I've been steadying this channel since that first threading video. DOH...not steadying...FOLLOWING!
This deserves a pinned! Hilarious!
Those who do not learn from Joe Pie are condemned to repeat his mistakes.
The inverted, left to right threading technique is probably my most frequently used handy tip I've every gotten. Many pairs of shorts saved by not having to hit that half nut before crashing.😆. Thank you for all of the great info.
Happy to share. Pass it on.
I'm a Toolmaker by trade. Love this guy. I've watched so many Wanna be machinist TH-cam vid's just to get a laugh. Just listen to this man he is taking the time to give you true machinist knowledge. It takes years and years to become this knowledgeable in this trade. I've been in tool & Die for 27 years. My earlier years were years spent doing 10 hr day's manual machining so I'm qualified to say this man knows his shit !
Many thanks for the endorsement my friend. Much appreciated.
Your first video was fantastic. It showed your understanding AND you teaching giftedness. It's great to see that you've consistently "upped your game" over these years. No small feat.
Praise God for his gifts to you and thank you for sharing so generously!
Joe, you are the kind of shop teacher our schools are missing in this day and age. your tutorials are a gem in themselves. Fantastic video :)
Thanks.
@ericsteel7643 Aren’t schools missing shop class completely?
Joe !
Firstly, I need a squeaky pen to be like you 😁
Secondly, the information you give is priceless!
The insight into machining is priceless to me. When I first commented a few years ago when I first had a lathe you replied and you've never stopped helping or commenting. That's what makes you special.
Individuals on here get big and lose contact with their core subscribers, people at the base level, you haven't.
Get well soon mate, all the best from Wales UK
I get a lot of comments but try my best to keep in touch. Thanks for your support.
The sign of a good teacher: Something that was not obvious, suddenly is. Thank you Joe! 👍
Joe,
You got a great reason to just sit back and take things easy but here you are, thanks for that.
When I first had to teach groundschool I was assigned aviation regulations to teach. It would absolutely have been my last choice. In the first few classes we had several students going through the course for the second or third time and I was very encouraged by complements of my teaching especially considering that I was replacing one of the best in our industry. One student finally said "Jack taught us WHAT the regulations are but you teach us WHY the regulations are ".
I've always found it easier to remember things if I know the WHY. Joe Pi does the WHY. Hey, maybe there's another t-shirt in there for Presso.
Cheers and thanks Joe.
Nice presentation. I had a great old school shop teacher that took the time to do just what you are doing here, many years ago. These days when threading goes wrong not many folks have the ability to troubleshoot the finer details of how "movements cause reactionary forces" in machining.
They are always present and should be understood. Makes troubleshooting mush easier.
I was going to say ‘most’ but I won’t because I believe ‘all’ machine shop practices come down to common sense. I don’t think I’ve ever seen anyone of your presentations that hasn’t shown that factor Joe. Nice work, keep ‘‘em coming
@Joe Pie I like how you gave a good, clear, explanation on how center lines work. When I sold hardware, nuts, bolts, for Home Depot it was often difficult to explain to people the difference in shape of threads and how a nut screws on. Like squared off automotive threads will accept a normal nut but the threads won't mesh fully or correctly and the slop will cause part failure.
Hey Joe, just wanna say so glad you decided to make these videos and I'm glad I found you. That threading video was the first video I saw - I wasn't able to thread like that because of my lathe - but I sure improved my threading and much more from watching your videos ( and other people's too). I typically enjoy the practical projects that you suggest we make. Thanks for all that you post.
It's insane that this technology has been around since 250 BC when Archimedes invented his now-famous screw. Keep up the good work I love watching you build stuff. I was an auto technician for most of my adult life but for a year-and-a-half starting in 1971 I worked at Bennett Respiration as a machine operator. I ran a french-made screw machine for a. It sounded something like Cry Dan. I ran a twin spindle collet turret lathe finishing.
