Making a MASSIVE Fly Cutter || INHERITANCE MACHINING
Welcome back to the manual machine shop! In this video I’ll be taking on everybody’s favorite cutting tool. The fly cutter But of course I will be putting my own flare on it, by making it MASSIVE. And not only that, it will also be adjustable in diameter and will accept tungsten carbide inserts. The motivation for the project comes from yet another project where I will need to be able to fly cut a plate 9 inches wide. As normal for my projects, the engineering behind all this is done on a good old fashioned drafting board. The build will be made up of several components, made from different materials I already had laying around the shop. An R8 arbor to match my vertical milling machine will be press fit into a large aluminum wheel that makes up the bulk of the cutter. But to make the cutter adjustable, a separate insert holder will mount on the wheel via slots. Some other miscellaneous hardware round at this build. And as many will be pleased to see, I’m actually black oxiding the parts this time! But mostly for looks ;)

Thanks for watching, folks! Tune back in Friday, December 9th for the real motivation behind this project, another project!
There should have been a side project counter 1 at the start of this video 😂
Round and round we go!
Make a model jet engine
If the earth was flat this man would find the edge and put a chamfer on it!
I will be here the 9th.. You sure are a mighty fine Machinist .. Great work man, ENJOYED👍👍
making tools to make tools to make tools... the never ending shop dilema
toolseption
This is the way.
You misspelled "joy" as "dilema" somehow. 😂
You literally wrote down my thoughts word for word. Wanted to write “making tools to make tools to make tools”.
I want to see someone start with literally no tools and build their way into a well-equipped workshop. Need a hammer? Find a rock. Need a better hammer? Find a sturdy piece of wood and grab your rock. Need some metal to get you going? Make a forge and melt some ore/scrap metal. Need a lathe? Cast some big pieces of iron and get to building! Need a compass? Make one. Need a ruler? Okay you got me, you can buy one of those lol
The number of times your ‘gut feeling’ or ‘instinct’ to ensure your machines are true and properly set up have saved so many of your projects is unreal. You’re awesome Brandon!
It pays to over think things 😂 Thanks!
I wonder how many of those gut feelings are a memory of doing something similar, but the wrong way, pop up just in time
The laugh at the culmination of all your efforts! 🤣 you sir, are a champ! Thanks for all your content. It’s aces in my book! Looking forward to December 9th! (P.s. I’m asking for an IM hoodie for Christmas from the wife and kids. 😎)
😂 My Pleasure! From what I've heard, people really like the quality of the hoodies!
The laugh of triumph was, by far, my favourite part. 😂
I had to stop and rewind back, then raised my volume to hear it again! It made me grin too ;-)
That, is a cackle of expectations exceeded !
When you pick up the final piece and the results exceeded your expectations. Love that feeling!
Gotta say man , I watch a lot of KZhead and your channel is easily the best. The way you film every single thing and narrate is top notch . Can't wait for the next one.
Thanks so much! That really means a lot!
Hey, what about Clickspring?
His narrative reminds me of some show or movie while i was young, but I just can't put my finger on it. It really draws you in and makes you want to hear every thing he says.
@FireballTool
Yes the narrative is nice, you also include the machine sounds. That sounds real for a machine channel. Thank You Sir
I absolutely love that the box of shame is a thing, and even as short as this channel has been around, I immediately caught so many throwbacks, it was an amazing nod to the works you've created so far
If the earth was flat this man would find the edge and put a chamfer on it!
Ahahhahahahah😂😂 i love this!!!!
This comment deserves more likes 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
I love the physical drawing planning of your parts. It’s so nice to see that old school technique staying alive.
I use Sketchup (Layout) and often struggle to get my drawings looking this clean and professional. Then again, I'm an idiot with a PC, which is no substitute for someone formally schooled in the subject.
I was going to comment on this also. It took me back to 1965 and Vocational Drafting in High School. Loved the erasing shield shot!
