Woodworking
Mortise and Tenon Calculator
Calculates tenon thickness as two-thirds of the rail thickness, rounded to the nearest 1/16 inch — the classic rule for strong mortise-and-tenon joints. Use it when laying out frame-and-panel furniture or door construction.

Woodworking
Miter and Bevel Cut Calculator
Computes the exact miter and bevel angles for picture frames, polygon frames, and crown molding joints. Use it before setting your miter saw to avoid costly cut errors on expensive molding stock.
