A Better Tool Post Nut || INHERITANCE MACHINING
Вставка
- Опубліковано 30 тра 2024
- Welcome back to the machine shop! This video I’ll be making a much needed metal lathe upgrade and machining an improved tool post nut for my Phase II quick change tool post. As usual I start the design process at the drafting table before moving over to the engine lathe. Seems simple enough of a project, but that doesn’t mean it isn’t ripe for a slew of machining fails. This was bound to happen when trying some new techniques for the first time. Like metric thread cutting, precision compound rest adjustment, taper turning, and some questionable setups on the vertical milling machine.

Thanks for watching everyone! Be sure to tune in Friday, August 5th for another fun project! If you'd like to tackle this project yourself I have some drawings on my Patreon that might be helpful!
With metric threads on an imperial lathe you need to turn it off and not disengage the half nut. retract. run lathe in reverse, then go in for the next pass. even hiitting the same mark on the thread cutting die you wont re enter the thread at the same point
When hatching a section, the internal thread must also be hatched, since it is located in the body of the part.
The part itself could be sharpened with a cone in the opposite direction, then the perpendicularity of the end and the average diameter of the thread would be ideal, and the less important upper end could be cut from the second setting. Or trim the end on a threaded mandrel.
It would also be good to harden the nut to 35-38 HRC, this will increase its durability.
In general, thoughtful and pleasant work, it's great!
What's the name of the precise line/length sketchinging thing you use in drafting part of your design that would make so much stuff more streamlined. Please and thank you someone
@@hjdt1 Ironically enough, it's called a drafting machine
@@R3dryuu It's still possible. You can disengage half-nuts, retract, stop the machine, and then run the machine (and threading dial) backwards until you hit the same mark on the threading dial, before re-engaging to extract the tool. As long as you don't allow the dial to make a full rotation before stopping the machine, the half-nuts will engage in the exact same spot on the lead screw, and the threads will line up fine.
Don't worry about it. We've all made questionable tool choices. Post nut clarity comes for us all.
😂 😂
Ah, a man of culture.
Well done good sir.
Truth you have spoken brother. You're a scholar and a gentleman!
Speaking of post-nut, i need to send something to The Duchess!

I feel like an "Inheritance Machining" stamp for your drawings may be a interesting project
Also will keep other people from taking snips of his videos without permission. There is a reason Diresta has his name on everything, and then Oxtools did something similar.

I once did a drinking game with a friend of mine: A sip of beer each time one appeares on screen and a shot each time he applies one ...
No side projects? Unsubbed. 😀
😂 a rare occurrence for sure...
Side Project count? Zero
Next week we'll find out it was all one big side project.
Actually he's making a nut for the lathe before he can make a part for the mill, which is needed to make a fixture for the belt sander, to make a part for the press, which is removing a part from the surface grinder, which is being used to sharpen his pencil to design the part needed to get the wife off his back.
@@lolzlarkin3059 so they are all side projects
@@michael7324 Yes.
The original project was to set up a shop to play with the cool tools. After that it is shadow boxing to hide the original project.
Warning: Once you have convinced the better half that nearly anything makeable or repairable can be made or fixed with the addition of just one tool per project. The tool come frequently and the projects come even faster. 😁😎
As a CAD designer - I must say that , i enjoy watching a guy do a technical drawing by hand. Im in ave. Did this in my studies, and many times it was pain in the a... But now when i seesomeone draw things they want / need to do by hand it is kinda mesmerizing.
Thanks! I'm a CAD designer as well and it's absolutely a more tortuous process to do by hand. But I spend enough time looking at screens so it's a nice break.
@@InheritanceMachiningI can't blame you because screens are everywhere so it is nice to get away from them
Excellent as always
Nice to see you here colin
Thanks, Colin!
Machining content is great and all, but seeing how you elegantly recover from your mishaps is what got me hooked.
It's amazing you still have your manual drafting skills intact. I took drafting in high school and I forgot it all. The little I do remember made learning CAD super easy.
