Maybe get JD Brewer to do a quick video on his steel sawhorses? Hinge part number from McMaster-Carr would be great.

Started to pimp out my new Millermatic 255 to make it as self contained as possible. Made with scrap/offcuts, so it's a mix of steel and aluminum. The post/shelf is bolted to the mobile base, so the 255 can still be popped off the cart, and shelf is high enough that the access door clears it.
