Making the KING of All Knurling Tools (Finale) || INHERITANCE MACHINING

[@InheritanceMachining]

Thanks for watching everyone! Stay tuned for the next project on Friday, February 3rd. And no... it's not a larger Box of Shame! At least I don't think it is...

[@clydebalcom3679]

I like to think of the box as The Box Of Learning.

[@alexkarsten15]

We'd all like to think it's not a larger box of shame!.. or learning as I now like from clydebalcom3679. Keen as a bean for it regardless of what it is, thanks!

[@joselrodriguez5999]

The box looks deeper :) but still no match to my bin of shame

[@doingstufforatleasttrying4843]

I consider it a box of spare parts, You are going to make mistakes, it’s how you handle the mistakes. We all will fall, it’s how you get back up that makes a difference. Thanks for showing everything and admitting that you are human. I look forward to watching more videos. A plus in my book. Amazing job. Keep up the great work….

[@AnthonyBowman]

Here's you turn that frown upside down by changing your perspective: DO make the BoS significantly larger. Almost comically so! As you learn and progress further in your already incredibly skilled craftsmanship, the size of the box should grow too, as a reminder to stay humble and check your assumptions. Then, even if you have a steady contribution to it, the sum total of those contributions still looks relatively small compared to the box itself. That mirrors the relationship of the value of learning you get from the mistakes compared to the relatively minor and small size of the scraps of metal mistakes in a corner of the box. Maybe a bit philosophical, but that sort of vibe feels somehow right with how your channel and content comes across, which I love so much.

[@CuttingEdgeEngineering]

Very nicely done mate! Your attention to details is next level and always striving for precision and perfection. Not sure what it says that our spare time is spent watching other machinists machining 🤣 Cheers, Kurtis 👍

[@InheritanceMachining]

Oh so you're just like the rest of us then! 😂 Once a machinist, always a machinist. I really appreciate it, man!

[@rodrigotomita6473]

It would be very nice to see Kurtis doing a monster knurling tool to knurl the cilinders of heavy machinery. Just for fun 🤣

[@cryoine7194]

funny enough i was just watching your new lathe tool post video and couldn't help but think what would inheritance machining think about it

[@nyssfairchild2244]

Often the best way to become a better writer is to read. The principle absolutely applies to machining and other skills.

[@joshclark44]

I'm glad you showed the proper way of knurling by calculating the right diameter first. I actually haven't seen that yet in other machining videos but knowing how gears worked I figured some math is involved to get the perfect knurl and have the lines match up instead of just mashing it in till it looks half decent. This is much better and you don't get all the near misses between the lines like if you mashed it

[@InheritanceMachining]

That used to be my method and I always had to do "test" knurls on areas I would eventually turn away. The calculator I used is great and so far on a few parts had been spot on.

[@chrisstephens6673]

Someone did a test once and it made no difference whether you calculated a precise diameter or not. It is a swaging process not a cutting one like a gear. If you have a cutting knurl, yes they exist, then a precise diameter is required.

[@theroundtomato]

yea as a machinist I have only probably had to knurl parts for a few dozen jobs but usually we just go for it and hope it comes out well since knurled features aren't usually critical and as long as its not very corse knurling it usually works out, sometimes needing a little adjustment in diameter. I didn't know a calculator existed online for knurling but ill definitely try it next time and probably use it from now on. super cool.

[@wolfiemuse]

@@InheritanceMachining this is also my method up until recently but I hadn’t found a good calculator I liked on the internet. Glad you make the videos you do, man. I know I’ve said it to you several times already about knurling, but it bears repeating: they always look great

[@snifflesfpv7321]

People have knurled tapers before, so diameter isn’t as important as one might think, but it is more intuitive and probably gets more consistent results to calculate the exact diameter needed.

[@JGV_IX]

I don't have a metal lathe, nor much machinery at all actually...BUT I want this!! I'd put this on my coffee table, have it in the kitchen when I cook, casually leave it on my car's dashboard - all so that people can gawk at it 😱 Really well done!

