Building shelving, newbie questions
I'm building a small shelving unit that I'm going to use to hold my A/V equipment (cable box, receiver, media center, etc). I'm building it to fit a small nook I have that's around ~40" high and 22" wide. The shelf will be about 20" deep. I'll be adding wheels to the bottom to allow it to pull out for rear access. I'm building it out of 3/4" birch plywood, and will be adding a face frame of poplar. I've already picked up the wood from a local lumber yard and have the frame pieces cut and dados routed. I'm planning to start the joinery tonight.
This is my first real project, so I have a few questions for the pros out there.
1.) I've cut dados into the sides to receive the shelves, and plan to glue them in place. I will clamp them and allow them to set. Is it also necessary to nail or screw them, or is glue sufficient? If it is, will finish or brad nails work?
2.) Is it ok to glue and finish nail my face frame onto the shelving frame piece by piece, or does it need to be assembled seperately and than attached as a whole?
3.) For rear access and ventilation purposes, I do not want to put on a plywood backing. I've read that without one, racking can be an issue. Is there another method to help prevent racking?
Thanks for any advice you can give.
