Note:
You may combine the base and cap as one piece in your
piano stool design.
The legs in our example were made with 1

lumber and cut
with a bandsaw. To ensure the legs are all the same size and shape,
we recommend you make a template. To make the best use of the
wood, the legs may be traced and laid out as shown in
Figure 3
.
Dry fi t the nut, cap and base together before fi nal assembly of
the cap to the base (if two pieces) to ensure the through holes in
both pieces line up with each other. Join the legs, cap and base in
such a way as to produce a secure structure. For the stool shown
in
Figure 1
, we secured all joints using water-based wood glue
(polyvinyl acetate). We also fastened each leg horizontally to the
base, using one screw per leg, and secured the cap vertically to the
legs, again using one screw per leg. Each screw was counterbored
and concealed with a plug.
The diameter and thickness of your piano stool seat should be
suitably sized to support the weight of the intended user. Mark the
exact center of the under side of your wooden seat with a pencil or
scribe. Draw a 4

diameter circle around the center point. Align
the seat base with the circle.
Mark and drill pilot holes, then secure the seat base and threaded
rod assembly to the underside of the seat with four #12 fl at-head
wood screws.
Glue the nut into the hole in the leg assembly with high-strength
slow-cure epoxy. Mark and drill pilot holes, then secure the nut to
the leg assembly with four #6 fl at-head wood screws.
Apply desired fi nish.
Insert the threaded rod into the nut in the leg assembly. Turn the
seat counterclockwise to raise it and clockwise to lower it.
