How to repair a propeller
Preperation
Grind the damaged part of the blade to remove any sharp edges and paint.
Now brush the damaged area throughly with the stainless steel brush, to break up surface oxide and remove paint.

Heating
Heat the blade hot enough to flow the rod without the aid of the flame.
Tin the flat (not bevelled) side and attach a temporary support of stainless steel or iron. Turn and tin the bevelled side.
|
|
Building the blade
Build out the blade slightly larger than its original size. Leave it to cool naturally. When it cools, the stainless or iron support will simply fall away.
Now grind damaged edges to a 45 bevel. Pitch propeller to standards.