.0002" tolerance shaft on the Sigh Valve. I measured it on both a Optical Comparator and a pair of ruby jewels with metered air.
You always amaze me with your "deep" incites into the physical relationships involved in machining. Knowing how to do something is great, but understanding what is going on is your gift to us - THANKS!
I've watched ALL of your videos Joe. Some twice, others three or four times. Maybe that's an indication of my learning abilities but the way in which you explain things makes it 'obvious' why a method will work or doesn't work. That's what I like.
I can't count the number of times Ive watched a lesson and said to myself 'Well, that's obvious'. It IS. But only once it's been demonstrated.
I'm just delving into the world of CNC machining now and I'm extremely fortunate to have a friend who, like you, makes things obvious.
Thank you for taking time to produce these informative videos. I always take something away even if it's confirmation that what I am doing is OK.
My pleasure. Thanks for the support.
So true. Only obvious after Joe has pointed it out!
Joe, I recently struggled with this same issue. watched this video and rechecked my material and yup, you were correct, will remake the part tomorrow with a better piece. thanks Joe.
Good to hear from you Joe.
And on one of your favourite subjects too!
Keep well yourself.
Great teaching, Joe!
I’m always amazed at what I learn from your videos. Well done, sir!!
Never thought about it this way. Thanks for the different approach.
You absolutely have to have some form of follow rest to turn those small diameter threads. I actually built that same style follow rest you used in your videos awhile back. Thanks for the tip.
25 years as Journeyman Tool and Die Maker, and I still watch your videos to learn new techniques. You're simply the best teacher ever! Thank you!!
Thank you. Glad you find them valuable.
Joe another lesson full of information especially to home hobby Machinests, have been watching your channel for along time. I to was taught to thread away from the head stock as an apprentice fifty years ago, it is just so easy and a safe work practice my appretices said at trade school the teachers said it was wrong way until my boy showed them how well it works. I'm retired now but enjoy your videos very much God bless from down under.
Thanks, Joe. Continue to heal.
These videos are better than a book for me because I learn better when I can see and hear the information explained. Thank you Joe for these great videos and all of the time you sacrifice from your work and family to make them. I hope you are able to return to the shop soon. Best wishes to you and your loved ones.
Many thanks.
Thank you for the video. I have recently cut the thread using the method of flipped tool, and travel away from the chuck, that i learned from your previous videos. It worked awesome. Keep up with the sharing, learned a lot from you by now...
You really have a knack for teaching, well explained. Even if You sort of know this it is easy to forget and screw up...
I really liked the video on the phenolic follow rest support with the in situ machined hole. Used that idea several times. Made an adaptor for my usual follow rest that takes a small piece of phenolic on the brass tip, worked really well. Advantage is that the support can be tweaked a little with the adjustment screw on the follow rest. Phenolic is a underrated material as a bearing and gear material. Main gear in my Arboga drillpress is a made of phenolic cloth composite. The material absorbs just the right amount of oil to make a good bearing surface and also reduces vibration.
Thanks for the video Joe! Reminding us that sometimes the solution may have been obvious from the get go and gets overlooked or taken for granted.
Great information, I actually understood what you were talking about. Thank you.
Thanks for the lesson, great information! 👍
For all who had a problem with the „tire“, think of an edgefinder on the mill
and what it does by contacting the surface. That’s what happens when the tool touches…
Hey Joe thank you sir. Good to see you again.
Get well soon!
thankyou for your teaching us
I have also learned that you can't count on round stock to be round. Many times you get the old egg shaped round stock especially in the smaller diameters. Rolling it on a surface plate or even the bandsaw table is a great tip.
Assume nothing and you'll never be disappointed.
Another great video Joe. Thanks again for taking the time to impart your knowledge to us.
Great information, as always. Hope you feel better soon!
Thanks, Joe, the knowledge is much appreciated!
