Thrust and camber faces of a propeller should be blended out to
- 5 times the depth of damage.
- 10 times to the depth of damage.
- 30 times to the depth of damage.
Explanation from PART66Online
When dressing out damage on the thrust (rear) and camber (front) faces of a propeller blade, the repair is blended over a length of about 30 times the depth of the damage. This very shallow blend minimises stress concentration on the broad blade faces, which carry the main aerodynamic and bending loads.

It’s 10 when the damage is on the leading and trailing edge
