Cut my first change gear today. I haven't broached it yet. I'm going to do that after I've made all the gears I need.

Looks very nice, I have been thinking about how to make those since I first got hold of my lathe.

Nice work, out of curiosity did you cut the depth in one shot with a slow feed or make more than one cut to get the depth ?

For mine I did mine in two cuts at the same speed just so I would not screw it up. Ray

I used one cut with a slow feed.

That is a very neat gear.
I would be interested in seeing your broaching process.

Dean has a nice web site showing various projects he's done with his mini lathe and mill. I'd recommend everyone check it out at http://www.deansphotographica.com/machining/projects/projects.html

Nice work cutting the new gear! Where did you obtain the involute cutter? What part number is it? I'd like to cut some of my own gears.

Thanks!
 
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.
