- If you want to build your own Cyloidal drive, let www.pcbway.com take care of the machining.
This was one heck of a project, but I made it in the end. A (nearly) zero-backlash 4th axis for my home made milling machine.
If you want to follow the projects a little closer, head over to / notanengineer .

I think I'm gonna need a bigger box
This was such an awesome gag to see. Reminds me of This Old Tony and Clickspring. One day i will start a channel in my own shop and hopefully get big enough to do a collaboration with IM.
You will need bigger box, but he will need "crate of shame"
The first time watching "not an engineer" made me subscribe to InheritanceMachining😂😂. Waiting for your video of this new element added to the box of shame.
could be a fun side project building one tho
Definitely got my click 😂!
This man ACTUALLY sent his first design to Inheritance Machining just for a 20-second gag.
The most expensive bit so far. Worth it.
Shows commitment. Respect.
@@NoEngineerHerewell it gained you a view and a new subscriber (me) that wouldn't have seen you if it weren't for that small bit lol
@@kshepthedrummer+1
Worth it!
As a swiss cnc machinist some of this kills my soul but you are very talented and intelligent.
It must be the Swiss in me. Working on getting that passport so I can come and see how it's really done.
The PCBWay ad was legitimately useful. I absolutely did not know they do machined parts.
The Inheritance Machining cameo was everything i never knew i needed ❤
fr
When I was watching the intro I was thinking "did I see Inheritance Machines box of shame or what the hell did I see?". Glad to be right. Lol'd when his cameo began.
Two my heroes in one video!
@@MadcapPanic 15min mark roughly
That was awesome
The irony of a PcbWay ad including a complaint of a local machine shop going out of business is hilarious.
To be fair no amount of patronage saves these places going out of business because of landlord greed. Meat markets and machine shops are insanely profitable, which is why landlords target them so hard. This creates a positive feedback loop with regard to average rent.
@@AndrossUT In this particular case, the owners passed away and the children inherited the property. With all the gentrification going on around here, they tripled the rent and instead of a machine shop we'll have a pet barn.
@@NoEngineerHere thanks I hate it
@@AndrossUT Landlords aren't charities, they also don't target anything. There is the value of the land and if the other guys are willing to pay more why should the landlord settle for less. I'd like to see you refuse a pay raise before you start asking others to do the same.
@@DmitriyLaktyushkin landlords are leaches. They should get real jobs
There is another type of cycloidal reduction box you can make that is easier to get backlash-free & easier to fabricate because all the critical machining is groove into planer disk surface. The engagement is axial, not radial. The "rollers" are ball bearings acting between 2 grooved disks. Because of the axial arrangement, backlash can be taken up to compensate for wear or fabrication. 2 facing disks have cycloidal track machined into them: one hypocycloidal, the other epicycloidal. Ball bearings roll between them, held under axial compression. 2 stacked assemblies are used to remove the orbital motion & the difference between the 2 ratios permits large ratios with low lobe counts. A central crank forces orbital motion (same as for drive you have).
This was my first of your videos. This was hilarious. The soldering iron microphone, the dryest humor. Love it
Gday mate sound engineer here. If you use the bigger desk based soldering irons with the spring holder you’ll get a much cleaner vocal recording.
"Gday"?
Another wank boy too tired to write?
I just use a modified crackhead lighter and a ice pick no wonder my audio is so bad
I think that's a modified earthworks M50, isn't it? I would think that's pretty clean, but agree that it might be a bit sterile-sounding. Maybe the mod will allow for some added low-end warmth.
Hot mic!
Does that one use 120V or 220V phantom power?
23:05 Classic blunder! Never wear open toed shoes in a machine shop. They trap swarf like nobody's business. Always do your machining barefoot!
Print toe caps for your chanclas. Worked for me.
barefoot is a bit too much protection for my tastes, I like my wang out and about near the spindle, lead screws, and thread feed when machining, which of course disallows the use of pants.
