Great video! Your calculator is awesome! I’m an apprentice trying to decide if I should make an adaptor or re thread a 4 jaw Chuck for my lathe (Sherline). The Chuck has a M14x1 internal thread, lathe shaft is 3/4”-16 (19.05mm), but the lathe has no threading feature, CAN I USE A TAP TO DO THE THREADING? Will that be precise enough if done in this manner? My simple mind came up with the idea of machining a shaft on the lathe 3 jaw Chuck just to keep concentricity, then attach the 4 jaws one on that shaft, bore the hole, then thread it to 3/4”-16 using the tap. I have no master to teach me and no bigger machine to single point the threads. Any help is super appreciated. Thank you! Edson

Hi Ednos, and thanks for your kind words! Unfortantly, I don't have any experience with re-threading, so I cannot help you with this case. Sorry. Erez
