- A sticky subject for me… rotary broaching. I thought I had it figured out. But maybe not. So let’s build one not from my imagination this time.

If this project was my smallest to date, then it only makes sense that the next is the LARGEST!
build a lathe
Yes indeed
Damn are you going to empty your box of shame? jk
The box is definitely not named well. Box of treasures would be a better name, considering how much we all learned while it was being filled!
😳
HECK. The playdoh bit made me finally understand how those things work. GENIUS!
right? i have never understood the wizardry of the broach until now.
I still don't get how its cutting... The playdoh just gets push out the way in the example.
yup that was a really good call, I sometimes use plasticene to check what hammer blows I need for blacksmithing but I would never have considered it for machining
@@thegoldenatlas753 its a lot like a shaper or wood plane where the cutting edge slides across the metal/wood cutting a shaving but the broach cutter just moves forward more slowly
me tooo xD
Due to your videos I now chamfer my cheese before putting it back into the fridge. They're fantastic
😂 Thank you
Best comment of the day award!
Oh yeah, that’s the helper tax whenever I grade Parmesan
I think that I will steal the phrase "chamfer my cheese" it is just too good
"You're making it weird" sliding up while he slowly pops that bar in and out had me laughing so hard. I love the comedy bits interspersed throughout the videos.
And it was 2 minutes after admonishing himself to not bust through the bottom too fast. He knows his audience
@@zildjianbabyYup!
And now all of us know what Machinist Porn is...
😄😁😆😅😂🤣
We now know his "search" 😳🤣🤣
I had headphones on so I heard everything.
EVERYTHING
Surprised there wasn't some Barry White over the top..
I felt that breaking carbide boring bar in my soul.
That little click of failure echoes forever
😭
You need to make some holders for those small carbide boring bars.... a missed side project methinks...!@@InheritanceMachining
I want to see a boring bar holding thin strips of a sliced junked circular saw to rescue those brazed carbide tips
@@adven999
No stranger to the snap here. Those looked like Micro 100 tools. That stuff is so nice.
I had always wondered how rotary approaches actually worked. That Play-Doh demonstration really helped me understand.
Who knew kids toys could make it more understandable 😂
@@InheritanceMachining Is it primarily plastic deformation or by cutting action at to "top" corner/face (or perhaps some combination of the two)? If it's mainly by shear, I imagine you have to really slow down the feedrate so you don't outpace the broach, right?
@@MacroAggressorShould be both of it's working correctly. If you want to break it down, imagine the behaviour of a 1 degree slice of the action in cross section.
Calling out "the two jankiest bolts I could find", then making two bolts to satisfy the notion of Eric's desire to see some bolts made, then explaining that those two new bolts would replace the janky ones, is some grade A Chekhov's Gun setup/payoff. 👍
If only I had that foresight. Those were literally the only bolts I could find!
I saw it coming. It definitely had that foreshadowing tone.
Yep, and the mini boring bars that should be used for a long time...
What always amazes me the most with these projects is the sheer number of tools that you need to make tools. AND you need to know exactly what the best combo of those tools is, to properly create a setup that will let you make the other things. Figuring out how to get things positioned to machine a precise angle is always magical to me.
Once you do it enough times it kinda becomes a second nature, plus you kinda build up a collection of clamps, blocks, and angle cheat codes. Basically as you make a thing to solve a thing, you should hoard the thing you made to make the thing.
To be fair a lot of tools i use are just because I can. There are multiple ways to skin a cat, especially in machining. There are whole gangs of people that make everything with just a lathe. Including parts that are milled!
@@InheritanceMachining Why do those ‘gangs of people’ use lathes for milling?
Because they’re lathe-y… 😂
@@wayngoodman3099 😆
as a european I appreciate you telling us the metric sizes of (some of) the parts! Would be a nice addition to have that in every measurement, maybe added in the editing stage?
@MatthewSmith-rl5ox NASA used the metric system, joke's on you 😂
@@MatthewSmith-rl5ox I hope you're joking haha
not in the 60s @@original_snipod7812
As a kiwi I'm pretty much comfortable with both so long as its thou not fractions. (39/64ths ? 😢)
Yeah, just some text on screen is plenty.
