Began work on Flaps

Screen Shot 2019-06-01 at 5.37.36 PM

Built the cradles for the flaps. Traced a leading edge rib to make a template which I transferred to the plywood blanks. I used the bandsaw to cut out the cradles. I glued and screwed some 2×2 stock to the bottoms so I can clamp them to the bench.

 

Started work on the flap attach brackets. Laid out and drilled the holes in the flange of one of the left halves of the bracket. Then match drilled the other three and deburred everything. The right halves get drilled later in the process.

Begin work on Section 17: Outboard Leading Edge

Picked all the parts for the leading edges. I cut the splice strips from the tank skins and trimmed the tabs from the cover plate doubler using snips.

Cut out the leading edge cradles from the shipping crate top. Forgive the blur in the image… I photoshopped out my address from the top of the create.

Cut the 2 x 4, glued it, and screwed it to the cradles. Clamped them to the workbench

Off to Nashville for a conference tomorrow… Sophie said she’d prep (peel, edge deburr, and scuff) all the parts while I’m gone. So should be able to begin fabrication and fitting when I get back later in the week.

Prepared HS Ribs

Deburred all the HS ribs with 400 grit sand paper. Sand paper seemed like the most straightforward approach because of all the segments in the flanges. I was able to get in between the segments with it.

I fluted the ribs and modified the two nose ribs and two inspar ribs per the plans and marked them.

I drilled the inboard nose and inspar ribs to the forward spar. Then I deburred all the holes in all the ribs and then dimpled all the ones that mate up to the skins. So. Many. Holes. I can’t even imagine what the wings are going to be like.

I also created a template to make cradles to hold the HS when assembling. I’ll scrounge some plywood to cut them from and some sort of square stock for the bases.
