I don't think people realize the sheer amount of technical knowledge that goes into designing and machining these parts you make. Plus you do it on DIY machines in your shed! Great work man, keep it up!
Wait he made those milling machines? Omg lol
JohnnyQ90! On youtube is who you're referring to with the RC car transmission!
Johnny Q is a freaking genius.
I thought the same
yeah thats who i was thinkin too
Beat me to it, hes one smart dude I take a lot away from all these guys videos
That is exactly who I thought of when he said "another youtuber who bought an RC car with a 3 speed transmission". I watched that episode. And this is hella neat to see it scaled up!
i love how the ending was done in a "This old tony" style. by talking with his hands over a workbench.
Not just the ending. I assumed it was part of TOT's go-kart series from the thumbnail, and was really confused bout how I hadn't seen it in my subs at first.
Haha he should have a scotchbrite pad just laying off to the side!
He doesn’t have a camera man please understand it but he showed the old tony style on camera watch again
I like that he didn't explain it as he was working on it it gave the chance to try and figure out how it worked then he explained it fore anyone that didn't understand it
Kudos to your artistic director. You had a "Make it Extreme" vibe going on in this one; minus the heavy metal music. Very nice.
Artistic director?? Lol
I think you will need something to absorb the shock when 2nd Gear engages.
Maybe a v-belt between engine and transmission or the shock absorber from a small car clutch ( the inner section of the clutch disk with 4 radial coil springs) or a combination of both, just to give the engine at least a fraction of a second to slow down.
otherwise something will break...
Watching the milling an fab is so calming with the music. If it was on tv it would be backed with death metal.
then you make like AVEs machining videos, he uses classical music. more enjoyable then this hyped up tv stuff
As a machinist and small engine enthusiast, this is one of my favorite channels
This is fantastic! Essentially made a centrifugal clutch for gears! It’s going to be fun figuring out the correct spring ratio and finding out how much torque the one way bearings can handle. Should be quite a bit if I remember how they work.
old sears minibikes had a similar setup, just with two centrifugal clutches and a sprag. i'd imagine this setup will be pretty jarring going between high and low, the two clutch method that sears used was very smooth
The music choice was something else and interesting, I like it a lot.
Reminds me of a Christmas movie
The music is the one thing I hate about this channel. I would much rather just hear machining noises, or better yet, talking about what he's doing. The crappy music loops that so many people use drive me nuts. I had to skip ahead to the end after just a few minutes.
@@Snugglez187 I think music can go a long way to make the vids seem more professional.
@@Snugglez187 try muting. It’s not about the “music”.
Its impressive that homemade lathe can be so accurate over a long distance like that shaft.
Love the music selection. The combination of fabrication with the music is calming.
You could also use a centrifugal clutch for second gear, which would be easier to build and tune 😉
I was looking at using similar one way bearings on a kart but the torque limit on them is basically nothing. I'm very interested to see how these hold up! Also on most centrifugal sprag two speed gear setups have the sprag/dog mechanism on the driven shaft(in this case the axle) and not the driver shaft. If you have problems with it shifting into second and right back, or not staying in second properly then you might want to consider this. RC two speeds have that setup where the sprag/dog is on the spur gear (driven side) and not the pinion gear (driver side)
Those one way bearings won't last hardly at all. They'll immediately break.
I was gunna comment this too, the one way clutch should be on the wheel axle side so that vehicle speed determines the shift point not the engine rpm. Else like you said, if you're trying to climb a hill or something and need more rpm and power its going to upshift when you don't want it to, lowering your wheel torque.
Thought the exact same thing after finishing the video. Those one way bearings will slip if they see any real torque and he built the whole system on the wrong end. It needs to be dependent on wheel speed not engine rpm to work correctly.
first gear could use the spring loaded lever, just sprung out instead of in.
WOW!!! That's awesome!! I'm thrilled that there is now a second two-speed transmission video out!!!
its about time some one builds something thats been in the rc world for years cant wait to see it used on one of your builds
The feeler gauge springs is genius!
Brilliant!!! Can't wait to see it work!!!
How is this two days ago?
@@ethan9659 I think some people can get early access to videos if they have a certain link to it
@@carsonhendee919 thanks, I was pretty confused
@@ethan9659 No problem
I’m a machinist. This is certifiable nice work. You did a lot of thinking ahead building that pawl. I like your solution to match drilling the hinge pin too. Grinding a clearance notch so you can drill the hole using the pawl as a drill fixture. So what else, you say? I say I like it.