The addition of the drawing when you were doing the internal boring was a GREAT and helpful addition. I think clickspring does similar and it really does help with the additional context!!
Nice! I'm glad that came across how I hoped. Thank you!
Don't cry, man. We are here for you. :)
No, go ahead and let it all out! We could all use a good cry once a week, I think.
I never understood how a rotary broach worked, until now. I learn something new with every video you put out. Thank you!
Playdoh for the win! Thank you
I had only understood when someone else did a similar project (though I think bought the entire thing) and used it on a mill. I think it was a square hole that was being broached for a keyway with a hole that was later being cut out
You channel is so damnably satisfying, Brandon. It gives me such joy to see a new upload. Exactly what I need after a stressful week of work. Thanks so much for the care, attention, humor, technical skill, and humility you show. You really do have something special going on with your work and videos. Thank you for sharing with us!
Absolutely my pleasure, Anthony! Thanks for always being here
Wanted to say, I absolutely adore your video-specific intro teasers. It comes across super polished and always gets me a bit hyped and curious seeing the highlights.
My wife appreciates this comment especially 😁 Those are her creation and idea!
THANK YOU for using metric! Finally your measurements mean anything to me!
Yeah these weird americans use hamburgers and what not for meassuring but the metric system
Easily the funniest machinist on TH-cam
*this old tony has entered the chat...*
Have you not seen This Old Tony, ahem.
*this old tony has entered the chat*
Oof don't let This Old Tony hear that
Don't let Old Tony hear you.
I’m just here to boost the algorithm. I love this shit.
Knowing where that one extra left out screw goes is already a battle that's been won! I usually have to spend 15 min figuring out where that goes (I usually deal with laptop and phone boards with different length, thickness and format screws). Usually left with few at the end.
For real... also sounds like the array of bolts you have around a small engine cover haha
YEY ! meter for the win, i finally understand the scale of what you are talking about !
😁 were my hands not a good reference? haha
Finally, someone has enabled me to understand how these crazy things work.
Can't wait for the side project that is making the box of shame larger.. also the fit that you made weird was completely understandable, every one of us would've done the same 😊
😂 that's what happens when my wife does the edits!
Knowing that its the new video day, I was refreshing YT to see when it shows up. At some point during the video, I noticed that the number of likes was 500 then by the end of the video it reached 1000. Now that's what I call a success. Congrats for all the hard editing work. Your videography and story telling are exceptional! Thank you for inspiring me!
Wow... that is nuts... I'm still blown away everyday by this channel. Thank you so much, sir!
Click the bell, then go to your profile, settings, notifications, and it'll alert you as soon as.
7:57 Using an inside micrometer with a rod to pick up the cut piece? Maximum respect!
Telescopic gauge, not internal micrometre
Hardening of steel is best done by dipping in oil than water after reaching a cherry red temp of around 900 deg C. It doesn't matter if that is used oil too, but a good clean new oil is always welcome. Annealing, on the other hand is done by dipping in water or just left to cool down to room temperature naturally. This is the method taught to me during my apprentice days at Bosch, Bangalore, India between 1981-1984.
That is true for much of the commonly used tool steel in home workshops, which is most often O1. (The O is for oil hardening). Also for many hi tensile steels including chrome moly grades like 4340.
However quite often tool steel is better served by a water quench (usually with salt added) such as with W1, or a cold air blast (eg A2, also HSS). In particular, steels intended for air quenching should never be quenched in liquid.
The playdough demonstration really helped! Thanks. In your last attempt I was soooooo confused about how it worked.
I'm glad! Yeah I didn't do the explanation justice that first time thinking most people were already familiar from ToT's series one it. I was wrong 😅
that cross section overlay is so cool! haven't seen other TH-cam machinist do that yet
Agreed!
This Old Tony.
@@BrilliantDesignOnline Thanks! Someone said they may have seen Clickspring do that too.
Oh my, it was only at the very end when you used the rotary broach in your mill that I finally understood how the heck it works. The rotary action is misleading. It’s all in the wobble! 😮 😂 Thank you sir. 👏👏👍😀
Before you made it weird, I literally made a delighted chirp while sitting alone in the kitchen and surprised my dog. Truly satisfying fit.
😂 I don't think I've ever chirped in my life!
