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.
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.
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.
Not everyone who graduates with an engineering degree SHOULD be considered an engineer. You know more than most about machining, and machine design as well. Really enjoyed your video.
This is absolutely true. I knew an engineer where I worked. I didn't realise how smart he wasn't until he went home one night and didn't realise that he had got on the wrong train. When he suddenly realised, instead of going to the next station, getting off and catching a train back to the starting point and then getting on the right train.... he decided to force the doors open and step out onto the platform as the train was gaining speed. His legs were not working at a pace commensurate with the train speed and when his feet came into contact with the platform he cartwheeled and broke his shoulder. He may have gained an engineering degree but he was devoid of any common sense. No joke, this is a true story.

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.
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.
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.
@@benjaminh5886 yeah, i dont want to know what tomfoolery they pull off to be able to make parts like this shipped across half the world for that amount of money. i live after the motto that the more something gets sponsored on youtube, no matter how good, the further i stay away from it.

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.
@@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.
Back when I decided to prove to myself that I still knew how to do CAD, I designed and 3d printed a cycloidal drive. I also designed and 3d printed a harmonic drive some months later. Good times.
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 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"
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 fun to watch. As a 1st yr elec apprentice with a supply authority we all spent 3 months in the engineering workshop, which I enjoyed, I loved to learn.

To get you back you back for your boring bit crack. I watch a documentary last night on TV. It was about how the hulls of Super tankers are put together. It was riveting!
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 ....

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.

