That is a great looking desk KJ.
Just wanted to jump back in here and give you guys a quick update on this project. Its part of a much larger finishing basement project so I am finally getting back to this sub-project. As you can see its not quite complete but close. The built in shelves i used 1x10 pine and then hit the front with some finish trim. For the desk drawers i have to admit i bought them at an unfinished furniture store.
The desktop itself though I ran some 2x3 around the inside perimeter and nailed that in as a cleat and then attached some 1/2" ply and secured that to the cleat with some screws. Then I put a nice piece of 3/4" red oak ply on that and secured it with screws from the underside. Then i ran some 1/4 round trim around it where it hits the wall. Got a few more coats of sanding and poly on desktop to go and I have to finish the trim above and to the right of the desk but you get the idea.
Kel that looks awesome, man....I've been wondering how this project was going to come out. You did a good job, and a number of things right....the two layers of plywood, the ledger on the wall first, the finish trim, screws from underneath. I wouldn't worry a bit or appologize for buying something at a store to fit into part of your project. I might never do it, the next guy wouldn't, but if it fits your project and it is what you're comfortable doing, then by all means suit yourself.
Again, great job so far, and keep up with the pics when you get farther along!
