Could some help me with the dimensions of the thread dial indicator gea and its thread pitch. I know I dont need one to cut threads but Im looking for a project to do. I can see that the feed screw is 3/8 pitch but I dont understand what that stands for. Ive searched the web for screw pitches and I cant find anything that resembles a 3/8 pitch to buy a gear for the TDI. I saw on another post that the gear is a 16 tooth but there were no dimensions such as diameter and thickness etc. I found drawings for a 16 tooth 4 pitch that could work but Id really like to understand the 3/8 pitch and make a proper sized gear. Any help would be appreciated. If someone wants the gear dimensions I found I can share them.
Thanks
