I recently bought a wm210v extended 8x31 Chinese lathe. They said it would cut imperial threads but the chart is useless. I want to single point 16tpi and don’t understand how to arrange the gears to get the 16tpi. The spindle has 56t and the lead screw is 2mm. The banjo has 3 pairs of gears. The top and middle pairs are gears and the bottom is a gear and a spacer. The top pair of gears on the banjo meshes to the spindle and the bottom gear turns the lead screw. I have the following gears 30,40,45,50,56,60,66,80,80, and 84. I tried the little machine shops gear program but it only shows 4 gears. I’m totally lost at this point and was hoping someone might be able to help me out with this.
