Atlas 10F Lathe - TH54 - 28 - Thread Gear Treatise

In this video, I try to answer a viewer, Ben from Ben's Workshop, question about the Atlas 10 Thread gear and thread indicator dial. He is wanting to make a replacement gear and dial for his Atlas lathe. While I provide the information He specifically asked for I also include the calculations to derive the gear with no known information. I hope you find it helpful.