Brilliantly succinct explanation of the real world in the workshop ! The initial statements about co-axial centre lines of material, thread helix, and machine, are something that seems to be missed elsewhere . . . .
Take care in nursing that ankle !
Kind regards,
Steve A.
Thanks Joe, that was very interesting. I have been dabbling with threadcutting and am always willing to take advantage of your expert knowledge. Cheers! Mart in England.
well that explained a couple of my failed threaded parts. thanks for sharing this.
Great commentary on the note of deflection and possibly irregular material. I never considered that to cause the problems I've encountered on long threaded parts.
Nice tip Joe, making a fixture for the stock profile on the Follow Rest !!! Thank you..
If its a nominal size, put an end mill in the collet and just feed the carriage to the cutter for a nearly perfect nest.
Thank you Joe. Hope you will be able to walk out to the shop soon. Hope your recovery is going well.
Coming along nicely John, thanks.
Great video! I continue to be enriched by your clarity of mind and effective teaching style. Get well soon.
Thank you! Will do!
Had to thread a little 5/16-40 part for a Jerry Howell engine, die wasn’t going to come quick enough. Flipped the tool upside down like I’ve seen you do on your videos so I wouldn’t crash, and spent the rest of the day giggling because it came out better than sliced bread and got tighter than I would have managed with a die. Great content thanks!
Outstanding.
Been missing you man… I was so happy we got to unloosen some things today!!
Not 100% yet, but I'm trying.
Great points Joe - and for sure, often overlooked. Thanks :)
Thank you for your help .
It is so educational n enjoyable
Well said, Joe.
You are a natural at teaching.
"Follow Rest" 😉
Greetings Uncle Joe✌🏻, that sharpie chatter😬😂..... just kidding. I learned these lessons well when I had to make a lead screw for a TOS boring mill, had to make the nut too. Lead screw was EN8 n nut was aluminium bronze. The total lead screw length was 1.8m but only 1.4m of thread on it, was 7mm pitch trapezoidal on a 45mm dia. if my memory doesn't fail me. Was hell n fun at the same time😂🤣.
Thanks Joe, always appreciated.
Thanks Joe,you have a nack for giving a lot of us that aha moment and you ride miss it this time🤗😎🤗😎
Thanks Joe! Stay safe!
Thanks Joe! You have a great way of explaining things. Thanks for the great content!
My pleasure!
Joe - Really enjoy your videos. I'm an old retired mechanical engineer who likes to work wood, bash metal and mess with old cars in retirement. In the process I'm trying to improve my skills and knowledge. Along the way I'm trying to teach my two grandchildren (11 and 13) how to work with their hands. This is another good video that can help explain things to them - in this case the components of a force vector. Keep up the good work, it is really appreciated.
Thanks 👍
Joe you have taught me so much. Thank you.
Excellent vidéo. I learned something very useful. Many thanks
Thanks Joe as always another great video I always learn a lot from you
Thanks Chris NZ
I remember your video on reverse threading first came out. Has it really been that long? Thanks for all your informative videos. Please keep them coming.
Excellent work Joe.
Great video. It's kind of common sense but I get some weren't blessed with alot of it. Thanks
One thing I do when cutting/chasing long threads using the follower rest. I leave the live center in your tail stock loose on the end of the part so any runout in the bar is kept concentric at the follower rest. This seems to let you cut a thread with less chatter and keeps a consistent depth of cut, too. When I say runout, less than .002/.003". I try to avoid bar stock with more runout than that. Usually use T,P, & G when i can get it. If I have to turn it down, I rough it to near size, let it cool down. Then set up carefully and start to finish turning to near size, check my concentricity, adjust if necessary, and finish turning. Thanks for sharing, Joe, Ken
that make perfect sense....ive never thought about it that way before thanks for enlightening me ....👍
Glad to help
Thanks for the video Joe.
Thanks, Joe. Short but sweet.
always great to watch your videos Joe, well done and thank you from Florida, Paul
Glad you like them Paul! Thanks.
