Socket head machine screws then bolt the plywood surface to the framing members below. This affords a flush joint between sections with only the small counter-sunk, hexagonal screw breaking the surface of the panel. Lateral plywood joints are staggered.

The plywood sections are lettered on the back to indicate the exact position where each belongs and to facilitate i.nstallation of the floor. The plywood is finished with a special preparation for gymnasium floors manufactured by the Hillyard Co.

Now the management's difficulties are solved. Once the basketball game is over, the floor sections are taken up, sticked on skids and hauled to a.storage shed. It tl,en takes but a short time to smooth the ice surface in preparation for the hockey practice or league game to follow.

The use of Douglas fir plywood in the construction of portable basketball floors is not new. However, its use in this field has solved a unique problem at Philadelphia, Pa', thus adding to the long list of applications that in the aggregate prove the extreme versatility of the panel material.

The management of the Philadelphia arena, home floor of the Philadelphia Warriors professional basketball team, and ice rink for the Philadelphia Rockets hockey team, was confronted with a serious problem. A league basketball game and a hockey match were scheduled for alternate nights. This meant that once the ice had formed on the concrete floor for the hockey inatch, there wasn't time to defrost it and lay a wood floor for the basketball game the following night.

Solution of the parodox was achieved by laying a sectional floor of Exterior type Douglas fir plywood directly over the ice. This was accomplished in six hours with a crew of ?0 men.

The /a-inch panels were laid in 4 x I?-foot sections supported by l% x 4-inch joists, or battens, placed flat and 15 inches on centers parallel with the length of the panels. Plywood is secured to battens with wood screws and waterproof glue. Battens along two adjacent edges of each section extend 2 inches beyond while the battens along the opposite side are set back 2 inches.

Joining of the sections, with the plywood of one overlapping the batten of the other, is accomplished with special'anchor nuts manufactured by the South Chester Corp. oI Chester, Pa. These special serrated anchoring devices were inserted and glued into both the plywood panel and

14-Year-OldPlywood Boat

(Continued from Page 56) constructing a lightweight boat for use on various rivers on the Olympic peninsula. Particularly, the boat was intended for use where it would have to be carried in about three-quarters of a mile, and minimum weight rvas of the essence.

Today, longitudinal framing wherein plywood planking is employed without transverse ribs is favored by a number of small boat builders.

"I can safely say that I have traveled more than 1,000 miles-perhaps 2,000-up and down the streams of the llympic peninsula in this sturdy boat," Birk reports. 4 re,cord of the streams that he and his friends have fished sounds like listing of the rivers of the area: the Satsop, Wynoochee, Quinault, Chehalis, Sol Duc, Hoh and Skokomish.

In addition, the boat was used for five years on llood Canal the year around. It has traveled as far or farther in salt water, therefore, than fresh. Most of the use on the canal, of course, was with an outboard motor whereas most of the use on streams was with oars.

Birk, the olvner of a drug company bearing his name and with stores at Aberdeen and Port Angeles, announced the boat was in good condition and ready for many years of service when the plywood company "bought back" their material this summer. In fact, he took the boat out {or a final spin on the Wynoochee river before surrendering it.
