We're glad to have you. :)
Looks nice mate! I'm no woodworking guru but I would suggest that you evaluate the wall/screw fixings and the possibility of the wood bowing carefully. Books etc can be very heavy, and if the wall screws and fixings pull out things will get ugly.
There are a couple of websites I've seen that let you calculate the bow of a span of a given material over a certain length, search up a couple and figure out what weight you want the shelves to take.
Sunny Friday for me, gonna catch up on some filing and reporting and cruise into the weekend.
Working on keeping power falling out of the walls for everyone, maintenence at a power station. It's been a busy week, I'll be glad to wrap this one up and chill for the next couple of days. The forecast is OK so might mow the lawns or something this weekend.
No idea, but what a great plan! Good luck!
