Hi Joe, It was a pleasure visiting with you last week and getting the shop tour. My father was very impressed with the machines, tools, layout, cleanliness, products and most important, you. He really enjoyed talking with you. It's been many years since he was in a shop, guessing almost 50 years. I wanted to surprise him with the visit. On the 4 hour trip back home, all he talked about was you and the shop. For the next several days he referenced you here and there. I have been trying for about 10 years to move his shop from the cramped garage to a much larger room in the back of the house. After seeing your shop, now he wants to move. :) So our next project is to get that room ready. More lighting, more electrical outlets, level out the floor, AC, and so on. We plan to make another trip to visit the machine shop supply (Candy store) some time. Again thank you for your hospitality and looking forward to seeing you again. BTW, the products you make are incredible and VERY well made.
Joe , I am a beginner at 65, love the time I spend with my lathe. Just wanted to say thanks for your generosity in sharing your knowledge and experience
You have changed the way I look at threading! I do a lot of thread cutting on pipe and shafts (internal, external, left and right) and I have been using your method of threading away from the spindle since I saw your first video on it. Huge help for a younger guy trying to get comfortable in his first real machinist job! Thanks so much! -Louis
Hey Joe, Thanks for showing this again, I went out to shop after you showed this the first time and will never go back to the old way of threading again! My thoughts and prayers go out to the DeCarlo Family and to you for being a true friend! Best Regards, Ray
I have a suggestion. Do not apologize for taking a break in your video releases. We are busy so we don't notice. When you apologize it's a momentary downer. It's the positives that made us subscribe and make learning from you a fun experience.
Joe, I'm a recently retired machinist. I worked in the trade for 35 years, mostly job shops in my younger days. Spent the last 10 years or so doing field machining mostly in power plants. I just discovered your RUclips site recently. I really enjoy watching you demonstrate some of the finer points of the trade. Keep on posting, please.
Joe, I lost my business partner out of Rockwall,TX about 2005 from pancreatic cancer and my heart goes out to his family and you as his friend. I know it's been some time now but God Bless you Brother, ALWAYS...Keep it turning my machining brother.
I think You are a greate teacher, superb teaching video. Today I believe The DeCarlo family has in You the best of friends. Our prayers for them and You.
Mate, your videos are bang on. I really appreciate you sharing your knowledge with us. Unfortunately I didn't have a decent tradesman to learn from whilst I was doing my time.. But thank God I have youtube and real engineers willing to teach. Bless you brother. Thanks all the way from NZ
Joe, I CUT 18 TPI ON A 10EA, 48 L X 1.25 D X .065 W. THREAD WIDTH .400 X .083 D. I GROUND A 60 DEG. 1/2" CUTTER BY HAND AND USED YOUR TECHNIC TO CUT THREADS. AT 83 YEARS I DON'T GET TOO EXCIDED BUT WHEN I TOOLI WAS LIKE A 10 YEAROLD AT CHRISTMAS. I HAVE A TWO OLD HIGH SCHOOL BUDDIES THAT WERE/ARE TOOL AND DIE MAKERS AND SHARED YOUR TECHNIC WITH THEM. I AM A SELF TOUGHT CHIP MAKER AND RESTORE /MODIFY 1928 TO 1960 FORD STEERING GEARS, DOING THAT SINCE 1972. I WATCH YOUR VIDEOS A LOT AND REALLY APPRECIATE THE WAY YOU EXPLAIN THE PROCESS AND TRY YOUR WAY. I HAVE A VERY WELL EQUIPT SHOP, AND AVERY UNDERSTAND WIFE. THANK YOU AGAIN FOR YOUR EXPERTISE. GREG EDWARDS-- GASTON, OR
As always, a very well done video. Please don't apologize for 'soliciting' help for your friend! People can't pray and support others if they are unaware of their needs. I applaud your friendship and recognizing you've got 12K internet fans / cyber friends here, just because we haven't had the pleasure to meet in person yet.
