Just wondering how "anal" a person has to be when it comes to deburing and sanding on the ribs and such. I understand you should have all filings and rough edges removed from the parts before final assembly but I would like to know just how far a person needs go to make it ready to assemble.. I know someone who used a magnifying glass to do final inspection before assembly but I think it was a little overkill. Never hurts to be that precise but you can waste alot of time doing stuff that really doesn't need to be done. On the edges of the ribs, do you just do light sanding to make it fairly smooth or do you spend alot of time on it? To me, as long as your skin doesn't get scratched when rubbing your finger across it, it should be ok. Any input? I don't want to waste alot of time doing something that really doesn't need to be done. At A&P school they stressed the importance of getting out the pits where cracks can start but never really said that all edges must be totally smooth to avoid stress cracks. Just want to get a feel for what everyone else is doing out there. Thanks.
