I don't know why everyone had trouble seeing it in the lathe. I just set my phone up in the 4 jaw chuck and set it to spin at the same rate, it was perfectly visible.
you probably dont care at all but does anybody know a method to log back into an instagram account..? I was stupid forgot the login password. I would appreciate any tricks you can offer me!
@Harlan Rohan thanks for your reply. I found the site thru google and im waiting for the hacking stuff atm. I see it takes a while so I will reply here later when my account password hopefully is recovered.
Im one of those. I certainly missed something because i couldn't see how flats were cut by a spinning object.. now i see that the broach only spinning because the work was spinning. The chisel analogy makes much more sense.
@@daleroy2466 the very tip is the proper size, but behind that going up it has a taper to it - so as it wobbles the taper keeps the sides of the broach from touching the hole. Pause it once with the broach sideways and look closely at it - the sides of the broach itself are not parallel, it gets smaller towards the base of the bit. / \
I can only imagine the machinist who thought of rotary broaching. "Hey, you know that non-round hole that we need to cut? What if we try cutting it with a spinning, wobbly thing."
Here’s the thing. Pop the eraser out of a #2 pencil. Now, think, “How would I use this empty metal circle at the end of my pencil to make a hole in this sheet of paper?” I can remember in grade school when I discovered that I could make a good hole faster by wobbling than by just pressing, no spinning required. The only reason we need spinning in the broach equation is to [cleverly!] provide the wobble.
joke's on you, that was just some video trick. The spinnamathing was still spinning, it just spun the whole world with it so it looked relatively stationary. If you were in the iSS watching down, you'd have seen the world go wtf at the time.
Hats off to your wife, Tony. She was absolutely right. The lathe version i watched ledt me under the impression that the broach was spinning all the way through the cutting action. I was very confused trying to understand the mechanichs of the cut. Just chalked it up to Tony Magic. As a follow up question. Im jealouse that you have a wife that actually cares about stuff like this enough to accurately diagnose an issue of this sort. Kuddos to Mrs. Old Tony.
Wow! This answered a question which has been burning in my head the past 40 years. At a metalworking course, a fellow student had bought some neat looking electric pushbuttons for a project. The instructor looked at him, and said "Cool...How's you gonna drill all those square holes you need for those buttons ??"
This video is beyond rebroach. However, it's now clear: The real family machinist's identity has been revealed. She taught you well TOT. :) We all expect another installment tomorrow. Thank you!
I suppose I did understand the first video, though I was confused.. This definitely cleared it up! I would say you are a lucky man to have someone like Mrs Old Tony, but you seem genuinely awesome so you earned / deserve it!
these are a wonderful set of shots. i could kind of see what was happening in the previous video but this make it so much more clear, and there's something extremely satisfying about seeing an almost diagramatic, well shot take of the tool in action.
That's all pretty funny but I'd recommend that you don't pull on Superman's Cape -- you don't spit into the wind -- you don't pull the mask of the ol Lone Ranger and you don't mess around with Tony's wife
Omg... I don't know how I lucked across this old Tony.. But it's my absolute favorite watch ever. I always wanted to get into mills and lathes ..or machining I guess I should say..but was always to intimidated by it all...but This Old Tony has changed that brick wall of mine into a new hobby . thanks this old Tony.keep up the good work. Most entertaining
in the last video, the material spins, while the broach stays stationary. in this video, the table is turned; the broach spins in the spindle, and the material is held stationary in the vise. i don't know what sense those two observations make, but apparently the broach does not spin, in actuality, the 'spindling' (is that even a word?) action turns into 'wobbling' action on the business end of the tool, which in turn makes the cuts into the material and voila, hexagon shaped hole! now i get it. thanks Mrs TOT for the suggestion, and thanks Mr TOT for admitting your mistake and taking the time to make a new video with a new perspective, which drove the point much clearer. I must say, you're the man, and she's your lady. On another note, of all machining videos on YT, I find yours to be better than the rest. Why, you ask? probably your humor, your soothing voice, your thorough explanation of why things happen the way they do, and also when you make mistakes, they don't get edited out of the final video and we all know we learn much more from our (and others) mistakes.
Thank you TOT for clearing this up. I really didn't understand how and why this actually worked until now as I am NOT a machinist. I really enjoy EVERY video and learn a little more each time. Please keep up the GREAT WORK. You are too funny and make every video worth watching.