A prayer for your friend. I hope he beats this cancer and it never comes back. Love watching and learning from you. I have used your center finder gauging system and it is so easy and on point. The reverse threading is pure genius.
a Another great video. I wish you were my machine shop teacher when I was at school. your tutorials and demonstrations are great. Thank you. All the best from Australia. You and your friend will be in my prayers for a long and healthy life and friendship.
Best wishes to your buddy, From across the pond. here in England. great video. Don't worry about the time between your video's When they arrive they are worth waiting for. As an amature its great to see a pro like yourself taking your time to show us how it's done.
God bless him. I'll put him in my prayers. My father had pancreatic cancer 17 years ago, and sadly it was discovered after it had already advanced to stage 4-5 and he sadly lost his battle. I'm sure Joe knows that this is one cancer you never want to be diagnosed with.Not that you ever want to be told you have cancer by any Doctor. But there have been advancements in the years that have past since my dad passed so hopefully Joe's was caught earlier and that will certainly give him a fighting chance.
best of wishes to your buddy. and thanx for putting your common sense approach to machining into easy to follow and understand videos. please keep it up
Awesome job you have helped me by giving me more confidence at threading internally, thanks a lot. I look forward to seeing more of your teaching. God Bless
Much appreciated. My first machining video was august of 2016. I had other unrelated videos, but zero subscribers and less than 250 total views in 5 years.
Just want to say thank you. I have taught myself how to run a mill and a lathe I only have a small hobby lathe and mill using books and videos like yours thank you so much for sharing your knowledge. I just wish I had found out how much I enjoy this when I was younger my career path would have been a lot differnt.
Very clear instruction and excellent videography. I'll be trying to master this way of threading. I know that the body can be an enormous test, sometimes overpowering the mind, but it sounds like your dear friend Joe is not letting it control him. Get well wishes and prayers for recovery from me, here in Greenland.
Thanks for showing this method. I use the “backwards way” whenever I can. I figured this out yers ago when I had to thread up to a shoulder. I found out that I could see the chip coming off of the tool. And everybody knows that a better finish happens with a high surface speed. One thing though, the entry chamfer is better when it is 30 degrees off axis rathe than 60. In my shop now, most machinists I’d thread from the inside. It is a whole lot easier.
Joe. I know its some months ago since this video came out but hoping for the best for Joe and his family. Also yourself. You've got a good style and I never fail to pick up a new trick or tip with watching. Here's one that will make your hair go grey. Internal Metric threading 1.75 to a shoulder. Compound at 29.5 deg. Threading away from the chuck as you like to do and with disengaging the half nuts on every pass, then resetting and engaging the half nuts with the entire gear train right back on track for the next pass. I know you like a challenge.
I actually saw a video on that. Its not as hard as you may think. You do have to turn the machine off for the carriage movements. I personally don't do much metric threading.
Nice work! Attitude makes a huge difference when battling a disease or recovering from an injury. Sending some positive thoughts and healing energy your friends way.
Hi Joe Have been watching your vids for ages now picking up on stuff i learnt and forgot from years ago but principals remain. I have just received my new lathe and the stuff that you are turning out is inspirational to me.i can’t wait to get started again.
Awesome video Joe...I've been a machinist for 30 years and this is a great one. Last job I had was in a hydraulic cylinder repair and rebuild shop..Alot of reworking..Thanks
Joe Pieczynski I posted my name not to receive credit/acknowledgement but hoping that it would spur other YT creators/viewers to donate, lost a great bud to cancer and named a tool after him that I built hoping my build was a tough and strong as my friend....The Mitchell
Chuck. Immediately following this message, I will raise a beer and toast your friend Mitchell. I thank you for helping my buddy out and just have to remind all my guys that anything helps. It doesn't have to be some big grand gesture. This family is awesome and will benefit by anything coming in. Thanks for signing your name to your donation. I am moved by your thoughtfulness, and look forward to shaking your hand at the bash if my plans pan out. Regards, Joe Pie.
Hi, I've had a lathe for years but never cut a thread because of the info available! You have made me want to go out and cut some now! Thanks you are a star!!
