Bending up Elevator Trim Tab Riblets

[atalla]

Hello all

I like many have opted out of the trim tab bend over tabs and have made Riblets instead

I did riblets as well but I ended putting the web of the rib on the interior side of trim tab so the flanges were accessible which enabled me to set solid rivets through the control horn area. I still ended up using MK-319-BS rivets in the aft most holes simply because it was too difficult to get solid rivets in there.

You'll love the longeron yoke. Surprised you made it this far without one!

Same thing I did too. I also just bent my riblets on a break, took a few tries but it went quick.

Great idea flipping the rib around. Why didn?t I think of that !?!?

Thanks!!

Here are a few shots of the process of building my riblets (they sound delicious, by the way):