Great Vid! I was an industrial electrician, been around machine shops most of my life but have Never seen the broaching done. I didn't even know what broaching was, so it was very interesting to me. So you can actually put a square peg in a round hole... Thanks, Gary
ohhhhhhh, now I get it!!!!!!!! In the lathe, everything was spinning and dancing and cutting and I was wtfing. My understanding was almost as jumbled as my previous sentence.
For most of the last video, I honestly thought it was a gag that went on uncomfortably long. I was about to be upset when I realized, oh, this is a real thing.
I watched your 'Square Holes' vid first and while I knew what broaching was I had never heard of rotary-broaching (I'm no machinist) so when I saw you using your lathe to 'turn' a square hole I did two things... 1. giggle inanely and scream "Magic-ery", 2. once calm I went down the rabbit hole of finding more info on rotary-broaching (including visualization vids on clear acrylic blocks). This meant when I watched your main broaching vid I was perfectly fine with the reference-frame switch for the lathe 'method' and understood the 1 degree angle behind the broach face. This supplemental vid is just icing on the cake and really shows how clever rotary broaching is, thankyou for posting it, Captain Old Tony. End Transmission.
I got the gist from the previous video, but watching this one made me realize a few things I didn't see before. For one thing, the broach tool must be slightly tapered (maybe that should've been obvious). For another, the axial tilt determines the length of the broach tool. If you shorten the tool by refacing/sharpening it, the cutting face will not just precess but will also "orbit" off-center by a gradually increasing amount the shorter it gets, resulting in gradually expanding hex key size.
I'm no expert on this stuff. I would guess the broach sits in the bottom of the hole for cutting forces, I don't have one. Stefan Gotteswinter built one from a kit. Learn all about it in his channel.
I just figured out how to verbalize the confusion I didn't even realize I had after watching the last video. I use drills in the tailstock of my wood lathes (i know, i know...) all the time. When drilling, it doesn't matter whether the drill or the work spins, but one (and only one) of them's gotta spin. In broaching, the work AND the business part of the tool can either BOTH spin, or BOTH NOT spin. BUT there is a 3rd element, the body (?) of the tool where the 1 deg angle lives, and it must do the opposite of the work/cutter (spin or not spin). The fact that the work and cutter were both spinning on the lathe disguised the wobbling holder action. Wow. Thanks again, Mrs. ToT!
I can't believe you managed to put that many jokes over a 3:30 min long video. I know that depending on the task at hand you get more mileage with imperial, but to be able to abuse imperials to stretch the time-space continuum the way you did here is outstanding! And this was far more educational, seeing the wobble, and what the tool does. Please give my thanks to your wife for being so kind with random TH-cam strangers, that was really thoughtful :) .
Man I wish I had metalworks lessons in general high school. We had mathematics & physics instead, but becoming an engineer without solid experience in metalwork in a bit thin.
Ok, yesterday's video did have me confused a bit...but figured I didn't need any questions answered. This video though answers all my not asked questions. So thanks for providing the answer to my non question. Makes so much more sense now
agree, I thought TOT was messing with us yesterday when he first moved the 'fixed' broach into the rotating lathe head and thought wtf, that can't work ...and considering other tricks he has done ie karate chop bar stock, I just went for the ride. Then was confused that it worked...what. We needed this extra vid and it's awesome. Like others have said, I want one too
@@DanStone1025 yeah it was good...yet i had to cheat on TOT and go watch someone else's channel to get a better view of it working..his HD filming and humour is hard to beat
So 6 months experience in a machine shop and I’ve been watching your videos and a few others to help learn me something. Watching the last video I thought I had a good understanding of what was going on but this definitely helped me understand broaching, awesome work
Mrs. This Old Tony was right. I had no idea how that broach made that hole while it was in the lathe. This video explains it so much better! thank you for making this!
thanks for the follow up video i saw the previous and dismissed rotary broaches as wizardry ahah ps: im a really big fan of the effort that goes into your videos and the comedy you bring too such an overlooked hobby
Thank you Old Tony. Really good job, and I did not think so it first, but after having seen this one, I agree with your wife. This makes it much clearer. Thank you so much and please stay healthy and keep it up. Sincerely Alicia. Oh yes, one more thing. Your sense of humor is very, very appriciated! I have only found Oliver Motorized to be on the same level as you.