I very roughly hand draw most of my projects in a notebook. Definitely not to scale as I've lost my scale rulers since college, but I put the important measurements where they belong. I just recently bought a 24 inch beam compass at an estate sale for about $5... nobody else knew what it was. My machines are way smaller bench models, but I'm going to make one of these in 3.75 inch for my LMS 3990 mill. My small parts will be pretty tiny compared to yours. Love the videos. Also... if you inherited a machine shop... weren't there machinist jacks just laying around?
Yes agreed; love seeing the draftsman's table and tools. Art to me.
Not only are your projects very impressive, but the amount of them that you keep pumping out is borderline insane. I love it.
It's a lot of work so I really appreciate that. Thank you!
When you inevitably hit 500k subs. The box of shame should get a scrap metal challenge!
I like that! I'll definitely do that if that happens. Remind me!
Not sure why I thought this was a build for a gigantic housefly decimating tool, but here I am
As much as I can respect you drawing all the plans by hand, I certainly do not miss it. I'm so glad CAD and especially 3D CAD is a thing now.
I really wait for your video. Your quality of machining and videos inspire me a lot.
I'm glad to hear that! Thank you
only 8 views, I haven't even seen it yet and can guarantee it's some of the best maker content on KZhead.
"box of shame" I laughed so hard that I couldn't watch the video anymore
That a great tool you made..... Now it will be great can't see you make the rest of shop tools, with your home shop tool you made.
Just a small tipp: be carefull holding the file that way when ur using the lathe. At my workplace we hold it in the opposit hand so ur left ellbow is not over the spindel. My boss showed me pictures of a guy who used to work there and broke his arm because his elbow caught the spindel. Love watching ur videos. I already learned a great bunch from u. Keep up the good work. Greetings from germany
I just want to second this. A lot of the old timers will teach this way of filing and it makes absolutely no sense. It needs to be phased out and forgotten.
Thats a fair point. Learned that from my grandfather and while it does feel more stable there's definitely higher risk of getting wrapped up in the machine someway. Thanks for the support!
What part of the video was that?
@@Sky-._ 10:50
@@WoLpH thanks!
The side projects counter is one of my favorite parts of you videos. Great fun watching you learn.thanks for taking us along 👍.
My pleasure. Thank you!
Cannot tell you how much joy it brings me to see such impressive drafting skill still around. It’s a dying art and one I love so much so it makes me happy you carry on the tradition and craft
When I was a wee lad, I was told of the superiority of down milling. "What an idea," I exclaimed with visions of recutting in me mind's eye. So with me roughing strategy converted, I made a plan for the next visit to the knee mill. Into the vise goes the block, with a 1" endmill into the spindle. Touching off the part, I drop the endmill down to full depth and give the handle two cranks for a nice health .2" cut width. I engaged, noticing how light the handle turns, then bam! The mill self-feeds until destruction.
New mark rober video just came out, but I'm totally watching this one first!!!
😮 Wow... thank you!
Tool making is one of my favorite sub genres of machining. It's always so interesting watching how the machinist works around challenges, like drilling the holes around the spindle. Great video Brandon, hope you had a great Thanksgiving.
I definitely like solving all the little puzzles that come with each of the projects. Thanks and Happy Thanksgiving to you and yours too!
That laugh at the end was so rewarding to hear! Amazing work!
I loved that maniacal laughter, I do it myself occasionally when something works out perfectly... :D
Funny thing is I rarely make much noise in the shop... other than cursing like a sailor when something goes wrong haha
The quality of these videos blows me away every time. It's amazing to see someone who is so passionate and creative doing the things they love at such a high level. Hats off.
That is very kind. Thank you!
Alternate title "Making a massive side project"
As a kid from the drawing office (in heavy civil) it's nice to see a drawing board in use again.
upon seeing the thumbnail and title i instinctively understood for the first time the purpose of a flycutter’s design. you’re a wizard
Great work, Brandon! The final result was fantastic! I absolutely LOVE seeing that type of machining tool marks on a flat surface - like a freshly milled cylinder head or engine block. I'm very excited to see what you do with this in future videos. I hope you and your family had a happy Thanksgiving! Keep up the great work!
Thanks Jay! Happy Thanksgiving to you and yours as well!
Wow, the surface finish on the very first part was just spectacular! Very impressive!
