Hi folks,

Here are simple calculations.

Not knowing the length of the stabilizer chord, I calculated for 4 chords.
3, 6, 9 and 12 inches.
The dimensions below can easily be interpolated for the actual measured chord of the stabilizer.

First assure that the referencel line is horizonal as practical as you can make it and parallel to the base surface upon which the ruler can sit on (vertical gauge device).

For a 1 (one) degree of incidence ___At left the chord ___ at right the difference between the leading edge and the trailing edge. The leading edge higher for positive incidence. All dimensions are inches.

3 ...... 0.0524
6 ...... 0.1047
9 ...... 0.1571
12 .... 0.2095

For a 2 1/2 (two and one half) degrees

3 ...... 0.1310
6 ...... 0.2620
9 ...... 0.3930
12 .... 0.5239

Above dimensions can be converted to sixty-fourth by multiplying them by 64
Example: 2 1/2 deg incidence and a 9" chord becomes0.3930 x 64 = 25.15 / 64 (use 25)
same in 32nd becomes 0.3930 x 32 = 12.58 (use 12 1/2 / 32nd).

Your accuracy is determined by the ruler reading. It is not difficult to even read 1/128 of an inch using a good steel ruler.
