Rotary Broaching Eccentric Cams || INHERITANCE MACHINING
Welcome back to the machine shop for the dramatic conclusion to the rotary table chuck adapter build! Two videos ago I went about the process of reverse engineering the D1-5 cam mechanism of my metal lathe and developed an adapter design using the drafting table. Then in the last video I underwent the emotional rollercoaster that was machining the main body. So in this video I’ll be finishing up the remaining bits and bobs to make the mechanism work. Along the way I’ll be trying a few new techniques including scallop milling with the boring head. Turning an eccentric cam profile with the 4 jaw chuck. And one of the biggest side projects to date, making my own rotary broach to machine square holes!

Once again my wife, Paige, deserves all the credit for setting up the highly requested merch store. She did an amazing job on all the designs! See the description to check them out. As for the next project, it will be one I've alluded to almost from the beginning so I'm excited for a much needed improvement. So look out for that at 10am EST on Friday Sept 30th. And as always, thanks for the support!
Next side project: Eccentric V-block chuck 😜
If I support you on Patreon I get the video on the 29th?
@@tigererickson8375 Yup, that's right!
@Gabriel Marshall I'm a lucky man!
@@OB1canblowme I'm already working out how to make my own 😂
for such a a recent channel i feel like you really captured the formula of what a great video is. Beautiful shots and excellent narration.. Congratulations and keep up!
With a sprinkle of jokes and pinch of recurring themes.
Formula's here. The execution however, leaves nothing to be desired except a larger library.
Thank you very much!
Nothing else has so quickly become a favorite channel. It’s amazing how good these are!
The same charm as TOT
The broken broach was so painful. Then the subsequent 5min operation on the mill to finish that operation of the 5 cams was . . . well, hilarious. Well done again sir. I love this stuff.
I could have been worse I suppose 😁 Thank you
@@InheritanceMachining to be honest I was interested in why you needed the corners to be so sharp for the function in the first place; I've regularly 'designed' square drive (or hex for that matter) parts intended to not require broaching so they can be milled instead, especially when we're talking such a short run of parts (or if non-standard sizes).
@@Avram42 It was mostly a bad assumption on my part. I assumed I needed a fairly sharp corner for the wrench to fit and didn't consider that the corners would be rounded. I was also excited about (and stuck on) the idea of making the broach. You live and you learn lol
@@InheritanceMachiningI'm not a machinist (but I dream of having a mill and lathe... and WTH, all the rest of that stuff to tinker with, because: why not).... but say you needed to have those corners sharp. Could you perform that milling operation (to hog out most of the material) and use the broach to cut the corners? Would that process lessen the forces on the cutting tool?
@@TheDesertRat31 that is why you are supposed to drill 10% over sized like he did after trying flat to flat size drill and it didn't work, you can drill out more to lessen the forces involved though but that would decrease the engagement surfaces, the problem whit milling away material to make a none round hole would be ensuring the broach engage correctly which is not impossible though finicky I assume, I may be wrong about this though,
This channel is great! I've been missing TOT, and this one scratches that itch. In fact, both creators have similar sensibilities regarding a focus on the work rather than their mug always being in frame, as well as using narration to explain the project. It keeps it all concise and on point. Personally, I would love to see a collaboration, as these two guys could be hilarious together with their subtle humor.
Yeah, I love this channel, but (and no offense), TOT is the GOAT at dad jokes.
God bless "this old tony"! Life must be getting in the way of more of his content. I hope he is doing well.
We all miss TOT. Thanks for stepping up to the plate
Thank you for your comment about other KZhead creators having their mug in frame CONSTANTLY. It's so annoying when you see this on other channels. For those of us who watch machining channels, we all know the one guy who is the worst at that. It's like he has to have his round mug in every shot while talking incessantly. Ugh....
I took the decision to be a "faceless" channel mostly because of liking Tony and his terrible jokes and film-star hands. I can understand why some machining creators just talk to the camera. It's SO much quicker than having to create interesting and engaging B-roll content, animations and then overdub and synchronise the narration. Keep it up Brandon, this is lovely gentle entertainment. Nice merch too.
