Am I being to pedantic here? Every other rib is fantastic. I wouldn't even know HOW to fix this...

And after a COVID USPS delay, and some other stuff I needed to do (like house reno's) I finally got back to this... The fella's sent me a new angle that I could match drill to get the right height....

Rodger and Greg had similar issues...the front tab is rounded and doesnt sit nicely to the spar. If you file the tab flat right at the spar that tab should drop down just enough. Also the rib attachment corner pieces to the spar and the rib edges did you make sure they were at 90 deg. The rib edges you need to tap with a block of wood while the rib is flat on the bench to make sure all the pressed edges with the flutes in them are 90 deg to the main body of the rib

Hey mate.... this is root rib on my right wing... this, I would have thought, would be like all the other wings, and transition nicely onto the spar, but for a reason I cant work out it sits maybe a mm high... I thought while doing it that maybe the skin ends there but it doesn’t, so I think if I proceed it will have a pretty nasty bend down to the spar...
