My Wooden Gears

[fall22123]

Now all you need is a use for wooden gears. They look cool, though.

[elanonimazo2]

Can you tell me the useless of non circular gears?

[steveg769]

@elanonimazo2 - Practical uses for the elliptical gears include certain kinds of pumps, flow meters, and presses. The torque needed to turn a pair of elliptical gears under a constant load varies as a function of rotation angle whereas circular gears would require a constant torque. Other shapes can be made as well - probably more for fun than a practical purpose.

[elanonimazo2]

@steveg769 thanks

[dxpeo]

Neat!

[oscar7363]

were do i go to find out how to cut them

[steveg769]

@oscar7363 - There is a link to my web site in the description.

[kennnmoran]

I doubt if a generator wood conduct electricity that well, unless it was Iron Bark perhaps

[steveg769]

@kennnmoran - I agree :) Lousy conductor. Not very magnetic either - not even ironwood.

[woodentoolcompany]

Awesome!

[magprob]

Those are sweet! You take the term "Gear Head" to a whole new level. I make gears for my Screw Advance Box Joint Jig, found here on You Tube. It's very satisfying to make them and watch them work.

[carlsetzer]

1:36 Holy crap! Keep fingers, neck ties, and cats with long tails away from that thing!

Kinda cool contraption.

[punjedi]

Awesome skills and craftmanship!

[odmcarp]

i have to ask.....why wood gears? do you use them for something, or is this just something you have fun making and enjoy?

[steveg769]

@odmcarp I enjoy the challenge of figuring out how to make them. They do have some uses that are practical such as my window blinds (shown in another one of my videos). They are fun to make and nicer to look at and listen to than plastic or metal in my opinion. They have their limitations of course. And in case you didn't notice, I sell an ebook that shows you how to make your own.

[checkzack]

have you considered attaching a generator or flywheel to the speed multiplier?

[steveg769]

That has crossed my mind before, but you couldn't make much electricity cranking it with one arm. That would be an interesting project though. I have seen generators attached to stationary bicycles - probably the most efficient way to convert man power into electricity. those could probably generate a few hundred watts continuous with a healthy person pedaling. Such a generator would be the ideal power supply for a TV  :-)

[gandreou]

You just reminded me of a scene from the movie Soylent Green. ;-)

[nashkrywka]

whats the gearing ratio of that last gear box?

[steveg769]

Each stage triples the speed, so 1 turn of the crank x 3 x 3 x 3 x 3 = 81 turns on the output. So the ratio is 1/81 or 0.0123456.

[nashkrywka]

very cool, thanks

[bestamerica]

did put ball bearing on this wooden gear

[steveg769]

No, it is a bronze bushing.

[steveg769]

Thanks for the reminder. I reduced the price to $24.99

[shaneomacmcgee]

Very cool. For elliptical gears, do you need specific sizes of gears? A specific major axis:minor axis ratio, perhaps?

[steveg769]

Thanks! I don't think they have to be any particular aspect ratio. I have seen pictures / videos of elliptical gears with different ratios that were even more out of round than these. I have also seen some that had axles through their focus instead of through the center. The timing has to be just right, and the pitch perimeters equal to avoid binding. Or you can cheat and let one gear have a floating axle. All the gears shown here have fixed axles though.

[dandrums04]

cool. you could use it as a crank start when you build your first turboshaft engine.

[jisimon]

Nice job. did you know that that double pinion was invented by Andre Citroen, and he used the picture of the track of the theeth to make the Citroen logo?

[steveg769]

Thank you. The "double pinion" is also called a chevron or herringbone gear. They can handle more load than regular spur gears and are said to be less noisy. I have read about them online. The ones I have made are simply two helical gears one left and one right hand put together face to face. These are as strong as helical gears, but without the end thrust on the shaft.

[1spoonand2forks]

so...you made a set of gears from wood...now what do you do with em?

[ucrash2]

use them to cast metal ones, or to test fit before production.

[manning2g09]

I want a wooden 5 speed tranny for a 98 mitsu how much? maybe you can build it better than mitsubishi did, with wood. Just kiddin cool stuff.

[zagyex]

hi. these are really great. the last two pieces are amazing. thanks for sharing. never seen ellyptical gears

[customlevers09]

very intresting and great wood working.Keep up the good work.

[nateobee]

very cool. but how do you do it? like the title says 'making' where is the making part?

[steveg769]

You're right - this shows nothing about how they are made, so I changed the title.

[nateobee]

that's cool, but how do you do it?

[cedartowndawg]

That is too cool

[imcrazyforspore]

:59 is so trippy

[42fba]

Love the elliptical gears! And you made great use of annotations.

[garoad2]

That is @#$%ing cool!

[ncrailfan]

that is cool.

[steveg769]

Thanks! Sorry to hear you got sick and unable to work with wood. I've never done any cnc routing, but if it enables you to do what you love then go for it!

[scar781ny]

very nice work. always wanted to play with gears but since i became sick in august i haven't been able to work with wood besides modifying a couple rifle stocks. soon i will be getting a samall cnc router. i know it's cheating however i don't realy have a choice if i want to continue woodworking.

[RyanSethDuncan]

Your oval gears are amazing.

[maxpolaris99]

cool you could probably rig it up to start fire!

HaHaHa Fire Marshall Bill signing out

[roodkhooneh]

grate job,

[OlympicClassDandy]

Impressive device! And 8000 RPM? That's excellent; truly a well-engineering gear box.

Great job!

[MrMusicDreaming]

This is pretty amazing, I enjoy the elliptical gears one.

[3icarus]

Very nice. Do you make all your gears on the table saw. If so what is the jig? Regards Martin Cross

[lastquest]

REALLY COOL...Nice Craftsmanship

[steveg769]

I haven't done any miter gears yet, but think it's possible. Internal gears also have me thinking.

[yusufer5000]

thats pretty amazing. do you ever do miter gears?

[BlackRainGraffiti]

Very cool. I never seen gears like that before. I always thought and probably most other people would have thought. That gears would have to be a perfect circle. But watching this just shows that i am wrong and anyone else who though the same are wrong. Amazing piece of work and also inspiring to try different things with these gears. 5 Stars, very interesting video.

[greatspacegibbon]

Those eliptical gears seriously mess with my brain. Nice work!

[far112233]

cool,super cool

[jtodd2008]

Cool!

[steveg769]

Thanks!  I'm glad you think so.
