Figure 2 on page 17-06 shows the correct angles to bend the tabs. Another post had a great tip about making little paper triangles to help - that worked great.
There is one shortcoming though, in Figure 2 regarding the bend of the leftmost tab (the 116 degree one.)
Notice how on the right side of that figure, you are shown to "Bend along line tangent to notches for this section." Notice that the 116 degree tab is similarly an odd-shaped tab in that it is not symmetrical like the other tabs. But, there are no special notes about the line to take when bending it.
Well, do NOT bend it along a line drawn like that other guidance! Instead, "pretend" it is a symmetrical tab just like the one next to it (the 82 degree one) and bedn along that theoretical line. The results will be much better.
Good luck!
