Bore a 3/4-in. hole in each end to a depth of 6 in. Place a
3/4-in. bolt in each hole, the bolt being long enough to protrude
2 in. beyond the end of the wood. Short pieces of wood are nailed
on the center pole about 2 ft. from the end that is to be used for
the bottom. This should form a hub on which to place the inner
ends of the extending spokes that hold the platform. The spokes
are made from twelve pieces of 2 by 4-in. material 12 ft. long.
Usually a wheel can be found in a scrap pile suitable to place on
the pin that is in the top end of the center pole. The wheel
should be open

or have spokes. This wheel is used to attach wires for guying. The
bottom pin in the center pole is placed in a hole that is bored
into a block of wood about 12-in. square and 3 or 4 in. thick. A
piece of sheet metal should be drilled and placed on the pin
between the block and end of the pole to make a smooth bearing.
The center pole is now placed in position and guyed with six wires
that are about 35 ft. long. Stakes are driven into the ground and
the wires fastened to them and to the wheel at the top end of the
pole.
