Thanks For Watching!
Man it was a real pleasure, I chuckled several times and on top of that you addressed all my questions!
You are brilliant
Send the nut and bolt to AvE for torque testing
I 2nd that motion. I would be interested in seeing what the clamping force is on that bolt. I'de bet it's a real "skookum choo-cher" ...pun intended
u are awesome...
This is nuts
Sorry, I don't care for Twitter. RUclips and Instagram are all the social media I use.
Great video on the recirculating bearings!
That good thinking
new kinda Ferris wheel
Need to build a bike with that gear
Did you ever try to revisit this concept using threaded or ribbed rollers like in an epicyclic screw mechanism? Recirculating BBs have a stronger tendency to catch and wear or fall out and scatter everywhere than rollers tend to...
So instead of firing a grappling hook at the at at's legs and flying around it until it tripped, all Luke had to do was shoot out the little hook grabber ball channel feeder thingy and the at-at would have lost its marbles and tripped over its own balls.
I don't do twitter, but I did just subscribe....
At-at (aye tee aye tee) is the proper way to say it becaus it's an acronym of All Terrain Armoured Transport, but I don't think it would be out of place called an at at because the HMMWV (high mobility multipurpose wheeled vehicle) was called a hummvee by the guys who used them.
It's pronounced "A" "T" "A" "T".
Like how you say the "B" "F" 109 in a Bf109 German fighter.
Sorry its the nerd in me.
Very cool though!
ImaFurby Gaming yeah next you're gonna tell us r2d2 is actually spelled Artoo Deetoo. Friggin' nerds. Lol
Pronounced, Yes.
Spelled, Absolutely not lol
Best Fighter 109
Agreed; AT-AT is definitely "Aytee-Aytee", much like AT-ST is "Aytee-Esstee" Never heard anyone refer to AT-ST as "Atst" Ahen you see AT-AT, just think 80-80
@@aomimezura11 Actually, if you go by the 1970s _Star Wars Storybook_ , R2-D2 is spelled Artoo-Deetoo, and C-3PO is spelled See-Threepio. Granted, it was more for the benefit of children, so they'd know how to pronounce it phonetically.
do you have a video on how to design this? i need to make one for a project but have to be specific measurements :D great video
Someone has been watching a lot of AvE lol
I can't help it..
who can?
It's vurking!
@Overspray Collector blasphemy. Gtfo
Ingenious! Really great job!
What a size of balls for lead screw T8
What if you route the balls to a second ballscrew race? The balls being pushed out by the first ballscrew will force the second ballscrew to turn! Or perhaps use the stream of balls to push a gear around like a wormscrew? Also, I suggest stretching the nut thread pitch instead of the screw, so you can user a standard thread pitch for the screw and even use a standard metal screw if you want.
Another possibility is to use 2 ballscrews threaded together with a thread pitch different than the screw, so that they will function together like an anti-backlash nut, and also have twice the strength. Or maybe just use less races on either side to keep it close to the same size.
Exactly what I was looking for... Thanks for explaining stuff.... You are awesome! Well done and more power to you!
great ideas!...your a smart man and help alot of projects
So you could make that larger scale and mount a bike wheel for a hubless wheel
We are listening! Keep up the great content. It's refreshing to have somebody producing original videos that contain thoughts that I won't really find on any other channel. You're really making me want to erase my christmas list and just get a 3d printer.
G Elerson I second this, I'm a brand new sub and I am very impressed. Also love he's a fan of Ave and not likely to become an Amazon shill LMAO
I appreciate the engineering that goes into this, but couldn't you accomplish the same thing with a regular bearing in a ring shape, and attach the block to the outside, and the base to the inside?
You also get this in the steering mechanism of a car. Pretty awesome stuff...
First time too tight second time alright 😂
Like my girlfriend.
Fantastic work. Love it.
These things are also incredibly strong. C-130's use ballscrews on the main landing gear both for moving the gear up and down, and for transferring weight to the struts, ballscrews are also used to move the flaps up and down.
What kind of bb's are those? ⭐🙂👍
Neat stuff!
