I built four Krenov-style sawhorses about ten years ago and they have served me well. I made them from softwood lumber (pine, I think) using through mortise and tenon joinery. I wedged the tenons of the stretcher, but elected not to reinforce the leg-to-foot joints. Recently, on a couple of the horses, those leg-to-foot joints […]

I graduated from SFSU in 1977 and began my teaching career in Las Vegas that year as well. Like so many others at that time, subscribing to and keeping all of the issues of Fine Woodworking magazine was …
I loooove me some blankets so in my living room. I have plenty of them however, I don’t have any place to store them so they are scattered everywhere. This week I’m fixing that by building a coffee table that has storage inside. I was thinking about building one of those tables where the top actually lifts up and turns into a surface to eat on (while sitting on the couch) but we actually never eat in the living room so I figured I would stick with a more traditional style of having a hinged lid that opens. For the hardware I used special hinges called torsion hinges and even though these are kinda pricy I picked them …