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
@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 TH-cam by people being, well people who can say what they want without consequences that it was basically automatic.
Man, I love your dry humor. Most will not get it unless they have ran into similar issues with projects. My muse is more along the lines of experimental electronic component builds(for example working on an experimental TEG that is entirely printable, it's very touchy. Junction points as small as 1 mil (mil as the measurement mil and not millimeters. Average human hair is 1 mil.) and up to 5 mil. Graphite, graphene, and conductive inks ranging from nickel to gold. Sensitive enough to use sun light to generate. I currently have to draw them out by hand for test models until I get the measurements within a working tolerance. Tedious does not even begin to describe it.), so even though I do not know many of the ins and outs of machining I certainly feel your pain. Keep it up, you are making great progress! Looking forward to further videos like this. You earned a subscriber.
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! ❤
As one who is a DE and uses CATIA, I think it's wonderful how you brought your ideas to life. You appear to be very resourceful and creative. The underscoring lesson here is to appreciate the importance of GD&T in your designs.
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).
@@Nedw Web search gets nothing (I tried "AXIAL cycloidal gearbox). The search latches on "cycloidal" & ignores "axial". I found about this in old optical catalog (for fine motion of optics without backlash). The benefit of this scheme is the ease of making if you have manual lathe & CNC milling machine. All of the "non-circular" elements are machined on a plane surface (simple cycloidal groove that ball bearings roll in). Calculating the CNC files is simple. It is the superposition of 2 circular motions: one is once around, & the other is multiple times around. One plate has path where the 2 rotations are the same direction (makes cycloid) & the other opposite rotations (makes hypocycloid). The (larger) radius of the once-around rotation & the (smaller) radius of the multiple-times around rotations are the same on the 2 mating surfaces. You need 3 plates (2 surfece-sets) total. The center plate is forced to orbit by eccentric. The ratio between plate 1 & plate 2 is different than that between 2 & 3 & in the opposite direction. For example, if ratio 1 is 15:1 & ratio 2 is 16:1 (reversed), the total ratio of 240:1. I do have CAD files of one I made experimentally. If you have place where I can send them, I offer them for you to look at.
I found a patent for an "axial cycloid reducer", then hit a dead end. I also came across magnetic cycloidal reducers, which are neat but have radial "engagement" not axial.
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.
@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?
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 👍
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. :)
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 TH-cam 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
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.
It is really, really hard to stop myself watching this video. I needed a break at 10:00 and struggled to avert the gaze until 24:00. I have finally done it and can make a cup of tea. What a content.
Speaking engineer to engineer: A cyclodal drive is not backlash free by definition, it relies on the accuracy of your production tolerances. In theory, the way the cyclodal drive works, you have a lot of points of contact at any given moment. Take in consideration production tolerances and the concept is heavily overdefined. This can only be made to work by having either compliance or a combination of certain production tolerances and a matching amount of clearance (play, thus backlash). This said, a cyclodal drive is a very interesting gear mechanism, offering very high reduction for the volume it consumes. The inherent low backlash is presumably due to having a high number of tolerance fields overlapping with their respective position errors, effectively lowering your effective clearance. Anyway, great engineering and machining, you are very talented!
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
@@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
Around 1991 I was a young Elecromechanical Apprentis. I had been an Auto mechanic prior to working in the motor shop. I had a few worm gears, and several motors under my belt. My boss began freaking out, when he came in and saw 2 Cyclogears, completely dissassembled on my bench. Closest he ever came to screaming,, he yelled,, "We DON'T WORK ON CYCLOGEARS!! We Never have!" Not knowing,, I asked Why? Because you can't get them back together! Too complicated! He shouted! These were something in the 180 to 1. Ratio, multi stack. But low powered,, like 1.5hp used to extend/retract Gym Bleachers. He paced back and forth as I changed the bad bearings, and put them both back together. He calmed down, as we successfully test ran the first one. When he came back and saw the second one running fine, he said,, "Well I guess We work on Cyclogears."😊 dude you're good 👍! Cheers!
Also, do NOT forget the harmonic drives, which are essentially the same thing, with an internal spline. We did these for all of the Apollo Moon landing LRV vehicles, for their wheel reduction (80-to-1). Those drives would still be useable if we could get some fresh batteries up to these LRVs. The internal gearing is still good to go, since it sits in a hydrated air cell. The outer part is lubricated by a Krytox metallic lube which will coat that gear set forever (since it evaporates over the surfaces). The Main problem would be the Parking Brake, which is a metal-to-metal interface, and is probably frozen together now in the hard vacuum. If a couple of Astronauts could go up there, with a manual Jack, and forcefully rotate one of the wheels, while the motor-controller was pushing it, they might be able to break these brakes loose, and these LRVs could be used again. The motor controller (aka DCE), has a current limiter to the motors, so cannot push more than a certain amount of torque. As such, manual assistance would probably be needed. PassItOn.
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
Pretendgineers are often the very best engineers having problem solved on the fly and learning from their mistakes. I would trust a pretendgineer over a real engineer any day. This is the first video of yours I have watched. You've gained a subscriber firstly for your humour and secondly for your impeccable engineering skills.
Between the ridiculous [not] engineering that went into this, the soldering iron mic, and the fact that you sent your first attempt all the way to IM for the box of shame...I'm subbing. First rate all the way. Well done, man.
Really good presentation. Stellar. Machining for zero backlash is insanely difficult. I've made some ACME mounts, but nothing that required that precision. Love the soldering microphone.. Lighting. comedy timing, just spot-on. Kudos!
Insanely difficult as in "impossible"? I just fell through a rabbit hole, and the first sign reads: "Nonlinear characteristics of gear pair considering fractal surface dynamic contact as internal excitation" Time-varying mesh stiffness, t-v temperature stiffness, gear pair meshing vibration, radial vibration, phase trajectory topology, bifurcation and chaos, correlation between all these parameters ... MY EYES!! :D
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
@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!
Coolant is your friend, you can use a spray bottle. Or brush with oil. A few things, this type of drive system is going to be loud compared to constantly meshed spiral cut gears. Also the lash in the gears is there for a reason, as the parts are in use they heat up and expand. Having them too tight will make it very tight and create wear. Also the gap keeps oil flinging in between the teeth. The teeth are also hardened so i have not finished your video yet but i dont see any plans for heat treatment.
Another thing, you have no vent, this will create pressure as it warms up and cools, you need a vent in and gearcase or transmission or the seals will blow out.
Loved this bro. Loved the humor. Loved the nerd talk. Loved the plot. I'm a moto sports enthusiast, as well as a self taught engineer/improvisionist, a welder and iron worker by trade, as well as a perfectionist with OCD. I'm super jelly and quite impressed with your machining tools and know-how when using them. I hope to build up to a level like this. I have a pretty modded out car myself on my quest for 400hp out of a turbo charged 1.6L. To summarize, I thought this video was awesome. Would love to see more, so needless to say, you got my sub/like. Best of luck on your quest for 250k subs mate. Cheers!

@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 TH-cam by people being, well people who can say what they want without consequences that it was basically automatic.
OK, so this has been recommended for a few days. Damn, TH-cam does know me better than my mum. This is as good as it gets. You got a new subscriber.
I really enjoy your sense of humor and talent.
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... 🙄😂

17:40. Good thing you had Leeloo to help you lift that new bandsaw.

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.

