knee brace layout using long points
knee braces are an important part of traditional timber framing. they work primarily in compression, with opposing braces resisting lateral loads in opposite directions. traditional brace joinery provides relatively little resistance in tension.
at star hill, we lay out knee braces by establishing the long point at each end first. those are our critical reference points because they determine where the brace actually sits in the frame.
for example, with a 30-by-30-inch brace and half-inch-deep housings, our long-point-to-long-point measurement is 3 feet 7 1/8 inches.
we locate those two points 3/8 inch in from the edge of the brace timber. that gives us a nominal half-inch nose using 45-degree geometry.
we'll often use a story stick to transfer the long-point dimension, especially when cutting multiple braces.
once those two points are established, the rest of the layout is developed with 45-degree lines. you can do the entire layout with a framing square, combination square, or speed square.
there are other ways to approach knee-brace layout, but this is the method we use in our shop.
curious how others here approach brace layout. do you work from the long points, or use a different reference?
