I am trying to keep both sides of the wing build at pretty much the same level. The left wing has a few more items to do than the right and then you have to wait for epoxy to set up which gets you started on other things. So today was a bit of catch up. One of the options in mounting the butt ribs is to use #6 screws rather than rivets to attach the mount brackets to the actual butt rib. That allows you to remove the rib for painting and such should you decide to at a later date. I liked the option so that's what I did. #6 stainless steel screws and self locking nuts. Got both sides installed on the fuselage along with the bending and fitting of the flange that goes on the bottom of the butt rib. You bend that flange to shape which is what the vice grips and two pieces of steel are for; a cheap bender Also finished installing the last of the false ribs. They had warped just a touch so I epoxy'd in the fronts, let them set up and then flexed the rear of the rib to straighten them, held them flexed with the tape and epoxy'd the rear of the ribs to finish the job. In reading the Garmin OAT installation instructions (yeah I am breaking the bro code by reading the directions) they indicate that they like the sensor to be set on metal and grounded along with the grounding wire in the harness. So one pic here is the install of an aluminum strip that the OAT will set on and a screw that will act as a grounding point and get wired with an aircraft ground. Last but not least, I riveted in the plate nuts on the pitot tube mast. Lots of little stuff done today.
