Making a Custom Gear

In this video I'm going to make a custom gear for my lathe. This special gear is needed to have additional feed rates to turn threads on the lathe, especially 26tpi. My lathe can cut a ton of different pitches, but not 26tpi. To cut a thread with 26tpi you'd need so called „special accessories“, which is just a special gear with 46 teeth and 52 teeth to replace the standard gear with 21 teeth and 28 teeth. So I decided to make my own. As I don't have any gear cutting milling tools I decided to make the special gear with two welded together normed stock gears. I was able to order them online for $25 each. After welding them together I made the bore to the proper size, turned three grooves and cut a keyway on the arbor press with a 5mm keyway broach. It all worked out as planed.

I hope you like my work and the video.
