On your RV14, do those bolts in the weldment at the aft end also capture the bottom of the VS aft spar? They do on my RV6. Maybe you might want to remove the VS some day. I removed mine while assembling the elevators after spending hours trying to get necessary spacers between the elevator horns and that center bearing. It took about 15 minutes to remove the VS and access to that area became wide open. I’m glad those bottom bolts were not installed with loctite. I think a lot of thought has gone into the design/assembly of these kits over the years. But good on you for asking the question. Builders have come up with some good ideas over the years that improve ease of assembly and other things - shared here on this website to the benefit of everyone - sometimes. Asking the question first on this forum usually results in some helpful suggestions. Sometimes it is an oh-s..t moment when we’ll all say, ‘why didn’t I think of that’. Most of those moments have already been breached, but keep trying.