Good information as always, I'm sure glad that you decided to make that threading video six years ago.
It took on a life of its own after that one.
Andy Zulim - so are 1000’s of others of us!! 👍🤟🏻
Great discussion…tks
Thank you as always!
Many thanks, hope you get well soon.
Thanks Joe. Good tutorial. Succinct and logical presentation.
Thanks Mark.
Excellent. Explicit. Thanks
Lot's of good info Joe, you really add a eyes open perspective to your content.
Cheers
There's a lot going on. Its good to have a broad prospective.
@@joepie221 Agreed
Thanks Joe I have learned a ton off this channel
Threading is always an interesting topic. Thanks Joe.
Amazingly educational. Thank you
Thanks for checking Eric. I hope all is well.
Joe I love the videos you put out and it's really helped me while learning the trade. Could you do a video on threading with the crossfeed dial? The reason I ask is because in your threading video from several years ago, you show how you run threads in reverse by putting the cutter upside down and you keep feeding in with the crossfeed dial instead of the compound. Could you explain how and why you do that? I think with doing it on the crossfeed you're cutting on both sides of the cutter even more, so would that be good on larger stock?
Great presentation that is much needed to advance the quality of the art and perfection of machining! I very much want to use the chuck to tail-stock method of single point threading but would like some advice on how to do this safely with a lathe chuck that is threaded to the spindle so the chuck will not unscrew itself from the spindle during this process. Thanks for the expert fabulous lessons you provide.
Glad it was helpful!
Good stuff sir. Maybe for us new to the hobby could get you demonstrating how to properly setup and use a follow rest? I’ve watch your steady rest video and it was awesome! I haven’t really seen any proper follow rest videos though 💁🏼♂️ just a thought 🤗
As a side note, I throughly enjoy the way you make videos.
Joe thank you for the video. About five years ago I bought a South Bend Lathe 10 in heavy cut. It came with the taper attachment, do you have any videos on how to use a taper attachment Thanks again. I like your T-shirt
Unfortunately, I don't have a taper attachment for my lathe, and RUGER was my bulldogs name. I like the shirt too. ( and all the rugers I own :)
*ALWAYS* look forward to your videos! ? It took me 43 minutes to catch this one ;-)
BTW, it often amuses me when I see people fighting with 'standard' threading into inside bores, or with tight spacing to the chuck... i wonder why more people have not 'caught on' ??
Inverted reverse threading is much lower stress. They really should try it.
Thanks for the lesson even while on the mend!
Presented standing on one foot. :)
Thanks Joe. Always educational. Please post a link to your blog so that we can know why you're not going out into your shop?
Click on his name and it will take you to his TH-cam channel. At the top scroll across to where it says community and click that.
Thanks for sharing 👍
Great vid thanks Joe, the bent stock wasn't something I had considered. 👍 And with that 'unloosen' was like you were never even Mia! 😂👍
Great info as always. Hope you have a speedy recovery.
I Would love to see a video on the use of the follow rest in cases where you want to reduce the diameter of a long thin piece. (something like in a hobby/benchtop lathe, 1 Ft /30cm long workpiece 1/4" / 6mm od) I would love to know how to set it up and how to adjust it after each pass. Do you cut in front of or behind the supported area? left to right/right to left? Do you support on the cut (new) diameter or the old diameter. All kinds of question come to mind if I think about multiple passes on the OD of a part.
I would say to keep the follow rest on the raw material if possible and adjust between cuts.
Thanks Joe.
Brilliant... As always!!
Joe's explanation of the thread error caused by the difference between the center of the stock and the lathe's spindle is another reason to follow your reference book's O.D. dimension call out for the thread you are cutting. This given diameter is smaller than the nominal size of the thread. Unless the stock is badly bent or out of round, turning the called out diameter will usually avoid the problem Joe describes.
