Such a brilliant video, wasn't a subscriber but knew of you through Penny Pincher and Greg. The editing, the camera angles, everything was brilliant. You didn't need anymore talking in the video as it spoke for itself. I could have watch it for hours!!
Very cool! What is the total cost going to end up on this? $450 just in the case? Is there a "off the shelf" or adaptable option for the price you will end up spending? Not knocking your work, totally understand wanting to build one yourself, just wondered what options are out there.
might wanna ream out the non-keyed sprockets, and put some bronze bushings with spiral oil grooves in them. since the gokart shafts are hardened steel, I'm not sure annealed steel will last super long, even with an oil bath. otherwise, your transmission is looking pretty good! can't wait to see you try and figure out the shift linkage... 😺
The bronze bushing will wear out the harden steel shaft before it sacrifices itself. So actually the softened steel on the hardened steel is a better combo.
@@johnwalker7592 Bronze bushings are softer than hardened steel, so how will that work. The only time I ever see shaft or sprocket/gear wear on their bore is when the bush is gone, because no one lubed it or checked it, and it's steel on steel. The only time I have ever seen a bush wear out a shaft was when I was dealing with a really hard bronze like aluminium bronze. Normal composition bronze wont wear hardened steel in my experience. They are sacrificial, made to be that way. You might have a different experience, tell me if you do please. Always keen to learn
I've been an engineer for 36 years fabricating welding and machining and you are well wise beyond your years, can't wait for the selector set up a pleasure to watch keep it up sir.
Awesome job !!!. But can I offer a bit of advice try putting a slit bevel on the shifter cogs contact teeth so they will mesh in out better when changing gears. Might also want reharden those gears and install bushings were moving on shaft . Not being negative just want to help
i've been watching you for a while now and it's cool to see how you're growing, both in complexity of your projects and in machining and welding practices.... Keep up on doing what you're doing, bro. Hugs from Brazil.
@@mikeisaac3826 He is referring to the first "your" (in "Your such a badass!"), where "you're" would be the correct one. The second use is correct though, as you very well spotted.
Thyldor owwwww fuck off nobody gives a shit (“you’re”) a dick for encouraging twats like him. People don’t care for correct grammar when they are typing a RU-vid comment. So don’t be a dick.
The non-key'd gears have to have bronze bushings or something in them at least, I dont think they'll last long without it, and also transmission shafts are SUPER smoothe, like ground on a surface grinder and are hardened, Go-Kart axles will last 5 minutes-
not saying ur wrong. but he did make a 2 speed one without being in a box of oil or having any fancy seals. and that thing is still running strong after 1-2 years
@@nickkaarslev290 His other ones (like all his Buggies) are built for RU-vid videos, you see how they just sit for months and years under Tarps out in the rain, on the side of the shed, not used? They seem to get very little actual hours on them- Also, those other sliding-pin 2-speed designs dont have gears on spinning shafts that make tons of friction between each gear and the shaft theyre on...... they are all keyed to the shafts
@@carabela125 a box of oil doesnt make super soft go-kart axles withstand the friction and forces of high speed spinning mild steel (soft) bushings on them much less of a grenade........ ALL transmissions (even the crappy ones in a Lawn tractor) have hardened gears and ground, hardened shafts, and bronze bushings-
Its grayt, but yor fogot about bearing between axis and gear wheels, and if yor assemling in this afer 10 - 30 km you have broen you gear box, sorry about mistayks I'm not well know english, but I'm advanst in gear box
Definitely. I loved the video, but I always want to understand how things work, and that video just shows how you put the pieces together, not how that transmission will function. Other than that, though, great video. Awesome machining set-up.
Muito bom amigo!!!Excelente projeto!!!Gosto muito de ver você trabalhando em seu torno caseiro,e para falar a verdade seu canal que me incentivou a fazer meu torno caseiro!!!Só espero que meu torno fique bom que nem o seu!!!Obrigado amigo,Like!!!Saudações do Brasil!!!
I know I'm late and you probably won't see this, but, this was the most satisfying video I've ever seen on RU-vid. If you're stressed, watch this video and all that stress will melt away. Fantastic work on the parts and the editing!
Please can someone donate a ball peen hammer to this guy. Now I'm trying to figure how he is going to shift the dogs while keeping all the other in their place.
This was one of my FAVORITE videos! You should really see this thing through! I have gone back and rewatched it three or four times because I am planning to make a simple little gearbox that is hopefully super duper overbuilt for my projects!!
I'm 53 and started out like you... wanting to design and make my own parts for projects. I wasn't into "Sports", and I'm still NOT. I don't waste my time with that bullshit. I like working with my hands and being outside. I love it when folks say that it can't be fixed, or it can't be done. Makes me laugh. Triple thumbs up!!!
front wheel drive transmission. cut the bell housing off, use the differential outputs. Voila. 5 forward gears, reverse and a differential. easy peasy.
@@MarksGoneWicked posi traction is a trademark owned by GM, it means limited slip differential. No one said anything about making the vehicle front wheel drive. Its about using a transaxle from a FWD car to give your RWD cart everything it needs.. You could use an Albins ST6 if you got 30 grande to drop on a transaxle, or just heed the advice of those who know what they are talking about. ;)
@@MarksGoneWicked Its common place to use Porsche/VW transaxle in rear/rear buggies....but FWD transaxle's are more compact. www.westgarage.co.uk/Projects/royale1_files/page1_2.jpg
You don’t have to apologize for lack of explanation, video length, or other. Forget all that crap, just keep doing you, if it’s from your heart, people will appreciate it. I say concentrate on the meat and potatoes, and less on the bread and butter, if that makes sense! I enjoy watching others be innovative, hats off my friend.
