I’ve been fighting one hole for the last 24 hours. Drilling the 1/4” bolt holes for securing the horizontal stabiliser to the aft fuselage on my 14 tail dragger I elongated the bottom one and Vans told me to upsize to next bolt size (AN5). Well I screwed up that too. I believe I have the edge distance to upsize to an AN6 but I’ll check with mother ship first .
So if I can upsize to an AN6 I dont want to F it up again. What would you do to stack the odds in your favor of successfully upsizing this hole and have it be clean and perpendicular?
