The jig was designed in Shapr3D and sliced using Cura 5.2.1. Its purpose is to hold a dial or digital indicator gauge that has a mounting bracket on the rear housing.
Parts were printed in yellow and black PLA using a 0.4mm nozzle. Other parameters include: 0.2mm layer height, 0.4mm line width, 1.6mm wall thickness, and 25% infill. None of the parts required the use of supports to print but I did add a 20mm brim to avoid elephant-footing.
Additional hardware requirements are an M6-1.0x25mm hex bolt which presses into the bottom of the miter bar, an M6-1.0x25mm flange bolt for attaching the indicator gauge, and two M6-1.0 nuts. One of the nuts is pressed in place into the knob, the other is pressed into place on the crossbar, for holding the indicator gauge.
The miter bar will fit any ¾" (19.25mm) wide, ½" (12.7mm) deep miter slot. It is only 10mm thick to avoid hitting the bottom of the slot. My printer is well-tuned and the bar was very tight after trimming off the brim. Very light sanding with 220 grit sandpaper allowed the bar to slide smoothly with no slop. The same goes for the cross bar that slides over the miter bar and is held in place with the knob.
The idea is as follows. With the jig resting in the miter slot, you adjust the cross bar until the tip of the indicator presses against one end of the saw blade. It should indent just a bit. You take a marker and mark the point on the blade where the tip of the indicator touches it. Next you zero out the indicator reading and then slide it along the blade to the other end of the slot. At the same time, you rotate the blade so that at the other end, the tip touches the same part of the blade. This is so you remove any offset that an out-of-true arbor might have on the measurement process. My blade was off by 0.005" over a distance of about 9". I therefore loosened the table top bolts and aligned it with subtle taps with a rubber mallet until the indicator showed zero deflection on repeated measurements. The indicator is accurate to 0.001", so this meant I'm off by no more than a thousandths of an inch over the distance of the blade. Finally, you can use the jig to ensure that your rip fence is parallel to the same miter slot in the same fashion, and this ensures your fence is also parallel to the blade.