Razor sharp reflexes on that thread. I haven't seen a thread done that way before and without an undercut or even at that manual speed incase the tool picks up. Interesting video and always a pleasure. Thanks for sharing. 🇬🇧
This is a great hint. I had some 1" AL tube I needed to thread internally at 24 TPI. Using this method I completed the thread with a good fit in three passes at 460 rpm. As long as you can hit your number the speed is not too important. Particularly helpful is you can control the length of the thread very closely.
Hi Joe, really like your videos and the way you do things God bless your friend and prayers for him. I am getting over throat cancer myself so far cancer free and back to work part-time my hair is just coming back beard doesn't look real good on one side. Oh well. Thanks again, Scott.
Good look Joe. I was always terrified of crashing the lathe when threading and this is a great solution. You still have to have quick hands on the half nuts with the chuck spinning that fast!
Hi Joe. I know this is an old thread, but I wanted to thank you for it. You and I have 'spoken' a number of times - I am the professor at UT who lives in the Austin area. In any event, this video just saved me from the 'pucker factor' many times over. For fun, not commercially, I am making my own 'fancy' muzzle brakes, and they need internal threading (3/4"-24 or 5/8"-24) to a shoulder. Most people just use a bottom-tap, but I have always felt like that was 'cheating' when you had a lathe :) In fact, all of the 'old hands' who do this commercially just recommend a bottom-tap (if you don't have a CNC) since they say 'small diameter internal threading is too difficult for many people on a manual lathe'. However, this method makes it super-simple. I actually don't understand why everyone doesn't do it this way, since there is no downside that I can see. I recognize that for external threads, there is a (potential) downside to the 'upside-down' method that you advocate - namely, that lathes are designed for downward pressure on the tool-holder, not upwards pressure. There is also the 'awkwardness' of mounting your tool upside down. Neither is a deal-killer, but I can at least see the argument against. However, this internal threading technique has none of those issues and is just dead simple. Plus, if you rotate your compound clockwise to the 29 or 29.5 or 30 degree angle, you don't have to plunge cut the threads. This is a great technique and there is simply no reason why someone should do it the other way. Thanks again.
Thanks for the reinforcement. I personally wouldn't even consider any other method. Anytime you can eliminate the pucker factor or scrap potential, I'm in. Stay well and Happy Holidays. Hook em Horns !!
Another Great Video, Joe! Keep up the great work! I learn a lot from you. I also have learned that you are one outstanding human being, too! Wished that there were more just like you in this world, buddy.
Thanks Joe! My old lathe had a thread on chuck so was terrified to try threading with the spindle running in reverse. I have a part I need to make and am going to try this on the new lathe!
Thanks for the video!!!! I am just a hobbyist and I learn a lot from you. Greetings from Paraguay, South america. Best wishes for you and your friend!!
I have been a machinist /toolmaker for 42 years but I'm always ready to learn something new. I will always thread away from the chuck unless there is plenty of room to thread in. Right now, in my garage machine shop, I'm threading metric threads on a Chinese lathe, with an American leadscrew. This means that once engaged I cannot disengage until the thread is finished. So threading out is a must. A little spooky.
Joe, the head looks good. That's the way I keep my head. I'm bald on top so it looks better that way. Plus I like the way it feels. Girls like it too. Keep the videos coming. You've been very inspirational to me, a nubee.
Technically not. when a right hand and left hand helix overlap, they only do so at 1 point on each helix. Though it appeared I dusted the OD, the tool encountered only the displaced material and didn't reduce the OD. If I had returned the carriage extremely slow to the start point, there may have been a measurable change.
@@joepie221 , thanks for your reply Joe... I thought you did that on purpose in that one part of your video and then you forgot. I stand corrected, thanks.
I had to do a 1.5"-12 thread inside a 1.5" deep hole in a 4 x 6 part with the hole offset. This worked great? Pre-Drilled hole to 1" to have something to indicate with in a 4 jaw chuck. Thanks for the video. I am a new believer in threading away from the chuck.
Hi Joe, best wishes and prayers to your friend, cancer has taken so many. My question is, using this technique how would one do a metric thread? will have to experiment with this. Always enjoy you videos, you explain things very clearly and as they say you are never too old to learn.
