Heavy Duty Adjustable Height Saw Horse

[Jon]

Very nice take on a common but often lacking tool build.

A very clever design, indeed. I especially like the fact that the working height of the support is adjustable. Most saw horses I've used are just too low to permit working comfortably.

Although I understand why something like kitchen countertop heights are a necessary compromise, standard worksurface heights seem to be unusually low. Not sure why. We have reliable, longstanding data on average human heights, our understanding of ergonomics is well-developed, and we know that lower back pain is both extremely common and costly. Economic incentive to produce worksurfaces with less material, which are thus less expensive? Lingering holdover from an era of universal 36" heights?
