I'm building my first LT 40 Arf. I've been advised to add more Sig Easy hinges to the elevator control surface. Would a tool like the Dubro Hinge Slotter be the ticket for adding a couple additional slots. This is inexpensive and can be used with X Acto #2 handle to dig a new trench. Also its been suggested to pin or tooth pick through the control surface and the hinge. How do you do that without messing up the Oracover? Do you need to seperate the Oracover away from the hinge slot to get the CA in properly or should it be left alone. Lastly the Sig instructions say to use 3 - 4 drops of thin CA on the hinge when the control surface is in the deflected position. Is this 3 - 4 drops on each end of the hinge or in the center to spread to each side? Thanks in advance, Rob P.
