Cutting an Acute Bevel
Standard circular saws and miter saws can cut bevel angles up to about 54°. While that handles most day-to-day needs, every so often you need to make a cheek cut that a standard saw can’t accommodate. For example, I recently found myself having to cut a 71° bevel on a piece of 2×6 blocking for a set of winding stairs.
The technique is simply to cut the angle on each edge of the board using a circular saw and then to connect the cuts using a reciprocating saw or a handsaw. In fact, you could make the entire cut with either of those tools, but it’s hard to cut accurately with a recip saw, and using a handsaw is tedious.
Working with square-edged lumber is crucial. If the edge isn’t square to the face, your cuts won’t align. Careful layout also is important, because the accuracy of the second layout line depends on aligning it with the first. Likewise, the third line’s accuracy depends on how it intersects the second line. Errors can accumulate rapidly.
