View Full Version : When to repair a prop?

Here's the 411:

Stock 26P Bravos. One is "scuffed" or roughed up on the tip of all 4 blades. Don't remember hitting anything, but must have. Not ready to lab the props yet, as I still have to do a few things to the engines/exhaust that should influence the lab work. May be a year before that happens. Currently don't run over 5000 rpm on TRS drives

1. What damage will running the prop in it's current condition cause?
2. If it needs to be fixed now, can it be smoothed down (resulting in slightly smaller diameter) or should it have extra SS welded back on to keep the original diameter? The other drive's prop is still fine and is also stock.

thanks.

Hi,

Sorry for being missing in action lately. The work load this time of year is rather large.

Propeller damage should be repaired as soon as possible. I know that sounds normal coming from a propeller sales and repair person. The reason however is that the leading edge damage sets up stress risers that can cause the flexing of the blades to concentrate at the wounds which eventually will crack. Clean the marks as best as you can with a file and sand paper for now.

Never remove material from a propeller to repair damage. Change the geometry for a performance enhancement only. We always weld on new material and then reform to the original template.
