I'm going to make some gears soon and came across this while brushing-up and refreshing my memory. Of course, the Machinist's Handbook has it all but, this is a very nicely authored and to-the-point tutorial. This is based on Diametral Pitch and not the Module method. I have some other guides based on Module method but need to check the copyright information.

Enjoy...

Here's some other decent guides. Very "user-friendly". More discussion about "Module" method of dealing with gears.
BTW: Gears are gears but, SAE terminology tends to do measurement by Diametric Pitch and Metric terminology handles things with "Module" methods.

One can be converted to the other. The analogy I think of, is that SAE measures bolts as Threads-Per-Inch and the metric system handles things as Millimeters-per-Thread.

Hi Ray.
I am also getting into gear cutting soon. I just got myself a Vertex BS-0 dividing head 20180404_090847.jpg

So I am really fresh on gear cutting scene. And in my neck of the woods we mostly work with the metric form but also imperial. So thanks for posting. I am going to go through those.

Ooooo, nice! Nice indeed! You're going to have fun with that!

Do you have a project in mind or, are you just in the process of teaching yourself something new?

I have 2 things in mind... Someone is requesting that I make two replacement gears and he wants them somewhat hardened if possible. He also wants them to operate quieter. It's nice that this side-job came along because I have always wanted to make a project of my own that needs a good bunch of different gears. The project is a gear rack that synchronizes a mill table and a rotary table. I've never made a worm gear and want to see if I can. So... it's "Gear Season" in Ray's shop ...

Gear season indeed Ray.
Yes to both. I want to start with 4 different size gears for my lathe. It has a metric leadscrew,but can do metric and imperial threads,but I want to be able to do a much coarser thread like 1Tpi so I can use it for grease grooving on shafts. So that would be my firts gear project. And also I want to make a thread dial for my lathe. So in short I will be the test subject for learning something new. But you can do so much with a dividing head. I have been wanting one for a long time.

Could you tell where you bought that dividing head

This thread is right on time for me too!! I am working on a milling machine table drive setup using one of the miniature 12v high torque motors to drive. Off the shelf gears that would fit or meet my specs are extremely hard to find and/or expensive to buy.

Thanks for sharing the attachments