Using the same method for about 5 decades, I adjust the compound to full thread depth an then set stop or DRO. I then cut thread to full depth. I single point all ID threads this way because I can see the chip and see how the tool is doing. I had to figure out how to do this a long time ago when I had to thread up to a shoulder. It worked so well that I now use it all the time. The hardest thing is finding a left handed boring bar. I usually grind an HSS tool. I also found out that if the entry chamfer is 60degrees instead of 30 degrees it is much easier to start the thread.
Hi Joe, This is an easy grooming to maintain, the zero $$$ type. Hope cancer don't hit me soon cause I shave flat the leftover hair and fuzz in my face about once a month as a preventive measure... Wish your good buddy the best from me... Glad you're back... If it keeps on like that you'll need to quit the day job... LOL Cheers, PIerre
Thanks Joe !..... I was wondering how you went about doing internal threads going out with the carriage ! now I know !!! you taught me something....Again ! thank you ! ( just so you know, I only thread external threads with the tool upside down and in reverse.... it is so much easier and has no worries about it ! thanks again ! ) Bob.....
@@joepie221 and Your suggestion of using a live center on your part should stop any screw on chuck from coming off.... another great tip from you ! THANKS ! Bob......
It has been more than 25 years since I cut an internal thread. I recently reactivated my shop and I had to refer to my class machine shop textbook and machinist manual to determine the bore size for my case which was a 1.25" x 20 nut. I liked your procedure. I did not find a good explanation of how to determine the target hole bore size to start the threading process when I read the information in the handbook or my class textbook. The following is what I think is correct regarding where the numbers you mentioned came from that I think may be helpful to mention. I assume you looked up the minor bore diameter in the Machinist Handbook for the 2.25" x 12 internal thread used as the example in your video. The handbook cites for a class B fit 2.25 x 12 internal thread as a range, 2.160 to 2.178 =+/- 0.008". Thus the average diameter hence hole size to be bored is 2.170" as you mentioned in the video. The depth of the thread or depth of cut is calculated by subtracting 2.170 from 2.250", 0.080" on the diameter, but the thread depth is 1/2 the diameter value, 0.040". The threading process starts by finding the touch point on the compound scale where the threading tool point makes contact on the part. In your case your compound scale read 33, thus you need to turn the compound to 113 (33+ 40 = 113, where each compound scale division = 0.001"). I liked the burr clean up suggestion. I hope I correctly determined where the numbers in the video came from. I never try to calculate in my head how much is needed to be changed in measurements rather I always write down the starting points and set indicators at 0.0 before I make the cut to the calculated difference. In the above example, some users may prefer to have set the compound to 0.0 and then know they need to crank in 40 units on the scale to get the correct depth of the thread. Again, you made a very helpful video. Thanks.
Thomas Grimes if I understood rightly, Joe did not use the compound at all in the thread cutting but made all depth changes with the cross slide. He only wrote the starting number 33 on the compound to remember it for coming back later to take burrs off top of thread.
This weekend I will be attempting my first thread cutting operation on a lathe...a 1-1/16” 20tpi internal right hand thread to a shoulder in mild steel. Only plus for me is my chuck is a bolt on. Wish me luck! 😂
Thanks Joe another great vedio I ran a old South bend lathe with a Screw on Chuck.To not run into The bottom on a blind thread, I Made a stop with a inside battery , A push button and a small lite. The light was set to come on when The threading tool reached the end of the cut. Crude but it worked , you had to pay attention and be Quick !
hey Joe,,,,,! Thanx Bro,,,,,!!!!!! Just made a 5c draw bar out of a 1" SCH 40 black pipe. - Used this technique. No problems at all. Beats the hel lout of threading TO a hard stop.. I'll never do it any other way as long as I live. Thank you fo passing this great Toolmake info on (Hope the young kids ae watching and paying attention) Steve Fom Cleveland.
I would of liked to see the pd wire set used "D" version. saw and liked your other video. And your Good Habits is a plus. I showed your videos to some young upstarts. my kids start at 10-14 years. using Grizzly 8668 lathe. your Videos are greatly appreciated.
