Gear Cutting with the G3617 and a Dividing Head

I had an old flat belt Logan lathe that had a broken tooth on the saddle feed gear, so I decided to make a new gear. The gear is a double gear; i.e., it has two diameters, one with 32 teeth and one with 16. This series of photos shows me using a gear cutter on the horizontal spindle. The gear blank is mounted on an arbor and indexed by a dividing head.

I took these pictures with my cell phone, so the resolution is not up to the quality one would expect from a real camera.

Almost immediately after finishing this gear, I bought my PM-1640. Needing the space, I had to get rid of the Logan. I loaned it to a friend, so I do not have any photos of installing the gear.

I started with a cast iron blank, turned it to shape on the lathe,
then set it up on the mill, using the dividing head.

Here, I've cut about a quarter of the first gear.
