Hi Guys,
I was wondering when riveting trim hinge to trim tab if all three items being the skin, hinges and trim tab spar are dimpled or is hinge countersunk ?
Thank you

IIRC, dimple the skin, c-sink the spar, and don't do diddly to the hinge.
Same setup when you rivet the flap hinge to the wing. Wing skin is dimpled, brace is c-sunk, hinge is left alone.

Thanks Dan,
Also, with rod end bearing for attaching elevator to HS. To get all perfectly in line did you just count the amount of rotations on each as it threads into the plate nut ?.

Sort of. Van's plans call out suggested dimensions for the rod end bearing, distance from the spar or something like that.
My 2 cents is -- don't sweat it until you're ready to mount the rudder on the VS permanently. Then you just make sure you have (a) alignment of all the rod ends with the hinge brackets, (b) rod ends adjusted to provide full range of rudder travel without any chafing or interference, (c) counterweight arm is aligned with the top of the VS and doesn't interfere.

I'm just now working on mating the elevators to the horizontal stab. I have initially set the rod end bearings as per the plans. I'm getting ready to drill the elevator control horns but they are not square to the main center bearing or to each other. I was just about to email Vans (as the plans don't go into much detail here) when I saw this thread. Are the elevator rod end bearings supposed to be adjusted until the horns are square? This would mean each rod end bearing will be a different measurement from the spar and the counter-balance arms will not be exactly parallel to the horizontal stab as they are now. What have others done here?
