A set of sawhorses always comes in handy – until you put them away. They’re hard to stack, and they take up valuable space.
If this sounds like your experience, build a pair of sawhorses that “knock down” for storage. Besides saving space, these sawhorses can be assembled (or taken apart) in just a few seconds.
Each sawhorse consists of a long stretcher that fits down into a notch in two A-shaped supports. Drawings and details here.
This plan was one of the weekly woodworking etips from Woodsmith and ShopNotes magazines a while ago. You can have tips and plans like this sent to your emailbox each week (they're free).
BTW: The guys over at WoodNet Forums are sharing photos of their sawhorses.