[@TGC32]

You're quickly becoming one of favorite manual machining channels. I like that you show the entire process including the mistakes. One critique I do have here though is I feel that A LOT of the mistakes you make are minor. Minor in the fact that they are completely avoidable in most cases. While I was doing my tool making apprenticeship I had a very large fixture that needed to be machined much of it manually. I spent 3 or 4 full shifts working on what I thought was a masterpiece. I was so proud of it as it was a very complicated fixture with a lot going on. After I was finished I put the customers part in it to verify everything was in the proper location and it was going to work. Well everything fit but I noticed some major features slightly off. I couldn't for the life of me figure it out. I told my boss and said "hey Its all finished but something doesn't seem right. Is the customers part out of spec?" We checked it and it wasn't. What I failed to realize was the datum for the drawing and dimensions worked off a centerline and not a corner. What did I learn that day? ALWAYS READ THE DRAWING FIRST. Over and Over. Now I have a dedicated cart where my drawings sit and before I ever even take a first cut I verify my first datum or location point. ALWAYS READ THE DRAWING FIRST!

[@BrilliantDesignOnline]

ahh, the CoS, Cart of Shame 🙂

I’m an ex electro mechanical engineer who had a nervous breakdown and as a result have areas of memory loss. Love watching your channel as it reminds me of better times. Keep on using the eyecrometer my man, every prototype engineer depends on it.

30 years ago when I young started working as a toolmaker, my master Håkan who saw promise in me said: "a good toolmaker isnt a toolmaker who never makes mistakes, a good toolmaker is a toolmaker who can fix his mistakes!"

[@PracticallyMint]

Sometimes I think I learn as much from the mistakes as I do the rest of the project… so I am also glad you have opted to keep them in there. Gives me hope

[@mashrien]

My one and only complaint about this channel is that this dude doesn't upload frequently enough. This channel, Cutting Edge Engineering from Australia, ThisOldTony and occasionally Abom, are my machining crack.. but y'all don't upload nearly often enough ; ;

I can't help but feel that's partly my fault- I bugged Kurt machine tools, got a hold of their HR department, and convinced them to send TOT a HQ Kurt vise. He declined it in the comments when I mentioned it, and that was the last video he put up for a while I believe

[@mashrien]

Addendum; he declined it because he was worried about impartiality and his viewers thinking poorly of him for it. Which several other commenters and myself all impressed upon him that would never be the case.

God damn do I love this channel so so much. Thanks for all the wonderful content, thoughtful commentary, delightful humor, skilled craftsmanship, earnest humility, and soothing presentation. Easily, and by far, the best machining channel on KZbin, and honestly, of the 500+ channels I subscribe to, 350 or so of which are makers, builders, crafters, machinists, carpenters, and the like, this one is very much one of my 3 favorites. What a fantastic project!

[@InheritanceMachining]

Thank you so much Anthony. You are very kind!

[@MatthewMenze]

Any thought to making your own knurling patterns? I've always felt that the variations of knurling patterns are a bit under explored. For example, a single angled wheel and a smooth wheel could make a rather visually appealing spiral knurl...Which I have accidentally achieved before with improper setup causing uneven wheel pressure.

[@InheritanceMachining]

That's an interesting thought. I've seen variable angle cut knurlers that will sort of let you change the angle of attack giving different results.

[@Clough42]

I feel your pain. :) It's a nice tool in the end, though. When I attempted to knurl the cap, the arms would not clear the shoulder. I wonder if hitting the shoulder is what caused yours to go awry. I can't see any mistakes in my dimensions, and it seems impossible to knurl up to the shoulder as shown in the drawings.

[@InheritanceMachining]

Thanks! Yeah I had that issue as well. There wasn't even a dimension given for the width of that non-knurled area. I ended up just going as far as I could without the arms rubbing the shoulder and clearing the rest. Visually looks a bit less than the drawing but works fine all the same. Still watching through your build by the way. Got pulled away working on the next video. You know how it is

[@Clough42]

@@InheritanceMachining It looked like the end of the M6 screws were shiny in your video, so I assume you had to shorten yours, too? I mean... more than just to compensate for machining all the surfaces?