Damn! Forty years in the trade, and I've never even heard of a rotary broach! You learn something new every day! It took this second video to make it clear to me. Thanks so much.
You old wife was right. I did understand from the voiceover from the last video but the visuals from this one did a much better job at showing. Thank her from all of us.
I'm a complete novice (I don't even own a lathe) but I did understand better what was going on with a broach- while watching it in a drill press, IMHO. Thank you This Old Tony!
Your wife was right. Always good policy to listen to them. Lydia always has at least one good idea per project so I pay attention to them all and pick out the good ones. 😆😎
This is some cool stuff! I now work in a sheet metal fabrication shop where we make large quantities of parts for various companies. Your videos have spurred an interest in the inner workings of metal fabrication. Mostly I just push buttons on anything from 35 ton presses to 250 ton, all of which are probably older than I am. But today, I got to see a Surface Grinder in action, magnetic plate and all. Since watching your video about them I've wanted to see one in person! Now I have access to a lot of these types of tools even if I don't use them myself. The long and the short of it is, thank you for occupying my small brain with machining videos well beyond my capabilities!
Thanks for the time, effort, humor, time... 👍🏻👍🏻 I wish I had half your skills behind and after the camera as you demonstrate with really amazing tools and machines. 🛠️ Your videos are fun to watch, I hope youTube's new game plan doesn't discourage you. Thanks again. I'll probably never own, never touched one but always loved watching lathe work. A broach rocking through rolled steel in slow-mo was a grin generator. Cool, thank the Mrs. for us.
I understood your first explanation just fine and I'm drunk. I couldn't see the wobble but you still did a good job explaining how a rotary broach works. On the lathe it actually looked like the work was wobbling around the broach.
I knew how it works (honest) but this video captures it so well! You can really see how the relief angles work too on the broach. Very cool! Only thing cooler might have been watching from underneath and seeing it come through.
Man. For me it its kinda one of the greatest mysteries in the universe. Where do you find the energy and time to entertain people this way, while maintaining a day job, keeping a wife, take care of two kids and climbing rocks with a trial bike? You have super powers, thats the only possible explanation.
Build a rotary broach from scratch, please. Ok I know you have one, but I would like to learn how to make one, preferably from you. Keep up the awesome videos
I had never seen a rotary broach before your previous video. I had tried grinding a standard drill bit square but that did not work too well when you spin the bit. Still get a roundish hole.
Always listen to your wife, or at least pretend to. I'll be blissfully wedded 30 years next May, so I get the drill. That said, I got the first video just fine, but I'm glad This Old Wife gave you a reason to put out another quality video in such short order - albeit a short one. You really are the most fun and informative content on the TH-camz right now, hands down.
I don't know why everyone had trouble seeing it in the lathe. I just set my phone up in the 4 jaw chuck and set it to spin at the same rate, it was perfectly visible.
OMG That's SOOOOOO much easier than the harness and rig setup I used.... Could have kept my lunch too...

stuart pratt yes, there is a number in that factor, possibly an integer - unless there isn’t. Hope that helped
@@stuartpratt3662 I believe it's related to the Bob&Doug McKenzie metric conversion formula.
By the way that was the best demo of the action of a rotary broach I have ever seen.
out of how many? :D
This will definitely help all those people who were like "how the hell?" in the last video ... phenomenal demonstration of what it was doing. :)
I mean, I could reason out that that had to be what was happening. I just couldn’t see it.
@@JasperJanssen - same here. I knew it was wobbling, but to see how much it was doing so was cool. Very glad Tony gave in and made this one. :)
Im one of those. I certainly missed something because i couldn't see how flats were cut by a spinning object.. now i see that the broach only spinning because the work was spinning. The chisel analogy makes much more sense.
I'm still confused how it cuts it perfectly with that wobble. I guess the bit is slightly under sized for the hole it needs to make?
@@daleroy2466 the very tip is the proper size, but behind that going up it has a taper to it - so as it wobbles the taper keeps the sides of the broach from touching the hole.

"So what are we doing today, This Old Tony?"
Magic, but you can see it this time.
I can only imagine the machinist who thought of rotary broaching. "Hey, you know that non-round hole that we need to cut? What if we try cutting it with a spinning, wobbly thing."
