Zero clearance insert

I built a zero clearance insert two pieces of MDF 10 mm. As the first operation I shaped part superione rounding the corners, so I prepared the lower part.
In the upper part I played 4 holes with a flaring tip, to be able to fix it with screws to the plane of the saw. With the router table I made 4 holes 10mm, which I entered with a bit of glue hardwood plugs.
After inserting the plugs, I always drilled with table router with a 4 mm drill bit. Then I enlarged the holes with drill press with a drill bit 4.5 mm. I finally made ​​the M6 thread, I have the similar marker 4 adjustment screws
serving to bring the level up tablesaw insert. I joined with glue the upper part with the lower one. Then with the router table I had to make a groove at the bottom to be able to start the blade free from obstructions. The work came
  fine.
