I found a really cool application for the Scrollmania angle calculator. I had a project were I needed to drill some 6 degree holes. I went to the angle calculator and entered a thickness of 1 and a width 0 and solved for the angle. If the angle was less than 6 degrees I increased the thickness by 1 and solved for the angle. If the angle was less than 6 degrees I increased the thickness by 1 and solved for the angle. I kept doing this until the angle got close enough to 6 degrees.

1 0 0.0 (increase width)
1 1 45.0 (increase length)
2 1 26.6 (increase length)
3 1 18.4 (increase length)
4 1 14.0 (increase length)
5 1 11.3 (increase length)
6 1 9.5 (increase length)
7 1 8.1 (increase length)
8 1 7.1 (increase length)
9 1 6.3 (increase length)
10 1 5.70 (increase width)
10 2 11.3 (increase length)
11 2 10.3 (increase length)
12 2 9.5 (increase length)
13 2 8.7 (increase length)
14 2 8.1 (increase length)
15 2 7.6 (increase length)
16 2 7.1 (increase length)
17 2 6.7 (increase length)
18 2 6.3 (increase length)
19 2 6.0 (DONE!)
So I took a piece of scrap wood and cut a triangle that was 8.5 inches (19/2) long and 1 inch (2/1) high and cut it out on the scroll saw. I now have a 6 degree reference guide.
This will work for whatever angle you wish.
