I'm making the tiedowns. When I lay the spacer (W-725) on the spar web, and place the tiedown (W-731) resting on the reinforcement bars, there is a gap between spacer and tiedown. The reinforcement bars on the spar are 0.196" thick and the spacers are 0.186" thick, so the gap is 0.01". That seems excessive. What to do? Do I need to make shims?
If I were to assemble this and torque the bolts that go through the spar web into the tiedown nutplates, the spar web might be distorted or preloaded excessively.
Also, one of the tiedown extrusions I received is a bit tweaked. The two flanges of the extrusion don't lay flat, one side is bent up a bit. Will it just flatten out when I torque the bolts, or should I attempt to bend it flat?
