I made these in 1979 after seeing something similar while driving by some working carpenters. They have been in use ever since and have worn down and inch from being slid around on concrete, etc.. The height is good for reaching 8' ceilings and can also be stacked for 12”, 24”, and 32”. Often used for blocking & lifting heavy stuff, as a saw bench, to hold upper kitchen cabinets, & as a place to sit for lunch. Hammer claw fits in the hole to pick up & carry, sometimes used upside down to hold a spool of wire, & occasionally as a crate. One suffered a broken leg in a fall but eventually had the piece replaced.A year or two ago I was given some plywood scraps & made four more, thinking I might sell them, but they have been put to use as well. If you make some, the sequence is to cut the pieces square, taper the legs, leaving an inch or two straight at the bottom, cut the notches in the tapered legs, fit the sides with the short point even with the top of the legs, & belt sand flat after. Round the edges of the top before fastening to avoid hitting the fasteners. Thin nails are better than screws to not split the plywood- gun nails or staples would be fine. Both the new & old ones have had multiple coats of linseed oil, especially soaking the end grain of the feet.I wrote my name and the date inside of one, & that is how I remember the year that I started my business.Cheers, Jay Read more here
