THE TENNIS COURT

The young woodworker is especially well fitted for the preparation of a

tennis court. He has learned the value of accurate measurements, and is

accustomed to make a neat and finished job. While the making of a court

seems a simple proposition, it may be a very expensive one, if help has

to be hired, and all the equipment bought ready for use.

The first step is to select the exact location, which should either be

level or practically so. Any discussion as to the merits of dirt or sod

courts must be left to the reader. The court proper is 78 × 36 feet,

the posts for the tennis net being three feet outside on either side,

and the space at the ends between the court and stop nets fifteen to

twenty feet more, making a total length of 118 feet.

The following method of laying out the court is recommended:

Make sure that the long way is exactly north and south, and drive

in the ground a wooden stake at northeast corner A (Fig. 213). At B,

directly west, drive stake 36 feet from A. A steel tape measure is by

far the best thing to use for laying out, as cord stretches and leads

to inaccuracies, and two tapes are better than one.

At the centre of each stake drive a strong nail. From B measure 78

feet south, and place a temporary stake. To insure the angle being 90

degrees, apply this test: From B along the line laid out last, measure

48 feet: slip the ring of the tape measure over the nail at A, and

measure to this new point. If the angle is 90 degrees, this diagonal

measurement should be 60 feet. If this measurement does not come right,

shift the stake C, until this oblique line is exactly 60 feet, then

lines A-B and B-C are at right angles. Having fixed this angle, again

measure from B to C, and drive stake C at 78 feet from B.

Locate stake D 78 feet from A, and 36 feet from C. A final test should

now be made by measuring the diagonals B-D and A-C. They should be

exactly alike. These corner stakes may now be driven in flush with the

surface, and they should be allowed to remain, to avoid the necessity

of doing the work all over again later in the season when the lines

become obscure. Measure in from each stake 4-1/2 feet for the alleys

and drive stakes in flush.

[Illustration: Fig. 213. The tennis court]

Next measure from stakes _A_, _B_, _C_, _D_ 18 feet along outside

lines, and again drive in stakes _a_, _b_, _c_, _d_. By passing a cord

from _a_ to _b_, and from _c_ to _d_, the service lines are laid out,

omitting alleys. Find centre of service lines, and connect points

_e_ and _f_. The net crosses the centre of court from east to west,

extending three feet beyond on each side. At these two points _x_ and

_y_, set the posts in the ground. By this method, the only stakes left

in the ground are on the outside lines, and they must be driven in so

that under no circumstances will a player stumble over them. They can

always be found after a rain storm, and new lines laid out.

The posts for the net should be seven feet long and four inches square.

Plane them off smooth, and coat the end which is to be in the ground

with creosote or coal tar.

This coating should extend three feet six inches from the bottom, and

as the post is to be three feet in the ground, this coating will extend

six inches above. Decay takes place at the point of contact with the

ground, and the creosote will prolong the life of the posts for many

years, if the wood is well seasoned. Many posts for tennis nets are not

sunk fully three feet in the ground, and consequently require guy ropes

or wires to keep them upright. The time spent in digging the holes and

tamping the dirt around posts is well spent, as the pull on them is

severe, and they must stand upright.

Six inches from the top, bore a hole 3/4 inch in diameter, east and

west. The net must be three feet high at its centre, and three feet six

inches at the posts. Pass the rope through these holes, and make fast

to a cleat. These cleats may be of iron or wood, a sketch of a wooden

cleat being shown at Fig. 215. They should be of oak or other hard

wood, put on with two strong screws through holes which have been bored

and countersunk. On the side of post toward the net, three strong screw

eyes should be put about a foot apart, the lower one six inches from

the ground. The net is to be fastened to these screw eyes to keep it in

position. When everything is ready, paint the posts two coats of dark

or bronze green.

The position of the tall poles for the back stop are shown in Fig.

213. Fifteen feet is none too far from the court for the stop net,

and twenty would be better. Purchase twelve foot four by fours, and

plane smooth, or have them dressed at the mill when ordering. This

will reduce them to 3-3/4 × 3-3/4 inches. The method of enclosing the

whole court by wire netting is seldom resorted to, unless the space

available is very limited. The method here suggested of bringing the

ends about at an angle of 45 degrees has been found very satisfactory

in stopping swift service. Locate the post holes 12 feet apart, and dig

them three feet deep. After treating the lower ends of posts for three

and a half feet with creosote or tar, place in the ground, plumb each

one while filling in, and tamp the earth about them firmly.

Strips 1 × 3 inches and 12 feet long must be used to join the posts

at the top, else the pull necessary to straighten the wire will bring

them out of plumb. These strips are to be nailed at the extreme top by

eight-penny wire nails. When the structure is finished, except for the

wire, paint with two coats of the same colour as the net posts.

The wire netting is chicken wire, inch and a half mesh, and three feet

wide. Three of these strips will cover the space from the ground to the

top. It is put on with staples nailed to the posts, stretched taut, and

the joints where the strips touch wired together at intervals of three

feet with soft iron wire.

If arranged as shown in the drawing, it will take six strips sixty feet

long by three wide for the back stop, or 1080 square feet, and will

cost $9 or $10.

Cheap cotton back stops are sold, but they are not very satisfactory,

as they tighten in damp and sag in dry weather. For a permanent court

belonging to a club the galvanized wire is well worth the difference in

cost.

The size of the mesh is important, because although a tennis ball is

2-1/2 inches in diameter, when driven hard it frequently goes through

two-inch mesh.

There are many opportunities about the tennis court for the young

woodworker to show his skill. Camp stools, settees, benches either

plain or rustic, a chest to keep racquets and balls, fitted with a

strong padlock, shelters for the spectators or club members, and even a

small club house are among the possibilities.

Permanent structures, such as shelters and heavy benches, should

generally be on the west side of the court, as spectators are usually

present after the sun has passed the meridian, and it will then be at

their back.
