Hey there everyone, and thanks again for all your offers of support.
Twas a busy weekend (taxes finally and a massive "honey do list"), but I did manage to have my fun. I broke out my old tubes of oil paint, with the caps impossibly glued on with old dry paint, and went to town on all the interior wood in this beast of an armed flying yacht.
I thought about actually doing some research, well I did a little. I wanted to know what type of woods the actual plane was built out of so I could make an attempt to recreate it. I ended up just seeing everyone else's fine work and couldn't think about anything but getting started on mine. I noticed that most had a combination of darker woods on the frames and structural members, and lighter colors on the floor boards. Good enough for me, time to start.
I did make one big diversion from the norm that I was seeing in everyone else's work, as well as the instructions. The bottom of the plane is black. I hated it in every picture I saw. It was always this beautiful, pleasantly hued, natural looking shades of wood, and this monotone, stark black on the bottom. So the rebel in me said, "no way" and I went for a dark brown wood instead.

For the colors of oil paint..
A base solid color of Yellow Ochre
This looked so weird when it went down that I panicked a little, but went with it anyway
Burnt Umber for the dark wood
Burnt Sienna for the light stuff
Basically I just messed around with the paint in a few different ways, but it all ended up coming out the same way. It mixed the base and the next color and put subtle lines of different hues that looked just like wood grain. Wonderful!
I do have a couple issues. Seems the wood grain goes in the wrong direction in a few places. I didn't actually notice it until I looked at the pictures I took. Also, I may have overworked the paint in a few places, creating a whole different color and loosing some of the wood grain effect.

Two tone painting like this is a little tough. It tends to bleed over into each tone. It's likely my poor choice of brushes that's the cause, but next time it'll be a trip to the craft store to get some cheapo stiff brushes in various sizes to make things a little easier to do.

Overall I'm happy with the way things turned out. I'm a little miffed at how the oil paint is so thick and that it's covering some of the fine detail, but I'll have to learn those little tweaks on the next few models. I really like the look of the fine wood grain. I considered adding larger grain work with a detail brush, as well as maybe some knots and stuff, but I'm way too lazy. I checked the parts today when I got home from work, and they are still way wet. I hope things will dry up by next weekend so I can start poking paint at all those fine details after a protective coat of satin varnish.
P.S, Got some goodies to improve an already fine model. Jeez I'm a detail lush.

Take care everyone
