Nice. I would also use Titebond III as it is waterproof; apply WOP where the hinges were placed; used foam weather stripping for a quick application but your cutting foam and slitting the strips is ingenious. My complements on a nice fly box.
Ok. Looking to make a fly box for a friend. Came across this video. Did I already make this fly box? Or is Ackley that common of a name? This is Shawn Ackley… Trippy… Thanks, man!