That internal bore can be tricky. I've wanted to make some train horns for years but have strayed away from that specific part! It looks like this threaded design might work even better to adjust the pressure on the diaphragms! The mill sounds great by the way, sounded like you had some issues there before!
The mill is so much quieter. Its a joy to operate. The only worry on a train horn is many are PVC now for the home guys. Light pressure in the lathe is very important when threading PVC, or it distorts as soon as you open the chuck. I would like to make those horns too. Always good to hear from you Chubbza5. Thanks for checking in.
SORRY ABOUT YOUR BUDDY HOPE ALL IS GOOD WITH HIM. I am buying a lathe tomorrow 13-40 doall. And i just wanted to say THANKS FOR TEACHING ME YOUR THREADING METHODS. I have not cut any yet but your non crashing style makes all the sense. THERE MIGHT BE 10 WAYS TO SKIN A CAT BUT ONLY MY WAY IS RIGHT.
Best wishes for your friend. My good co-worker has battled cancer TWICE and won. Two different types of unrelated cancer during 6 years. I like the idea of "inward and out" threading, but it does not seem like an viable method when working with metric threads where (in most cases) the half-nut has to stay engaged through the entire threading operation.
My only experience running metric threads was on a 1640 Victor lathe. It had a push button jog button and a large foot brake. The control of an engaged carriage was amazing. Though getting back to the bottom of the hole may be tough, this method should still work. Thanks for your well wishes.

Glad to help. I was lucky enough to attend a very well equipped High school and never skipped a beat. This trade can be a lot of fun.

Awesome video Joe...I've been a machinist for 30 years and this is a great one. Last job I had was in a hydraulic cylinder repair and rebuild shop..Alot of reworking..Thanks
Dude, you do this so well the movements of the machine look cnc. It will be a long long time until i can run at that level.
Thank you very much.
Hey Joe, you are a good man, wishing you and your buddy all the best from the UK.
Much appreciated
Prayers for your bud/family....it is true grit to fight cancer! Thanks for the tip/video.....lots of lessons

Great tip, when I get access to a lathe in which I can do this I am going to give it a try.
Positive thoughts for your friend and his family.
You’re a good friend Joe. Thanks for the great videos!
great video, good information.
it is very nice to have a friend like you, so thoughtfull to help out, my prayers are with your buddy.
Thanks. Joes a good man and doesn't deserve this.
This is a great hint. I had some 1" AL tube I needed to thread internally at 24 TPI. Using this method I completed the thread with a good fit in three passes at 460 rpm. As long as you can hit your number the speed is not too important. Particularly helpful is you can control the length of the thread very closely.
Another tip would be to increase the RPM as the pitch of the thread gets finer. It keeps the threading dial from crawling at a snails pace.
thanks for the tips and our prayers go out to your buddy.
Watched previous then MADE SPINDLE / CHUCK lock for late 1800's Seneca Falls 'Star' lathe.. TEACHER keep up the good work...
Thank you
Hi Joe, really like your videos and the way you do things God bless your friend and prayers for him. I am getting over throat cancer myself so far cancer free and back to work part-time my hair is just coming back beard doesn't look real good on one side. Oh well. Thanks again, Scott.
God Bless you my friend. I hope you got it beat.
Thanks
As always good sensible advice. Thanks Joe. Hope your friend gets better, I've followed the link on your site.
Good look Joe. I was always terrified of crashing the lathe when threading and this is a great solution. You still have to have quick hands on the half nuts with the chuck spinning that fast!
You could slow it down, but I thought it was more dramatic to rev it up. Thanks for watching.
