My Wooden Gears

Here are some samples of gears you can make using my technique. I have kept this to myself for a few years while learning more about it, but decided to sell the technique to educate others on how to do this and make some extra money. The technique enables you to make any of the gears of the type shown in this video by using either a scrollsaw or a tablesaw. You can make straight-tooth or helical gears with ease. If you purchase the technique, I will include an Excel spreadsheet calculator that calculates all the needed dimensions using these input parameters: number of teeth, diametral pitch, pressure angle, and helix angle if you want helical gears. I will also include a guide for elliptical gears as seen in this video.

There are no paper patterns to glue to wood and saw around, the correct involute tooth profile is automatically generated. This technique is very simple once you see how it works. There is no need for expensive cnc routers or lasers or any computer-controlled tools. If you have a scrollsaw or tablesaw, the ability to cut accurately sized circles from plywood, and a computer - then you can do this. You won't find this technique anywhere else, I have looked thoroughly and know it is my own original idea. The price is $24.99.

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.

were do i go to find out how to cut them

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

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.

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

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

@steveg769 thanks

Neat!

Awesome!
