unfinished portions. Strips may extend across bottom of back board and forward to door sill (DS). Entire flooring is now complete. Extensive detail has been given for clearness of directions. Actual work is exceedingly simple and easy.
DOOR CONSTRUCTION: Door frame is made of material 1x11⁄2, used flat for 1-inch thickness of doors. Corners of the frame are joined as per Fig. I. Small finishing nails are suitable for corner joints, but small corrugated fasteners (C) across door frame joints may be used for reinforcement. Frame should have about 1⁄4-inch clearance on all 4 sides when tried in doorway before hdw. ci. covering is installed, since in this door design the hdw. cl. is to pass around the edges of the door. In mounting hinges, if a small drill is at hand, it is well to drill holes for screws to avoid splitting out the screw holes in door frames, etc.
OPTIONAL: Door construction same as in pen designs in Chaps. 22 and 23 may be used if desired. In these pens, doors fit doorways closely, and hdw. cl. does not come around door edges.
