Four Windings

Five pencil pages signed 'Meyer 1987': the VIC's four windings on one core, the turns, the ohms and the volts worked out in his own hand, and the tapered pin of the injector. Every line of his arithmetic checked, and what each number was for.

What was shown

Five pages in pencil, each signed "Meyer 1987" and numbered "Page N of 5", reached the archive as photographs: circulated on Facebook in July 2022 and posted to the archive's Discord by a member on 18 August 2024. They are the arithmetic behind the VIC memos, which carry the conclusions ("typically 11.6 KΩ", "typically 5,000 volts", "60 micro ohms per centimeter") but not the working. This film reads the five pages line by line, checks each line against the archive's own figures and against the estate transformer Don Gabel measured in 2009, and answers from the numbers why the coil is built the way it is. The pages themselves are reproduced, with the arithmetic transcribed, at Five pencil pages, 1987.

About the voice. Where you hear Stan Meyer in this film, you are hearing a synthetic voice built by a machine from thirty seconds of his voice on the Deer Creek conference tape of 1985. It reads thirteen lines, each his own words and each cited below; most are lines of arithmetic in his own hand, read as he wrote them. The narrator is a stock voice and nobody in particular. Treat both as a reading, not a recording.

What is assumed. Copper at 1.72 µΩ·cm and 430 stainless at 60 µΩ·cm; Wheeler's 1928 formula as he wrote it, on his own dimensions, with a mean radius of 0.96 in for the secondary and 0.84 in for the chokes; Gabel's factor of 16 for the core; the injector pin as a coaxial capacitor in water (εr 78.5) about 500 pF at a .010 gap; the patent's coaxial cell at 2,029 pF from episode 14; Gabel's tube at 21 nF. Every number on screen scales with those choices, and the script that drew the charts is in the repository beside this film.

The four windings

One core carries a primary (200 turns of .028 in copper, 12 V at 1.5 A, gated pulses), a secondary (84,500 turns of .002 in copper in thirteen cavities, 26,000 ft, 67,340 Ω, 5,070 V by turns ratio) and two chokes wound bifilar from one 3,250-turn winding of .0047 in 430 stainless (1,625 turns, 715 ft and 11,655 Ω each), one on each side of the cell. The rule under all four is the note on page 1: matrix circuit allows "electron bounce" while inhibiting current flow. The cell is a capacitor; the source is built to make volts and refuse amps.

The pages, checked

Page 2, the secondary. 2,590 Ω per 1,000 ft is exact for .002 in copper (2,587 by the archive's figure); 26,000 ft is 67,340 Ω; page 1's "62.3 kΩ" is the same wire at twelve cavities (24,000 ft). Two numbers do not close with each other: 6,500 turns a cavity is a bare-wire pitch (enamelled #43 gives about 4,800, 63,000 a spool), and 2,000 ft a cavity implies a mean turn diameter of 1.18 in against the 1.85 in bobbin drawn. What 67 kΩ buys is a ceiling of 75 mA at 5,070 V into a dead short. The formula on the page is Wheeler's 1928 approximation with its inch units; on his own windings it gives 93 H for the secondary, 55 mH for a choke and 0.93 mH for the primary, in air. Thirteen cavities put the turn-to-turn capacitance he names Cd in series rather than in parallel, about a thirteenth of it; a 93 H coil with 50 pF rings at 2.3 kHz in air and under 600 Hz on a core, in his working band, which is why the pies.

Page 3, the primary and the chokes. 71 turns a layer of .028 in a 2.00 × .100 cavity, three layers, 213; 200 used; 84,500 ÷ 200 = 422.5 × 12 V = 5,070 V; 80 ft of wire. The core tolerates it easily: 200 turns at 12 V on a 1 cm² grain-oriented leg is about 135 mT at 1 kHz. The chokes: 25 × 10 = 250 turns a cavity, 3,250 a spool, halved for the bifilar to 1,625 each; 110 ft a cavity, 715 ft a choke; 16.3 Ω/ft → 11,655 Ω, the memo's "typically 11.6 KΩ". And 1,625 ÷ 200 × 12 = 97.5 V: each choke, as a winding on the core, picks up 97.5 V from the primary. 5,070 + 97.5 + 97.5 = 5,265 V, which is page 1's "5,200 volts applied". The injector memo's "Plus Factor" paragraph says the same in prose: the induced field across the choke increases voltage intensity still further rather than diminishes peak voltage potential due to resistive value of the stainless steel wire.

Page 4, the resistivity. 60 µΩ·cm → 60 × 10⁻⁸ Ω·m → 2.3622 × 10⁻⁵ Ω·in; radius 2.35/1000 in, area 22/7 × r²; 1.360994 Ω per inch; 16.331932 Ω per foot. Correct to every figure (the archive, with π, gets 16.34). The memo prints the resistivity with the wrong unit; the page shows he used the right one.

Page 5, the tapered pin. Positive surface .156 in, negative .080 in, .993 in of taper, .010 to .015 in water gap, 5,200 V. Circumferences .489 and .251, ratio 1.948; 5,200 × 1.948 = 10,129.6 "volts". The ratio is the ratio of the radii, and for a pin inside a bore whose gap shrinks with the pin the field at the pin surface does rise by that ratio toward the narrow end; for a gap held at .010 the field along the taper is flat within 5 %; for a gap closing from .015 to .010 it rises by about 1.5. What rises is the field, not the voltage. 5,200 V across .010 in is 520 kV/in (20 MV/m); the pin at that gap is about 500 pF; with the chokes at about 0.9 H on the core the loop lands near 5 kHz, inside his band.

Why it is built this way

Volts from turns (422.5 × 12). Amps refused by ohms, twice (67 kΩ, then 2 × 11.7 kΩ: 56 mA at most). Chokes matched by the bifilar (1,625 each from one winding). Chokes paid back by the core (97.5 V each: the 5,200). Frequency set by the chokes and the cell (0.9 H and 500 pF: 5 kHz; 2,029 pF: 2.7 kHz; 21 nF: 830 Hz). Cd cut by the pies. The stainless is the memos' own reason, in ohms: the resistance damps the loop, a damped loop does not overshoot into the gap, and the gap came down from .060 to .010; the cost, priced in episode 19, is a Q near one.

Two VICs

The 1987 pages wind a 422 : 1 stainless-choke VIC. The estate unit Gabel measured is 29 gauge copper throughout, chokes of 77 and 70 Ω, and a step-up of about 5 : 1 from the ratio of its inductances on the core. The one number the two share is the chokes' inductance: 55 mH by Wheeler on the pages, 76 and 64 mH loose on the bench; about 0.9 H on the core by his numbers, 1.22 and 1.09 H by Gabel's meter. The chokes are sized to the cell, not to the wire.

The sense of the bifilar (aiding or opposing); the gap profile of the pin (constant, closing, or proportional); and which of 2,000 ft or 1.85 in is the slip on page 2. All three are measurements.
