Spent some time deburring the front spars, before doing step 21.Step 21 - Match drill, countersink the reinforcement angle, and dimple the tabs of the front spars. I cleocoed everything together in order to get the match drilling, and from there did the countersinking and dimpling without a problem.Step 22 - Here you have to cut a notch in the backs of the front ribs. See picture 2. My Dremel worked pretty well for this, but I didn't get the outside cuts as straight as I would have liked. I will wait and see how these fit before filing them straighter. Of note, each notch is a different length. Depending on if it's a right rib or a left rib, the longer notch is on the opposite side.
