These sawhorses are from ShopNotes
They are adjustable, lightweight (relatively) and
sturdy. They also knock down for easy storage and are made from
inexpensive constuction lumber (2x6s and 1x4s). I finished them
in 2003...and still really like them. They are pretty stable
legs - I frequently use them this way as outfeed supports for the table
As you can see above, they adjust to a wide range of sizes -
from workbench height to drillpress height.
They knock-down for easy storage - the feet fit inside the shelf in the middle. When stacked as shown below, they
take up only 6"x28" of floor space.