[@knightyyz]

A trick I learned when stacking two identical pieces in a vice is use some paper or cardboard from a heat treat tag/business card or something similar the length of the bars on the moving jaw side. Even if it gets soaked the bars are going nowhere

[@PatrickHoodDaniel]

You pencil drafting skills have improved tremendously! Even 3D and color!😁 If you needed to move the y axis 2.5 th, doesn't that also mean that the pin is off center as well? Before you shaved off that edge, I was thinking that the whole side of the part could be shaved off instead to make both holes and the slot centered. Or are they not supposed to be centered? Great build as always and I'm glad you are not afraid to show the mistakes. When I do this, I get a LOT of comments! Your threading looks better than every threading I have seen on KZbin. No chatter and very clean threads. How do you do this?

[@InheritanceMachining]

😂 If only! The hole I located off of was drilled on center in the previous operation. It was only when I re-clamped the parts to cut the slots did I shift the y axis. On the threading I usually try to run as fast as I can comfortably engage/disengage. Only cut on one edge of the insert adjusting the compound only. Then when I get close I take a lot of 1 thou and spring passes. This seems to help a lot with getting very smooth threads. And when they don't come out super smooth a small triangular file and emery cloth can help too. I appreciate the support though. For the most part sharing the mistakes and talking about what I did wrong is received pretty well. But I do get the occasional jerk or two. And I basically ignore the "Held for Review" comments 😂

[@PatrickHoodDaniel]

@@InheritanceMachining Excellent advice!

[@belatoth3763]

Why does everybody do scratch pass before threading? Even those people who I know has a magnetic indicator (K Rucker, Quinn Dunki...,). It is more precise putting it to the way to measure displacement of the saddle during a full turn of the spindle. This way I could find hundreds of mm pitch deviation which was caused by the small amount of opening the lock nut.

[@TheRecreationalMachinist]

Another awesome build! I can't help but think the stuff in your box of shame will still beat my best effort on a good day! And thanks for the link to the knurling calculator, I've been meaning to write a chart of go-to diameters that will give good results, and now I've no excuse! 👍 🇬🇧

The more I see you use your rotary table the more I have to wonder if it would be possible for you to build a small 3 jaw expanding chuck that fits inside your rotary table instead of making a new locating pin for every hole size.

[@skeetsmcgrew3282]

One question. You mentioned your knurling wheels have a pitch that limits what diameters you can turn. Does this mean you need a giant box with like 100 knurling wheels to be able to knurl anything?

[@InheritanceMachining]

Not exactly. In most cases knurling doesn't need to be an exact diameter since it's just for feel. So in the instance in this project the drawing called out a 0.438 diameter. But because of the wheel pitch I could only hit either 0.434 or 0.442. Either would have worked fine for the purpose

[@MarshmaloWarrior]

[@thedolphin5428]

Just an observation: Not just in this video, but in some others I've seen, you seem to make a lot of elementary oversights which have less to do with engineering and machinery but more to do with a kind of "rushing" mentality, maybe a kind of ambition to be "doing the next operation" before fully considering it. You agonise over 1 thou in tolerance but flip the part wrongly into the vice or forget to lock a handle.. Hmmm. A first year would not be doing that. As a boat builder, who must consistently consider up/down, left/right, in/out with expensive timbers unable to be re-machined in other ways, I sure couldn't fit (or afford) as many oversights as your B.O.S. contains. Its growing occupants seems to indicate "more care -- less haste". And fwiw, public self shaming (which you do so well) doesn't actually help in increasing the minute-by-minute awareness needed to lessen future mistakes. That takes more mental self disipline not be be distracted by ambition. Being "in the flow" helps. 😊. Great channel, btw. PS, Your comment "It's amazing what a little bit of sleep can do" is, to my mind, an inversion of the solution's truth -- which is, recognise tiredness and distraction *before* making the oversights and mistakes.

[@machobunny1]

I watch all the fun you have with that rotary table and I think. Hmmm, how much $$? OH HELL. Are they THAT expensive? Nuts. Back to the belt sander. That said, I am pretty sure that if I had to trash a part twice, I'd probably not be safe to return to that job for several days. On the other hand, running a camera, and lights, and thinking about all the details, and sound tracks, and all that goes with making these videos...it is SO easy to forget things. WELL DONE!!

