- Increased depth of countersinks in the T-407 to accommodate the dimples in the T-703 Tank Rib. Used a 1x6 block to hold the ring in place while machine countersinking the nutplate rivet holes. A little concerned it will leak during the leak test but we'll see.
- Also, the tank sealant, flop tube and access cover plate arrived yesterday. Sealant expires July 2009. So it looks like I will be building fuel tanks sooner than later.