We built almost exactly the same flycutter back in the early 90's. Our shop made 100% aluminum injection molds for medium production jobs. Over the years literally thousands of mold plates were flattened and the flycutter machine marks were an unexpected source of cavity venting. Any errors in the machines quill bearings are grossly magnified in the resultant surface finish and I would modify the cutters leading and trailing edges to minimize chatter and wiping. It was a shared tool by all of the guys in the shop and I was the only guy who kept custom inserts. But. On an early morning start I installed the flycutter on the mill and started the spindle to warm up the bearings. Got a coffee and came back and started to run the HyVo speed sheaves through their range. At a high RPM one of the insert holders turned loose , shot out of the flycutter body on a trajectory that took it between my friend Gary's chest and his vise, across the shop barely missing the lathe headstock, , impacted my engineering bench sending papers flying up and everywhere , deflected up and through the roof. Please... never run these types of tooling at anything over 1kRPM's. And always check that the tool has not been left in an unsafe condition by the previous user. I used a pair of r/h cutting lathe tool holders. Careful setting of the 2 tools to 0/0 on depth and swing diameter really helps function, and balancing is also important, but only has to be done once. Hearing that slight ring of the cutter in this video really brings back memories for me.
I love this video but I'm with Tooly on this one. I'm about as far from a safety nanny as you can get but there is a reason you don't see these kind of huge high mass fly cutters very often. It's not if, but WHEN like Tooly said the insert or insert holder gets smashed off and launched or just as bad if this thing catches and throws a part out of your vise the projectile will be able to go through people and walls. Lethal. The minimum you need to use something like this is a full enclosure with solid enough steel to trap a thrown part or tool. I get nervous running my little fly cutter at the 3-4" settings. If it tosses a part or the cutting bar comes off it's going to be a missile. Far better to get a big cheap shell mill head and just run 1 or 2 inserts in it. You still have to protect anyone in the shop from a thrown part... but it's far far far less likely the the tool itself will grenade completely in a crash.
"Alright, let's take this bad boy for a spin." You are/will be a good father.
Watching you design and draft by hand using pencil and paper fills me with joy. Technical drawing, taught to me at school in the 1970’s was so enjoyable. Brilliant episode. 👏👏👍😀
Thanks!
You know, you can use a toolpost grinder to grind the arbor while it's in the mill spindle. Since R8 collets only go in one orientation, it would ensure it stays very concentric. Also that saw blade looked to be standard carbon steel rather than bimetal. Carbon steel blades get wrecked in short order by tool steels, especially ones with manganese and molybdenum like S series. Companies like Lenox make blades specifically for cutting tool steels that work quite well.
It's a pure pleasure watching pieces of metal turned, cut and machined into a useful object. I find the whole process really calming and relaxing to watch ! Found your Ch recently and been really enjoying seeing you use the machines your grandad John left you and being used so well. I guess he be smiling down on you, when hearing the pleasure you get every time you laugh or smile at a piece of work your happy with !! Great Ch great content !!
Really appreciate you showing your failed pieces. There's a lot to be learned from how things don't work, just as much as from how things do work.
Loved that genuine smile at the end lol. Love your vids!
So did I! I'm sure he had to practice it a lot to get it right!
😀 Thanks!
That's a really cool, and also frighteningly huge, fly cutter! Loved the laugh at the end, would probably feel the same 👍😁
Not going to lie I was slightly on edge the first time spinning it up. 😁
When I first saw that massive disk of aluminum, the smile on my face had the biggest grinchy smile. But that would be absolutely rid-donk-ulous.
I love the fact you draw things by hand. Your work looks amazing!
Your channel is easily up there with the best KZhead machinists, each with their own different approach and skills, very well done on your machining talent and your production skill too, thanks for your efforts and content
I really appreciate that. Thank you so much 🙏
This was a really fun project (with lots of side projects) to watch. It came out very nicely as well. I laughed at the finished product spinning up just before you did! You may have a “Box of Shame” to hide your failures, but I hang mine on a “Wall of Shame” to haunt me into being better
😂 Thanks! I might have to do that for some of the bigger whoops. I can think of one already!
