I think these plans are fairly common, may well have been posted here before but I stumbled on them along with some good pictures. I can't drag the pictures and all over here so I'm going to post a link. Seem to remember the folks running this site are pretty tolerant about such things. The site I'm linking to is the opposite, they aspire to be the only site on the web! Good folks other than that and a few other quirks though. Please zap this thread if I have committed an oops and apologies.
Never really tried to build a folding sawbuck, spent a plenty though and that was something the ex was expert at indeed. No need to fold one with her around, it wasn't gonna last long enough to make it in a wallet anyway! OK, enough ragging on my ex, she is wondering what the heck that sharp stabbing pain in her side is and she is actually a pretty good ol' girl.
Here is the link, and wishing y'all a happy Thanksgiving, it is about fourteen minutes away here.
