Hello everyone, I'm getting close to finishing my empennage on a 8A kit and have a couple of issues that have come up I'm needing feedback on. 1st, the drawing calls for MK319 BS blind rivets for attaching the elevator skin to the trim spar (the 4 holes on the end). After inserting these in the bottom I have come to the conclusion that I don't want these round headed rivets on the top skin where everything is countersunk. Is there an alternative countersunk blind rivet I could use? 2nd, I trimmed my left counterweight before I saw right side only. Is this a problem or is it trash (it's all bolted and riveted in)? Thanks so much for your input.
