Hello Guys, I'm a new RV8 empennage builder. So far I'm done with the horizontal and vertical stabs. Which despite this post's question came out quite nice.
My question is about deburring rivet holes. It seems that on about 50% of my deburred holes, the deburring bit leaves a burr just as bad or worse than the drill bit did when I drilled them to size. I'm using a single hole deburr bit, it's new, the correct size, not worn out, in an electric drill. I usually do 1-2 turns with light pressure, anymore and it starts to countersink as you would expect.
Looking for advice or recommendations on what you've found to be the best to deburr the holes in the skin. I don't plan on priming the skins on the inside, so I'm trying to stay away from scuffing them up too much with scotchbrite. Although I've found that the small scotchbrite wheel in the die-grinder works wonders on deburring holes in the structure that I am priming. I'm working on the rudder now and finally decided to ask the question here. I realize also that I may be bordering on being too critical of my own work!!
Thanks!!
