Saddle
Saddle turns up in 2 fields: electricians, woodworking. Here is what it means to the people in each one.
Saddle in electricians
Set of bends that carries conduit over a pipe or obstruction and back down to its original line.
A saddle lifts a conduit run over an obstruction and returns it to the same line. The common three-point saddle uses a 45-degree center bend over the obstruction and a 22.5-degree bend on each side; the outer marks sit 2.5 inches from the center for every inch of obstruction height, and the center mark moves 3/16 inch forward per inch to allow for shrink. Wider obstructions call for a four-point saddle.
"Two-inch water line across the wall, put a three-point saddle in it, marks at five inches each side of center."
Saddle in woodworking
To cut a curved notch into a log or timber so it fits over a perpendicular piece.
Saddling involves carving a concave, saddle-shaped recess into the bottom of a log or framing member. This allows the piece to drop securely over the rounded top of an intersecting log below it. It is a fundamental technique in log cabin construction and rustic timber framing, relying on gravity and the tight scribed fit to lock the structure together without fasteners.
"Saddle that top log a bit deeper so the wall sits perfectly plumb."
