That looks good. I am currently doing the same on my RV-7. From the pictures it looks like some attachment points are recessed. They look like micro cupcake forms. What is the purpose for those? Did you make them yourself ?
I made the offset washers from the soft .010 SS, with a simple press die with a center alignment pin. The pictures pretty well explains the process. I squeeze the die in a bench vise to form the washer. I used 1/8” Fiberfrax and I knew I would get a lot of pillowing if I didn’t do something like this. I glued the frax to the .010” SS with water diluted Elmer’s glue sprayed on with a pump bottle.
