I have been cutting threads a while and I have never seen or thought of the one wire method. Thanks Joe.

One-wire measurements. Of course! That, sir, is brilliant.

Another "Amazing!!!" class Professor Pie. I am so thankful to you for doing this. I'm in school at 46 years old in a wheelchair to boot and I have learned more from how you teach than from my instructors. My time on my lathe is far more productive. I will need to turn A & B threads class 3 like your showing that will need to withstand high pressures. I'm green but learning much faster with your help. God Bless you brother!

I like what I just saw! (as you asked it). Your videos are top notch and will serve many, many machinists for many years to come. They have certainly helped me.

Thanks for the video, Joe. Every time I watch your channel, I learn something! Thanks for sharing your expertise.

thanks joe, that was a tricky topic but you explained it well and didn't dumb it down.

There are a ton of videos on threading but now i finally understand how to do it right. Thanks for the tip from the last video with the inverted tool, I will never thread the old way again. So much less stress!!

Very good information, Joe. Thanks for taking time to explain how to make our work much better (more precision) and I think easier.

Well done Joe! This one goes in the favorite list for future reference.

Looking forward to B class threading videos. I am making a plug gauge and watched this video again. I started using the wrong set of numbers and remembered you saying "Don't use A class for a plug gauge. thanks for saving my butt. Thanks for all your videos Joe. Big Fan!

I'm fairly new to this and already you have saved me several hours with your various videos. With all the thousands of views your videos have I wonder how many hours you have saved all the people watching? maybe a million? maybe more? IDK but THANK YOU VERY MUCH!

Thank's Joe Teaching is a lot of work for sure.I got a lot out of it though and thoroughly enjoy your teaching style .You are definitely one of the best on U Tube who makes a complex subject achievable for an average guy

Thank You Joe!! Just got my wires the other day and was looking for a detailed description on how to use them. I did a search for you and your thread vids and found this one. I am headed out to the shop to try the one wire procedure on a part with 1-5/8"x16 thread for multiple parts. I am new at this stuff at almost 70yrs old and grateful for your knowledge. I love the way you tackle things!!

Joe, After watching the video and attempting to do the measurements, they did not come out correctly. So I watched the video again and took notes and was able to make it work! Thank you for the explanation. I then decided I needed a cheat note to be able to do this 2 months down the road. I came up with some drawings/worksheets that help me see it and the numbers needed, for the next time. I would be happy to share them with you if you like. Not sure how I could get them to you, but if you are interested, let me know. Thanks again for all the videos that share your knowledge!!

Joe your advice on threading has been a big help I can't thank you enough

great video as always. For a future episode I would love to see design and use of a plug gauge for verifying internal threads. keep up the awesome work!

That was a class-3 explanation, Joe. It might clearer to some to say that the pitch diameter is that diameter where the width of the thread is equal to the width of the space between two threads. You said that in a different way, I think. A very valuable lesson.

hey prof joe that video rates two thumbs up. probably the most complete discussion on thread classes i've ever seen. i really liked your one wire technique. i may retire my collection of thread nuts now. my thread nuts were all made from hex stock using taps. i was told by an old timer years ago that if you checked the thread class on the tap you could get away with this.but then all our customers were in the steel mill where we worked. can't wait to try the one wire technique. thanks joe.

Your instructional videos are great. Just getting into running threads on my new lathe and you've already saved me a lot of heartache.

Thanks for the education, Joe. I have long wondered why three gages, when one seemed to provide the same information, as you so aptly demonstrated. Nice to finally put that quandary to rest.

I'm glad you mentioned running in reverse when sanding the burrs off the thread. I can't tell you how many times I've taken that operation for granted and gotten my finger sucked down into the hole. Fortunately I still have all my digits.

Watched this video when it first came out and now back again for a refresher because I have a critical to me cyl. rod threading job for my sons backhoe and want to increase my threading skills. Thank you, Ed

Had to come back for a refresher after your latest video. Worth every minute! Thanks for making these educational videos!

Best practical explanation I have seen! Thanks for sharing.

You videos are fantastic, your method of teaching is spot on. Thank you for your time.

Thank you Joe. That is the best thread video I have seen. Well presented. I learned a lot and some of it was still over my head. Thank you

Best explanations on threads I have watched.

