have updated my method
for making wooden gears to make it better.
The new E-book contains 52 pages, and lots of illustrations to cover the
technique using table saw, scroll saw, and
now the router. This PDF file will most definitely save you a lot of
and frustration over the other method of
sawing and sanding around a pattern. It describes how to make spur
gears, helical gears, and gear racks. It is
easy to get good and consistent results. If you have specific questions
about it, then send me an email firstname.lastname@example.org.

The Gear making technique is available as an instant download ebook PDF file by clicking the button below. By clicking this button, you will be taken to Paypal to confirm. You will then be sent instructions to download the files. If you do not have a Paypal account you can still use a credit card for the purchase through Paypal. If you do not have or want to use a credit card I will also accept money orders - email me for mailing address. The price for the technique is $24.99
How Does It Work?
The technique utilizes a simple principle of a point along an unwinding string illustrated above to generate gear teeth instead of sawing or sanding to a line on a paper pattern using the old method. This makes the task of cutting gears much easier, less tiring, and more accurate than other methods, it also lets you make helical gears which are not possible with the old method. You can make gears with any number of teeth . Chances are that you already have all the tools you will need: drill press, bench-top disc sander, and either a tablesaw, scroll saw with spiral blade (spiral blades are not available for saws requiring pin-end blades), or router (spur gears only with router). You can use ordinary table saw blades or straight router bits. The simplicity of the technique is what makes it work so good. The only sanding you will need to do is to lightly de-burr the edges after the teeth are cut or shaved to perfection. You will get a perfect profile even if your vision is not very good because the cut does not rely on cutting to a line visually, the profile is generated as shown in the drawing above. Small gears are not a problem to cut safely because they are not held by your fingers while being cut. Very little of the blade is exposed and I believe this technique is safer than making a rip cut on a table saw.
When 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. This spreadsheet can be used with Google Documents (free with Google account) if you do not have Excel. I will also include a guide for elliptical gears as seen in the video. You will also get future updates at no charge as I make improvements and add new capabilities, technical support, and sample guides (pdf format). You will also get access to my videos that demonstrate the technique in action on router, table saw and scroll saw.
