For softer types of rock, such as sandstone or limestone, a hole 1-inch (25 mm) diameter and 8 inches
(20 cm) deep can be drilled and an eye-bolt 5/8 inch (16 mm) in diameter cemented into it. The cement
should be mixed just thin enough to pour and poured into the hole before the bolt is installed (a straw
inserted to the bottom of the hole before pouring will help prevent a bubble from forming). This will
help to insure that the cement goes to the bottom of the hole and help prevent bubbles that may
compromise the strength of the attachment. If expansion bolts are to be used, follow the instructions
supplied with the bolts. There are several different types of expansion bolts that are installed using
different methods.
Step 6:
Assembly of Tower and Turbine
The tower is assembled laying on the ground and then lifted onto a sawhorse or large box so that
the turbine can be mounted to it.
1)
Remove pivot bolt from tower base and insert it through the pivot holes in the tower base
coupler.
2)
Install the tower base coupler onto the tower pipe so that the pivot bolt just touches the end
of the tower pipe. Torque the two pinch bolts to 45-50 ft-lb. (60-68 N-m) and withdraw
pivot bolt
3)
Lay the tower pipe on the ground and locate the base coupler into the tower base.
4)
Install the pivot bolt and nut through the base and coupler. Tighten so they are just barely
snug, not tight, against the tower base.
5)
Raise the turbine end of the tower pipe and set it on a saw horse or other supporting object.
The end of the tower should be at least 3-4 feet (1 m) off the ground. Drill holes in tower
pipe using supplied template.
A tower drilling template is included as the last page of this
manual.
6)
Install the round tower insert onto the turbine’s yaw shaft. Tighten the two set screws to 4-5
ft-lb. (5-7 N-m)