Thanks Joe! Your tips are always useful for all of us out there in the REAL world.

great video Joe. on a subject that is usually glossed over very briefly. Fred , U.K.

Excellent description. Thank you Joe !

I¨m currently threading 2 x16 un on aluminum. Been some years that I´ve done some threading. Your vid really helped. Keep up the great work Master Joe!

I work for the US Navy as a civilian machinist, and I NEVER thought of using one wire!!! But as soon as you started explaining I knew exactly where you were going with it, and I thought DUH!!! what an idiot I have been all these years...HOWEVER, the machine shop work lead and supervisors all say IT HAS TO BE DONE THE WAY WE HAVE ALWAYS DONE IT and I doubt they would accept the single wire method...even if I PROVED it to be accurate. It is f=definitely going to be a method I use for myself and then let the work lead use all three wires to verify for me when they do a first part check...tee hee hee!!! Thanks Joe!!! I LOVE your tips and hints and tricks...been watching you for years...

My third time watching this one .Great videos.Some of the best on the machinist channel.Thanks again for the hard work Joe

This is the one I was looking for! Thank you for taking the time to post this. I just got my first set of wires and was a little unclear on the add and constant value usage. This cleared it up for me. I am a maintenance "machinist". I make parts for our factory machines, but I am certainly not a journeyman level by any means. The guy I replaced (due to retirement) would always make an internal thread in something to gauge the external on the part. That's fine if you are making your own mated pieces, but not always so good if you need to mate to an externally sourced piece. In all fairness, he taught me a lot, but had his own way. Anything else just wouldn't work. I've been binging your videos now that I am on my own and have the shop to myself. Thank you for continuing my education.

Joe Am the Master trying to teach the Apprentice. The Master knows no more than the apprentice. Studied Machinery Handbook - lots of info -- good stuff for sure. Watched all the videos I can find from Gurus. The goal is to cut a lathe chuck adapter plate with 1.5 x 8 TPI. All of my practice so far has been just that - practice - on stuff I can scrap. Yup made my mistakes there. Have concluded that I must cut a plug gage to get it right. THANK YOU for telling me to cut the gage to the specifications for the class B (internal) the light came on. Dan Bentler Seattle

Thanks, Joe! Merry Christmas.

Thanks for your video Joe. I just took a new job today measuring Precision threads for a company that makes ring gauges and plugs gauges. It's my first time doing this kind of work and I'm still pretty lost so I looked up videos to help me learn. I learned a couple of things from your video and I appreciate it. Thanks again

Thanks to your insistence on accuracy I bought a set of Pee Dee thread measuring wires, acme thread pitch gauge and an acme screw thread tool gauge for a project I'm working on.

Knew I'd seen the one wire method at some point ! Tried this today on a m42x0.75 with 0.18 wires... and a conversion chart for metric The difference between the 3 wire method and one wire method, one involved grease on the wires swearing cursing and general frustration the other required 10 seconds of my time and both values were spot on ! What a time saver for the future !

Thanks for all the great videos!

Just found this video, great discussion clearing up details of measuring threads, thanks.

You didn't give any detail that isn't in the machinery's handbook, you just offered it in a way that made it llogical, understandable and rememberable. Never stick your finger down that hole, no matter how tempting!! use a stickwith the abrasive attached! Thanks for another excellent offering. Stuart

Once again, an outstanding training video. !!!

Joe I am a big fan, really enjoy your great presentations. The way that I approached the 3 wire balancing act is to put an O-ring on top and another on the bottom. I start off with a readily available metric O-ring assortment kit and pick 2 that just feel right. For the 3/4 - 10, this is an O-ring with an ID = 11.8 mm and OD = 16.6 mm.

Your videos are the best. Thank You

Joe, this is gold, thank you.

Thank you for explaining how to use the constant with the thread gauge wires. I bought my wires a few months ago, but could not figure out how that chart that came with them was supposed to be used. now it is all clear! luckily my first real threading jobs were one offs on tools I made for my self; no worry about hitting a standard for that session; next time I can.

