Here are the pics - all desaturated, so they are nearly B&W... It works well since there is hardly any color in the wood anyway.
I should also mention - I'm colorblind (red-green) so I lean more toward high contrast desaturated photo's anyway since color balance is very difficult for me.
Edit: Looking at them now - I think there is a better balance across all the photos, but I can seem to see some color / warmth I think - so the desaturation in iPhoto must not completely drop them to B&W..
