Everything in it is a cam converting rotation into rise and fall, or a linkage converting one motion into another. Both are geometry, and both can be drawn before anything is cut.\u003c\/p\u003e\u003ch3\u003eWhat is inside\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThe pinch-point rule that matters more here than anywhere else in the series\u003c\/li\u003e\n\u003cli\u003eThe eccentric cam: why the rise is twice the offset and the motion is smooth for free\u003c\/li\u003e\n\u003cli\u003eAn offset-against-rise table, and the working ceiling on how far you can offset\u003c\/li\u003e\n\u003cli\u003eDrawing a shaped cam from a displacement diagram rather than by eye\u003c\/li\u003e\n\u003cli\u003eSnail, pear and two-lobe profiles, and how follower type changes the drawing\u003c\/li\u003e\n\u003cli\u003eThe Grashof condition — the five-minute check that stops a linkage jamming\u003c\/li\u003e\n\u003cli\u003eCrank-rocker against crank-slider, and which one an automaton usually wants\u003c\/li\u003e\n\u003cli\u003ePivots that survive: clearances, bushing, pin retention, spacing\u003c\/li\u003e\n\u003cli\u003eBoring bearings coaxially, and why crank radius decides the effort\u003c\/li\u003e\n\u003cli\u003eA worked two-cam mechanism, including why phasing them 90° apart makes it look alive\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFormat\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e5 pages, A4, PDF\u003c\/li\u003e\n\u003cli\u003eDelivered as an instant download after purchase\u003c\/li\u003e\n\u003cli\u003ePrint at 100% with scaling off — several drawings are reproduced at true size\u003c\/li\u003e\n\u003cli\u003eNo physical item is shipped\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePlease note\u003c\/h3\u003e\u003cp\u003eThis is a design guide, not legal advice, and it does not substitute for testing.
