A Better Tool Post Nut || INHERITANCE MACHINING

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.

[@R3dryuu]

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

[@M18283898]

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!

[@hjdt1]

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

[@InheritanceMachining]

@@hjdt1 Ironically enough, it's called a drafting machine

[@Jcreek201]

@@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.

[@bobweiram6321]

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.

[@InheritanceMachining]

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.

[@terrybrower3437]

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.

[@antstephenson9497]

As always, an absolute pleasure to watch. Thanks.

[@InheritanceMachining]

[@OhHeyTrevorFlowers]

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.

[@ryanpeterson5239]

I believe you can also use an internal threading tool but hold it on the back side of the work and run in reverse

[@InheritanceMachining]

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

[@OhHeyTrevorFlowers]

@@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.

[@neiljensen9585]

@@OhHeyTrevorFlowers yep

[@StormbringerMM]

Yeah Joe Py is a wizard

[@cooperised]

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.

[@ThePottingShedWorkshop]

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.

[@cooperised]

@@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.

[@joandar1]

@@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.

[@cogentdynamics]

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.

[@hotpuppy72]

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!

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

[@filmaynard]

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.

[@markoglesby1552]

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.

[@Skirakzalus]

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.

[@jaxblonk5127]

Some good explaining work. Appreciate the post nut clarity.

[@samscruff5454]

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.

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!

[@backyardcnc]

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!

[@georgedennison3338]

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. GeoD

[@Jcreek201]

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.

[@jimsvideos7201]

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.

[@InheritanceMachining]

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

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.

[@InheritanceMachining]

I have a height gauge on to-do my list for exactly that reason.

[@patkirk960]

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!

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

Hi, just something I used to do when I was machining parts, at 12:35 you was spending time trying to make sure parts were perpendicular in the lathe jaws, what I used to do what put a parallel behind the part covering the bore in the chuck and bumping my part against it, holding it flat as I close the jaws around it. Of course its not going to be as accurate as with using a DTI but itll get you closer

Something like this is on my list! If I ever get into really small parts it will be a neccessity for sure

Great looking nut....great video, keep'um coming..

[@InheritanceMachining]

thanks, man!

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!

[@InheritanceMachining]

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!

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.

It does look original with the lathe. Good job. Great job filming and editing.

[@InheritanceMachining]

thanks!

a thing of beauty.

Boy did that bring back some memories. I actually started on T-Square and triangle back in Jr High school in 1963 when draftsmen were highly skilled people. I really miss my K&E full track machine (Never had the heart to sell or scrap it but it lives in the attic now) We all had very unique lettering and even arrow heads and other style. You could tell who did a drawing without ever looking at the title blocks. ,,,,, But alas, today I use AutoCad. Hey, at least I still use Dr. French's "Glass Box" to visualize what I am designing. I'm looking up at his book up on the shelf over the computer. I haven't ;looked inside it dor decades, though. Looks like I'm one of the last of the Mohicans for sure. All I see anymore are kids making pretty pictures with Solid Works. Pretty good to generate G-code, but it leaves a lot to be desired when a tool maker needs a working drawing. ,,,,, But then tool and die makers are a dying breed too. Good idea for the nut, but mostly, like Mr. Hope said. Thanks for the memories.

Thanks for sharing! I relate to your sentiment about kids making pretty drawings in CAD. I came from the drafting board as well and it seems to me that those that didn't don't understand the importance of drawing cleanliness and the importance of the dimensions they show as it relates to the machining. Thanks for the support!

Watching this and planning to go do the same thing to my PM 1440 Taiwanese lathe. I think the toolpost screw is a normal, unified, not-metric thread, but...if it is metric, I think I'll make one that is unified. Pretty sure I'd have to put in a new gear set to do metric. And definitely never thread INTO the chuck. I'm tooled to always cut while moving the saddle away from the chuck. Thanks for the inspiration.
