The mathematics of compound joinery.

   Trigonometric and linear algebraic resolutions are studied. A couple of interesting geometric connections are noted as well.

    ANGLE CALCULATORS contains links to Compound Joinery Calculators that employ vector analysis to determine if a compound joint is possible, and return the basic angles required to create the joint. The Excel worksheet Log Angle Generator may be used to evaluate compound joinery related angles; the instructions give two methods of making entries and interpreting returned values.