Nude under a leather apron like "I did a thing" is the only way for an Aussie to do machining/fabrication imo
(That one shot where he is dancing, barefoot and nude except for a leather apron, *on top of his lathe,* nearly gives me a heart attack)
According to some Bangladeshi casting and machining videos I’ve seen, Safety Sandals are absolutely the best way to go while working with hot and sharp pieces of metal.
i put my feet in a subway footlong
These projects are so impressive - absolutely love that the IM box of shame got used
Once I've got the 4th and 5th axis set up, I'd consider taking orders for rocket components 😉
@@NoEngineerHere I'm here for it! May your skies be blue, and your swarf never land between your toes.
Welp, now there are three cool channels that have made an appearance in this video, although I shouldn’t be surprised to see BPSspace watching this channel.
FINALLY SOMEONE WHO SPEAKS IN HUNDREDTHS OF A MILLIMETER INSTEAD OF MILLIONTHS OF A FOOTBALL FIELD
Also at 22:10 dude knew exactly what he was saying I don't believe in his innocence.
Millimeters are way easier the thousand on a crapy inch....
@yanikivanov Why? They are just as precise as each other. It makes sense he uses metric because he is Australian if he was American or Liberian or even British then why wouldn't you use the measurement system that makes the most sense to you?
@@phinox6052because fractions are fucking stupid when you are trying to be precise.
Weirdly starting to believe youre in fact an engineer....
I wish people would stop with these rumours.
lolz😂
Did you just assume his degree?
@@NoEngineerHere You could always start saying "I'm an enginear-enough." :grin: (T-shirt/mug/etc. merch drop, perhaps?)
@@KeithOlson difference between a scientist and an engineer is that good enough is enough for an engineer.
great to see the box of shame has international parts now 😂
I came for some fantastic content. And then i came back to rewatch it again to find the details and easter eggs.
The editing and attention to details are such a massive step forward. Well done!
Wow. What a project. Thanks for seeing it through
I felt the first mention of "side project" as a foreshadowing. I'm glad I wasn't disappointed. I can't believe the box of shame has something with a complete lack of chamfers.
Made me think that one of them inspired the other, but being this is my first video from this channel, I can't figure it out yet.
@@NOLAfugee IM has been going a bit over 2 years, and NTE is about 8 months old.
I felt that one too. I was wondering. That was amazing!
I love how, when you started this project you were like "I'm not confident this thing can cut a circle." and then at 18:24 you evolved to "f@&k it, if it can cut one circle, it can cut *TWO* circles"
That is the CNC machining way just send it
@InheritanceMachining sent me here and I'm glad I found you! you're work amazing and im laughing along the way. extremely enjoyable and a pleasure to watch. look forward to watching future videos!
awesome project. Its so much appreciated that you went all the way!
I get it now. This channel is you building tools so you can build more tools. The tools aren't going to be doing anything more than upgrading themselves.
Can't wait for this guy to kick off the singularity in his garage machine shop in an effort to create tools to make better tools
Bootstrapping!
the Patreon plug in the overlaid subtitles during the [hispanic?] BGM was kinda spicy
I liked it
💃
I've rebuilt a few of those cyclo drives at an old electric motor shop I worked at years ago. Love the video. a laugh around every cut scene.
You put together a really good video in the way you present yourself. I admire anyone with a vision for ingenuity and thinking outside of the box! Great job!
That Inheritance Machining bit got me, what a colab.
That soldering mic might put your eye out, mate.
Only if you look at it funny
I get the impression he doesn''t give two flux... 🙄😂
😎👍☘️🍺
Incredible machining, and incredible animations! This was really entertaining story telling, combined with some nicely timed humor. I can't wait for more!
That was really really interesting. It makes sense of the various references I've heard to genetics in the past several years. Thank you for the explanation.
Also I don't think it's boring at all. The fact that the works is more nuanced and subtle than before just gives us more to discover and use imho
Holding a soldering iron like a microphone alone was already worth the like. Truly a masterclass on what a CZcams video should be.
That's what drew my like and subscribe lol
has he somehow accidentally poke his soldering iron into his nose while talking?
Should be an old fashion pipe.
It's like watching an Australian version of This Old Tony
Machinist Theatre at a high level.🤩
Bit too much of him in frame though, maybe he could learn to do things with only his feet
Yeah nah, we saw his face.
