by H. G. Carter
To make an adjustable surface , the ratchet mechanism is as simple and reliable gravity. The cabinetmakers of the 1 8th century frequently used single ratchets (Fine Wood working , Spring ' 76) to support adjustable slanting tops for architec t ' s tables, writing flaps, reading rests and music stands.

Its double jacking mechanism will rise from the closed height of 6- 1 1 2 in . to a full 20 i n . , j ust right for supporting the legs, whether they are tender from the gout or simply tired from jogging. If the jack were made stur dy enough , and the reactive mechanism and pivot pin strong enough , there is no reason why a large tabletop, elevated platform or even a chair could not be raised and supported . The material layout shows how the entire stool , including leg glue-ups, can be cut from standard 1 x 1 0 stock, 65- 3 / 8 i n . long . I find the glued-up legs acceptable because they are masked by the overhang of the lower frame , but purists will need an additional piece of material 2 - 1 1 4 i n . x 2 - 1 1 4 in . x 1 6 i n .