Don't ever assume that because you know something, that your viewers do. I bet there is a large percentage of your viewers who only have a vague understanding how a transmission works if that. Explaining how it works in a separate video would be cool.
I think it’s not to long if someone gets tired of watching theye can leav mite as well get munny for what u recorded And also I think 30min is not 2long
Not obvious to me what is driving what. Nice video of you machining stuff though 😀 Remember our screens are small and flat. Why did you take the gear out of the lathe when you started boring it only to bore it in the mill with a boring head? I have always found boring round things in the lathe way more accurate.
Holy crap, absolutely amazing! I’m definitely subscribing to your channel. I know this is probably a really novice question, but what’s the stand that spins that you are using to TIG weld on? Is that something you made?
Muito bom amigo , eu também gosto de inventar coisa por isso me tornei um cridor de conteudo ,só que não tenho um torno ,mas se deus quiser eu vou comprar um para facilitar minha idéis.
whew, I remember paying those aluminum prices. After years of searching I found a local supplier (kind of local) that has drops similar to those sizes for $2.50/lb
Hi Humberto I have just finished watching my first video of yours. It blew me away all the projects you have produced like building your own lathe etc, & your only a young man what will you be producing when you get to my age. I cringed when I saw you using a file on your lathe without a handle on it, yes I have taken a workmate to HOSPITAL with the file buried in his gut. Find your nearest Industrial engineering supplier & order a WARDING file. It will be approximately 1/8" thick & tapering to a blunt point over the last third. You will understand why I make this recommendation after you use it on your lathe. Get a piece of bright steel flat say 1/2" thick by 1 1/2" get a 5/16 th UNF or BSF bolt about 5"to 6" long drill & tap about 1/2 from the end of your flat bright. Go to your lathe & put a dead centre in your tail stock bring your tail stock up to your cross slide thread the bolt into the thread of the flat with a nut on the bolt leaving about 3/16" th of exposed thread
Cant you just buy those LOVEJOY or flex couplers at Princess Auto? Then you wouldnt have to machine all those parts down like that, just sayin. www.princessauto.com/en/search?Dy=1&Nty=1&Ntt=flex+coupler
yea Im sure he will have some sort of reduction before it even gets to the trany, maybe not but it does look like even first gear is a crazy speed if directly engaged to the power source. lookin forward to how it all goes together.
Mad skills..I need your help on my project. About gear ⚙️ ratio. Mill work. Some welding. Do you do side work. I'm not sure where you are located. But I could ship you supplies u fab fix and reship ? I just need them 1 inch key sockets to take a special spline sprocket. And some u joints to 1 inch key socket..same.as u welded the gear ⚙️ mount to..
Ah... Don't the shift dogs need something to transfer power, I.E. splines..? I suppose you could do it with keyways or set screws, but.... That would pretty seriously compromise strength.
I just binge people I am subbed to every now and again and rarely keep up with their videos when they release... I see this video in the related and I'm all OHH this seems cool! few minutes in I'm like, Eh I should sub before I forget... Go to click sub... I'm already subbed? What? I check the name... Aw snap it is this guy hah.
Hey guy..both of your designs are ingenious. . I'm making it out of wood to better understand.b4 I make metal .your double L couples have no outer rim for the shifter to push like on your 2 speed tran...ijs👍👍👍👍a hub with teeth...on both sides..maybe??
I really wanna do this, I like the idea of having added control over my gear ratios but it would be a lot heavier than just getting an engine with a transmission right?
Wow that aint much metal for 450 bucks. I've got a bunch of better stuff and can't get rid of it but mine is 18 inches by 20 foot each and 5/8" thick, if you want some let me know cuz I'll give you a way better deal that that. Damn those companies sure as hell are greedy bastards.
Part 2... Doctors re build your arm after it gets dragged into your lathe. Be careful man, I know you've explained this before and hate this kind of comment. However it only takes a second and you're fucked. Think about future wanks bro.
450$ just in plate sheet. you dum dum? you could have bought a scrap car for 200$ and take ALL the parts on it from the 5speed transmission with differential to the wiper motor and heater core.
that gear @ 7m40 is comparable to the ones that are used in the Bugatti Veyron, so massive. your kart happens to have 1001 ps? you should have taken a look at Evenrude outboard motors, in the tail there are the parts to "shift" gears, you might could use these. nice lathe, shows if you don't have the resources ingenuity takes over. nevertheless awesome job.
Cool design but FYI the gears and dogs on that thing are about as big as the NASCAR transmission I watched a teardown video for recently, so you could probably put that thing in a Honda Civic when it's all said and done. To be fair, a Civic is basically a go-kart.
450 dollars for that small amount of aluminum just goes to show how ape-shit the world is getting. That price is ridiculous. On a different note, though, I'm curious as to what you're gonna use to engage those sprags. Are you gonna use a compound fork setup or something? Building the gear-train is the easy part. Figuring out how you're gonna control it is not gonna be easy, especially to end up with a design that's reliable.
Dam phone's where was I oh that's right Mark your center hight on the shank of your bolt & cut the bolt to that hight give yourself about 1/8" th clearance on the under side use the nut to lock the bolt at the center height. You can setup your tooling in seconds and you don't have to scurry across to your toolbox to get a ruler. I hope this advice could be of help to you. Keep up the the great videos Kiwi Rodney
soooo...about $1000 in materials and parts and over $10k in tools and equipment to make this and 7 hrs of time, more if you make an error or screw something up and have to restart.
6061 is not the strongest aluminum alloy, there are much stronger choices...but 6061 is the most common structural aluminum alloy and it has the benefit of being weldable if you need to down the road.
