Hi all...
Have just started riveting the ribs to the main spar (RV-8). I noticed on the Fore side of the spar where the shop head is being formed, very tiny "fan/hairline stress marks in the anodized finish of the spar. Is this a normal result of the force from the process, or am I doing something wrong. The spar is reasonalbly secured, and the psi is set at 45 (4-5 rivet). Thanks