Hi Joe. I know this is an old thread, but I wanted to thank you for it. You and I have 'spoken' a number of times - I am the professor at UT who lives in the Austin area. In any event, this video just saved me from the 'pucker factor' many times over. For fun, not commercially, I am making my own 'fancy' muzzle brakes, and they need internal threading (3/4"-24 or 5/8"-24) to a shoulder. Most people just use a bottom-tap, but I have always felt like that was 'cheating' when you had a lathe :) In fact, all of the 'old hands' who do this commercially just recommend a bottom-tap (if you don't have a CNC) since they say 'small diameter internal threading is too difficult for many people on a manual lathe'. However, this method makes it super-simple. I actually don't understand why everyone doesn't do it this way, since there is no downside that I can see. I recognize that for external threads, there is a (potential) downside to the 'upside-down' method that you advocate - namely, that lathes are designed for downward pressure on the tool-holder, not upwards pressure. There is also the 'awkwardness' of mounting your tool upside down. Neither is a deal-killer, but I can at least see the argument against. However, this internal threading technique has none of those issues and is just dead simple. Plus, if you rotate your compound clockwise to the 29 or 29.5 or 30 degree angle, you don't have to plunge cut the threads. This is a great technique and there is simply no reason why someone should do it the other way. Thanks again.
Thanks for the reinforcement. I personally wouldn't even consider any other method. Anytime you can eliminate the pucker factor or scrap potential, I'm in. Stay well and Happy Holidays. Hook em Horns !!
i've learned more from you than from my machining school teachers in two years =D
Glad to help. Maybe you should show them this channel.
Thanks again Joe for your method of cutting an internal thread. I appreciate your help !!!
Another Great Video, Joe! Keep up the great work! I learn a lot from you. I also have learned that you are one outstanding human being, too! Wished that there were more just like you in this world, buddy.
Thank you for the compliment.
Your're a good man Charlie Brown! Best wishes to Joe. And you look good with the short hair. Very informative for an amateur machinist like me.
Thanks Joe! My old lathe had a thread on chuck so was terrified to try threading with the spindle running in reverse. I have a part I need to make and am going to try this on the new lathe!
Thanks for the video!!!! I am just a hobbyist and I learn a lot from you. Greetings from Paraguay, South america. Best wishes for you and your friend!!
I have been a machinist /toolmaker for 42 years but I'm always ready to learn something new. I will always thread away from the chuck unless there is plenty of room to thread in. Right now, in my garage machine shop, I'm threading metric threads on a Chinese lathe, with an American leadscrew. This means that once engaged I cannot disengage until the thread is finished. So threading out is a must. A little spooky.
I've never enjoyed metric threads.
@@joepie221, I've learned several new "tricks" from you, Joe and I appreciate it.
Great show of support for your bud, also great video looks fast and great way of threading. Prayers for Joe and family God Bless Ya Dave
Thanks, Joe. You teach me so much. Very much appreciated.
Absolute amazing, i will never thread the old way again. Thanks
Glad you enjoyed it
Backward internal threading is the best and I learned it from . Thnx ❤
I'll never do it any other way. thanks for watching.
I want to learn and only do my treading like you,,,your friend will be in my prayers tonight
Thanks for the thought.
Thank you for sharing this method. I see the beauty of it. It certainly takes the stress and variation out of process.
Prayers and best wishes to your buddy.
Awesome video! Prayers for your friend
Thank you. Good friends are hard to come by.
good . have to try it some day.may not be that easy. but i will try it . thank you sal.
Hope your friend has the same outcome as me. I had a Whipple Procedure done for my pancreatic cancer 16 years ago. I'll be praying for him.
Thanks. I had to say goodbye to Joe. He fought well.
Joe, the head looks good. That's the way I keep my head. I'm bald on top so it looks better that way. Plus I like the way it feels. Girls like it too. Keep the videos coming. You've been very inspirational to me, a nubee.
Thank you.
22:30 remember Joe, you ran across the crest with the tool... that flattened those crest... Thanks, you are awesome.
Technically not. when a right hand and left hand helix overlap, they only do so at 1 point on each helix. Though it appeared I dusted the OD, the tool encountered only the displaced material and didn't reduce the OD. If I had returned the carriage extremely slow to the start point, there may have been a measurable change.
@@joepie221 , thanks for your reply Joe... I thought you did that on purpose in that one part of your video and then you forgot.
I stand corrected, thanks.
I had to do a 1.5"-12 thread inside a 1.5" deep hole in a 4 x 6 part with the hole offset. This worked great? Pre-Drilled hole to 1" to have something to indicate with in a 4 jaw chuck. Thanks for the video. I am a new believer in threading away from the chuck.
