So a few months ago a TreeBuzz trade happened. Fellow Buzzer Javier (jf192 i think is his screen name) had some slabs of acacia that were cut down at his place of work...the San Diego Wild Animal Park. He offered them to me in exchange for some splicing. I did some used Fly, Poison Ivy, and maybe a few other things and in exchange I got 3 pieces of what I'm sure is Acacia melanoxylon. Each was about 6' tall, by about 24" wide, by about 2-4" thick.
They looked like this to start:

They were cut with a chainsaw, so they had some pretty rough marks on them. I took them to a local shop where they were able to plane them for me. I ended up with some mostly smooth, even thickness.
A friend of mine has a pretty good woodshop. He turns bowls daily for a business. He let me use his tools. Some of the boards were splitting pretty bad:

I started by cutting the boards to about 7" in width, basically cutting the cracks out. Even though some were about 2" thick and others were closer to 2.5", I joined them all together, creating a slab that was 6' x about 28".
I sanded, sanded, sanded. Then used a mini hand plane to round the edges, then sanded some more. Started at 80 grit on a random orbit sander and eventually worked my way up to 400 grit. I put on as much tung oil as it would take it. Eventually it looked like:

A couple more sandings with 600 grit, and more tung oil and she finally looked like:

The desks we have at work are a simply plywood with legs on the right side. The left side rests on a file cabinet. The finished product looks like:
