Improper Deburring

Unairworthy.

It is really important to remove the burrs that are created when drilling through aluminum prior to riveting. Otherwise the rivets will not get a good, strong grip and will work loose over time. The rivets shown here were at the top of a lift strut. Definitely not a good place to skimp on deburring!

  1. Cogsdill company (Cogsdill.com), makes a series of deburring tools for one pass deburring of both sides of a hole, even a blind hole in a tube. The tools are sized for each diameter hole. They are not cheap, $50-$60 bucks a piece the last time I checked. Perhaps a good item for a chapter toolkit. They even make specialized bits with different rake angles for steel and aluminum.