… aaand, I didn’t hear him say “Skookum” a single time..
Iss all Tiny
This is more than a little bit awesome. Looking forward to seeing what comes next 👍 🇬🇧
Arrived here from IM and have just hoovered up every minute of content you've so far put out. I've not done that amount of back-to-back CZcams onsessive watching within the same day since I discovered Bobby Fingers. You're killing it - and making me realise that I need to embrace the Dunning-Kruger effect a little more in my own workshop. Nice one.
Charlotte
For future iterations: such high precision circular patterns should be made by indexing the workpiece with dividing head while keeping mill XY locked. Mill will always have some backlash and XY mismatch as well as XY perpendicularity error.
All of these together will create hot mess when absolute position and circularity are important.
I had the same thoughts - thats the real reason I mounted everything on the rotary table at the start. But then I thought - screw it, lets see how it goes.
@@NoEngineerHere also as you said in the video that coupler is flexing a lot and a stiff one I belive will drastically improve the flex. It is designed to flex to reduce stress from jerking movements but thats of course exactly what you dont need.
That’s got to be the best pcb way ad ever
Jlcpcb tends to be cheaper… lol
great video man, very well put together! i'm hoping we'll see more of this gearbox in the future
Oh boy, your videos are absolutely fantastic. The music, the tone, the subjects. I wish you the absolute best. Thank you very much.
When I saw the bit about the box of shame, the parts being packed up and DHL I just about twigged before IM strolled into view. Definitely the right home for those parts. H'mm that gives me an idea ... I had parts jumping out the lathe spindle this weekend that I'm ashamed of ....
IM might need a bigger box if all of us send him our failed pieces.
@@schwuzi 😄
@@schwuzi I kinda like that guy, I'm not sending him my Ex.
Cue the IM subsidiary "Recycled Shame". Motto "Ship your shame to the other side of the planet, where something good might come of it. When the bin's full."
17:40. Good thing you had Leeloo to help you lift that new bandsaw.
Multi pass
Plays halp
Chicken good.
I have no idea what its use is, but it is beautiful and I really enjoyed watching you make this beautiful thing!❤ looking forward to learning what it does in the future totally here for it!!
My friend - the little gems throughout your videos are fantastic. Truly a joy to watch.
That side project / ad read was class
Very glad to hear 🙏
Oh man, sending it to Inheritance Machining's box of shame was genius! Subscribed.
when someone has complete proficiency at both machining and commercial video writing & editing...the public wins.
It's so satisfying seeing you redo the same work over and over again so calmly and eventually get the right results.
As an engineer, I absolutely loved your time-warp effect ❤❤
...and also your creative use of translated lyrics subtitles between 18:00 and 20:00 was just genius! First casually building confidence, then sneaking in the message 😂😂
Thank you for an absolutely wonderful video!
The quality if your videos and everything you put out on your channel is legitimately insane. That doesn't even take into account the size and age of your channel, if you do take that into account, you're on a whole different level.
Thank you for making awesome content, you rock!
Fabulous video, thanks for sharing. The end result was stunning. The Inheritance Machining gag was great. At 23:00 I really like the steel toe protectors that actually conform to the shape of your toes. Mine are the old fashioned one-piece kind.
I just watched inheritance machine and then came to him. The two are perfect for each other. I’ll now watch both.
Thats an impressive build 🥸😃
Mate the standard of your work for someone claiming to not be an engineer is nuts. You create some of the most precise things I've seen on CZcams from any channel that's not a company or Clickspring, another Aussie, (is it something you drink?) but the 2 of you work at virtually opposite sides of the scale. The Inheritance Machining gag was top notch another thing your channel brings to the machinist space, a bit of fun not taking something, you obviously do very seriously, to seriously something until now I had to rely on This old Tony for. Thank you
It’s gotta be the Vegemite…
@@Turnipstalk so you don't watch inheritance Machining then? The bloke who runs that is exactly that an engineer who does top notch machinists work on his channel. Which a part of why the joke in this video. Oh and not sure why you felt the need to tell me this when my "for someone who claims to not be a engineer" is just a saying nothing more. I don't expect him to be both nor does it matter to the quality of his work.
