How To Make A Three Position Box

The Bell Systems three position stool was a mainstay of the central telecom office. It was typically constructed from red oak and 2 inch screws. It was a was a real workhorse, just what I need...

My box is scaled down a bit from the original stool but fits well in the shop.

It measures:
 22.5" high,
16" wide
11.5" deep

I made it from 3/4 maple and a piece of plywood for the bottom.

 It is perfect for reaching to the top of the lumber rack, changing light bulbs, as well as sitting at the bench. It's also a great step up to tools and tables for young woodworkers.

It is already become invaluable. Thanks for looking!