14:15 is a machinists greatest moment
underrated comment
Wasn't expecting Brian to have such an accent. Really made me crack up.
Joining the "didn't know how a rotary broach worked until today" crew. These demonstrations are fantastic for the people that aren't familiar with machining!
Playdoh for the win!
I love the kiddo-friendly visualization.
You sir deserve a pid controlled heat treat kiln.
( The parts have gotten cheap too!)
Oh I know! It's on my list!
So excited to watch this, but I have to admit the broken tap in the beginning just makes me want to see that neglected tapping fixture that hides in the background get some love. :D
😂 i made a better one with that tap follower. I can't bring myself to clean that old fixture up!
"You're making it weird" we've all done it. Nothing more pleasing than that pop
Nice to finally see a video with units i understand completely. Lol, i kid, being canadian I do actually use both. Just metric makes more sense to me.
Hope everyone is taking care
🎉now you can make one at 1:1 if you can find bearing that work. Sweet build.
I think your grandfather would be so happy to you diving in and making all the cool tools and parts. I know I would be. 😊
😁 Thanks, Joe!
You can use a magnet to check the rigth temperatur for hardening steel. If its not magnetic anymore you got the right Temperatur for quenching
I absolutely love your channel. Watched 3 of them in the past hour after you were recommended to me. I bought a Bridgeport and Southbend lathe for the muscle cars I work on. Unfortunately we got nailed in Florida by Hurricane Idalia and I'm remodeling everything. My equipment, luckily had minor damage and watching your videos is getting me amped up to redo the mills again. Plus the lessons you're giving are top-notch. Thanks, Bob
Very well done !
what I find most amazing is that somebody thought it would actually work when they designed the first one
For real
Nice and relaxing as always
This Old Tony made a cool rotary brooch video too, happy to see more about it
Awesome content. I'm learning quite a bit here...
I work hard and revard myself with this video and sure enough, I fell asleep half way through. Got woken up by monkey howling and I now get to rewach the whole thing gigling at every oportunity guessing what did he break this time?
Fantastic project and video mate! Your editing is really starting to embrace the entertainment side of making videos :P
Just one note on rotary broach tools; you should grind a concave radius on the tip of the tool, similar or greater than the clearance angle you cut the sides at. This creates a negative rake angle on the tip and improves cutting performance massively. And some tips on hardening and tempering; keep the material cherry red for longer if you can, it helps the material austenitize properly, and use quench oil if you can. Water is rightly very effective, but brutally so if quenching parts with stress concentrating geometry. Brine is good middle ground (water and salt). And Tempering should be done at 2 hours minimum regardless of thickness, even though the scripture says an hour per 2,54 cm.
Looking forward to your next project!
Thanks for the tips!
AND kind words 😊
Silver steel is designed to quench in water......"Silver Steel Hardening
Heat slowly to 760 - 800°C using the upper end of the temperature range for lower carbon contents and lower end of temperature range for higher carbon contents. Austenitize until the temperature is uniform. Quench into well agitated water.
The approximate quench hardness is 65 to 69 Rc."
What a great project, and so beautifully shown!
Thank you, Ron!
One of the best yet!
Thanks to you I made it weird and now I feel weird!
I love how you have started to be more lively in your videos compared to how you were a year ago when I started watching.
I usually take a little while to come out of my shell 😂
love when you edit the image to show the technical drawing on the part as you bore the inside diameters, it helps understanding the whole process.
"Fffffffffffailure ... is good!"
Brother went straight from anger to acceptance! I felt that little snap in my neck.
😂
Great video as always! Would be cool if you did some sort of tutorial series?
Thanks! I avoid avoid sounding like I know what I'm doing. I still make silly mistakes haha
great project! surely you've already fixed the lathe misalignment?
These videos are so awesome! Everything from the crisp visuals to the fun narration makes it a blast to watch! Thanks!!
Thank you!
BTW, that was the best explanation of how a rotary broach works! Why couldn't anyone else just explain that only one corner cuts like that, rather than handwaving?
Admittedly my first attempt at an explanation (previous video) left a lot of people mystified haha
YOU MADE it werid by POINTING IT OUT!
The subtitles get me everytime! Are we talking about an Eric from Canada who talks about emotionally distant garbage?