@@Turnipstalk sorry bro having a bad day at the time and reacted without really taking in your comment. Get so used to getting attacked on CZcams by people being, well people who can say what they want without consequences that it was basically automatic.
So much knowledge that it takes to get to the point where you can even begin this project. Amazing!
I was already enjoying this video... and then the cameo really got me smiling!
I hope this is a glimpse into a possible future collaboration project!!!
24:10 That is called an internal nut.
Also, in some instances, it is called a 'gland' or 'gland nut' [mainly in hydraulic applications and maritime drive shaft applications, where some form of [usually lubricated] fluid seal and sliding, or rotating shaft is being held by the assembly.
Hm I thought an internal nut was something else entirely . . .
] 😅
A not-engineer sends the culmination of countless hours of work to an engineer. Engineer promptly stuffs said project into a box of shame.
Despite the forewarning of the lathe crash, I still got a jolt of adrenaline when it hit.
Love your work 👍
17:49 i appreciate your effort with including your lawn mower and LONG grass.
Easily missed by your average punter but a true Easter egg😊
Love your futuristic mic bro, glad you made it!
That lathe clip in the intro
It lives rent free in my head
@@NoEngineerHereI am a Machinist, and I accidentally selected a feed lever the wrong way once it was .6mm/rev where I wanted .3mm/rev it was going at 400rpm and the 50kg chunk of metal was on a bit of a angle and stalled the lathe instantly I thinking just how bad might of been if it was not a small part in a small lathe
ahh yess the casual cameo of one of my favorite machinists is top tier, also that lathe crash made my soul jump
Thanks for the video mate. Very entertaining. Good luck with with your future projects 😊
i have never encountered this young man before. YT just suggested his channel. wow! this is so up my street im surprised we dont meet when the postie arrives. cheers
As an engineer and a fellow countryman an hour up the F3, it’s so nice to hear the technical term ‘rooted’ in use on CZcams.
I don't have the money nor the intelligence to do the things you do. I've turned wrenches on and off for 25 years. I enjoy discovering how things work even if I don't completely understand the details. I get literally giddy with excitement when you release a new video. Keep them coming! ❤
Weird, I've never found the on/off switch on my wrenches . . . . :-)
I love your engaging video production skills! It's funny and full of easy-to-miss Easter eggs. You're definitely a brilliant nerd!
Impressed by the sound quality of that soldering iron.
I hope the trend of makers sending Inheritance their scrapped parts catches on
Dude you're getting into the realms of farmcraft101, TOT, old AvE and so on in my book. I get excited like a kid when you upload. Good jerb
If your audio was bad, I wouldn't be watching. You've learned the important lesson of having good audio. Bravo.
The script and editing of this video is really good! Keep it up, subscribed!
Watching these videos is just such a joy. Just my kind of humor!
Also I keep tripping over the fact that this is your 7th video, cause they are as polished and well done as if you were into at least the 100s. Just amazing, and thanks for the entertainment!
The soldering iron "mic" is a nice touch.
I was subconsciously waiting for him to suck on it like a hookah
good to see the full process , nice one
I found your channel through this video. You are effing awesome. Love your work, attitude, and your videos! I've watch all your videos in the last day! Can't wait to see more!
It's even funnier when you realise he is holding a soldering iron which actually has no mic attached 😂. Love your content!
Man you really outdid yourself on this one! The cameo, your wife/girlfriend/whatever shouting wtf, the project, loved it! Became a patreon after having laughed for a few video's, worth it. :)
I'd love to see full plans for your design! I designed a similar (but much more compact) gearbox for robotics use and ran into similar constrainment issues.
man that was so cool to watch i love seeing an idea come together. for a prototype id say that was very well done. someone give this man a larger budget.
This is a final test, a true engineer would never ever think of doing a cycloidal reduction himself. Never, no chance.
You never fail to disappoint my upside down friend!
So close to 100k!
Love the fushia pop of color on your lathe!!!