Now I better understand that a rotary broach is made of wibbly-wobbly turny-wurny..... stuff.
This technique could have been discovered as the result of a "happy accident".
You called...
Here’s the thing. Pop the eraser out of a #2 pencil. Now, think, “How would I use this empty metal circle at the end of my pencil to make a hole in this sheet of paper?” I can remember in grade school when I discovered that I could make a good hole faster by wobbling than by just pressing, no spinning required. The only reason we need spinning in the broach equation is to [cleverly!] provide the wobble.
@@CaryMillsap Ha! I did not try paper... but I did have a larger eraser that ended up looking like Swiss cheese ;)
I think it would be far more interesting to make the broach stationary, and wobble the work+mill.
you must be an over-engineer? ;)
c'mon, you're not thinking big enough. Hold the broach stationary, and wobble the earth!
@@Touay. haha your hilarious
@@Touay. The earth is already wobbling, just gotta give it more time....
@@Touay. Earthquake broaching, perhaps? Not the Harbor Freight version, of course.
I especially liked the part when the spinny wobbly thing became a stationary non-spinny wobbly thing.
With an outer non-stationary wobble? Weeble wobbles wobble but they don't spin down.
joke's on you, that was just some video trick. The spinnamathing was still spinning, it just spun the whole world with it so it looked relatively stationary. If you were in the iSS watching down, you'd have seen the world go wtf at the time.

Bonjour, je suis complètement défoncé et je ne sais pas ce que je fait ici, merci bonne journée.
Cool! My drillpress has the same wobble since the day I bought it. Didn’t expect it to have a broach feature for such a cheap ass price.

Yes, the broach body is not just tilted, it is also offset to bring it back to centre based on a chosen nd fixed broach length for the tool.
@@michaelpiotrowicz6100 after sharpening could you set the broach cutter further out in the broach holder. or does it have to be set all the way in?

While I got the concept on the lathe, this was much more visceral. Love your stuff, ToT but the Wife was spot on.
Damn! Forty years in the trade, and I've never even heard of a rotary broach! You learn something new every day! It took this second video to make it clear to me. Thanks so much.
You old wife was right. I did understand from the voiceover from the last video but the visuals from this one did a much better job at showing. Thank her from all of us.
Two TOT video within 24 hours, feels like Christmas! 🎅
Oh and by the way, this video makes much more visible what is going on...
Got it the first time around, but I never say no to a second serving of This old Tony... :-)
same :)
Yup, it seemed easy to understand from the first video, but any excuse for another ToT work of art. :)
If only he had time to make daily or a few videos a week I would be living the dream lol
we should say that we still don't get it and need more example material to see more ToT content... ]:-)
It was entirely understandable. But it *is* nice to have it *visible*. it’s a visual medium here on TH-cam.
That clearified a lot . Now if you want one side in a specific orientation
Tony, please don’t stop making videos.you are awesome at this. Owner of a new lathe because of your channel!
Thanks for posting that, it's sooo much more visible. I'd grasped the concept of it in the other video, but seeing it is just so much better.
Captain's Log: Supplemental.
Stardate: Uuuuhhh...1!
My wife was right...again...
End Log.
Yeah, we all know who wears the admiral bars at captain Tony's star base.
Your previous video on rotary broches seemed fairly clear to me, but this one does show it better.
It's rotoring AND its broachering. NOW I GET IT!
tysm, Mrs. TOT
Sometimes it’s the short videos that teach us the most! This one blew my tiny little mind 😱 thanks TOT. From an official TOT T-Shirt owner 🙃
I'm a complete novice (I don't even own a lathe) but I did understand better what was going on with a broach- while watching it in a drill press, IMHO. Thank you This Old Tony!
Thanks for makin'!
Yep, you owe her a beer for sure because on the lathe, it doesn't show what's happening at all. Now it all makes sense.
Your wife was right. Always good policy to listen to them.
Lydia always has at least one good idea per project so I pay attention to them all and pick out the good ones. 😆😎
Never admit they aren't all good ones!
Metalworking belly dance! Yay!
