 the middle support centrally in the frame.

 pair with the four 2" x 4" cross and brace pieces. 



First nail in position the two crosspieces on one side of a 

 pair of legs, then insert and nail securely to this pair of cross- 

 pieces the two leg frame braces. Now nail on the two re- 

 maining crosspieces, both to the legs and the braces. Finally, 

 nail on the 6", 2" x 4" block lengthwise of the bunk in the 

 center of the lower crosspieces, allowing it to rest 1" on each 

 crosspiece. 



2) Construct the frame of the box from 1-1/2" x 10" or 2" x 

 10" stock. Bore holes to secure the sides to the end pieces. 

 Note that the end boards of frame rest on floor boards.