This is called Intellectual Horsepower.
Somebody get this man a brass hammer lol. Using a claw hammer in the shop is never the right option, unless you're fixing the roof or something
I was wondering why he didn't press them in.
It's about force and how much you use.
Somebody get this man some cutting fluid.
@@Muglez14 How about a parting tool also?
@@norsevikingsir4932 not quite, you can still split a race with a hardened steel hammer with little force. The softer material gives you the ability to give a stronger strike without the increased risk of damaging your work. That being said, a 4lb dead blow is really all you need on bearings that size.
your videos are getting towards this old tony spec with that amount of machining bud. love your work.
finally, someone who understands the movement in music. Calming, yet inspiring!
Don't know to be more impressed with the fab skills or the video filming/editing process. Very well done.
Just glanced at the thumbnail and thought it was a This Old Tony vid, clicked on it thinking "This sounds like something rather b welding is going to be interested in". Pleasantly surprised, nice work man.
Basically how a Tmaxx transmission works. Well RC car transmissions in general. Pretty sweet man!
Bloody Brilliant Rather B! I can see your next step right now! At the moment you have to pull the whole shebang apart to "toon" it. If you were to make your spring heavier, and include a very short coil spring under the head of it's holding down screw, you could "toon" it through a hole in it's sprocket boss. you may need two screws and holes, or some other method of keeping the spring captive, so it doesn't rotate.
I remember when you built the manual and I was blown away, thought it was ingenious.
Now homeboy's like that was so old, watch this.
Great editing and machining!
I really dug the music. It gave your video almost an epic film quality. Quite an interesting design. Can't wait to see what you put it on!
That thing is going to be sick
The stuff you make amazes me man! So talented!
I love the backround music😂❤️
A similar transmission design was used in the king midget cars. You may want to add a second locking pawl to your high gear as that first one may be too weak on its own (under load at peak torque it may fail).
Another way to make this transmission is with 2 centrifugal clutches (2 separate engagement rpms ex. 1600 rpm for low speed 2500rpm for high speed) a 1 one way clutch sprocket (low speed the one way clutch prevents burning the low speed centrifugal clutch shoes when in high gear) and a fixed high speed sprocket
This was a brilliant video, thank you so much. I thoroughly enjoyed the fact that I didn't have a clue what you were doing until the end!
that was a super satisfying video to watch and the way you explained every thing was easy to under stand. well done.
Absolutely BRILLIANT!!!
Just adding in my own compliments on the 2 speed, and definitely for the editing and music on this one.
I came for the new 2 speed, and stayed for every second of the beautiful video. Very well done sir!
This is quality work! Now just imagine what the 16 people who disliked this video could do.
It’s 35 now
Could be the exact number of folks who know 1st will shatter
@@jacobpeterson8270 Now its 45.
@@dylanzrim3635 If you build it out of the wrong steel it will ! This is actually a very old concept .
Great stuff man. You’ve always been a little ahead of the guys doing similar stuff with your lathe work. Your machining skills shine in stuff like this 👍🏼
Dude ! You stepped it up with this video. Your lathe skills are improving ! It made me start searching for a lathe of my own . Keep up the awesome work, and the videos ! Thanks
Absolutely genius design! Can't wait to see it on a machine
WOW, a lot of engineering went into that! Way back in the 60's, Rupp had a 2 speed automatic "transmission" on their TT500 mini bike. Theirs had a standard centrifugal clutch on the engine that had dual #35 chain sprockets on it. A pair of chains went to a jackshaft, one to a one way with a large sprocket (low gear) and the 2nd went to another centrifugal clutch with a smaller sprocket on it which was 2nd gear. There was only one main chain to the rear wheel. When the high gear clutch engaged the jackshaft sped up and the one way released. Whomever hires you will be lucky!!!
the right way , the centrifugal will buffer or cushion the shift ,,,this will shift like a bomb
Awesome video! Thanks for showing us your hard work!
Well done! That set up is Dope! You have upped your machinist skills. Your ready for another lathe.
