Took a bit of doing but here is a color map that may be useful:
Make wood grain horizontal in green area and vertical in blue area. Top and bench are horizontal grains. Apply overlay and it should work ok. I'm still experimenting, so I will post again soon.
Btw- yellow size: 512x213; red size: 512x114; vert legs blue: 226x185; horz legs green: 286x185; all on 512x512 image
Wraith you can post this on your site if you want (hope the measurements are correct LOL)
