The front of the stabilizer's ribs need to be sanded to precisely meet the balsa leading edge as well as keeping the front of each rib plumb. To accomplish this task, I have sandpaper attached to one side of aluminum angle stock.




With the sandpaper meeting the edge of each rib, all that's needed is a couple of passes to get each rib exactly where I need them to be.




Mission accomplished, now it's time to glue the two sections of the leading edge to each rib...






But first, I have to determine the angle at the front of the stabilizer. Using a protractor, I found the angle to be 13 degrees.




Each of the LE ends will need to be sanded at 6-1/2 degrees. Here I've adjusted my protractor to 6-1/2 degrees, now I'll set that angle on the disc sander.




With each LE end now sanded, it's time for the glue-up.