Like the design. Very interesting editing style this week. Quite like it 👍
Nice job Chris! Great video and build - I too agree, love the music!!! Got to say young man, I've been following for quite a few years now and everything you do just gets better!! Keep up the great work, solid props you are due! Big fan from Tropical Cleveland OH LOL 🤣
Wow, Amazing and aspiring!! Thanks for the awesome content you provide!
Damn dude, this is impressive craftsmanship! There are other gokart youtubers out there but you're a level up (or two) !
Very nice video. I really like the different style and especially the chill music. Thanks !
Just like my revo! 👍 Frickin awesome
Dude I am loving this old Tony vibe going on. And I love the music
This is very cool. The design and machining are very impressive.
Was gonna say, just like an RC car gearbox. Good work!
Just in the future, try and turn the ID and OD in the same setup so they will be parallel to each other. Anytime you remove part from the work holding you add misalignment, can never get totally true again with indicating in, might only be a few tenths but everything helps! Love the channel, keep up the good work!
awesome! the easygoing music was nice with morning coffee as well.
This is awesome! Simular concept to centrifugal clutch.. Curious to see if it’s going to be a rough engagement. Keep em comin man!
Awesome engineering skills, and a super chilly video!!!
Love this, awesome job!
Beautiful machine work...always great to watch the things you can do (that I never thought of) on your lathe and mill.
Great design. Seems much better than using a second centrifugal clutch that's just going to slip until it finally locks on that we mortals without machinery to build such devices have to stick with.
It was your two speed transmission that brought me to your channel in the first place...nice to see it come around again, new and improved!
Amazing work once again, well done.
Workshop sound together with backgroud music is very nice
That's a really interesting idea for a go-kart transmission, I hope it works out. Excellent choice of music by the way, it really added something to the video.
Man this is genius !!!
Congratulations !
Love it!! Nice work!!
I could watch content like this for hours, awesome job creating that. I just hope it doesn't fail right away, it seems that little hinge has a hell of a lot of forces acting on it, but what do I know lol
GENIUS ! I really enjoy these milling videos, as boring as they may seem, the time lapse makes it look easy, would like to see a real time clock !
Milling ain't boring lathes are boring. Haha pun intended.
really enjoyed the build Chris 👍
You need a parting tool. They aren't expensive. Great job.
Super creative, great vid.
Love the music, very soothing
Excited to see how this will work on a project, good stuff
Excellent, really enjoyed the music.
Holy crap. You never cease to amaze me keep it up brother
Fine job, whatever the out come. Color me impressed.
Nice work.!!!! Thanks for sharing.
This was awesome! Can't wait to see it on something.
Great build.
Great video, machining + tunes 👍👍😁
Nice work. Love the music choise
Great video. Loved the background music to go with the awesome machining. Just subscribed to your channel!
I love the concept I just worry about the strength of it. For an rc car yes but a go cart with some real weight and torque behind it i can see some stuff sheering. Can't wait to see it in action. Awesome video.
Nice job man. That is a really cool design.
I really liked the music. Very peaceful video.
Awesome! I can’t wait to see it on a project. Very cool 😎
Chris i like the music choice for this video very enjoyable to watch and listen ad you work.
Gonna be cool to see on a cart...I'm excited
dude!
this video was very satisfying to watch!
also this is genius man! great job cant wait to see it in use
Excellent work,love the content.
Awesome idea!
Love It dude ,Keep On The Good work !
this project right here is an example of your work you dare to build things that most people would never even think about building so the never go any further you do and for that i see you going farther than most if you don't have it you build it i see people that have huge shops with all the tools but they lack one thing a mind that knows how to think of the next better way and the passion to drive you to get it done i wouldn't change a thing you are doing i think truly you keep doing things you're way and i know you are right you will be the best and i see you doing that great job buddy you are going places
Someone is improving their editing skills 👏
Amazing idea. I see a big company stealing this after redesign... Keep it going Chris! Your builds are next lvl and machine skills are out of this world!!!
nice little system , especially if you want to combine both systems for both auto and manual gear selections . i can see applications for going to a awd or 4x4 as well. thanks for the videos
Legend has it that he is the only man in the world able to make a straight cut with a hacksaw 😂
Ever heard of Allen Millyard?
@@Bubaaak yeah he sliced metal like onion
One of your best videos, you must have had that one on the backburner for while. I dig the classical piano.
This is the good stuff, love it!!
I'm really eager to see this put to use on a go kart!
That will be cool to see in the testing phase!
