Tricks Of The Trade – Bisecting Odd Angles

The easy way to find odd angles

.

Here's a trick you don't come across too often

But boy is it handy and accurate.

You could take you bevel gauge and get the larger angle and then take a compass and bisect the angle like you probably were taught in math class way back when.

But there's a better way.

Watch this short video to discover this great trick.

    In the real world.. Three 90s make a circle. Just look up at your corner and ceiling if you don’t believe me. Have a great day. Merry kissmyass!!!

    My way is using any piece of paper…….. fold it so that it matches the angle and then fold it in half again……….. use that pattern to set the saw. Easy, cheap, and fast!!!

    Law of Cosines to find exact angle
    Divide by Two & set saw!
    PS: Sum of exterior angles is 360°
    Divide number of segments into
    180° to find the half angle

    Slick enough, but… the angle that you determine, with this method, is also dependent upon another factor which Tom neglects (or is unaware of), namely that the two scrap pieces (of identically dimension) must be held perpendicular to the intersection of the wall surfaces, in most cases that would be horizontal. He illustrates this by using the demonstration “floor,” yet makes no mention of how this may or may not influence the accuracy of his measured angle. And especially in a little old house, even the floors are not always horizontal…..

    Don’t know bout y’all these hands are skilled. Ryobi battery skill. Speed square pencil. Trim nails and an east wing baseboard quarter round. Crown molding and these hands. Done in no time

    It would be an illusion if your house isnt square. And you can cope an outside corner, i prefer just to back cut it. There is all different ways to do it, as long you end with the same result, whats the difference?

  7. Thomas Stone said:

    Yes, we get it; some people prefer to use a coping saw. But that method doesn’t teach or hone your trig skills. And any carpenter will tell you their most important tool is math. Second is a sharp pencil.
