Default Dick Johnson's wing flattening jig?

On Aug 22, 3:04*pm, Walt Connelly

Can any of you tell me if the square of the hypotenuse is really equal
to the sum of the *square of the two adjacent sides or is it just
really, really close?


I so rarely meet right angles that are truly 90.00 degrees, so I
usually use the more general form of c^2=a^2+b^2-2ab*cosC.

I thank you for reminding me of those college math courses with a foreign born prof who had such an accent that I questioned if he was speaking English.

Just wondering if the Dick Johnson wing flattener could be modified to be an SGS 1-34 nose uncrusher, tail straightener, wing undenter and canopy unshatterer?
