Part Three - How To Install Robart Hinge Points

This is the 3rd, and final tutorial on installing Robart hinges. Sorry for being so long winded, but I hope that you find this information helpful.



After completing steps 1 & 2 (but not #3) on the aileron, now is the time to create the 45 degree beveled edge. Here I have the aileron clamped into place.




With the bevel completed it's time to perform step #3, creating clearance for the knuckle. Note how the center of the bevel falls directly over each hinge hole.




This is what I use. Simply stick a piece of 220 grit sandpaper on a deep socket.




Position the socket directly over each hinge point hole and slowly sand the bevel to create the space for the knuckle. This is what it should look like.




Sorry, this pic is out of sequence. In this photo the hinge is installed in its hole after completing step #2, but before the 3rd step.




Looks about right.




Time to see if it fits.




I barely have any hinge gap, that's a good thing.




This is what it should look like completed. Now you can see the notch made with the socket.




It's time to fit each aileron servo on their respective hatches.
