I am about to start on my next project and could use a little advise.
The project is a moving bookcase. Specifically it will sit in front of the door way to a closet and move side to side to open the closet. It will be moved by a linear motor. The motor has a lift rating of 140 lbs, so with the book case rolling, weight should not be too much of an issue. (We don’t actually plan on putting much weight in it, it will be used for display more than books.)
Still the bookcase will take quite a bit of force as it is opened; plus the force will have a tendency to twist the book case because it is applied from behind and outside of the bookcase.
So my first concern is that the joinery be able to take these forces everyday for many years. I have never built a piece of furniture that moves.
My second concern is what wood to use. Obviously it needs to be strong, but I am trying to match the color and grain of other wood in the room (which is all pine stained with Minwax’s Golden Pecan). If you look at my blog entry about the cabinet I just finished. You can see the color and look: http://lumberjocks.com/GeneL/blog/15152.
I had thought about using oak instead of pine for this but I am afraid it will not look too much like the other wood. I also thought about using aspen because it is very light and should stain out about the same, but I just don’t know about the strength.
I had planned to use plywood for the sides of the case, does anyone think that solid wood would be a better choice?
Here are some drawing of the planned book case:
