BRS Installation Hints

Rear Top Angle Brackets

• The manual asks for a 7.5 inch distance between the center of the brackets. That is really not achievable. On the right side, the angle bracket needs to sit further to the right because of the center strut. If you then locate the left angle bracket 7.5 inches apart, the bracket overlaps the J-stiffener completely. A compromise is to overlap the stiffener just a tiny bit so you can still reach the rivet line. It requires filing a bit off the angle bracket to make room for the j-stiffener in the short overlap area. The distance is then around 8.75 inches.
  
• The big round hole of the angle bracket that needs to be match-drilled into the top skin has the size of a 1.5 inch conduit (actual hole size: 1.951 inches). Very easy to do with a hydraulic punch, e.g. at Amazon. Suitable is also just the punch that uses a bolt instead of hydraulics, e.g. at Amazon.
• The two larger 1/4 inch holes that need to be match drilled should be pre-drilled with a smaller diameter drill bit first using the 1/4 inch bushing which comes with the RV-10 kit.
