What am I missing here? Step 1 calls for drilling the holes in the blocks with a #10 bit, but the holes in the ribs for the bolts (AN3) are #12. Why the (slightly) larger holes in the blocks, especially if you're using them for guides to match drill the #12s in the ribs?
RV-10 empennage done for now. Wings done for now. Working on the (SB) fuse (Section 40: Flap System)