Hi Joe, best wishes and prayers to your friend, cancer has taken so many. My question is, using this technique how would one do a metric thread? will have to experiment with this. Always enjoy you videos, you explain things very clearly and as they say you are never too old to learn.
Nice tip, like the head cut.
Thanks for the great videos
Joe Pie 1, bed head zero. I like the short hair.
Using the same method for about 5 decades, I adjust the compound to full thread depth an then set stop or DRO. I then cut thread to full depth.
I single point all ID threads this way because I can see the chip and see how the tool is doing.
I had to figure out how to do this a long time ago when I had to thread up to a shoulder. It worked so well that I now use it all the time.
The hardest thing is finding a left handed boring bar. I usually grind an HSS tool.
I also found out that if the entry chamfer is 60degrees instead of 30 degrees it is much easier to start the thread.
I agree on the entry chamfer thought. I use a 45 when I can and it blends well.
Hi Joe,
This is an easy grooming to maintain, the zero $$$ type. Hope cancer don't hit me soon cause I shave flat the leftover hair and fuzz in my face about once a month as a preventive measure...
Wish your good buddy the best from me...
Glad you're back...
If it keeps on like that you'll need to quit the day job... LOL
Cheers, PIerre
Thanks Joe !..... I was wondering how you went about doing internal threads going out with the carriage ! now I know !!!
you taught me something....Again ! thank you ! ( just so you know, I only thread external threads with the tool upside down and in reverse.... it is so much easier and has no worries about it ! thanks again ! ) Bob.....
I will never thread towards a chuck or collet again.
@@joepie221 and Your suggestion of using a live center on your part should stop any screw on chuck from coming off.... another great tip from you ! THANKS ! Bob......
It has been more than 25 years since I cut an internal thread. I recently reactivated my shop and I had to refer to my class machine shop textbook and machinist manual to determine the bore size for my case which was a 1.25" x 20 nut. I liked your procedure. I did not find a good explanation of how to determine the target hole bore size to start the threading process when I read the information in the handbook or my class textbook. The following is what I think is correct regarding where the numbers you mentioned came from that I think may be helpful to mention. I assume you looked up the minor bore diameter in the Machinist Handbook for the 2.25" x 12 internal thread used as the example in your video. The handbook cites for a class B fit 2.25 x 12 internal thread as a range, 2.160 to 2.178 =+/- 0.008". Thus the average diameter hence hole size to be bored is 2.170" as you mentioned in the video. The depth of the thread or depth of cut is calculated by subtracting 2.170 from 2.250", 0.080" on the diameter, but the thread depth is 1/2 the diameter value, 0.040". The threading process starts by finding the touch point on the compound scale where the threading tool point makes contact on the part. In your case your compound scale read 33, thus you need to turn the compound to 113 (33+ 40 = 113, where each compound scale division = 0.001"). I liked the burr clean up suggestion. I hope I correctly determined where the numbers in the video came from. I never try to calculate in my head how much is needed to be changed in measurements rather I always write down the starting points and set indicators at 0.0 before I make the cut to the calculated difference. In the above example, some users may prefer to have set the compound to 0.0 and then know they need to crank in 40 units on the scale to get the correct depth of the thread. Again, you made a very helpful video. Thanks.
Thomas Grimes if I understood rightly, Joe did not use the compound at all in the thread cutting but made all depth changes with the cross slide. He only wrote the starting number 33 on the compound to remember it for coming back later to take burrs off top of thread.
LVLY. we were doing threading this way 30 years back.
nice to see after 30 years.
This weekend I will be attempting my first thread cutting operation on a lathe...a 1-1/16” 20tpi internal right hand thread to a shoulder in mild steel. Only plus for me is my chuck is a bolt on. Wish me luck! 😂
Good luck!
Thanks Joe another great vedio I ran a old South bend lathe with a
Screw on Chuck.To not run into
The bottom on a blind thread, I
Made a stop with a inside battery ,
A push button and a small lite.
The light was set to come on when
The threading tool reached the end of the cut. Crude but it worked , you had to pay attention and be
Quick !
