Wedge size calculations. - bob-t - 10-11-2017 Attached are two pdf files that I created to show the sizes of a wedge needed to create a ring of rough diameter x. The table allows you to select a diameter for a ring and then reading across the line the sizes needed using different angle wedges. For example a 4" ring could be made using 6- 12 segments, 6 – 24 segment and 9 – 36 segment Cutting at 1.07, .53 and .35 . From the decimal table. The fractional table is a little harder to read, I could not come up with a way to display fractions in a compact manner. So 1 and 1/4 would be represented in the table as 1(16).

Hope this helps. Let me know and I will try again.... Row 5 across shows the arc angle of the cut segments in a ring and down is the diameter of the ring. It is just 360 degrees divided by row 4 ie 360/8 = 45. The way you can cut segments with a wedge sled I found it easier to think of the angles as what part of the circle -- arc angle instead of the normal way you would set the miter gauge to cut each side of the wedge. If you were using a miter gauge to get both sides of the wedge the same you would need to divide this number in half. Bob |
