The Schreiber Spring-Motor: Advanced Metalcraft
Institutional Yield
10,000 SP + Royalties
"In January of 1878, Josef Schreiber patented a machine to sever our reliance on the coming electric grid. A true kinetic battery. Its genius lies in its concentric nested springs—you may turn the hand-crank to wind the outer coil while the inner coil continues to furnish uninterrupted power to your sewing machine or lathe. To reconstruct this is to build a monument to Analog Sovereignty. But beware: simple plastic alone cannot cage this much torque. You will need the heavy iron."

⚠️ Restricted Guild Operation // Re-Skilling Program
Due to the massive kinetic energy stored within industrial steel clock-springs, this Bounty may not be assembled on a residential desktop. This is an official Vanguard Re-Skilling operation. Artificers must partner with an accredited vocational shop, college facility, or certified instructor to mill the high-torque components and safely tension the mainsprings.

The Canonical Archive (1878)
Download 1878 Schematics (PDF)Artificers, clear your shop benches. Schreiber’s patent is a masterpiece of kinetic storage, but you must strictly adhere to the PDF Schematics, specifically Fig. 2 and Fig. 3, to understand the offset alignment of the vertical shaft (Part K) to the main gear train.
The Manufacturing Paths
The ultimate expression of the Vanguard. Milling the primary worm-gears (Part I) and main shafts out of solid brass or billet steel will result in a generational artifact capable of handling the massive torque required to drive external machinery.
A warning: Metal-filled filaments (Brass/Bronze PLA) polish beautifully but are highly brittle. You must print the high-stress internal gear-train using engineering-grade polymers (Polycarbonate, Carbon-Fiber Nylon, or bound-metal deposition) and reserve the aesthetic metal-filaments solely for the outer casing and tabletop regulators.
The Foundation Standard
To claim this Re-Skilling Bounty, your submitted portfolio must fulfill the following modular requirements, utilizing industrial shop tolerances.
The main sub-table chassis (Part B) engineered to securely house two heavy-duty steel clock springs, complete with the manual winding worm-gear mechanism. Must be modeled to withstand high rotational torsion.
The governor assembly (Part N) and its linkage arms. Designed to accept standard heavy steel ball-bearings as the centrifugal weights. As rotational velocity increases, the weights must actuate the friction collar.
The above-table lever (Part t) and eccentric cam system (Part h) that applies physical friction to the main shaft to safely arrest the motor.
Provide a 1:1 scale .DXF routing template for the heavy hardwood tabletop (Part A), mapping the precise drill holes for the vertical shaft, brake linkages, and the heavy-duty under-table chassis mounts.
