I think it depends! You have two screws that belong to one arm. One screw goes through the arm and the other one is the limiting one when you fold it out. What I did this time is not take the inner one as the screw that goes through the wood. No I took the outer screw for the one that goes through the arm and the inner one (the one closer to the CG) as the limiting. I was playing around with it and thought that no stability was lost with this because you placed all the wholes for screw closer to the CG anyways. I hope you know what I mean.
Oh, I see what you mean. I actually designed it to pivot on the outer screw instead of the inner screw. I did that for more sturdiness!