When you are broaching the steel, it looks like the tool pushed into the jacobs chuck a bit. It might warrant making sure the shank of the tool is set back all the way so you arent just relying on how well the jaws grip the shank.
This is the comment I was looking for. For reference, its at 25:54
Good catch! I left it out for that aluminum test so I could access the shank screws but didn't find out it wasn't sufficient until the steel 😁
The clay demonstration on the lathe was a great visual!
Thanks!
"And for 'Most Educational Use of Play-Doh in a Machinist Setting' the award goes to....Inheritance Machining!!!!"
Would love to see a 2x sized one.
Thanks for the explanation of how it works! I didn't understand how it's different from just pressing a hex peg into a circular hole, but after you told that it's at an angle, it all really clicked together. I lvoe this channel.
What a really great demonstration for folk that dont know. Nice!
Thank you sir!
LMAO "you're making it weird" and the oh yea's was hilarious. Love your videos and your attention to detail.
😁
11:54 I built this tool and yes its very tiny. These mini threads right here eere the hardest part probably. Surprised i hit them honestly
using metric AND celsius in one video, this is a real treat. i just wish it were always like this 😔😔
The apron bit was *chef's kiss*
I "oooooo'd" out loud when I heard the first suction pop. So, no, not weird 😂
These vids are world class. After the little Play Doh thing, I FINALLY understand how these things work! Thank you!!!
At work I run a 4.5m x1 m x 1.5m bed mill cnc. Mainly making crusher parts. We started doing model versions of some parts for customers and industry shows. Doing parts that size were a challenge on my machine… fun though.
Nice work!Thanks for the look.
I love how you go through the effort of making metric threads when imperail would've done the exact same job
Your playdough illustration of how a broach works was brilliant! Keep up the great work!
Your work is so elegant.
That's by far the best demonstration for how a rotary broach works I have ever seen.
Thank you sir!
😂the post credit scenes just made me cry with laughter. As always thanks for a top tier video.
That 'pop' was very satisfying. Thank you for this moment.
As someone who manufactures solid carbide boring bars daily, it is good to see how they are used, even if you accidentally broke it in the process.
Hey, that's cool!
That is auto thumbs up for you sir!Don´t need to watch the video to know it is golden!Thank you sir,very much for these!
weird how i never asked myself how these hex holes are made. never would i have imagined you just force sharp edges down a round hole. not only that… everything spins!
your content is gold. thank you.
Much appreciated! I should mention though that there are multiple ways to make holes like that. And in the case of regular screws like the one i showed at the beginning, they are forged!
I've never machined anything and never will, but I knew I followed you for some reason... It "has to be at least three times bigger than this!"
that "kiddo friendly" example was fantastic haha really explains it as simply as it is
Thanks! I'm keeping the playdoh around for future explanations haha
Man, I felt that sigh at 4:17 in my sole.
Thanks for another awesome project!
The first few times I ever saw a broach being used it confused the hell out of me. It didn't seem like something that should work... but it did. Took a while before I was able to find an explanation that actually mentioned the freaking angle.
Comedy and machining. Feels like I'm back watching This Old Tony videos. Great work!
Finally some civilised measurements ❤❤❤
the editing to put in the overlay at 11:22 is amazing, would love to see more like it!
As usual I enjoyed your video. The playdoh was perfect to explain the process.
Thanks, Ben!
This video makes me really glad I went with a separate collet chuck instead of a drawbar setup.
that is quite the machinery that i did not know it would work like that
I enjoy your humor. I also enjoy your processes. Thank you for your efforts.
That was a very nice tiny project. Thank you ❤
Thank you!
The comedy in this video was top notch!! 😂
14:23 🤣 “you’re making it weird” just as I was thinking it 😏
Nice. I look forward to your videos now. Thanks for making em.
Thank you, Sir. My pleasure!
OMG the explanation was all i needed! for the longest time i was still wonderig what's the diference between rotary and regular broaching! i didn't know the angle thing
That 1 degree makes all the difference!
I have been watching all of your videos since I started my undergrad and PhD studying Materials Science and I just realized you also studied MSE!
Marvellous work, as per. Much kudos for even mentioning metric, just so good to hear.
😁 Thanks
14:06 I totally understand. Makes the words "wire, EDM" pop up in my head...
Awesome Work !