I feel like I don't remember much at all haha just drawing lines with a ruler. I'd definitely have to go back and review all the cool compass techniques for drawing polygons and bisecting angles and whatnot.
@Dan Carlson Yeah, there was a lot of attention to the title block as if it was more important than the drawing itself.
I still remember a comment that my 10th grade (1963) drafting instructor made. Draftsmen will always have a job. Before anything is manufactured someone has to draw a picture of it.
It's a bit controversial with experienced machinists but for threading (especially blind) it can be less scraptastic to thread from left to right. Joe Pi has a video with all of the details but basically you flip the tool upside down and reverse the motor. It sounds ridiculous but the results can be quite nice.
I believe you can also use an internal threading tool but hold it on the back side of the work and run in reverse
I've seen this (not by Joe Pi) but I think it takes an opposite hand cutter from what I have. Flipping mine would still require the lathe to run forward, even if I'm cutting on the back side of the bore. Then feeding out would make a left-hand thread. I should get the opposite hand tool since i would prefer to pull out of the bore rather than in
@@InheritanceMachining If the spindle and drive shaft are rotating in the same direction then it will cut a right handed thread, I think, regardless of whether the motor is running forward or backward.
@@OhHeyTrevorFlowers yep
Yeah Joe Py is a wizard
If you have an imperial leadscrew and want to cut metric threads, leaving the halfnuts engaged and reversing out is your only option because the leadscrew pitch is not related to the thread pitch. No changes to the threading dial could fix that. Same goes for imperial threads on a metric machine.
Not so. You can disengage the halfnuts, stop the spindle, move the tool clear of the threads, reverse the lathe then reengage as the same number comes round. The caveat is that the threading dial cannot make a full revolution. Its effectively like keeping the half nuts engaged but with the ability to stop the tool motion immediately. There are a number of contributors on youtube who have demonstrated this technique.
@@ThePottingShedWorkshop Yeah ok true, and I've even done that, but I couldn't think of a quick way to describe it. You did a good job! Leaving the halfnuts engaged is easier most of the time but this technique is great if you're threading to a shoulder or something where you have to end the thread in a narrow window.
@@ThePottingShedWorkshop I was going to say the same thing as you have said. I also check the comments before I post my comment so as to not double up. My main reason for replying to you is to keep your comment near the top so others can be informed of this method. Cheers from John, Australia.
Thanks guys, I learned something I’ll try. I almost exclusively make metric threads on my Southbend Nordic which is an imperial lead screw machine. So far I have just kept the half-nut engaged which just feels bad somehow.
this is a most helpful tip. I have a vintage WW2 Monarch Lathe I'll be bringing back under power soon and there are times when I may need to cut a metric thread. Thanks!
Keep showing your mistakes because it makes all of us realize that teacher is the best.
Absolutely true. Thanks!
Brilliant! As an engineer who designs parts and creates drawings for various manufacturing processes , I always dream of owning a small machine shop. I love the methods you devise to stay within intended tolerance and of course the drafting!
Thank you!
Great job, thanks for showing the mistakes. I have a lot of respect for the integrity you demonstrate in your videos. As always, I'm certain your grandfather would be pleased.
Very much appreciated. Thanks for the support!
As always, an absolute pleasure to watch. Thanks.
Much appreciated!
I love these videos. A self fulfilling hobby is always cool to see. I've only handled a Bridgeport mill once, but it was a memorable experience. Met the man through friends from church. He is a motorcycle builder in his spare time now, but he is a self trained engine expert. He used to make parts for F1 and the skill he showed proved it. Wise and patient man. I'll never forget it. Can't wait to build my own shop one day.
That's awesome. One thing is for sure, once you catch the machining bug it never goes away. Good luck on the shop build!
My father taught Mechanical Drawing and Architectural Drafting for 30 years. I got as much enjoyment out of watching your drafting skills as I did your machine work. A lost art to be sure.
I'm glad! thanks for watching!
Well done, love the honest discussion of bumps and how to work around them!
much appreciated!
