Why would I think this would take no time at all? I will just join the two front pieces on this morning then I'll take my shower. I have plywood bridging the pieces below the floor. Of course they will have to be trimmed to fit flush on the frame. Kind of concerning using a skill saw on a chair leaning against a piece of plywood balancing on a frame. Managed to get it done without hurting myself. Well, not too much. Found my flash, forgot I had one.

I was meaning to ask, I had the idea of using a router and on the top of the floor at the seams, routing a 1" channel and gluing in a strip of wood. I wonder if it would be beneficial or a waste of time?
