies for astronomy.😁

very nicely done Steve never thought about doing it that way thanks for sharing

Thank you.

Well done!

hi sir your all videos so nice n very useful

Congratulations, is very simple your method. I like. Thanks.

As a complete beginner this was very useful, I'm trying to buy the holders/cutters and was wondering is the cutters in the round bar holder the reverse of the A60 or the same just a different holder. Sorry if its a silly question! Oh and I looked down below, just don't see the links.

Thanks that well be very handy!

The hand crank is so simple and controllable, great. Peter

Great idea , especially for the inexperienced like myself . I like the bike crank for the handle.

Great method, thanks.

all the best to you Steve and yours from John in Texas

That has to be the best explanation on how to thread I have ever seen! And thanks for the description of the book.

great info thanks for posting

Great.

brilliant and thankyou for this, im not scared to do this anymore and actually cant wait to try!! awesome spindel mandrel idea as i have a ml7 too, game changer video for me this is thankyou steve !!

Hi Steve, great video, have see you use it before but great to have it explained. I also have an ml7 built in about '65 in really good condition, was wondering if you would consider doing a video walk through of your lathe and its modifications and use of the Myford lathe, back gear etc. there doesn't seem to be much on Utube on the basic operations of these lathes. Once again thanks for the work you put into your videos. Cheers from Australia Raymond

Can I use my Imperial Boxford Lathe to cut a Metric thread?

Very useful. Joss in Cork.

Never seen this before and what a great idea for those who may not have the kit for professional operations and for working in the smaller lathes.

Hello - that looks quite easy. Not sure but I've seen other machinists angle the compound to match the thread angle and then feed in on that rather than the cross-slide. I think the theory is that it just cuts on one side of the tool then.

Superb video again, especialy for someone who like the tricks from a specialist! One question about the Thread Dial Indicator, can you explain how it is used ( in the video i don't see the detail, perhaps it's easy but for a novice...)

Very nice. Can't wait to try this.

Hello Steve - do you provide modelmaking services. I need to have made a small pulley for a Leslie speaker cabinet to get the vibrato speed correct. Thands, Andy.

Yet another great lesson from Steve. The man to watch for learning. Thanks Steve.

impressive thanks for sharing

Very good demonstration on threading. Really like the technique of hand powered threading. I am thinking you forgot to add the tool holder and insert numbers. If you could still do that it would be much appreciated. Thank you for your effort doing these videos.

thanks for sharing some idea... great job.

Okay now I gotta go and build a hand crank for my lathe.... Then I can use it during a power outage too =)

Superb instruction.please make more .

Parabéns ! Muito bom !

Great video Thankyou