[@bRad73016]

Brandon, for holding multiple layers in the milling vice, I use a piece of cardboard like from a cereal box behind the moving vice jaw. I keep a stack of these cut to the same dimension as the vice jaw with my parallels just for this occasion. I'm sure professional machinists (which I AM NOT) would disagree with this method but I've achieved really good accuracy when drilling holes through stacks using this method. It's certainly better than drilling them all individually OR having them come loose in the middle of your operation - THAT SUCKS!

[@t_c5266]

Something I always wondered about knurling. If you go around the same area, the pattern won't line up because the division of the rows on knurling isn't going to perfectly match the circumference of the piece. How does it seem to always perfectly line up? For example if you had a 1 inch circumference rod, and knurling every 0.15 inches, there would be a mismatch of 0.05 inches. Making one row either cut in half, or really ugly, wide, etc Edit: I wrote this before watching the video. Guess my question was answered 😂

[@philip_fletcher]

More excellent content to inspire me! I'm so pleased you show your box of shame - I've just made this ( kzbin.infoX-M8HZ1Hmns ) as my first attempt at very accurate machining and had to restart both the little pin and main body...

[@superdupergrover9857]

Um, I did only take a course, but my hand machining instructor said that it was unnecessary to calculate the number and size of grooves when knurling. He was right, too; I still have perfectly formed diamonds on the plumb bob I made. While not the same one, we all used knurling tools that operate on the same principles, albeit ours were more scissors like instead of like a gear puller as shown here. Furthermore, you can tell by eye when the knurling is fully formed, at least when diamond knurling. As the diamonds go past, oh, 50-60% formed, they start to look really rough as little burrs are formed by the knurling die swaging/skiving the material along each face of the diamond. This roughness gets more pronounced, then changes in texture as you get closer to fully formed. Suddenly you see a lot of swarf, as the knurling dies are now cutting off the little burrs. At this point the diamonds are past 85%, and you will need to pause frequently to check on progress. Once you get past 100% formed, you will see the diamonds have a sickly texture to them and you get this weird looking swarf, unlike what you see before. As students, we were running slow feeds and speeds and constantly bathing the the area in cutting oil.

[@ianday38]

I recently bought a cheap drill press vice which would struggle to hold up a day job as a door stop. I've spent several happy hours making parts to improve it by hand. I hit a similar problem to you with the screw not making good contact with the bottom of the drilled hole. The tolerances were a bit bigger on my project because I fixed it by dropping an M6 hex nut in the hole which took up the slack quite nicely!🤣 How about a cheap crap tool improvement project?

And these kits i am sure, dont come cheap, whereas i can get tool steel and bronze and most any stock for 1/10 the industrial price or even cheaper... Sure, as with that bar o` stock you reached for, its oft rusty and in need of some reductive finishing to get it into shape and size i need, but if i bought a set, and i was facing the fact that all the stock is once given a proper surface finish, undersize to what the design ordains, i would be furious, and that is one thing i try to avoid as often as possible, as it aint a sign of things going to plan... Paying for rage is a bad investment... If i want to be enraged, i can just turn on the TV news, which i haven seen in over a decade and a half now... Machining is supposed to be relaxing and meditative, not a source of bloody fists and explosive swearing...

I'm OCD enough to do this level of precision but ADD enough to lose interest halfway through the project 😂 Idk what this tool is for but I'm enjoying watching you make it

[@srck4035]

As much as I like your approach on things some things are just ridiculous. Doing round offs on a mill.. Just mark the radius and use a belt sander. If you did it a few times its the same outcome. Maybe not precise as milling but do you really need precision there. No. Also a good handcraft training :)

He forgot to chamfer the bushings. He's letting himself slip... Jokes aside, I thoroughly enjoy your videos. Keep up the good work (And chamfers)

[@brownh2orat211]

I've seen you fighting the twist in your lathe bed, take a look at this Keith Rucker video, shows a easy way to adjust the twist out. I had the same problem on my 1956 Leblond Regal and this took care of it. kzbin.info/www/bejne/a5O6oZp7obKgbsU

[@charlierobson]

Always a good day when a new video appears. Thanks!