I like the ball screw trick of stretching the treaded rod, but I think that means that the load is only passing through a couple of the balls. With metal ball screws, people get rid of the backlash by taking two ball nuts and threading them up to and against each other. That way, at least half of your balls are engaged at any one time.
This is some really good content, got my neurons firing, subbed and heading over to Patreon!
Hi, what is the tolerance that you used in the bering design? How much bigger is the bering Chanel from the bb?
I can tell someone is also a fan of AvE
Amazing video man, love the creativity.
Got my sub for that Ave reference lol
Great vid and thank you for taking the time to do so!
8:25 yes so its not same pitch,but its not matter bb roll in there.only in and out hole is not align,but better make correct size on 3d printer xD
Nylon bbs?
It's not "At at"... it "AT-AT" AayTee-AayTee or sounds like 80-80!
It's an abbreviation for "[A]ll [T]errain - [A]rmored [T]ransport".
All letters are in Caps / Uppercase which means it's a Hard Sound "AT-AT" and not a soft "at-at". ;)
Mind if I print you a cover for that outlet?
"A linear rail bearing has no backlash"
No shit.
You should 3D print a pneumatically powered steam engine generator setup we have the Piston to only move so fast but the generator is screaming putting out a lot of juice electricity that is if you like gear ratios so much try to do something like that
Great channel, you deserve more subs.
amazing idea
Who'ed thought someone could make gears interesting? Well, you did!
Great job. Informative and entertaining.
Following you on twitter now.
I was just gonna say he must watch AvE but someone beat me to it. I bet if ya put a little schmoo in that jeezlus thing it vould verk great!!!
what 3d printer do you use?
I usually do not expect to see an Empire technician show off Empire technologies around here. Is it possible that you disclose the science behind the twin ion engine's solar wings?
I think some gun turrets had a partial slew ring bearing that worked in the same way as the first one shown. Used because it's a bit smaller and lighter than one that goes all the way around the entire guide track. Might be able to see some good examples on WWI aircraft.
This changes everything we ever knew about 3d printed gears! I mean you can use that radial race... thing, for mounting planetary gears perhaps or even put a crown gear on one side to transmit power to another gear positioned at a 90 on the bearing housing. Killer video!
Interesting thoughts. Ill look into that some more.
Sorry I don't print or do gear stuff. Wish I could do more than bark commands at you haha
Also, a worm drive is applicable
Yeah, someone else mentioned that too. My mind is still chugging away on how to keep the balls in the proper place.
interesting idea. I am in the middle of designing a planetary gear. I.will investigate this idea in fusion, and if I have enough space I will implement it. I am quite constrained in space that I can use.
Look into how a swing bearing in an excavator works. It's very similar but fully circular and encapsulated.
Good old Ave!
So he rediscovered how a pre-rack & pinion steering box works.
wooo this is so cool! ..... gives me a ton of ideas of using recirculating bearings :D
Thats pretty good
amazing design :)
Super curious to see a 3D printer using that printed ball screw for a Z axis... that'd be, kinda awesome...
As nerdy as it may be, but that semi circle thing has me curious as to how you can apply that to a 'rotating axe' like Draven from League of Legends uses, maybe licking teeth along the track to prevent reversal of the rotation?
Full scale on a bike
Recirculating balls? You should probably see a doctor about that.
+Godfrey Poon that’s a good point
can you make a big linear motion on office chair insted fore the weels that damage the flore, thosen line up , damageding cabels , and maby rolover friends foot. if hvae tracks on the flore mabe it wold be smoth and alsaw thit a lock whit a padle to unlock
.
Awesome!
Can you use a resin printer with tough resin and print small 6" inch sections with a hole in the middle and join them together with drill rod to make a long ball screw?
That would be fun as a bike wheel.
Nice Video💯
All that's missing is a ball transfer unit! ( en.wikipedia.org/wiki/Ball_transfer_unit#/media/File:BallTransferUnitCrossSection.png ) have you considered making one? :)
Are the ballscrew and screwrod precise enough that you could replace the metal screwrods and stuff on a 3d printer with them and bring us closer to the dream of a 3d printer that can fully print itself?
Has NASA been in touch with you yet? You are eff'n brilliant. Get your engineering degree and then school your profs.
