OK, here are some pics of my Corsair. A couple of them are from last year, while I was building the interior. Recently, I painted the insides of the fuse so I could install the previously finished cockpit. I think only the FAA Corsairs had the black over-painted seats, but I am going to put it into this USMC 'bird anyway. Don't tell anyone!
This weekend, I started on the napalm tanks. I used various sizes of round burs in a motor tool to thin them from the insides to paper thickness. This way, I can just lightly push my fingertip into them from the outside and it leaves nice little dents and wrinkles in the surface. It takes a lot of finesse to thin them down w/o boring right through them, luckily my line of work really helps. Each tank half took almost one half hour to do, that's two hours of grinding! Here's a photo showing one of them done next to one that isn't:
I also weighed them on a gem scale to see how much material I actually removed. Before grinding, each tank weighed 1.9 grams. Afterwards, they weighed .8 grams each. Quite a substantial amount!
