Work avoidance tactics. Doodling more metalwork. This time a pulley from a book published in 1887.
That is a very nice and precise model. I like the shading and the cutaway view that makes it a very technical model.
Nice model indeed. I wonder how the actual pulley was fabricated? Sand cast? How to expel the pattern material from the annular void that surrounds the hub? There is a channel from the void to the hub, but it seems tricky to empty sand from the void after casting (maybe the pattern was made of wax and melted out).
