Here are the finished 7 change gears I was able to make with the #3 cutter.

You used the same cutter for all the different number of teeth?? The cutters I have are only good for lets say 10 to 16 teeth then the next one is 17 to 24 and so on. Ray

Hi Scott,
Nice job on the gears! What type of steel did you use? I just bought a new (used) lathe which I'll pick up tomorrow and I think there may be some gear making in my future.

The #3 cutter will cut 35-54 teeth gears. These 7 gears are 36, 40, 44, 46, 48, 52, and 54.

I used aluminum. Steel may be better but I'll find that out after I use them some. Another member made some out of steel and said they were noisy.

As change gears in the transmission they should do well. I have always been a big fan of using a sacrificial material when I make those kinds of parts because if it gets into a bind with hardened steel or some exotic alloy it could damage some other more expensive part or even one that is not available so I tend to avoid hard metals if I am replacing plastic or delrin types of gears. That way I can limit or prevent damage to other parts of my equipment. I still occasionally turn a hand wheel the wrong way or something similarly stupid so I need all the help I can get...

I got my cutter at Travers. Here is a link to the 24DP 14.5PA cutters. If you do not know, cutters are numbered 1 through 8. The number of teeth on the gear to be cut will determine which cutter to use.

Cutter number Cuts gear from
1 135 teeth to rack
2 55-134
3 35-54
4 26-34
5 21-25
6 17-20
7 14-16
8 12-13

I bought the #3 cutter part number 10-283-240.

Thanks! I archived this list.
