I had a problem yesterday with riveting the HS-714 spar piece. I was using the pnuematic squeezer and must have had a problem with the lip sticking up and rivets didn't seat very well. I tried to remove them and had a bunch of problems.
I practiced with about 10 rivets and scrap metal and figured out that I was doing the following wrong:
- Didn't drill deep enough
- When the drill goes in crooked, simply aim toward the center
- Drill SLOW
- Start with small bit, then go bigger.
- Don't be afraid to give it some firm whacks to pop out rivet - with good support underneath!
I do learn from my mistakes, and spend a few hours last night cussing at it. After practice, I had each of them out (from the shop end) in just a few minutes!
So, I have three holes that are kind of ugly right now, and wanted some opinions if this seems ok to build on with these.
You can see that I missed the center of thee rivet (and lack of practice) and dinged the edge of the holes. I cleaned up the rough edges with a little deburring and scotch-bright. I'd like to spray a coat of primer on again and move ahead. Just wanted to see what you guys think of my mess if there are any suggestions. The holes other than the outer part are still round, and the rivets have a good fit still.
Thanks again for the help, this forum has been excellent!
