Latest from the East Fork. In order to make your building experience more tailored to fit your needs/materials/skill level, I have uploaded the map cabinet/ safety glass-topped occasional table to the Sketchup 3D Warehouse. Download, look around, edit to meet your mood and space, share with your pals. You can find the fully accessible model in all its 3D glory at http://sketchup.google.com/3dwarehouse/details?mid=e96bfb93d0ccc70b6644f2a1e354446e 
All of my builds are made from 100% reclaimed material. Why? Because it's fun, inexpensive, challenging, and I'm a tree-hugger. It takes a bit of effort and some reverse engineering. The traditional build has plans and calls for materials. My build has materials and calls for a plan.
How does that affect your build? Well, if you follow my plans, you might go crazy looking for a 31-3/4" x 24-1/8" piece of safety glass, and I'll feel terrible for requesting you spend a fortune on hardwood lumber only to mill down perfectly good boards to match my dimensions.
So please, amend as needed.
During your build, I encourage you to be safe, creative, and awesome (like you always are).
If you have any questions or would like more guidance on a "re-plan" to fit your build, please ask.
Build happily, friend!
