Timber Wing inspections

[Peasant_Pilot]

Good evening all,

 

Just looking to get some insight on inspecting wood wings, they are uncovered and mostly constructed, they are either Spruce or Hoop pine but id say they are hoop pine just based off the information i have.

 

besides the obvious things like cracking and splits etc, are there any techniques, checks i can do on the spars? moisture check etc

 

Cheers in advance

 

Cheers

Spruce has nice visible grain, hoop pine much less so.

Post some photos perhaps.

They have been in a shed for years, some bird crap in a couple of spots and a lot of dust
