Oh you guys are just too kind!
The sawhorse (portable workbench / toolbox) was dreamed up in the 70's. I posted the drawing in FWW magazine to lock down the copyright. Built in the very early 80's.
I was refinishing a lot of furniture and I needed a way to get my junk into a clients home without making 9 trips. Light as I could make it, and still be strong enough.
I have stripped and redone a lot of stuff right on their porches. No need to drag it across the county!
So, its 30 years old now.
I built another for heavy shop work. This one don't move. 3" thick top.
yours Scott