Seems like multifix is the new craze these days. Good to see someone give the poor Aloris extra love.
Love this channel because I am in the middle of my apprenticeship and still have a lot to learn about machining (especially with the lathe) and while watching your videos I always try to think of the way I would have done the part.
That's great! There's always a different or better way to make a part. Which is fortunately since not every shop has the same tooling
I've said it before, but I'll say it again. I appreciate seeing your mistakes. It reminds everyone that making mistakes is part of making. Everyone does it and everyone just has to try to learn from their mistakes.
Thanks. That's my hope by including them. If someone can learn from watching me mess up then it's worth sharing
Glad I'm not the only one who makes regular use of the f@#ket bucket during projects. A nice addition to your lathe
since I'm in the shop alone 99% of the time, thats probably the most common word spoken aloud in there. already spoiled by the handle. I love it
An obvious fix to even a non-machinist like me, but a beautiful end product that looks original to the machine. Nice work!
You are the Bob Ross of machining.
FYI, if you get a left-handed threading tool you can run the lathe in reverse and feed out of the hole. That makes threading blind holes much less nerve-wracking, and permits getting threads very close to the bottom of a blind hole.
That's how I do it. You can also flip the tool that you used in the video upside down and cut O.D. threads in reverse. Joe Pieczynski has an in depth video on it.
As a retired tool & diemaker I can assure you there are always projects to be had. Love your videos!
Jim 922 from Arkansas, video number three, I enjoyed it very much! Your video quality is top-notch. i’ll be watching more of your work soon. Thanks for giving me the opportunity to follow along. Good Job!
I should be thanking you for supporting ME for watching the videos haha thank you!
I have never felt more seen than when you said "well, thats not what I wanted to do."
What a fine and clean workshop and a pleasure to listen to the explanations.
I found myself screaming at my screen, CHECK THE NUT ORIENTATION. On the other hand you make way less mistakes than I do so no big thing .
Love the channel and your presentation style.
😂 I had many less than nice words with myself after i realized my mistake. Good thing I got kind of lucky. Thanks for the support!
Small tip from someone using metric: Metric threads have standardtised pitch, so if you have the nominal diameter you can find the coresponding pitch in a table. There are some fine thread versions with lower pitch that don't cut as deep into the material, but those should be easy enough to tell apart from standard and aren't that common.
Dunno if the imperial system works similar when it comes to threads.
it fun that every new project needs a learning curve to be climbed.
having a youtuber that put his errors in is extremly usefull because in machining, i feel like you can only learn from your own mistake(or the mistake of others, so suffer for my sake)
You could say you're a nut for a better tool post... or not.
There's something a little bit more satisfying about improving one's tools or workspace.
I'm in the midst of a much needed 25+ yr remodel/re-org of my shop. When I bought the place in '98, I had to put in 6 mos of remodeling before moving in.
I emptied the shop, threw tools & shelving/cabs from previous shop in, & went to work. Over the years, more equipment & tools were added until I had passage ways, cramped work spaces & small auxilary shops.
I finally had enough as I came out of chemo recovery last year & started planning an expansion & re-org.
It's so satisfying to be painting, wiring, creating new, more efficient storage & seeing a more organized total work area take shape.
You're an inspiration for doing things right, even if it takes a few tries.

When cutting metric threads with an imperial lead screw you should not disengage the feed but stop and reverse out of the hole before starting your next cut. Works every time for me!
Elegant design. To make this same idea, I simply welded a piece of rebar to an impact socket from Harbor Freight.
It's attractive to me that you show your mistakes. This is somehow comforting and how we learn.
