When we receive your propeller it is tagged with your name and any special instructions for the technicians. Your propeller is assigned a control number to assure that we repair and return the propeller you gave us. Next your propeller is straightened and pitched using a pitch block. A pitch block is a precision machined dye of your propeller, which allows us to correct the pitch, rake and track of prop. Next the prop is glass beaded to remove all paint, corrosion and residue. After your prop is clean it is off to the welding station to weld back any missing blade area. Once welded, the prop is reshaped and excess weld is removed. It is at this point that your propeller is balanced so that it operates smoothly and quietly. As a final step your propeller is primed and painted to protect the metal. Stainless Steel propellers are repaired much the same way except it is polished back to a high mirror finish.
