I have made a few modifications to my Sketchup drawing and have now bought the lumber. I have in fact lowered the video monitor height - as someone he re suggested - but not as much as some people advised. The height will end up being the same as I had been using for a couple of years, so apparently I like it that way. :)
After asking here about how I might bend some solid wood edging to finish o ff the curved ply edge, I decided to just go with solid lumber. But that br ings up a few other issues.
I had originally planned to use rabbet joints for the cubbyhole joints unde r the speakers, as shown here:
... and I may still. I would make them with a router. But now I'm consideri ng whether I might experiment with lock-miter joints. Any advice? Are they tricky to set up? Do you consider the side view of such a joint ugly? (ther e won't be any face frame)
Then there's the (bigger) question of how to fasten the cubbyhole upright p iece that's closer to the middle of the shelf. In the drawing it's shown as a butt joint, which I won't be using. But what to do instead? It will be e nd grain to long grain, if that's not obvious.
I'm reluctant to use a dado, as I feel it might weaken the shelf. Here's wh ere someone will likely tell me that as long as the dado is filled - snugly - it will be just as strong. Is that true?
There won't be any stress on the joint, so it may not matter what I do. But I like to improve my technique. I could use biscuits. I'm aware that many claim they provide mostly alignment, rather than holding power, but simple gravity would almost be enough in this instance. I could also use dowels, w hich I think might not be a bad idea.
