Thanks for the help. I'm thinking of using a board underneath connecting the two pieces or a metal fastener. The only thing that has me worried is how i can get a good miter. The boards are very rough and uneven and so I'd probably have to miter by marking a 45 and using a circular saw to make the cut.
The corner of the "L" would be floating (no support by a cabinet).....any ways to best support it? I already plan on using a cleat along the back wall.
Could I run a piece of wood underneath and diagonally across the two tops, behind the apron of the desk?
