Jan 24, 2024     Flaps - (12 hours)       Category: Fuselage

Started working on the electric flaps… to begin, I had to cut down the center bearing block, drill #10 holes in it, cut it in half and cut a 1/16th” notch in the forward bottom piece, oh and up drill the holes to a 1/4”. The flap weldment was then placed in the fuselage, fit with the side bearing blocks that were fabricated earlier. Next was to match drill the #10 holes into the the floor skin and bulkhead flange. These will apparently get nut plates. Onto the SB for the flap motor/rod. I have to drill a small hole in the top and side of the flap motor rod so that I can put some safety wire in to prevent the jam nut from turning. I tried a super small bit and it broke off, so with a ton of effort and destroying a couple bits, I finally got the holes to meet. Definitely a very dumb fix. I'm thinking possibly a lock nut that matches the rod end threads would be better but I don't know, we will see how the longevity works out, oh well it's done. The baggage floor tunnel cover also needed a notch cut to prevent it from interfering with the center bearing block. I had to fabricate many little pieces to install the flap motor within its housing cover. Those were deburred and primed…….. More to come,