[@InheritanceMachining]

My pleasure. Thank you!

[@littlebacchus216]

I'm a little confused as when making the slots in the guide plates you had to oversize one that was 'off centre' but when you said you were cutting the trunnion slot guides you "made sure they were identical" with one slot bigger would one slot guide need to be bigger. Now there are a lot of words in here I have never had to type before and I could just be missing where the adjustment was made. N.B. Thanks to you I know know that introduced stresses introduced into into metal stock at manufacture can have a marked effect on the final tolerances after working them.

[@madhukeshnp]

B.O.S says measure twice cut once.... Making multiple parts that are tiny and have small details are hard to make. I enjoy watching your content. I am a tool and die maker. But never had the chance to work on old school machines as CNC's took over these machines at the factories.

"Hopefully I'll get through without issue" OMINOUS FORESHADOWING

[@crabmansteve6844]

That is exactly what I do when I'm consistently screwing something up. I walk away and do something else for a bit, maybe get a coffee and some food, or take a nap. Works every time.

[@jimmurphy6095]

In case anyone is wondering... 9:54 is exactly where you're supposed to stop, wipe up the spilled beverage that came out of your nose, and hit the "like" button.🤣🤣🤣

[@bobuk5722]

H, Kudos for showing the learning cuts. Means that maybe I'll avoid those particular ones! I have this kit, it's awaiting me taking a brave pill .....

[@RealJohnnyAngel]

A few people have mentioned here and there in these comments that Diameter doesn't matter (that much). which is true in practice most of the time. if it weren't the top and bottom knurling tools wheels would need a linkage to track in sync. the trick to making it work seems to be counterintuitively going harder. taking a deeper bite on the initial pass. basically (and this may not be the actual reason, but it's the working theory) creating enough tool pressure to force the kurling wheels into the grooves that they've made. There are exceptions, but those are rare.

[@KeithOlson]

I, for one, really appreciate your willingness to show off your mistakes. This channel is basically 'Clickspring For Mere Mortals'. :grin:

[@markshort9098]

Knurling is black magic, the making the diameter a multiple of the knurling has been debunked by a bloke who successfully knurled a taper.. I normally just go for it and if the knurl turns out crap just turn it down and try again, it works out good more often than not

[@aguycalledlucas]

I need to inherit one of these!!

[@InheritanceMachining]

😁 You could make one!

[@enricodesign619]

Ohh i know the projects that takes days or weeks longer due to side projects and mistakes . Im in one right now, need new parts before om done, and its not next day delivery but weeks ... Ohh well then i have time to plan and make the rest better

[@supahonkey]

As an owner of a large machine shop, I highly recommend that you ditch the pin method in favor of using a dial indicator to sweep the bores. This will ensure accuracy, and you'll get faster with the sweeping method as you use it more.

[@mr.coolaid1004]

Your youtube videos are the perfect thing to fall asleep to such great calming videos

[@gabedellaira6924]

Used run an old cnc lathe. But had to knurl by hand. And having no training I got real good making it up. I had no idea you could do straight knurls. Or that there was a science to knurls. It always felt like bla k magic any time I did it

[@Kilohercas]

why you did not use heavy oil on rotating surfaces? It would give more premium feel !

[@chriscmoor]

The "Box of Shame" cracks me up. I'm pretty sure I'd need a muuuuuuuuuch larger box.

[@InheritanceMachining]

That just means you're more experienced, right? 😁

[@chriscmoor]

@@InheritanceMachining Just a whole lot older and not nearly as skilled.

[@MrSky084]

I made a clamping knurler (courtesy of Tom's Techniques) some years ago. I haven't used it yet.....Nice job.

[@bobweiram6321]

The human brain has a real problem detecting orientation because it's such a primitive operation, it abstracts it away. I wonder if other animals can do better considering their brains are less optimized for high-level abstractions.
