Three-Legged Knock-Down Sawhorse

Featured
The more projects I make, the more I realize that my rickety old sawhorses are inadequate. I think that I am limited by the strength and sturdiness of these sawhorses and I feel like I am always compensating for them. Because these sawhorses are so unstable, I set out to make the most ideal and functional replacements I could.

Ideally, my new sawhorses would be extremely sturdy and collapsible. That way I could take it anywhere and easily put them out of the way in my small workshop. I have a reprint of a woodworking book from the 70's that showed a couple different designs for sawhorses. The one that interested me most was a 3 legged design that touted its sturdiness on uneven ground. My backyard is very uneven and I often have trouble setting up tables or my sawhorses. I reposition them again and again until they stop wobbling.

Unfortunately, the book only had a rough drawing of a 3-legged sawhorse. I looked around the internet but I didn't find any plans for a 3 legged sawhorse, so I had to design my own. I decided I wanted to make my design include knock-down legs, so they could be taken off for storage or transport. I used the following links as guides for the standard parts and adapted a traditional knock-down design to suit my needs.

Great design. One thing comes to my mind- why not make few more holes on the single leg- that way will be lighter to carry and wont lose lots of strength!

Excellent instructable. Decided I needed a set of saw horses, so this was a perfect first project for my budding wood hobby. Super sturdy, and though mine aren't as nice as yours, they are actually sort of nice looking for saw horses.

Thanks a lot. Do you have any pics you can post?
I really like this style of saw horse. Thank you for posting it. I did have one idea, have a 2x4 laying flat screwed onto the top of the horizontal piece to use as a sacrificial board so you don't have to remake the cross piece.
Good design. I tended to use plywood gussets on the legs to avoid splitting of 2X bracing. I also found nails have more lateral resiliency than self-threading screws (screws would break occasionally). That being said- I regularly loaded 'horses' of this design with 1500# of lumber...I don't necessarily recommend this practice! (it was production expediency and we took risks a sane person would not)

Thank you. The three-legged design makes the sawhorse stable, even if the ground surface below rolls. This would be especially helpful when used on a lawn.
It would do, unlike a four legged one, or a table. You KNOW they're always going to have one leg adrift and start rocking.

For stacking them could you not switch them end for end so that the single leg falls between the double legs?
I'm sure it's a fine tool for sawing, but I can see possibilities beyond such mundane "work-a-day" uses. It seems like an eminently stable and useful structure for all kinds of furniture. Thank you for posting it.
