Have been out of the shop for a few days due to travel. Thankfully I remembered to pack a few parts to an intricate project which requires some CNC machining. So I fired up my go-to CAD application and started work on the drawings. I was able to make a good start on the 3D model, and will finish the parts this week. Using 3D drawings for replicas can be useful when you might need to change the design. In my case I have gears which need to mate together perfectly. Depending on their position in the final prop I may need to adjust them.
