First, the slope for both the Stave and the Compound angle is the number of degrees from the table where zero is flat on the table and 90 degrees points straight up.

It is important to understand the difference between staves and compounds. A stave is a ripping process that means a stave is typically a tall ring where a long segment is cut from a long piece of wood. A compound is a short ring where the segments are crosscut from a board just like you would do if you were cutting ‘flat’ segments.

Aside from the difference in cutting staves (rip cut) and a compound (cross cut), the calculations for the two types solve for different values.

In a stave, you specify the lower outside diameter, the upper outside diameter and the height of the ring and the software solves for the slope.

In a compound, you specify the slope, the lower outside diameter and the height and the software solves for the upper outside diameter.

Now I’ll link you to a thread that goes into a lot more detail regarding Stave and Compound and when and why to use one or the other. Please be advised, though, that the calculations for the board lengths of the two tilted segment types are the only ones that would work for them. Since staves are ripped from individual boards, the board length is the total length of the boards you need for the number of segments you want.

For the Compound, the formula is similar to a Flat where you are going to flip the board after each cut and the Board Length is how long of a board you need to cut your desired number of segments. Any other calculation could be interesting, but it wouldn‘t be the correct board length.

The main thing you should learn from the following link is how to use the ‘wedge’ technique to cut the time it takes to make a ring of tilted segments in a fraction of the time it takes using the traditional method of tilting your blade to a goofy angle and using a non-standard angle for the fence.

Hello, I am somewhat experienced with V2 of WP. I just upgraded to V3 and I have a few issues. Here are the two that bother me the most. I can't use WP to draw a shape, composed of compound segments, that is wider at the base and converges to a small diameter at the top, for example a...
