If you thought using a utility knife manually was such a drag, you’re not alone. [luben111] took some initiative to take the wear and tear off your hands and put it into a custom machine tool they call TOCK, or Tangental Oscillating Cutting Knife. TOCK …read more

Anyone who has ever wound a coil by hand has probably idly wondered “How do they do this with a machine?” at some point in the tedious process. That’s about when your attention wanders and the wire does what physics wants it to do, with the rat’s nest and cursing as a predictable result.
There’s got to be a better way, and [Russ Gries] is on his way to finding it with this proof-of-concept CNC flat coil winder. The video below is a brief overview of what came out of an intensive rapid prototyping session. [Russ] originally thought that moving …read more

Drag Knives seem to be the overshadowed awkward kid on the playground of CNC equipment, but they have a definitive niche making stencils, vinyl stickers, and paper cuts. Unfortunately, the drag knife blades for CNC routers are pricey — over $100 for a single blade. [Brian] at the Grunblau Design Studio took the price point as a challenge to build his own end-effector. A few iterations later, he’s created his very own drag knife blade tool that accepts replaceable steel blades for cutting.
From constraint-driven concept, to a 3D printed proof-of-concept, to a fully machined aluminum prototype, [Brian’s] efforts hit …read more