The follow rest is your friend to prevent work deflection for long and/or small diameter stock to be threaded. There are several ways to skin this cat. A steady rest with a Vee brass support can be made that clamps to the tail stock quill. It may support the work well enough to avoid the follower rest. On some lathes you may be able to do this from the head stock (now you know what those line-bored holes in the head stock above the spindle are for on very old lathes. It's to hold the bar for the overhead steady rest that uses a Vee or shaped support like Joe illustrated). This style of rest has the advantage of being able to move the tool from one side of the steady rest to the other without having to deal with unbolting and moving a steady rest mounted on the bed of the lathe to the other side of the carriage cross slide.
Following Joe's advice here about faulty threads is really important for Class 3 threads that have long engagements. You turn the threads and all measures well The parts will start to go together just fine and then the fit-up gets worse and worse till they bind up completely.
Cheers from NC/USA
Thanks Joe!
I saw you laughing when you said 'un-loosen', that was so funny, cheers, Paul
Now that was seriously interesting Joe! TFS, GB :)
Ok, it's been 6 years of awesome videos and some of the most useful machining info on TH-cam, or probably anywhere for that matter! Congratulations Joe. But it's WAY PAST time to get some sound treatment for the walls, ceiling, etc. of the office/white board area. The sound quality of the the footage shot in this area is TERRIBLE !!! Sound quality is just as, or more important as, the video quality. Thanks, Joe
Got points as expected. Had not thought about that before.
Thanks for the info. I have a project I'm working on where I have to cut a 16 spline 1.75 inch shaft which are not 90 degree. It's a one time deal. There is not much on here to guide the manual guy on how it can be done. I think allot of guys, myself included on here really appreciate your take on any machine process. Spline lesson please?
Rudy.
Good explanation Joe. I've been doing upside down and backwards threading ever since I saw your video. Except for left hand threads :-)
Left hand threads can be done the same way. Keep the tool upright and thread out. Machine in forward.
You can thread left to right for all threads, right hand, left hand for both external and internal threading. No stress.
Thanks joe
hey joe,- what is your thoughts on flat bottom acme or square thread using a narrower tool with the compound set to 90 and advancing the compound to cut only one side once bottom is met. thus reducing tool pressure and getting a better finish.
I'm all for it.
Your channel is my go to for a "how to actually machine something" channel. Well explained and a logical progression across the board. So thanks.
- Question: Is there a preferred online forum for machining information?
I'm most of the way through retrofitting a mill with a modern (and working!) CNC system and if there is a forum that stands out I have some questions that need answering before my mill is ready to fire up.
There are forums for just about all machining topics. Google it and pick one. You may have to join before you can participate.
After a number of threading failures in school I finally figured it out. First off, RELAX, this is done all over the big blue ball in space every day. Once the count has been confirmed don't mess with the different options on the threading dial. Pick a major line/number and stick with it. Keep it simple and enjoy the experience. LOL, All is well ? your pen is in pain bud, LOL. I have never had a situation like at 6:30. I would think the tailstock has lost contact. Ruger is my choice over many years I have a 338 custom Lapua and 5 other #1's in the safe. Sniper trained in the Canadian Navy they are my choice for rugged strength and reliable simplicity. There ya go. Another thing we share in common. This will help folks understand the physics involved with turning threads. Esp those tiny ones you do so well. I learned a thing or 5 watching you make those impossibly small threads in the mini machine shop builds. Take care Joe. It is always great to see what you are up to eh.
How to make a quill for the support dock with internal MT2 and groove for Mt 2 drill? KV from Finland asking.
I wish... I wish I had found your lessons 30 years ago. I would have figured out a way to convince you that me working for free and learning would have been a good deal for you. Being 50 now I doubt I can find a way to start another career. I'd rather figure out a way to live my last few on a sailboat. You are a heck of a teach. I really love the white board and the math. I just did not know this career existed when I chose to turn wrenches for a living. Yeah, the parts showed up all machined but I just didn't put two and two together
