I'm New Here
I have recently started on my RV-14 and am about one fourth the way through the empennage kit. I have a question about the the rather subjective subject of deburring. I tend to be rather anal about things, so I wanted to take a straw pole centering around deburring to make sure my thinking is on track.
Section 5 of the plans gives a good introduction to edge prep:
Recently I have been working on my horizontal stabilizer ribs. My approach was to hit all of the flange outer edges with the 3M wheel on the bench grinder, and that went quickly and worked well. But what about the flange relief cuts? The following pictures detail my current approach:
I start by removing all of the roughness on the straight surfaces left over from stamping with a flat file (RED). Then I do the same on the curved surfaces with a round file (MAGENTA). Then I knock off the edges / round on the straight inside surfaces with a flat file (ORANGE) and then the curved inside surfaces with a round file (CYAN). Finally I deburr (hard to really round) the outside surfaces with a 1" 3M wheel in a die grinder (GREEN).
Some of the more convoluted ribs have ~18 relief cuts and after timing myself at what seems like a pretty good clip on any one operation, it is taking me just under 30mins per rib. Is this the norm? Am I over doing it? Under doing it? Any suggestions? Thanks!