I made a setup like that for deep blind hole undercuts and blends.
hey Joe,,,,,! Thanx Bro,,,,,!!!!!! Just made a 5c draw bar out of a 1" SCH 40 black pipe. - Used this technique. No problems at all. Beats the hel lout of threading TO a hard stop.. I'll never do it any other way as long as I live.
Thank you fo passing this great Toolmake info on (Hope the young kids ae watching and paying attention)
Steve Fom Cleveland.
Excellent. Watch the OD threading video too. Its a game changer.
I wish the very best for your friend Joe.
thanks for making your informative and well produced videos and sharing great information.
Thank you for your thoughts. Joe lost his battle, but will always be in my thoughts.
i'm sorry to hear that. my condolences to you and his family
Thank you. Joe was my good friend and will be sorely missed by all of us.
Thanks Joe for another wonderful video
Glad you enjoyed it
you convinced me to learn the threading with away from the part direction.
you look like Krav Maga combat instructor.
Great information! I am getting ready to do some beefy acme threads and I will do it this way to avoid a crash. Thank you.
Its good to be able to relax when threading. Have fun.
I would of liked to see the pd wire set used "D" version. saw and liked your other video. And your Good Habits is a plus. I showed your videos to some young upstarts. my kids start at 10-14 years. using Grizzly 8668 lathe. your Videos are greatly appreciated.
Thank you. I hope they help to instill some core values they can take forward and apply across the board.
thanks for tips our prayers to your friend
This is such a great tip. Thank you for posting, greatly appreciated.
Try it. Its soooo much better.
This will also work well turning a thread close into the chuck. No need to have the quick draw hand on the lever.
sir, I hope you good buddy keeps well, I send you and him my best wishes, take care sir, Jack from essex England
the new haircut looks great. I know this video is a few years old. I hope your friend Joe is doing well
I unexpectedly really like the super short cut. Unfortunately, my good friend Joe lost his battle and we had to say good by. He is missed.
Great operator tips and knowledge. Including not using a spin on Chuck in reverse.
That probably wouldn't end well.
That internal bore can be tricky. I've wanted to make some train horns for years but have strayed away from that specific part! It looks like this threaded design might work even better to adjust the pressure on the diaphragms!
The mill sounds great by the way, sounded like you had some issues there before!
The mill is so much quieter. Its a joy to operate. The only worry on a train horn is many are PVC now for the home guys. Light pressure in the lathe is very important when threading PVC, or it distorts as soon as you open the chuck. I would like to make those horns too. Always good to hear from you Chubbza5. Thanks for checking in.
Thank you for the excellent video, all the dest for you and your friend.
Thank you
SORRY ABOUT YOUR BUDDY HOPE ALL IS GOOD WITH HIM. I am buying a lathe tomorrow 13-40 doall. And i just wanted to say THANKS FOR TEACHING ME YOUR THREADING METHODS. I have not cut any yet but your non crashing style makes all the sense. THERE MIGHT BE 10 WAYS TO SKIN A CAT BUT ONLY MY WAY IS RIGHT.
Your a great friend and teacher joe,
Thanks. Happy to do it.
Hey, Joe I hope your friend Joe is still with us! I am also a pancreatic survivor of 11 years now.
Congrats on beating that. My buddy wasn't so lucky.
@@joepie221Sorry man. Losing a friend really hurts.😥
Great video, Joe. I'm gonna try that with an internal Acme thread.
How did you get on with the internal Acme thread cutting?
Such fascinating work, the master makes it look EZ
Thanks. I have lots of practice.
Best wishes for your friend. My good co-worker has battled cancer TWICE and won. Two different types of unrelated cancer during 6 years.
I like the idea of "inward and out" threading, but it does not seem like an viable method when working with metric threads where (in most cases) the half-nut has to stay engaged through the entire threading operation.
My only experience running metric threads was on a 1640 Victor lathe. It had a push button jog button and a large foot brake. The control of an engaged carriage was amazing. Though getting back to the bottom of the hole may be tough, this method should still work. Thanks for your well wishes.
