This was a good project and I'm not very advanced. I increased the size of the table top to 60x28 and decided to just increase the width of each drawer by 6" and keep the aprons at 6" I was able to find a piece of oak plywood that added to the cost but I have two big pieces left over for future projects.
One thing to watch out for - the cut list says the leg trimmings should be 25 1/2 but the drawing shows 25 3/4. Shame on me for not adding it up, but I ended up having to trim 1/4 off the top of the center leg boards before putting the plywood on it.
On the top I measured out where I put the drawer housing support screws, overscrewed them then added some 3/8 flat oak caps. I also did this at each corner into the legs. I think it gave it a nice worn look to offset the modern feel of the desk.