There is my comment!......Well wish it were mine....*sigh*
This is some cool stuff! I now work in a sheet metal fabrication shop where we make large quantities of parts for various companies. Your videos have spurred an interest in the inner workings of metal fabrication. Mostly I just push buttons on anything from 35 ton presses to 250 ton, all of which are probably older than I am. But today, I got to see a Surface Grinder in action, magnetic plate and all. Since watching your video about them I've wanted to see one in person! Now I have access to a lot of these types of tools even if I don't use them myself.
The long and the short of it is, thank you for occupying my small brain with machining videos well beyond my capabilities!
Thanks for the time, effort, humor, time... 👍🏻👍🏻
I wish I had half your skills behind and after the camera as you demonstrate with really amazing tools and machines. 🛠️
Your videos are fun to watch, I hope youTube's new game plan doesn't discourage you.
Thanks again.
I'll probably never own, never touched one but always loved watching lathe work.
A broach rocking through rolled steel in slow-mo was a grin generator. Cool, thank the Mrs. for us.
I wish I could have a trip in his shop and learn couple days working with him! I suspect it would be both fun and formative!
This is soooo much more obvious now...
Last video I was like: Rotary Broach... but... it doesn’t rotate?!
Maybe I shouldn't have replaced those spindle bearings on my mill 😁
Probably still cheaper than a broaching machine
Much better, the broach spinning in the lathe looked like a special effect, this just looks like what it looks like.
any woman who gets us back to back TOT videos is a good one!
You're so lucky to have such a clever wife TOT. You really should listen to her more often. ;)
Your wife was right. Honestly thanks for the follow up video. This makes more sense now
I have had to do the same with my customers, they can't believe their own eyes! 😆
Wow I understood your description in the last video... but this illustrates it so much better :)
Yup! Good follow up and no one mind a "Captain log, supplemental."
Thanks you, and your wife, for showing this. I had a good idea of what was going on from the end of the last video, but this certainly made it clearer
I understood your first explanation just fine and I'm drunk. I couldn't see the wobble but you still did a good job explaining how a rotary broach works. On the lathe it actually looked like the work was wobbling around the broach.
Your wife obviously should be making these videos for you. Now I understand how it works. Thank her for me.
I need one of those air release chucks,.
I'm going to assume you made yours, can we have a build video on that? ,😁👌
Yea...if you stand on one leg and spin at 750 rpm...you can clearly catch the brooch wobble.....just be careful stopping.
I knew how it works (honest) but this video captures it so well! You can really see how the relief angles work too on the broach. Very cool! Only thing cooler might have been watching from underneath and seeing it come through.
2 TOT videos in two days? I've died and gone to heaven.... This will only temporarily stop me from rewatching the rest.
Wish my mill was equipped with pushbutton tightening/release.
Oh wait, I don't even have a mill. :(
Thanks for video, Tony!
He nearly got me with that...
I've worked on a Shaublin before...and it's very, very nice, but I don't remember that feature.
I have the same problem with my mill as you!
So, when can we expect a "Rotary Broach: Lookin' Sharp" where you unveil the mysteries of scrap end mills to broaches alchemy?
Please thank the wife.
I understood the explanation but seeing made me believe it.
Very nice filming, now you can see how it Works.
Thank you for all your videos, they make me able to do many things in me home workshop
Man. For me it its kinda one of the greatest mysteries in the universe. Where do you find the energy and time to entertain people this way, while maintaining a day job, keeping a wife, take care of two kids and climbing rocks with a trial bike? You have super powers, thats the only possible explanation.
Now I get it! Wait, I got it the 1st time you did it 😁. Love you Tony🤗
A TOT video and comment by Steve Summers, nice. You two should do a collaboration, like half machine a part each. Only better than that.
Build a rotary broach from scratch, please.
Ok I know you have one, but I would like to learn how to make one, preferably from you.
Keep up the awesome videos
Also, can you solve world hunger. Thanks.
I had never seen a rotary broach before your previous video. I had tried grinding a standard drill bit square but that did not work too well when you spin the bit. Still get a roundish hole.
Always listen to your wife, or at least pretend to.
I'll be blissfully wedded 30 years next May, so I get the drill.
That said, I got the first video just fine, but I'm glad This Old Wife gave you a reason to put out another quality video in such short order - albeit a short one.
You really are the most fun and informative content on the TH-camz right now, hands down.
I Always wanted to know how they Made Torx or similar screwheads , thanks tot.
I'm going to assume that commercial ones are just forged.