Getting the thickness of the nut just right is a nice touch. One thing about metric threads on an inch lathe is that you have to leave the halfnuts engaged once you start and only reverse the motor to wind out.
thanks! yeah it dawned on me how obvious that is once I realized my lead screw is 4TPI. I actually got a helpful tip on this as well. You can disengage in your stopping window then turn off the lathe. when you run in reverse pick it back up on the same mark. as long as the dial doesn't go all the way around you'll stay aligned
As someone who only has access to a lathe by being on a engineering competition design team in college, I've never really had any training on how to use/set up a lathe. The only training I've received is This Old Tony and maybe a few others. Now that I've found your channel, it's unfortunately time to graduate and I'll lose my access. But wow, I really wish I could have found your channel a while ago because you not only show the chips flying but you provide the problem statement, proposed solution, design process, machining setup, actual machining, and the finished product in use. Its incredible and I love every aspect of your videos. Especially the machining setup, you always provide some real helpful pieces of advice or simply explain how you set the tool up. Thank you!
I know this is one of those things that lots of people say on lots of creator's comment sections but I really do think it's great the way you leave "mistakes" in the final video. It can be really disheartening to watch people just cruise through jobs without a single hiccup, then you try and do something simpler and have it just be an avalanche of mistakes. Love the content, keep up the great work.
I appreciate you saying that. My hope is that others can maybe learn from them, and feel encouraged like you say. And at the very least I can poke fun at myself a little. Thanks for the support!
You videos are such a pleasure to watch. Keep up the great work!
Thank you so much!
When you put the nut in the mill I was confused that you hadn’t tested to see where the handle would land. I figured you knew something that I didn’t, like perhaps you planned on adding washers or shimming the difference after it was done. Very nice work though.
I am truly envious of your shop. Although I’m sure you’d love to spend some more time with your grandfather, having an inheritance shop could feel like you’re still making memories with him every time you step through the door.
Literally 😂 thanks! I've used that technique a time or to. actually tried it here but had a hard time since the inner face was a smaller diameter and couldn't get a good position.
So glad I just found this channel. So much information packed into every episode, and your style is such a joy to watch.
I binged every video over two days, and I already can't wait to see more. Thanks for sharing!
Very much appreciated! Thanks for watching and the support!
Working my way through the catalogue. This was one of my faves
Realy nice :) always a joy when you release one of your videos, hoping to see more in an near future :)
Love that you keep it real, sometimes you have to make mistakes to learn from it :)
Much appreciated!
I really love your videos! Very inspiring. Good to see another perfectionist at work! Great personality and so glad you include you “elements of training” (mistakes) which are our best teachers!
Thank you so much!
I feel like I’be become a fan of a channel that is going to be insanely popular very shortly. I wouldn’t be surprised to see you have 500k subs by the same time next year.
Wouldn't that be something! I'll just keep plugging away! Thanks!
I really like the way you always tell a story. So relaxing to watch.
I'm glad! thank you
your video brought back some memories.... haven't used a drawing board and paper in a long time.
Took drafting in college in the mid 80's. My class was the last to use boards, paper, pencils. CAD (2D) was taught there after.
interesting... my high school vocational classes included 3 years of drafting then a 4th year of 2D CAD. if it weren't for that I may not have the same interest
Very nicely done! Love the results!
Thanks!
Threading dials are (almost) worthless when cutting metric threads on a imperial lead screw or vice versa. The half-nuts must engage in the same exact position in the lead screw. The easiest method I've found for threading blind metric wholes, is to mark the dial as you did. When approaching the end of the cut, disengage the half-nuts and outfeed the cross-slide as usual, and then stop the machine. You can then run the machine in reverse, running the threading dial backwards until you reach your mark, then reengage half-nuts to extract the tool from the bore.
Your videos are really good. And your voice, calm narration and dry humor make your videos quite the relaxing watch. I think you're my new favorite machinist channel. Thanks for all your effort!
I really appreciate that. Thanks so much for the support!
I felt the high and lows in this project too 😂 so satisfying how it came together
Well done. Thanks for showing the mistakes also. So many times tubers cut out the mistakes and it helps so much more to see them so we all get to learn along with you. So much appreciated and makes watching that much more fun. Great job!
Thanks a lot! I'm happy to share the mistakes because just about anyone can relate and/or learn from them. Plus sometimes they are funny
Some good explaining work. Appreciate the post nut clarity.
