03/24/13 - New Aft Root Ribs
Dan cranked out two new aft ribs and since we knew they we for the root positions he did not have to make the front and back flanges. He trimmed them a little longer so we would have plenty of edge distance from the first row of rivets: Positioning the root ribs with the others: …
03/21/13 - Too Short Aft Root Ribs
After we trimmed the aft root ribs per the dimensions on the plans and got them positioned with clamps it looked really good. (We were working on the left wing aft root rib.)

03/13/13 - Wing Root Ribs

We located the gussets to the ribs. There are a lot of holes on those parts Match drilling the ribs to the spars took some thought. Since we are scratch building, the pilot holes are located in the spar and the rib flanges are blank. The basic process for the right wing was: 1) Lay …

Dan located the forward ribs for the right spar. The method on the plans uses sheetmetal strips of the skin thickness to get the tangency between the spar cap and the ribs. Sometimes the flange of the ribs were a tiny bit under bent but we are sure the rivets will pull everything tight. The …

After cutting out the gussets had to clean them up. This includes filing and sanding all the edges smooth especially in the radius between to flange bends. This is a detail where one can be really picky since the radius should be tangent where it meets the straight edge of the flange. Here is a …