The best part of finding a great new KZhead channel is the excitement of the first video released after you binge the archive. The worst part is the sadness when that video ends and you have to wait for the next one. 😭
Yeah, but that is what makes life interesting. Combine it with a few other good channels and you may have a steady flow of excitement.
Its become one whwre i constantly go back and rewatch the videos
I consider this channel to be on par with "This Old Tony", "Sampson Boat Co", "Mike Patey", "Fireball Tool", and "Stuff Made Here". I love that you all take the time to share your work with us!
Thanks for the suggestions, only knew of this old tony and fireball tool.
you would probably enjoy CEE too then, Cutting Edge Engineering.
Those are some big names (and some of my favorites). Thank you so much!
@@enetheru ive started using "dramas" in place of problems lately. Took me a while to figure out were I picked that up from. Clued in the other day it was from that dam aussie
If you aren't already familiar, check out Blondihacks too!
One thing i really like about you is that you show your mistakes and always try to learn something new along the way.
Branden, there’s a reason why your channel is growing so fast. You make great videos!
Thank you so much!!
Friday = Inheritance Machining and Saturday = Blondie Hacks. Always a good start to the weekend!
Side-Projects are love. Side-Projects are life.
The complicated things are what make it exciting! Broken tools included. Though they sting for a bit 😉
Your channel has quickly become one of my favorites. Thanks for sharing with us
I love to hear that. Thank you!
I love your side project counter in every video
As if the project, the side projects, the narration and the bloopers weren't enough, this video had FRIGGIN' FINGER GUNS in it!!!!!!!!!! Thanks for this one - along with the latest video from Torbjörn Åhman, this made for a wonderful, calm evening.
but man... they felt so dorky! 😂 But seriously, thank you so much!
It really is a beautiful thing that you are carrying on your grandfather's legacy through this machine shop. Most people would have posted the lot on craigslist. Thank you for taking us along with you on the journey I always light up when I see a new upload! keep up the good work sir!
I wasn't about to let that happen. I couldn't image giving up my grandfathers tools!! Glad you are enjoying the channel! Thanks for the support
I'm really proud of you. Learning from experts is great but watching someone grow themselves is cool too
I appreciate that! I try pretty hard not to come off as an expert as I'm definitely not. I just want to share the story of learning the hobby
@@InheritanceMachining You’re the best manual machinist I’ve seen on KZhead. And it’s obvious you’re an expert in engineering and more than capable of creating the parts you design with very high quality and precision. Love the videos man.
Perfect timing. Managed to get the kids down for their daily nap. Now for some relaxing time with IM. I love the channel, especially watching the board work. This has fast become one of my top 5 channels
Woo hoo! Thank you!
Love your videos. No frills, all the important stuff and just some wit to it. Good job.
Whats that old saying, "trying new things is how we learn new techniques", lets also not forget, "Failure is the best teacher"
I seem to embody these phrases
The politically correct term for "bad decision" is "alternative modeling, simulation and analysis." Love the channel and I am always learning. Many thanks
😂 love it! Thanks!
Geez, that reminds me of my time as a research machinist/contractor at NASA. Some of my 'customers', researchers and civil servants had all these big words and acronyms only they understood to explain their incompetence and justify their existence.
Very well done. Also fast becoming a favourite channel. Looking forward to seeing that heat treatment process!
just binged through all your videos and absolutely love them! Keep up the great work!
You must have had an early morning 😉 Thank you!
Well done 👍👍👍Thank you for sharing. Take care of yourself, be safe, and healthy 🇨🇦
the best projects are about repairing something that broke while making something, that could eventually find a usecase in a different project. But mainly its working for the workshop. Amazing
Excellent work and a very handy addition your workshop.
Simply Awesome! We absolutely love your channel and now I have so many new projects to try and machine because of this channel, I’m definitely not complaining 😁
I am continually amazed at the incredible detail in the process you follow. Just doing one function out of sequence can ruin an entire project or prevent moving forward. Your expertise is greatly appreciated by us all.
