Q: What does this piano stool mechanism include?
It includes a seat base and threaded shaft assembly plus a matching steel nut, giving 6 inches of height adjustment once you build a base around them.
Example of completed piano stool
From 1879 to 1932 the Otterville Manufacturing Company designed and built many consumer items, from mechanical carpet sweepers to Victorian folding screens. One of its better products was a height-adjustable piano stool; today it is much sought after by antique collectors.
We have remodelled that mechanism to make our piano stool mechanism. It includes a 3" long machined steel nut (for insertion in the stool base) plus a 4 1/2" diameter seat flange fixed to a 1" diameter by 8" long threaded steel shaft. The #6 and #12 fixing screws needed are not included, since their length will be design dependent.
A unique feature of our redesign is threading only the bottom third of the nut. This avoids toppling of the seat if the shaft is spun out of the threaded portion. The system still provides 6" of height adjustment.

No, fixing screws aren't included, so you'll need to supply wood screws sized for your own stool design.
No, threading runs only through the bottom third of the nut, which keeps at least some engagement at all times so the seat can't spin free of its base.
Yes, the mechanism is a redesigned version of hardware originally made by the Otterville Manufacturing Company between 1879 and 1932, which remains popular with antique collectors.
Yes, this is a hardware kit rather than a finished stool, so you'll need to build or supply your own base, cap and legs to complete the piece.
