A geared trip hammer, part 1 of 7: The frame and the hammer

A geared trip hammer: the whole project

A geared trip hammer built from a blank drawing in seven steps: a frame and a hammer from rectangles with typed sizes, a cam wheel made with Array and Weld, two pairs of gears placed on the meshing ring, a pin, a motor and a crank with a slide. It shows the ordinary drawing tools and snaps, the Gear tool, layers as heights, assemblies, the Motion window's joints, the gear train's table and ratio, parts pushing each other by touch alone, weight, Check for hits and the Clearance tool, Trace, Slow motion and Save a film. Nothing in the machine is scripted to move: the motor turns one gear and everything else follows from how the parts are drawn.