Finally somebody who is as fanatic about threads as me. I have been threading upside down & backwards for 40 years. Scoop out the chip pan before handling the wires. I use grease to hold the wires in place because I only have two hands. When making more than one or two parts that need thread wires I hold them together in the right position with masking tape. Back in 1991 on my first ship I had to use iron bailing wire to measure threads because I didn't bring my wires with me, had to calculate the measurement over the wires using right angle trig. Do you remember when the Machinerys Handbook did not have tables for metric thread dimensions. I had to get my first copies of metric thread charts from the Landis Threading Handbook. Fisher Tool, Hawthorne California (Pee Dee) will sell individual wires to replace lost wires.

Awesome tutorial thanks Joe! ...Next, can you show us how to turn progressive pitch threads. The idea being - as the part is tightened the male part (ie: bolt) elongates under tension thereby disengaging most of the threads that would have had contact under no tension or torque. The result being only a few (front or leading) threads of engagement carry majority of the load, while the trailing threads due to the part being stretched may not even engage at all...and so to speak "hang in the air." This may not be critical if only pulling forces are placed on say - a bolt. But if lateral forces are placed on a really long bolt such as a lever arm threaded into a hole, the front engaging threads could act as a fulcrum point since the trailing threads have no contact. A crude example would be - Think of your lever for enaging the half nut, has only side forces. Full thread engagement would prevent it from loosening since that would reduce wiggling if only the first 3 threads are actually touching while the part keeps getting forced side to side. Now multiply this event times 100 or even 10,000 vibrating at a harmonic frequency and since....everything is under tension---while wiggling around...you see what can happen to the few threads which do have engagement. - Or just the part keeps loosening. One way I imagine would be to lap the threads in but.... ---Is a progressive pitch thread possible on a Manual Lathe, or only CNC? Thanks for any thoughts you have on this.

Very good lesson ! Thank you !

Invaluable. Many thanks.

Very informative, thanks.

Thanks, Joe!

:) now my wire sets contain 2 spares of each size :) lol . thanks a lot for the good information and videos. rgds michael, berlin, germany

Hey Joe I had to cut some 1/2x13 , 5/16x18, 3/8,x24 threads today on the lathe for a job at home on for some special bolts and shafts use your techniques on threading ,and use the machinery handbook to get the head diameter and use the wires to Measure the pitch diameter. It was a class 2A thread. After I got finish with each bolt and shaft everything went together smooth and with no wiggle on the threads. I have to cuts some class 2B but I have to make a class 2B external thread on a plug gage so I can measure the internal threads. Thanks again for sharing information

Thanks Joe, much useful information here.

Thank you, your videos are excellent

Great vid, keep up the great content.

thanks joe i no its an old show but it sure helped me out

3rd time I've watched this (slow learner.) This time after arguing with another (amateur) machinist about the single wire method you show. Being a long way from a real machinist doesn't mean I can't try to get good results. When I got my (Chinese) wire set, I measured each one to see how accurate they were, better than I had expected. Since the wires are going into a V any deviation in diameter is going to have a bigger affect on the final measurement. Fumbling with 3 wires, even with the yuck grease method was a challenge for me. Thanks for the help.

Advanced Innovations University - AIU Awesome stuff, Sir! Thanks for sharing

Awesome as always!

Most useful Joe -- always something new to learn or -- remind me of something long forgotten!! Single wire approach sure is easy when thinking about it. :) Good point re the B class internals - very valid.

Good info Joe! Thanks!

Thanks for the video....very interesting!

Hey Joe you raised more questions on gauge diameter and pitch diameter, please run some numbers on making a gauge for your 1" 8 pitch thread so we can understand the what you mean. Thanks, Joe

Joe Pie, you are THE MAN!

Hey Joe, Really liking the video series. Years ago I used an interchangeable anvil thread Mic. that was made by Tesa. It was an awesome tool. Not sure if they make it any more. But thought I would share that with you.

got tonnes out of it Joe. great as always

Great lesson, thanks.

Thanks,joe a very good explanation

Joe. interesting talk on threading like the back story on the board Always found if I knew the why the rest was easy. Merry Christmas and all the best for 17 from Down Under Will

Joe, I have been a machinist for over 30 years and I have cut numerous threads. I too love my wires. the only problem i see measuring over one wire is its not a true pitch diameter. If you cut your part .005 under b4 threading , wouldnt you have to allow for 1/2 of that? Its easy to get a burr on a thread that would be misleading also. Sure 3 wires are hard to hold , but ive used a ball of putty, grease , and rubber bands or o rings to help hold my wires. I have plug gauges ive made that are double lead left hand stub acme. made using wires. I do enjoy your videos, keep up the great work!

outstanding explanation, outstanding knowledge. couldnt hit subscribe fast enough

This is really useful. Could you do something similar on gear geometry?

