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!!

Love it, the use of gears and chains for reversing direction is simplicity itself.

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.

[@larryalexander4833]

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

what is a gearbox pls man help

[@dieselrotor]

Screw run out ! You need some vibration or the chains won't stretch and You'll never know when to pull a link or get a new chain ! What a fun time in the shop. Sweet.

[@Mad-Duk_Machine_Werkes]

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-

It's going to be in a box full of oil.

@@carabela125 So is every other trans. Better than without, though. Excited to see how it holds up

[@nickkaarslev290]

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

[@Mad-Duk_Machine_Werkes]

@@nickkaarslev290 His other ones (like all his Buggies) are built for KZbin 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

[@Mad-Duk_Machine_Werkes]

@@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-

[@blackbartbartholomew7122]

Best music ever for a montage, relaxing. Great Work!

[@jackrichards1863]

Looks like our skilled producer & engineer may have bottled this series for unknown reasons . It's still 3 speed & reverse box finished The addition of grooves on the outsides of the dogs for selectors and some spring loaded detents will have it shiftable . Completeing the case will allow oil bath lubrication. But seeing it done was the exercise really. There are so many used car gearboxes about something the right size w. 5spd & reverse must be easy to retrofit ? Great job "..B welding" . I enjoyed the story. And 10,000 others too. 0.8% of viewers ticked a different tune which is outstanding approval.

[@Crewsy]

The larger sintered metal gear will likely need bushing made for it where the bolts go through the larger holes. The gear will slip back and forth with it only being pinched between the 2 plates that are bolted together.

[@ricerneon399]

I watch your videos at 0.25 speed. It prolongs my happiness 👍

[@EricFixalot]

Looks like you made a dog box from scratch, right on! All it needs is some shift forks and you're good to go.

[@EricFixalot]

Also, I wonder how well a lovejoy coupling without the rubber inserts would have worked.

[@noahsmith386]

Great job. My advice though, definitely make a metal case so that all those gears can be submerged in an oil bath, otherwise all that work will quickly destroy itself at RPM. You also would need a thin oil for the chains and thick for the gears, something like a 0-50 weight oil

[@jadz684z]

Wedges between those dog box gears and a spring to pull them toghter on the side that wont get in the way of( like the back side) so it's always under tension unless a wedge pushes on it

[@francistheodorecatte]

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... 😺

[@shelby5886]

Kinda what I was thinking

[@johnwalker7592]

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.

[@Azlehria]

@@johnwalker7592 Off the shelf parts are easier to replace than custom.

[@hepburn118]

@@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

[@DjRjSolarStar]

Awesome work man. I also have a G0704. One suggestion though - that drill chuck that comes with it is awful. It has around .010" of runout. I highly suggest getting something like a RoHM Supra series, or a Shars keyless integral chuck. Both get around .002" of runout.

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

[@willwade1101]

Synchronizing your shifts will be hard with that set up that's why I suggested using a modified auto trans with built in synchronizers. At least take one apart and see how it it made and see if you can adapt some of the tech in it to your design.

[@AnalogDude_]

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.
