I decided to buy the RV-14 baffle kit. And boy am I glad I did. They fit together like a glove and the instructions are unbelievable.
All the holes are pre-drilled to final size. So just debur, cleco and rivet. This saves a bunch of time. If the whole RV-14 kit is like this it will be a dream to build.
Left side of the baffles. Still plenty of meat to attach the baffle material.
