Actually last night I decided against capping the boxes for the signs - the thin wood I'd bought was too thin and fragile, and because it would have been a tight fitting cap over the existing box, I couldn't have added any structural support to the cap itself. As long as the cap was on it would have been fine, but if I'd ever removed it, too much chance of it breaking. As for those brackets...yep they're ugly. I like the idea of a table skirt, and not just to hide the brackets - future posts will cover what I want to do with that. Mainly I was using the brackets on this project because I've had them sitting around for the last 10 years and have wanted to justify keeping them by finally using them on *something.* That being said, I like your ideas and it turns out I have a few leftover wood screws. On the computer structure I'll see about replacing some of the brackets. I'll likely leave the big ones in place at the base. I think the wood screws are enough to hold it all up on their own, but I want to be able to disassemble it which rules out using glue, and the brackets take up the least amount of area while providing extra support on the weight-bearing side. I realized the inside brackets now are completely unnecessary and I'll remove those. And the ones holding the crossbars in place can be replaced with long wood screws. For the table, if I can work out how to do the skirt with the legs angled, I'll leave the brackets in place assuming they are completely hidden.
