[rotorwrench]

I remember reading all the wood spar repair details that were published by Parson's for their wood main rotor blades back in the day. While removing bad sections and gluing in good replacement wood patches was successful, it was also a lot of work too. There was a good reason to repair the expensive blades. When considering replacement of smaller wood pieces that are basically support for the roof and body structural rigidity, a person has to weigh the benefits of such work against the benefits of replacement of the member depending on which is more practical. A person can just replace the damaged members. With wood, there is a lot of flexibility in repair and replacement methods since a well fit and glued joint is every bit as strong as one with no repairs or splices if the job is done correctly.
