I used some 320 sandpaper to remove all of the file marks from the cut for the Dynon—took more time than I was expecting. Next, I marked the location for the mounting holes, center punched, and drilled to #28. A #6 screw requires a #27 hole, but #28 gives a tighter fit. I used a nutplate jig to drill for the first nut plate and ran out of time. Will finish up the other 5 holes next time.
