Step 2: Disassemble Angle Divisor Tool
Start by removing the rivet connecting the three aluminum bars at the end of angle divisor (far right in the main photo). Tip: Grind off the backside of the rivet using a grinder or Dremel tool with grinding wheel bit, then remove the rest of rivet with pliers.
Remove the adjustable thumbscrew and keep the slotted bar and shinny rectangular guide piece (bottom of the second photo) – discard the rest of the angle divisor. Use a ¼” drill bit to enlarge the hole in the shinny rectangular guide piece. The hole is very close to ¼” already, but still needs to be enlarged.
