If you are having trouble with the Roubo’s Folding Bookstand article from the February 2011 issue of Popular Woodworking Magazine, I urge you to attempt to lay out the joints on some wood and give it a try. If it still vexes you, however, then this short video might help.
Disclaimer: This may or may not be how Roy Underhill lays out the joints. I did this from memory after reading the article a couple months ago and looking at a photo of the bookstand on my blog this evening. (OK, yes, I don’t have a copy of the February issue at home.)
