To Make a Mission Screen
ALL the tools necessary for making a . screen are a hammer, a few fine nails, a saw, plane, gimlet, rule and glue pot. The necessary material may be found at most sash and door factories or plan- ing mills free of cost. They are : Four pieces like A, 2 like B and 6 like C in 1" boards. If possible obtain pieces of the same wood, ash or elm being preferred.
If no work bench is available, nail a ^" piece to the floor and by using this to keep the stick from sliding, plane sides smooth and sandpaper. Then take two pieces of A and the two B's and at a and b bore holes for the casters. Cut in all the A's and B's Y^' cuts at m, n, p, q. Then with knife or chisel break out the pieces and square the holes. Cut out the pieces in the C's at r and s, and smooth the openings. Next procure 2 pairs of suitable hinges and fasten one pair on each of the A's which have not the caster holes. Place the hinges on the face shown in the cut. When this is done, varnish or stain all the pieces thoroughly.
When the stain has dried, the pieces are ready to assemble. Take 4 of the C's and 4 of the A's and glue firmly ; a few fine nails may be used, care being taken that the wood does not split. Then assemble the 2 B's and the remaining C's. When glue has set, put up the frame, put in the castors and stain or varnish again. When this is dry, a suitable cloth may be attached to this frame. This screen is cheaply made and if carefully built will serve the purpose of an expensive screen. One thing in which care must be taken