Man, I love your dry humor. Most will not get it unless they have ran into similar issues with projects. My muse is more along the lines of experimental electronic component builds(for example working on an experimental TEG that is entirely printable, it's very touchy. Junction points as small as 1 mil (mil as the measurement mil and not millimeters. Average human hair is 1 mil.) and up to 5 mil. Graphite, graphene, and conductive inks ranging from nickel to gold. Sensitive enough to use sun light to generate. I currently have to draw them out by hand for test models until I get the measurements within a working tolerance. Tedious does not even begin to describe it.), so even though I do not know many of the ins and outs of machining I certainly feel your pain. Keep it up, you are making great progress! Looking forward to further videos like this. You earned a subscriber.
It's so satisfying seeing you redo the same work over and over again so calmly and eventually get the right results.
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 . . . . :-)
What a beautiful piece of engineering.
ahh yess the casual cameo of one of my favorite machinists is top tier, also that lathe crash made my soul jump
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.
As one who is a DE and uses CATIA, I think it's wonderful how you brought your ideas to life. You appear to be very resourceful and creative.
The underscoring lesson here is to appreciate the importance of GD&T in your designs.
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 TH-cam.
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).
Do you have a link or keywords to find out more about that design of cycloidal reduction box?
@@Nedw Web search gets nothing (I tried "AXIAL cycloidal gearbox). The search latches on "cycloidal" & ignores "axial". I found about this in old optical catalog (for fine motion of optics without backlash). The benefit of this scheme is the ease of making if you have manual lathe & CNC milling machine. All of the "non-circular" elements are machined on a plane surface (simple cycloidal groove that ball bearings roll in). Calculating the CNC files is simple. It is the superposition of 2 circular motions: one is once around, & the other is multiple times around. One plate has path where the 2 rotations are the same direction (makes cycloid) & the other opposite rotations (makes hypocycloid). The (larger) radius of the once-around rotation & the (smaller) radius of the multiple-times around rotations are the same on the 2 mating surfaces. You need 3 plates (2 surfece-sets) total. The center plate is forced to orbit by eccentric. The ratio between plate 1 & plate 2 is different than that between 2 & 3 & in the opposite direction. For example, if ratio 1 is 15:1 & ratio 2 is 16:1 (reversed), the total ratio of 240:1. I do have CAD files of one I made experimentally. If you have place where I can send them, I offer them for you to look at.
Ironically, when I saw the thumbnail, I thought it was using ball bearings instead of rollers.
I found a patent for an "axial cycloid reducer", then hit a dead end.
I also came across magnetic cycloidal reducers, which are neat but have radial "engagement" not axial.
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?
@@phinox60because fractions are fucking stupid when you are trying to be precise.
@@Drazard womp womp. freedom system prevails.
@@Justin-lc8wk 95% of the world uses metric 😅
Man that song choice comes straight from love. This is brilliant.
I just watched inheritance machine and then came to him. The two are perfect for each other. I’ll now watch both.
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 👍
I hope the trend of makers sending Inheritance their scrapped parts catches on
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. :)
Like so many others, I didn’t know about PCBWays machining services. Best product placement I’ve seen in a LOOOOONG time.
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 TH-cam 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.

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
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 . . .
] 😅
Though in Sydney "internal nut" is a sort of sexual misadventure that'll land you in St Vincent's for the weekend.
If your audio was bad, I wouldn't be watching. You've learned the important lesson of having good audio. Bravo.
That handheld microphone paying for itself.
It is really, really hard to stop myself watching this video. I needed a break at 10:00 and struggled to avert the gaze until 24:00. I have finally done it and can make a cup of tea. What a content.
Speaking engineer to engineer:
A cyclodal drive is not backlash free by definition, it relies on the accuracy of your production tolerances.
In theory, the way the cyclodal drive works, you have a lot of points of contact at any given moment. Take in consideration production tolerances and the concept is heavily overdefined. This can only be made to work by having either compliance or a combination of certain production tolerances and a matching amount of clearance (play, thus backlash).
This said, a cyclodal drive is a very interesting gear mechanism, offering very high reduction for the volume it consumes.
The inherent low backlash is presumably due to having a high number of tolerance fields overlapping with their respective position errors, effectively lowering your effective clearance.
Anyway, great engineering and machining, you are very talented!
It's even funnier when you realise he is holding a soldering iron which actually has no mic attached 😂. Love your content!
23:07 this is a war crime
The soldering iron "mic" is a nice touch.
I was subconsciously waiting for him to suck on it like a hookah
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
Those were Winston Churchill's words when he was invading Norway, Dieppe and Alamein and Sicily despite huge troop losses.
Not only am I impressed with your project, I'm super impressed by your video edits, story telling and sound design! Great video!
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
Around 1991 I was a young Elecromechanical Apprentis. I had been an Auto mechanic prior to working in the motor shop. I had a few worm gears, and several motors under my belt. My boss began freaking out, when he came in and saw 2 Cyclogears, completely dissassembled on my bench. Closest he ever came to screaming,, he yelled,, "We DON'T WORK ON CYCLOGEARS!! We Never have!" Not knowing,, I asked Why? Because you can't get them back together! Too complicated! He shouted!
These were something in the 180 to 1. Ratio, multi stack. But low powered,, like 1.5hp used to extend/retract Gym Bleachers. He paced back and forth as I changed the bad bearings, and put them both back together. He calmed down, as we successfully test ran the first one. When he came back and saw the second one running fine, he said,, "Well I guess We work on Cyclogears."😊 dude you're good 👍! Cheers!
Very cool :)
This is a final test, a true engineer would never ever think of doing a cycloidal reduction himself. Never, no chance.
Awesome how positive you are thru all the hardship, a thing to adore
Oh boy, your videos are absolutely fantastic. The music, the tone, the subjects. I wish you the absolute best. Thank you very much.
Dude! You're married to Leeloo from Fifth Element!? Sweet! (also, cool project. loved the IM gag)
You got Leeloo The Fith Element to help unbox your bandsaw. Respect.
Came here to say this!
Milla Jovovich played the part of Leeloo

