Pro Tips for Blueprint Success

Print the Key Pages

Print the main assembly and wiring diagrams for easy workshop reference. Laminate them to protect from oil and dirt.

Highlight Completed Steps

As you complete each step, highlight it on the printed blueprint. This prevents skipping steps during complex assembly.

Double-Check Measurements

Measure twice, cut once. Small errors in coil dimensions or magnet spacing can significantly affect performance.

Use Videos as Backup

When a diagram is unclear, refer to the video tutorial for that section. The close-up footage often clarifies ambiguous details.

Historical Blueprints & Newspaper Archives

The original 1928 documentation that inspired today's reconstructed blueprints

The modern Hendershot Generator blueprints are reconstructed from historical sources dating back to 1928. While the original blueprints were lost to history, researchers have pieced together the design from period newspaper reports, patent filings, and electromagnetic principles. Here are the authentic historical documents that inform today's construction plans:

February 25, 1928 New York Times - Perpetual Motor Impresses Experts, W.B. Stout verification of Hendershot Generator
Feb 25, 1928

Experts Verified the Original Device

W.B. Stout, head of Stout Air Lines and designer of the Ford Trimotor, called the Hendershot demonstration "impressive" and "uncanny." These eyewitness accounts provide the functional specifications that inform today's blueprints.

1928 newspaper - Perpetual Motor is a Generator, Major Lanphier military confirmation of Hendershot device
Feb 1928

Military Tests Confirmed Power Output

Major Thomas G. Lanphier, Commander at Selfridge Field, stated the device had "enough power to kill a man." Documented tests showed 1,800 RPM sustained for 3,000 hours — the performance benchmarks that the modern blueprints aim to replicate.

Historical note: The original Hendershot blueprints disappeared after Lester Hendershot was hospitalized in March 1928. The modern guide represents a reconstruction based on historical research. Builders should understand that while the electromagnetic principles are sound, exact replication of 1928 performance claims has not been independently verified.