So glad I watched this video again today. I am about to make a plug guage to fit a 32mm x 2.5mm pitch internal thread to a depth of 100mm I have to cut, your warning about making the plug thread to class B thread pitch diameter will mean I get it the correct size. ( hopefully first time )

Keep the good videos coming Joe, thx a lot! I'm a selfe thought (almost) gunsmith here in Sweden and watch your videos with great interest! I fit barrels to both hunting and competition rifles and try to keep decent tolerances on my jobs. Your videos keep adding ideas an knowledge! :-) /Stefan in a cooold northern Sweden.

Damn good, Joe !!!

Great Joe, do not think that there is anymore to say about threading, very deep...:):)

joe, i would like to see a video that gets into odd threads, multi-start threads, modules, diametrical pitches, maybe even worldwide threads that we see in the states occasionally (bsw,bsf,bsp,bspt) it seems as if no one has any videos with these odd pitches. few people can explain a diametrical pitch, much less cut it on a lathe. (including myself)

Fun to watch and learn👍👍👍👍👍👍👍👍👍

We just had a discussion on this topic last month. I showed the machinist at work the instructions on how to measure the external threads using the three wires per the machinery handbook and discovered that they were out of tolerance. CNC guys trust their CAM packages a little to much... Simple old school ways taught them a lesson that day.

Awesome! Thanks!

Spot on Captain

Hi Joe, thanks again for efforts, I just ordered a toolholder to try your upside down threading method!

Thank you, again

Hi, joe. I have to measure large acme threads to check if it is worn and documents my findings. In years past we used a go- no go test set. It has to do with % of life left on the threads it's not a deal breaker but it would help me get a good repeatable valve if I used the 1 wire and hardened dowel pin? Great video. Thanks for sharing

Great video thanks again

Good info Joe, thanks. Regards, Duck

Merry Christmas Joe 3.142, and your family.

Great Joe just Great.

Hi" your passion for this is outstanding" great teacher to boot, but still friends have not got it. So" can you go over it again using the mic, & the machinist hand book, showing each "STEP" with the charts from your wires too. On the white board this is perfect. This is a BIG subject that most do with a wing & a prayer. I know others on utub have covered it,, BUT you have a style that's second to none, & passion, please break it down step x step take your time 10 videos if need be, but it will be the most viewed threading on the tube. I promise. Regards Rob U.K.

highly recommended for those new thread enthusiasts.

nice explanation.

Great info on threading Joe can you show some id threading going away from chuck like you did on od?

Great thanks

I've just watched this video,great detail joe,and it has convinced me to invest in some wires. Just a quick question,are these only suitable for 60 degree threads or can they be used on 55 degree bsw threads? Rgds Matt

Hi Joe! I like your video content, and I have been watching your videos for quite some time. I have a question about internal threading. When I make a plug gage for an internal thread, do I machine the OD to the major diameter of the A class or to the minor diameter of the B class? Thank you for your instructional video I have learned a lot from them.

Joe, this was a fantastic video.. I am a total armature so I learned a lot. I have a set of wire but haven't used them yet. I will the next time. One thing I thought of is when you use a single wire for your "Y" value, your error tolerance of the measuring equipment will double. That might be a interesting topic for a future video. Covering %of reading vs % of full scale. Also I noticed the dive flag on your tee shirt. You make diving equipment? I use to do a lot of recreational diving in my younger days. Don't think my ears will let me do it any more. Take care and ignore all the trolls that know everything there is to know. Al, Michigan

Hi Joe, I am really learning a lot from your videos. Thank you so much. I have a question that may or may not be worthy of video but maybe you can at least point me in the right direction. I am trying to use the Machinist's Handbook to figure out a thread problem. I want to thread a hole in a plate, approximately 3/4" in diameter that I will run a screw into to support a specific load, say 1000 pounds. How do I determine the minimum material type and thickness of the plate and TPI to support that load. Thanks again, Russell