A trick I use when cutting internal threads is to cut a recess at finished size. In this case 22mm 1/4 deep into the part to be sacrificially machined away when threading operation is finished. As soon as the cutter leaves a trace mark on the recessed inner diameter you know your at the correct thread depth.. Its very advantageous when working with large sizes that no test thread can be had or used. Keep up the great content.
Very nice job. Hopefully you get great use out of it my friend for many years to come. Can't wait to see more videos soon. Keep up the great craftsmanship and hard work my friend. Keep Making. God bless.
Thanks!
Another great project, this is becoming one of my favorite channels.
😎 thanks a bunch!
Glad I watched this. Stoped for lunch and my next op is cutting some metric treads on a part. I forgot about not disengaging the half nut and definitely would of scraped that part. Thanks for the reminder.
Nice! glad I could be a reminder!
As always a great and informative video. Well done sir.
thanks!
We learned in school to never disengage the half nut when cutting threads. Metric or imperial, ever! And yes that means that you get to do a sort of dance with the machine to prevent crashing the tool unless there is a brake or a clutch (schaublin 102) on the lathe. And we had lathes of the same brand and type that had either metric or an imperial feed screw, that was sometimes a bit confusing.
Your channel is growing on me and I am just as excited when you upload a new video, as when I see This Old Tony, Blondie Hacks, etc. Really wish you the best!
That's awesome! Thank you so much!
The UA-cam algorithm finally recommended a great channel. I enjoyed this video 👍and subscribed.
Welcome!
As a newb, I appreciate you showing mistakes. It’s so helpful.
I'm glad! Thanks!
Nice job. I appreciate you sharing your "learning experiences". That handle looks perfect.
much appreciated, Bill! I'm definitely not an expert so I'm doing my best not to give that impression. But hopefully others learn from my mistakes
@@InheritanceMachining That's how we all learn things. Your grandfather would be proud of your efforts and successes. I really enjoy your down to earth presentations. Thanks.
Thanks again, Bill!
As an amateur machinist I find your work informative and entertaining. Looking forward to the next show 👍
I appreciate that, thank you!
Excellent work 👍👍👍 . Thank you for sharing. Take care of yourself 🇨🇦
thanks!
Grate video again. As I see you getting new skills. And methods. I can see you well on your way. I bet your grandfather would be proud. Keep up the great work
Thanks so much!
"Gotta Represent, Na'mean" lol. Perfect,
Perfect project, going to try to make one for the work lathe
Thanks for the great idea!
It's always a good day when we learn something. The nut assembly came out beautifully.
Agreed! thanks so much!
Yet another outstanding video! Thanks for sharing.
Thanks as always!
looks good!
Some day I'll have room for a lathe; and a milling machine. Great work, great result! It's nice to use the machine to make parts for the machne.
Thanks! That's one of the best parts of having a machine shop 😁 I hope you sort yours out as well!
Just subscribed, anybody that admits to being as human as the rest of us is exactly where information and entertainment meet, well done!
I really appreciate you saying that! Welcome!
Its always pleasing when the plan and the minor mishaps work together to make a very pleasant wiggly turny top knut grippy thingy 😁
😂 So that's what it's called?
Perfect timing!!! Just the other day, I too was looing at the top nut on my tool holder thinking it could use a handle. As a fabricator, not a machinist, my first thought was to make a handle to tig weld to the existing nut. However your end result it MUCH more desirable. Guess I better figure out my thread pitches and get my taps ordered. Thank you. You are an inspiration.
I mean nothing wrong with the welding method either, but a machined nut will be much prettier. good luck!
really enjoyed watching this project.
thanks!
"A thing of beauty is a joy forever" - Johan Keats
Just so you Brandon to be honest about your mistakes and yet still build something so beautiful and functional. Thank you as always, loved your tool post nut story 🙂
Well said. Thanks as always!
Changing a part that still works, to find a reason to make a tool we didn't have. I guess we're taking the long way around! 🤪 Great work! I'm glad you're taking us on this little adventure with you.
Guilty 😂 thanks!