I watched the video a long time ago. Didn't know what it was though, until I was looking for a way to quickly change the chuck for my small lathe, I didn't know it turned out you had made one. After watching it many times, I finally understood how it works. It was so much fun. Thank you for the video.
Oh that's awesome haha Thanks!
That is a work of art mate!
I am a woodworker and absolutely enjoy your videos. I had subscribed to your channel and binged watched your videos. Good luck in your endeavours.
Thank you!
As always thanks for making the episode. I see you in the next one!
My pleasure!
Love your video style and the way you work with calm and precision. I also like how you emphasize that the main project carries many side projects with it. Thanks for sharing you passion
Thank you! I'm happy to share my journey
This was an awesome project. I'm not sure you captured just how complex and critical every measurement in a camlock design is. You made it look easy. I wish I had the patience to make one myself!
1 IM side project = 3 part ThisOldTony mini-series. I love it.
I didn't even know what a rotary broach was before ToT's series!
That "or... not?" moment when using your backup plan. My jam is woodworking but I felt that to my core.
Hell yeah, man, that rocks.
The rotary broach replacement was cool. Very good.
Kudos for having the courage to share that Dremel+hose clamp rig. If it’s stupid, but it works…it’s not stupid.
absolutely love the specialty dremel holder. This Old Tony would definitely approve.
Impressive! That was a lot of work
".. added a whole other level..." Mate, you've done that alright. Superb stuff.
Brilliant stuff as always. And the shirt has the drawing on the back, lovely!
Every time i see a rotary broach in action i am amazed with what they do
Very cool. Beautiful output.
This is deffinately a very well put together channel. Just found it a couple days ago.
That cam detent gave me goosebumps!
Lovely ! One of the better channels I've found recently :)
Thank you 😁
first youtuber merch i’ve bought and i couldn’t be happier supporting such a great youtuber. brilliant project and video, IM- keep it up
I love to hear that! Thank you so much for the support!
Ah. I have been watching this process with my morning coffee, enjoyed every minute 👌 True craftmanship with all its modest complications.
Thank you!
Nice work as always. I really enjoy your videos. Thanks.
Your narration, shooting and editing is getting even better. You're absolutely awesome. Thank you for sharing all those wonderful moments with us!
Getting a little better with each video 😁 Thank you so much!
I love your format. No annoying music in the background, and your bumper music fits your style and personality perfectly.
Why thank you 😁
11:56, great product introduction. I was literally thinking about how cool that shirt is.
Discovered your channel last week binged every video and jumped in excitement when i saw this upload. Love your content, the pacing, the shots, the vibes. Hope you have fun making the videos!
It's a lot of work but definitely still fun for me. Honestly the videos are probably helping me get out of my comfort zone. I appreciate the support!
very good job..thanks for your time
This was phenomenal. Keep the videos coming 🤩🤩
i have small fabrication shop and I love to watch maching process it's very setifing to watch, and your videos are awsome , waiting to see next video
Good on you for the persistence!
The end result is fantastic, and the journey and the video making was just as fantastic. I really hope you don't get bored of making these any time soon. This is my favourite channel right now, ToT and Clickspring have slipped a notch.
😮 Not ToT!! haha I really appreciate that man! Thanks for following along
I second that message, this is so nicely filmed and great voiceover. I'll be "borrowing" one or two of your editing and filming techniques!
I really enjoy all your machining adventures, keep em coming I can't get enough. Also your narration is top notch.
Thank you so much!
I love your attitude and approach to work, problems and solutions. 🤗
thank you! 😁
Excellent workmanship. Your attention to detail is first class.
Much appreciated!
Very nice videos on the channel. Same as Blacktail studios. Sped up videos, comments to guide us through, showing the mistakes and issues along the way... I like it.
..... the difference Between making tools... and using tools...🤌 bravo 👏 👏 👏
Beautiful work...!
As always great job buddy. Good to see the wife's having fun in the shop with you. God bless
She stops down every once in a while 😁 Thanks!
What a great start to my weekend! Thanks very much for your hard work, we're spoilt by your production quality.
Now the pressure is on to maintain it! 😉Thanks!
@18:14 Soooooo satisfying! Great work!
