I usually make this sort of thing but, the combination of dealing with a failed water heater, a personal project for the house that is taking too long and a Lowe's gift card from a well intentioned admirer led me to pick up a couple of these in the dent and ding bin. I love my two height assembly table and use the legs with and without the table top. The tallest height was a bit low for the current project and the benchtop was too high. The saw horses adjust but, the lowest height is about 25" which is about as high as I would ever need. I lopped the legs off and drilled a couple new holes for the wingnut and bolt that secure a given height selection (along with the keyhole pins like a lot of quick-assemble metal fixtures use).
I figured out a height that would meet my needs and leave the height adjustment mechanism functional. I wanted to knock about 9" off of the height so I cut a piece of scrap to this height. Using this as a marker got my height and angle in one shot.
Here's the result at the lowest and middle height.
And here they are at their new highest setting. My aching back feels better already .