I love this channel. The amount of times I sat down to watch an half hour video is unreal. Keep doing your thing, we love to see it
The suspense and the unadulterated joy caught live after the test... That's why I'm a fan :)
I have no interest in machining but... man are your videos entertaining ! And the end result is so pretty, it's magical to see the metal just disappears, well done !
That actually means a lot. Thank you!
I second this... I've got 2 left hands, no skill at all... ... but I love these videos, because they show the skill you have and pleasure you get from applying that skill to a task
Nice work! You could make this your daily business... It would destroy your hobby though so be carefull (victim talking here). I made quite a few fly-cutters and, as you mentioned, mass is important so my last versions where made out of steel with a 25 mm shaft for easy exchangeability between my machines in a collet. Runout is no issue on a fly cutter just like a boring bar with only one point of contact with the part to be machined. I learned, next to mass helping the finish on the part, that it's easy to get a great appearance for your part but that it's not so easy to get tight tolerances using the fly cutter. I'll explain; if your mill is in good condition and the vertical head is trammed in true the appearance of your cut should be a cross pattern meaning that the flight of the cutter is perpendicular with the travel of the axis your using. This cross pattern means you'll end up with a flat piece after using your fly cutter. At first; this is not so easy as it sounds, especially when using large fly cutters. Then there's the next dilemma; a cross pattern doesn't look good at all but serves accuracy as you would like also. An older machine will have some sag in the direction you're cutting and this will show unforgivably in the tool marks on your part (some cross pattern, some shiny area's). If the part doesn't show a cross pattern this means the head is not trimmed right in the axis you are feeding. "Bling" result but also concave when it matters. In short; when it needs to be accurately flat I choose another method; traversing with an endmill with 50 to 75 % overlay between each path. Cosmetically this leaves a not so nice finish but when measured it wins from the fly cutter. Because of this "feature" I only use the fly-cutter to obtain a nice shiny surface. If I'm trammed in by accident (🙂) I just knock the vertical head slightly out of alignment to get the desired mirror result. Just my two cents on the fly cutter topic. Maybe it helps to determine it's use on a particular job. Thank you for sharing another wonderful episode in your journey in a magical place. If I would work in my seized granddad's place I would be a painter and I'm not. But I still own a few items he used and they're priceless to me. I miss him terribly and I guess you are too. Thank you! All the best, Job
Thank you as always, Job. Those are some interesting points on the accuracy of the final surface. I've often heard that if you get cross hatching then your mill is off square, but that never made sense. Your explanation does. It would be an interesting experiment to blue the surface plate and see how flat the plate actually came out.
I gor bit by this bug in highschool. But i mever learned enough to do proper machining. I wish i had all your knowledge. And the fact your grandpa taught you it all is AWESOME. Im subbed and binge watching all your stuff. Its really really amazing. Good work
This is without a doubt the best machining channel on the internet! Thank you for taking the time to narrate things. It greeting helps those of us new to the hobby!
I didn't see any flies get cut. I am disappointed
Loved seeing the old school drafting machine and paper. Brings back memories from WAY back when. Always seem to THINK better with paper and pencil. Never grew to like CAD on computer screen.
This two week gap between videos doesent work :O I want more videos, I just love watching videos like this. Keep up the good work!
haha If I could make them any faster I promise I would! Thanks
Loved the drafting machine in use and the box of shame. I hang mine on the wall behind the lathe in hopes of finding a purpose for them. Been saving nearly 50 years now and still haven’t used but a couple. Also liked that the cutter turns clockwise. Don’t know how many times I’ve seen an experienced machinist make a fly cutter head backwards. 😊
Great work on this fly cutter design and making, love the tips for squaring up the 4jaw to the lathe
That surface finish! Wow
Greetings from the UK. I absolutely loved watching you craft this tool. Your workshop makes me jealous! Keep up this great content please.
Yes! Found your channel like 3 weeks ago or so and am currently at my second round of watching all your videos, when this drops.
Wow! haha thanks so much for the support!
