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.

More in projects, start to finish
Whole project · 8:36A carriage that shuttles between two limit switches: the whole project
A rack-and-pinion carriage and its control logic, built from a blank drawing in six steps. The drawing side is rectangles, the Gear tool, a rack added to the gear by a right-click, and an assembly. The Motion window gives it a slide and a motor; the Controls section adds two limit switches, a counter, two buttons and a gate, and five rules that read as plain sentences; the control panel runs it. It shows a machine's wiring tried out on the drawing before anything is built: what each switch is for, what each rule does, and the log of what happened.
Whole project · 5:04A carved relief: the whole project
A relief carved from a depth picture, start to finish in four chapters. The picture is opened in the picture window, carved as a Relief, shaped with Flat background, Fade the edge, Fullness and Depth, and placed; the CNC job roughs it with an end mill and carves it with a tapered ball nose, with the passes, ridges, depth and run time in plain sight. Shape it brings the picture back to turn the head into a mold, a 3D model is added beside it from an STL file, and the simulator carves the whole job and finds nothing to fix.
Whole project · 7:42A carved shop sign: the whole project
A carved shop sign followed from a blank drawing to a machine. A 600 by 300 mm board is drawn by typing its size; WORKSHOP is set in a carving font round an arc; a border band is made by two offsets; an emblem is traced from a picture. Everything inside the edge is V-carved, with an end mill clearing the flat floors; the outline is cut out last, ramped in, on four tabs placed by hand, starting on the bottom edge. The simulator finds nothing to fix, a job sheet and three programs are written, and the first program is framed, checked, started, paused, resumed and run to its end on a pretend router.
Whole project · 7:09A flip-up cabinet door on a gas strut: the whole project
A wall cabinet's flip-up door, from a blank drawing to the strut to buy and where to screw it. The cabinet is drawn from the side with rectangles and typed sizes; the door is pinned at its hinge with stops and pulled by hand; Check for hits finds the door's back corner binding on the cabinet top and the Clearance tool gives it a 2 mm reveal. A gas strut between two drawn studs is sized by the program (71.6 N holds this 3 kg door level; an 80 N strut is fitted), let go to see the door stay shut and stay open, and its fixing point is tried in a worse place and put back. The last chapter reads off the strut's lengths, saves a film of the swing and dimensions the fixing points.
Whole project · 4:26A photo on wood: the whole project
A photo was engraved on wood and cut out with a frame. The film shows the picture window at its Laser choice, the picture on the drawing shown as it will burn, the ways of burning it (Dither, Newsprint, Threshold, Grayscale), brightness, contrast and line spacing with the run time following, the dots seen close up, a material test made from its numbers, a frame drawn on a Cut layer, and the preview with its clock.
Whole project · 6:56A toggle clamp for a jig: the whole project
A toggle clamp for a jig, from a blank drawing to two working clamps and a plate ready to cut. The four parts are drawn from the side as rectangles and slots with typed sizes and welded where two shapes make one part. Four clicks pin them into a four-bar linkage that is pulled by hand; stops on the link make the lock, and a spring under the pad shows it: short of center the clamp springs open, past center it holds. A fence in the handle's way is found with Check for hits and moved with the Clearance tool, the pad's path is traced, the spindle is stretched for thicker work with its dimension following, and the whole clamp is copied, joints and all, onto a second plate. The plate is drawn from above with mirrored holes and checked for cutting.