Biggest issue will be the metal BB' will chew through the plastic very quickly under any loads. This is why metal bearing races are hardened steel, to stop the load forcing the balls to grind the metal away.
Using plastic BB's may be better for longevity, though they will not perform as well.
Any chance you could print a full linear axis using this nut and bolt, and test it out with a stepper? A reprap machine using this system could throw away most of the metal bits required.
You are doing some amazing stuff! I would really like to try your ball screw creation in a 3d printed, 3d printer! Just not sure how to adjust my firmware, or what kind of resolution improvements I would get, if any. Keep up the great work! Everyone should check out his 3d printed winch test video! It's amazing how much they could lift!
very interesting
thanks
It would be interesting to see how you designed it in fusion 360. I would wach it and lirn something new. Great job btw.
A Small Scale STAR WARS ATAT Walker.. Would Be Awesomeness Hands Down.. There Are A Lot Of, - *(STAR WARS NERDIY FAN'S) Out Here.. May The Force Be With You Always..
BBs everywhere.. 🤣🤣🤣
Would you make a tutorial about designing the bolt channels in Fusion360? Or at least release the Fusion360 file so I can check the storyline. Thanks and keep up with the great work you are doing!
Nobody uses twitter...
Can you explain how you deigned and printed the circulating bearings?
I am interested in internal structures modeled in Fusion360, then conserved and printed in 3d printing
now we need a 3d printed linear rail
Love the video, very clever. I feel like every day I see another clever application for 3D printing. Also, thank you so much for publishing all your designs for free online. Really is for the good of the community. Do you/would you ever consider taking on projects?
I like taking on projects when I'm inspired to do so. otherwise it feels too much like work
Well my immediate thought when looking at this was an RIS-RIS recoil sled mount using one, or a pair, of RC car shocks. You've got the smooth but tight linear motion down, and it only would need the mounts and a spring-damper unit to function. Such a system could protect delicate electronics, optics, or whatever else on high power rifles.
"First time too tight, second time alright"... that's what I told her.
Wouldn't the 3 mm stretched rod, giving you zero backlash, be the cause of the nut spinning freely?
You say AT-AT but everyone else says AT-AT ..lol
Is there any way I could print that circular linear bearing at 100mm diameter. I only have a Monoprice select mini so size limited.
Nice
What're the tolerances of BBs? I know of some youtubers using marbles in the past for bearings, and marbles have a lot of variance in diameters, and sometimes even in shape.
7:00 Good bye, little balls!
So, is this an AvE tribute? :D cuz I lost count on the references! ;) Anyway, LOVE your slewing unit idea! Also: new twitter follower!
Sorry I am not a twiter!
LoL
I follow you here.
A T A T, NOT ATAT
Sorry I'll subscribe, but I don't Twitter. LoL love the videos and thorough exclamation of each item. I'll be printing these for sure
I don't think you mentioned it at all but did I see a plug on the nut for adding bearings into the system into the return channel? if not it may be something that you may want to think about to make loading the bearings easier. great design though. and great video. thanks for sharing!
I've never actually owned a real ball screw, but I have seen that, would be a really nice way to load the bearings into it.
Gear Down For What? I have never seen one other than yours. I just saw what looked like a dimple in the side of the nut and assumed that that would be what it was and what it would be for... like I said though it may make it easier to fill up with bearings.
Gear Down For What? I would think it would make it easier with the other one too. if just a few bearings short and it would be louder if Nothing else... with a plug on top that goes into the return channel and you could load it with the proper amount much easier...
80 80
ATAT is an initialism like C3PO or R2D2. It’s just: (Aey-Tee Aey-Tee)
Damn this makes me feel old!
It's pronounced ay tee ay tee
I don’t know what’s more upsetting. The fact that this man doesn’t know how to say AT AT, or that I can’t teach him. 😭
Your saying it wrong....not at at...lol
These are awesome! Could you make a nonlinear linear bearing that could change angles like train cars or rollercoaster cars? It would allow for tracks that aren't constant. Oh and I followed you on Twitter!
Thanks! Ill look into it
Looking at the title, I thought this was Colin Furze's AT-AT build
but I'm not on twitter.....im watching though