Congrats to 100k
Has anyone realized how mind blowing & amazing it is to have Nearly 100k subscribers AND ONLY 7 VIDEOS!
I think you are doing something right, looking forward to more content.
What I need from a gearbox is some more alcohol. Love your vids 😊
The effort and the cost just to send the parts to the Box of Shame (on the other side of the planet) is truly the sign of a great channel, and a great content creator. Subscribed.
"it really came down to rushing the design, and leaving the problems to 'future me', and now I'm 'future me', and it's a problem"
So, I'm watching this man make a very complicated gearbox to remove backlash. But so far he hasn't mentioned why he NEEDS no backlash whatsoever. What application needs this design?
I can't think of one offhand for something at home, but I've run into them at work for speed compensation gearboxes in printing where any backlash results in huge changes in print or cut quality
For some axis movement on his CNC machine. Any backlash will take your milling tool out of center
Awesome engineering for someone who's ..... not an engineer! Though I was a little confused when you had PCB way machine the simple stuff, and you tackled the complicated high precision work in your shed. ??? By the way, what was the cost comparison of the PCB Way insert tool holders to the import sets? I've seen many CZcamsr's make tool holders but I have found that the import holders I have purchased are of extremely good quality, and I couldn't even buy the materials and hardware to make them myself for the cost of an import sets, let alone the incredible amount of work to make them.
Great video as always! Regards.
Those holders worked out to about $70usd a piece, with shipping and customs, not including hardware. Of course that price comes way down if you're just getting bulk of one style. If I'd just gone with like 20 of the extended style, I think they'd be closer to $50USD. Worth playing around with their quoting system!
Mind you the import sets are a bargain, and totally fit for purpose. I just wanted a couple of special features. The extended holders make it much easier to use a live centre, and as far as I could see, there aren't any cheap alternatives the the $309usd aloris model
@@NoEngineerHereThanks. Yes, they are a bargain. The last 5 piece set of BXA holders came in at less than $14 usd each with all of the hardware, and were very nicely surface ground.
Made me cry thinking about that one day I really thought I could mill one myself, rather than printing it!! Thanks for showing all the effort!! Congrats on the build!!
Well shot, well edited, funny end scenes. I'd love to see how you make a harmonic strain-wave gearbox.
I'll just make helical gears if I need no backlash.
I beleive it is in fact a "but"
Immediate subscription. Excellent camera angles, personality and pacing.
My favorite aspect of the video is how threatening you manage to look holding casually waving that soldering iron back and forth from a seated position; big Wilford Brimley energy
I'm not a machining nerd but I was totally blown away that you could make such a thing in your shed at home. Amazing!
Excellent work. You demonstrate the second rule of engineering: Patience, Perseverance and Persistence, as in, "Never, never, never give up." Which relates to Thomas Edison's statement "So many people have been so close to success, but not realizing it became frustrated and gave up."
Everyone gets into a deep project and hits the proverbial wall, exclaiming "What the %$^# was I thinking?!" You're a better engineer than many I have worked with, simply because you have the right attitude. Keep up the good work, it is inspirational to the rest of us. And always remember the third law of engineering: "All the easy problems have already been solved by others, and the ones left are close to impossible!" -cheers
Definitely subscribe!!!Inheritance brought me here and I can't thank enough for this! Now I'm going to check and see all the videos!!! I just love machining!!!!❤❤❤❤
Oh! And just love the fact you are using metric!! With imperial i have to pause when it comes to hundres or thousands and do the conversion so i can actually understand the stc and fine adjustments 🫨
mixing in the rhythmic noise with the perfectly fitting soundtrack is genius.
No idea what you’re doing, but the deadpan humour you’re delivering with it is keeping me watching. Love it!
i have never really touched machines. butt i love machine shop videos. this one was one of the best I've seen. can't wait to watch your other content, and see what u do with this cycle thingy
Amazing project, and excellent music choice!
Between the IM colab and the general tone of the narration, this has become one of my favorite channels. Well on its way to elite status. Pretty soon TOT and Ca Lem will be making appearances. This was a great video!
