• Using the paper clips and clamp bar, clamp a piece of paper into the frame.
• Position the top edge of Sliding Guide all the way down to the Zero
  (0) position on the side rulers.
• Draw a line along the top edge of the Sliding Guide, making sure the line is even with the
  Zero position of the rulers
• Draw a vertical line off the Sliding Guide
• Using a protractor, draw a 10° line off center line on each side, start from
  the common point where the vertical and horizontal lines meet.
• Use the angles listed below to create similar graphics for differing numbers of segments …
  • For 18 segments:The cut angle is 10° (18×10=180) off vertical
  • For 15 segments:The cut angle is 12° off vertical
  • For 10 segments:The cut angle is 18° off vertical
  • For 8 segments:The cut angle is 22.5° off vertical

When used, The distance between the right and left 10&#176 lines will be the segment length.

This graphic should be saved. I can be used for all rings with the same number of segments (in this case, 18 segments).

• Use your plan design board to determine segment size.
  1. Put a piece of paper on the board.
  2. Secure the paper to the board with clips and bar.
  3. Draw a horizontal line between zero points on the rulers.
  4. Use a protractor to draw the angle lines appropriate for the number of segments
     that you want in your ring (use the table above that associates segment counts to angles).
  5. Place the sliding guide on the design board.
  6. Assure the horizontal line is even with the 0 marks on the rulers of each side.
  7. Slide the sliding guide to 1/2 the diameter of the ring you desire.
     (Again, if you want a 10″ diameter ring – slide the guide to the 5″ mark
     on the side tape measure.
  8. Use calipers to measure the distance between the two lines
     on the top edge of the sliding guide. (Measure inside of the ‘V’, measuring
     from left and right lines).
  9. Place the calibers against a side tape measure and read the
     separation of the caliper points. Use this measurement when cutting the segment.
• Use the measurment.
  1. Transfer the measurement to a ruler.
  2. Place the rule against the miter gauge and slide the ruler to saw blade.
     For precise ring sizing, measure this length to the furthest tip (right side)
     of the saw blade.
  3. Clamp a piece of wood (to form a measuring block) for duplicate cuts.
  4. Make the first cut (cut off the end to get the starting angle),
     flip the wood to make the second cut.
  5. Place a measuring tape or ruler against the longest length.
     If cut and measured correctly, this distance should match the
     calculated segment length.
  6. For each ring diameter, adjust the block distance relative to the saw blade
     to increase or decrease the segment length to the desired sizing.
  7. Continue cutting the required number of pieces for each ring.
