These plans are based upon several designs used by scouts
in our council. Some people call this a scissors chair. The chair
is composed to two pieces: the seat and the back. The two pieces
slip together and require no fasteners when used. When carried
the seat stows between the sides of the back for a very compact
package.
Note: the legs are cut out of larger pieces so they can be
curved.
All pieces are cut from a strong hardwood like oak. The Seat
Legs and Back Legs are cut from these pieces to formed curved
pieces. The Seat Leg is 2" wide. The Back Legs are 2.5"
wide except for regions that taper to 3" wide to form 1/2"
backstops for seat supports. See the seat
support detail.
If a softwood or plywood is used it is best to increase thickness
of the legs from .75" to 1" and increase the thickness
of the slats from 3/8" to 1/2". All parts are glued
with water-proof glue and fastened with 4d galvanized finish nails
or rust resistant screws.
The slats for the back and seat are 3/8" (actual dimension)
material mounted on 2" centers.
The other pieces are 3/4" (actual dimension) material.
The back has 1/2 inch notches as shown in seat
support detail to back up the two seat supports.
Sand all pieces to prevent splinters.
Use rust-resistant screws and water-proof glue.
Use water-proof glue and screws to fasten the seat supports
and spreaders to the legs.
Use water-proof glue and 4d galvanized finish nails to fasten
the slats in place.
Finish with a nontoxic penetrating exterior finish.
For a lighter version:
Seat Legs(2) - 3/4"x4.5"x33.75" - 10.5"
apart on outside to outside.
Back Legs(2) - 3/4"x6"x37.75" - 11" apart
inside to inside
Back Slats(11) - 3/8"x1.25"x15" - spaced on
2" centers
Seat Slats(7) - 3/8"x1.5"x15" - spaced on
2" centers
Seat Supports(2) - .75"x1.5"x14"
Seat Spreader(1) - .75"x1.5"x9"
Back Spreader(1) - .75"x1.5"x11"
* Thanks to Larry Elterman for finding an error in the radii previously specified to cut the legs. Previous plans had radii that were 8.8" longer. They worked but were slightly inconsistent with the other stated dimensions.
