A few days ago, when I installed the rear seat throttle mounting plate, one of the platenuts seemed to be defective or stripped. Today I removed the plate and found that when I installed the nutplates, a #10 nutplate had apparently been mixed in with my drawer of #8s. Yep, that'll do it. Needless to say, I removed it and replaced it with a #8. I also finished trimming the pushrod holes in the bulkheads and the F-804 vertical channel cap. I prepped and primed the throttle arm, the pushrod, the throttle mounting plate, and the shims for the mounting plate. While they were drying, I un-clecoed and removed the UHMW anti-wear plates and widened the inboard side of the throttle-arm slot by 1/32", and also lengthened the front end of the slot by 1/8". This will make sure the rear-seat throttle does not rub, and does not limit the throw of the front-seat throttle. Next, I worked on the Andair fuel selector mount some more. I drilled the aft support angle for two #8 nutplates, countersunk all the holes in the longerons that will eventually take rivets, then prepped and primed both support angles and the valve mounting plate. The valve mount is pretty much ready to install now, followed by the fitting of the fuel lines.