You will need to make a nice tool-height gauge for the lathe at some point as a side project. Especially on small diameters eyeballing it with the tailstock won't be good enough. Even a few tenths (yes, tenths of a mm) of height difference can mess up your infeed reading in regard to your actual depth of cut.
I have a height gauge on to-do my list for exactly that reason.
You can make a very simple but quick and efficient one by just turning say a 2" steel bar down to say 1 1/2" for say 5" on a bar that's about 6" long. The 5" length needs to be an accurate length that is the same as height from top face of cross slide to center height. You just sit the 'mushroom' shaped bar on the cross slide and adjust the tool height so the tool just slides under the 2" head. Worked very nice on a smaller lathe than yours. Hard to describe in text!
Don't forget to balance the load on your vice jaws...
Perfect opportunity for a machinist jack side project right there!
Well now the jacks just moved up in priority!
Good catch
You're an inspiring creator. Thank you for sharing.
You are very kind. Thank you!
Nice job as always. We shared this video on our homemade tools forum this week 😎
Much appreciated, Jon!
Thanks for those videos my man. Very entertaining and captivating. And I can so relate to making similar mistakes :D
Much appreciated!
This was enlightening since I learned drafting with a sliding parallel, and have never used a drafting machine. They always seemed mysterious. Now I see their advantage. Is there play/deflection? Thank you for all you do for all of us!
There is a bit of deflection in the mechanism just because of how long the scales are so I have to be delicate with it. Thanks for the support!
Keep on turning!!
A suggestion sir, when you tighten the nut, the tool holder moves unless you hold it. Add a thrust washer under the nut. This does two things, the tool holder won't move when you tighten the nut plus it applies a lot more force,,,no wrench needed. Nice job
Great project! I gotta say I love seeing the manual drafting, that's a great touch IMO....
Much appreciated! I've had a lot of people comment on that. I had no idea people would find that so entertaining. I just do it because my day job is all computers modeling and I'm tired of it haha
Your machining skills and designing skills are very impressive, but I got to say your video editing skills are equally impressive. Your intro and the way the videos are put together is amazing.
Thank you! But I have to give the editing credit to my wife. She's a huge part of all of this
I am building my own hobby shop piece by pice, i love this channel it is so intriguing and has some of the best videography of any machining channel i have seen.
thanks so much!
Nice build. I pinned a wrench onto my QCTP nut for a few weeks before deciding make a new nut and handle, just to make sure it's a change I wanted. I used a bent and cut wrench to simulate what a handle would be like. I found I didn't like it and decided to just hang a wrench close by.
Good to go. That reminds me how i cut inch threats on metric lathe. Same story. When i made a tool holder nut on my lathe i adjust the position of handle just like you.
It would probably help to really dig into and test the engagement points and make a separate tag for the opposite threads. If i get into any more metric stuff it will be a necessity
I hope the outcome made the mistakes hurt less, because I think you nailed the look of this thing! It definitely looks like it could be original. Keep up the great work!
I'm pretty good at rolling with the punches... even when I curse like a sailor 😂 thanks, Jay!
One day when parting off loads of parts I had the idea to stick a piece of round stock in a drill chuck mounted in the tailstock and bring it up into the bore. Just part off and let them fall after that.
I am still enjoying and learning Thanks
I'm a little late so this may not apply (watching you're series in order)
When clamping something at the edge of you're vise, it's good practice to balance the other edge to prevent the moving jaw from canting. While it's only a minute angle, if you're taking heavy cuts the part has a tendency of lifting or moving from not having enough clamping surface.
If my part is 3 inches long and overhanging the jaws even a small amount. I make sure to slide something of the same dimensions on the other side. It's fun when working with parallels and a table mounted stop lmao
Beautiful. It#s just always nice to get a new Video. The toolpost looks amazing now. Don't tell them about the mistakes, if it works out in the end
Thanks! The mistakes are all part of the journey so I'm happy to share them
It does look original with the lathe. Good job. Great job filming and editing.
thanks!
I hate my brain for making me read the title the way I did.
KEEP UP THE GOOD WORK
