I'm currently finishing my RV-8A in our EAA museum that is shut down for the winter and there is a guy that owns a plane next to me that noticed the hinge pin covers on the front of my cowl. As many have done, I made up aluminum plates that cover the hinge pin for the cowl split so that they don't wiggle forward into the prop. He asked me if I would do that for his plane. I said that I would give him a quote with estimated hours and an hourly rate. What do you think would be a fair hourly rate for this? Note I'm not an A&P, just your average RV builder.