That laugh of joy after your test was delightful, made me laugh too
How nice to see using classic drawing tools. Magic
Awesome job. Very good engineering and machining. I think everyone could use one of these. Thanks for sharing. Take care, Ed.
As a woodworker who has done VERY little metal machining, I have learned a ton from your channel, and find it fascinating...though I doubt I would ever pickup machining metal. Nevetheless, your work (from hand drafting to the tools and jigs you've created) is both admirable and just plain cool.
wow granddad put together a really nice set of tools, thanks for this project!
I appreciate that you show and discuss the planning process. A good machinist is as much an engineer as the engineer is.
So one big side project, lovely finishing cut as well.
The box of shame had me laughing, a little box of memories of what not to do. Brilliant video.
i love your videos! keep up the great work, your videos have the perfect balance between entertainment, satisfying cutting shots and explaining your thought process
Thank you! I really appreciate that
I don't watch many videos start to end but your work is great. You remind me of 'This Old Tony' and I wish I had a grandfather leave me all those tools. Getting the nice machines you have is one thing but collecting all the parts to use with them takes time.
Dude that's FREAKING AWESOME!
Love your channel! I really love your attention to detail and appreciation for excellence. Thank you for sharing your shop with us
My pleasure! Thank you!
With every video I grow more envious of the tools you make...
This just makes my skin tickle knowing how far we came, both as a community and as people. Also make tools to make tools to further make more tools. A game of web catching.
I learn a lot from your videos! Please keep it up! You have sparked my interest to become a machinist and I can’t thank you enough!
That's awesome! It's been my pleasure! Thank you as well
23:23 the definition of first chips and a job well done
This is the first video of yours I've seen. I absolutely love that you use a drafting machine, triangles and templates instead of CAD.
It's so awesome that the previous projects keep coming back in to help you out when you need it the most!
Not all of them were worthwhile, but some of them I couldn't live without at this point!
That enjoyment when you had the cut plate in your hands was delightful! Congratula!
There's something about watching a quality engineer at work hence why I've subscribed 👍
Respect++ for you drawing. Very neat and clear
the "box of shame" 😆 I love it. I keep the first rounded oil sump nut I made right at eyeline in my garage as a reminder not to believe in myself too much.
Me bored, me open youtube, me get bored, me open your channel, me not bored. Well its true, I've been watching this video for 3 time already, I am still not getting bored with your content. Love it!❤ Easy to understand❤
Wow! A beautiful project and a spin on the classic flycutter that i have never seen before! Thank you for sharing your amazing creativity and some wonderful insight as always
Much appreciated! Thank you as always, Charl!
Love your shop.
the result and the laugh was golden.
Extra large fly cutter coming up!!! Nice job
Watching your work is supremely enjoyable! Thank you for sharing your projects with the world.
My pleasure! Thank you for watching
love that near mirror finish on that test piece.
A delight to watch, nothing better than a calm voicover and impeccable machining
Thank you 🙏
Both relaxing and satisfying to watch. Keep it up!
Fantastic result! I love toolmaking
500k views 200k subs. Inarguably the most underrated and slept on machining channel on KZhead.
Hear, hear!
Beautifully done. Love watching a good toolmaker show off. Looking forward to more!
Thanks!
Watched all your videos today and I am totaly flashed! Great work! Congratulations! Viele Grüße aus Hessen, Germany
Awesome build! Off camera laughter was hilarious too...😂
Awesome to see your process
Absolutely love all your videos. Also I love that you take the time to properly subtitle everything. It makes it easier to watch and understand.
I appreciate that!
Excellent work.
Just can’t get enough of this channel!!!
I consider this channel as some sort of therapy. Love it.
23:21 Mad scientist moment! 😅 Mad props! 👌🏻
Beautifully presented and the Box of Shame is a classic. We've all got one of those! I very much enjoyed listening to your narrative and seeing the metal form before my very eyes. Thank you for an entertaining and instructive video.
My pleasure! Funny how many people mention hanging onto their mistakes! haha There is a lesson in each one!
Impressive is all I can say. ...Plus >... I'm just a little jealous of your skills !!!
