Mine are so tight that it is impossible to get them through the rib holes. I've tried gently sanding the outside of one of them (at the cap end, where no glue will be used) and am getting close to having it fit, but I wonder if sanding out the holes isn't a quicker, cheaper way to go?? I worry about overdoing it either way...

Second kit, so next time I'll remember to check it out before starting with the wings. I'm at the stage on the first wing of inserting it for installing the web shears.

I've thought about fine sandpaper around the Al tube as another approach...

Any thoughts?