29:53 wait... you don't weigh in your offcuts and chips for scrap value?
You are probably the best Engineer by trade, than any engineer I've worked with that have degrees. Fantastic work!
Also, do NOT forget the harmonic drives, which are essentially the same thing, with an internal spline. We did these for all of the Apollo Moon landing LRV vehicles, for their wheel reduction (80-to-1). Those drives would still be useable if we could get some fresh batteries up to these LRVs. The internal gearing is still good to go, since it sits in a hydrated air cell. The outer part is lubricated by a Krytox metallic lube which will coat that gear set forever (since it evaporates over the surfaces). The Main problem would be the Parking Brake, which is a metal-to-metal interface, and is probably frozen together now in the hard vacuum. If a couple of Astronauts could go up there, with a manual Jack, and forcefully rotate one of the wheels, while the motor-controller was pushing it, they might be able to break these brakes loose, and these LRVs could be used again. The motor controller (aka DCE), has a current limiter to the motors, so cannot push more than a certain amount of torque. As such, manual assistance would probably be needed. PassItOn.
What I need from a gearbox is some more alcohol. Love your vids 😊
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
He should send the finished product to Elon Musk to fit into his rocket engines to reduce vibration.
I beleive it is in fact a "but"
Pretendgineers are often the very best engineers having problem solved on the fly and learning from their mistakes. I would trust a pretendgineer over a real engineer any day. This is the first video of yours I have watched. You've gained a subscriber firstly for your humour and secondly for your impeccable engineering skills.
Between the ridiculous [not] engineering that went into this, the soldering iron mic, and the fact that you sent your first attempt all the way to IM for the box of shame...I'm subbing. First rate all the way. Well done, man.
My friend - the little gems throughout your videos are fantastic. Truly a joy to watch.
Really good presentation. Stellar.
Machining for zero backlash is insanely difficult. I've made some ACME mounts, but nothing that required that precision.
Love the soldering microphone.. Lighting. comedy timing, just spot-on. Kudos!
Insanely difficult as in "impossible"?
I just fell through a rabbit hole, and the first sign reads: "Nonlinear characteristics of gear pair considering fractal surface dynamic contact as internal excitation"
Time-varying mesh stiffness, t-v temperature stiffness, gear pair meshing vibration, radial vibration, phase trajectory topology, bifurcation and chaos, correlation between all these parameters ... MY EYES!!
:D
i knew ive seen that wooden box before.... nice cameo. now we need some woodworker to make him a new (and definitely bigger) box of shame,
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
@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!
I deeply admire your dedication to perfection. SO much work. Well Done!!!
Coolant is your friend, you can use a spray bottle. Or brush with oil. A few things, this type of drive system is going to be loud compared to constantly meshed spiral cut gears. Also the lash in the gears is there for a reason, as the parts are in use they heat up and expand. Having them too tight will make it very tight and create wear. Also the gap keeps oil flinging in between the teeth. The teeth are also hardened so i have not finished your video yet but i dont see any plans for heat treatment.
Another thing, you have no vent, this will create pressure as it warms up and cools, you need a vent in and gearcase or transmission or the seals will blow out.
That backlash is nothing to worry about. Get it hot and then retest it bet its tight.
Loved this bro. Loved the humor. Loved the nerd talk. Loved the plot. I'm a moto sports enthusiast, as well as a self taught engineer/improvisionist, a welder and iron worker by trade, as well as a perfectionist with OCD. I'm super jelly and quite impressed with your machining tools and know-how when using them. I hope to build up to a level like this. I have a pretty modded out car myself on my quest for 400hp out of a turbo charged 1.6L. To summarize, I thought this video was awesome. Would love to see more, so needless to say, you got my sub/like. Best of luck on your quest for 250k subs mate. Cheers!
Watched a few of ur vids this afternoon with a cup of tea and I'm genuinely in a much better mood. Brilliant stuff, cheers :)
Mate I love it.. it's genuis! And to think these are prototypes is crazy!!
the time you spent making this video is appreciated
i liked you as soon as you started talking. I like the way you do things, YOU FIND YOUR OWN WAYS. very aware of what may come if you were to go a certain route "foresee"