As always, nice work!
Excellent job man, great video, keep'um coming..
Coming home from work, grabbing some food and a beer, then sitting down with a couple of your vids, has become my zen. It's so enjoyable, it's downright therapeutic. I love the attention to detail, and your adherence to tight tolerances; even for parts where it doesn't matter. With a few anomalies, when you can talk yourself out of it. I can see myself so much in that philosophy - I had to quit working construction because of it; I'm too much of a stickler for precision for that line of work. Your calm narration combined with your subtle humour is the icing on the cake, built on great craftmanship, videography and editing work. I hope you keep making videos for years to come, I intend to watch all of it. Thank you so much for making great content.
I really appreciate your kind words, Drake. I plan to continue this as long as possible. Thank you so much!
Excellent job!
This channel helps me relax
Outstanding as usual.
Its always a pleasuere when you encounter a quality channel like like.
Very well done.
Love the side project graphic. Great video yet again!
Thank you!
great work, the results are stunning!
thank you!
Great editing and narration. Very enjoyable! 😃
Thank you!
I do enjoy the videos! Thank you for taking the time to make this great content! I've been watching ever since rotary SNP mentioned your channel. I usually watch on my TV so I don't normally get to comment, so I thought to take a min to look you up on my computer and say thank you for taking the time to document and produce these videos.
It's been my pleasure! Thanks for taking a moment to leave a comment. I really appreciate it! Also, I'm not familiar with SMPRotary. I'll have to check him out. Do you recall which video he mentioned me in? I'd like to thank him
Nice work! Keep it up!
Awesome work !!!! Many ways to have perfect way to gol. Can't wait next project. 👌
Thanks!
Great end result, but it's the journey that counts. So many learning experiences. Well done.
Exactly. Thank you!
Beautiful work.
Excellent job.
I discovered your channel a few days ago and I've been binge watching your videos, excellent work, I'm really enjoying watching your projects (including all the side projects!)
I'm glad you like it! Welcome!
I love Your videos!! Incredible quality and narration. I love seeing all the upgrades you made to Your machines in previous videos!
thank you!
Really enjoying the journey...great channel
I just got into 3D printing and am diving into the CNC world. Zero experience with any of it, let alone any machining. I have no clue what's going on in these videos but I absolutely love this channel. Cannot stop watching, and now I wish I could go back in time and study machining. These are great and extremely informative, even for someone who struggles to cut a straight line in wood. I thoroughly appreciate the "side project" counter, and that you include the goof ups.
Glad you like the videos! Thank you so much
Woohoo! Always a pleasure to watch your content!
That was really very deeply deeply satisfying. And a fundamental reminder that the first one always takes 10 hours and once its all dialed in each subsequent one only takes 10 minutes. Beautiful as always Brandon, thank you. Loved the blooper at the end with your partner 🙂
That's exactly right on the timing 😂 Thanks as always, N!
@@InheritanceMachining ♥
Absolutely top notch!
That was worth watching, very nice work indeed!
Thank you!
Awesome. Well done.
The Number One thing I use all my tools for.... is to make more tools. That thing looks beautiful, and the detents are a great addition that I wish more chucks and adapters had.
That's exactly right. Thanks!
very nice another tool finished, for making more tools
Exactly
Gotta love a machining channel like this .. keep up the great work man (y)
Thanks man!
Well done! It was a very complex part to complete, I really enjoyed
Thanks man! I've seen your work so that means a lot coming from you
awesome! id love another upgrade video like you did with the mill for the lathe.
Oh i'm building up a list 😉Thanks!
Amazing work, great video and awesome narration. 👏
Thanks, Anthony!
I’ve binged all of your videos multiple times now. The “ease” and the patience you have to get everything dead on is inspiring. I’m not sure if anyone has mentioned this yet, but doesn’t a rotary broach need a special holder that lets it wobble a little to make the cuts? I’m working towards getting my first lathe and then a mill and I was just wondering if that’s the reason the broach broke. Or are the holders just a way to make it easier? Anyway, your channel inspires me to always do my best work, no matter what. Keep it up!
