USING THE RISE AND RUN SCALE AND MICRODIAL (OPTION 2) 3. To set the jig for the 1/8” inch divisions (1/8”, 3/8”, 5/8”, 7⁄8”), Another way tapers are often specified is by rise and run (a certain align the pointer near the black amount of taper over a specified length). Your MICRODIAL Tapering Jig numbers with the appropriate black also includes a scale for this. This COLORMATCH rise and run dial and line on the scale.
WORKING TO A LINE CALIBRATING THE SCALES AND MICRODIALS (OPTION 3) Your MICRODIAL Tapering Jig is factory calibrated and ready to go. In Sometimes it is easier to simply layout the taper on your workpiece and the unlikely event that the MICRODIAL scales are not aligned properly, then cut to that line. To set your MICRODIAL Tapering Jig to cut to a line, follow these steps to recalibrate the jig to make the scales accurate lay out the taper on the face of your workpiece.

This means the leg will be After you make the first cut, you have changed the reference surface for thinner after you rotate it to get the second cut.
FOUR AND EIGHT-SIDED TAPERED LEGS 3. For eight-sided tapers, taper all 4 sides of the leg then tilt the saw blade to 45-degrees and reset the jig to the desired rise and run or degree. Making a piece with a four-sided taper is little different than making one Notice the bigger the angle will result with a two-sided taper.
