Hi all,
Being the type of person who goes crazy without a project to work on, and being tired of renting 172s, I bit the bullet and have started an RV-9A build. Have a few degrees in engineering, so I'm somewhat mechanically adept, but have no airplane or metal experience, but excited to learn. This leads me to question #1...
Am getting ready to fabricate the L and R HS brackets (ie, step #1) and have accurately transferred the pattern to the angle aluminum. I know that I want to do my rough cut a bit away from the final dimensions, but how much? How much can I expect the clean-up and finishing to take off the aluminum? I'll err on the side of caution and start slow, but if anybody could give me a rough guideline on how much metal to leave around the edges it may save me a little guesswork. Also, should I initially drill the 9 holes with a smaller pilot bit and then enlarge? Looking forward to the day that this type of thing seems like a stupid question to me as well!
This site has already been a great help to me, so thanks for that, and in advance. If any Tampa Bay area RV'ers want to trade some newbie instruction for grunt work and manual labor, let me know!
