Thanks for all the kudos. Looks like it has generated some inspiration for some of y'all.
Here are a few thoughts...random thoughts.
- The thinnest frame members are 1 1/2 x 1 1/2.
- The frames are attached to the wall stud with a couple of 3 inch construction screws (via #25 Torx head). They are sturdy, but just remember, these are light duty and not meant to hold heavy stuff. Toilet paper and pictures, etc.
- For attaching the frames where there is only one stud, a toggle bolt (or something similar) has to be used. I have found these toggle bolts (see pic below) to be the easiest to install and work great. When installing, I determine where the stud is, and where the toggle bolt will go. Then I install the toggle bolt first, level the frame, and then drive in the construction screws into the stud. Really is an easy installation.
- Wiggle room is a good thing to have. If you are installing more than one shelf, a little side to side adjustment is a good thing so you can align the shelves vertically. I don't see a need for a snug fit. Probably because my snug would turn out to be too snug. In fact, on a couple of the frames, I attached the end support arms about an 1/8th inch inboard just in case I had to trim the back piece if it was too snug.
- I attached the boxes with 2 wood screws on top. They are there just to keep the box from moving around.
Hope this helps.
Note: I do have drawings if anyone is interested.
That's my story and I'm stickin' to it!
