An experienced propeller repair agency is expected to work with a number of materials varying from place to place. The commonest of materials that most agencies work with every now and then is that of aluminum and composite props for turboprops and aircraft piston engines. The propellers made of aluminum alloy can be repaired effectively and used over again and again with an optimum level of performance. The blades with scratches, scars, dents, pitting and nicks can easily be repaired provided that the repairing does not dampen the performance, strength and weight of the blade. Any surplus metal can easily be cut and removed using fine cut files or sandpaper.
In every similar case, the affected area will first be rubbed with a sandpaper to remove any surplus metal coating from the body of the plate followed by cutting and removing extra metal from its body. The cracks and similar damages are carefully etched. The etching process is done locally to minimize the chances of removing excess metal. After completion of the repairs, the blade is inspected either by anodizing or by chemical etching. The side effects of etching are removed using emery paper. Finally, balancing is done to make sure that the blades retain their overall level of performance. If you are willing to know the need of proper propeller balancing, the primary reasons for which balancing is considered to be prime importance accounts to the facts that balancing is the sole determinant of the manufacturer technical specifications.
A co axial hole is driller at either ends of the blades sometime to obtain a desired level of static horizontal as well as vertical balance.
For vertical balancing, an eccentric hole is drilled within the outer holes drilled for horizontal balancing.
