Step 5: Tower Base Assembly
To assemble the base, a 6 foot long piece of tower tubing is positioned half way through the base tee as
shown in the drawing below and the set screw tightened to hold it in position (use the 5/16 inch allen
wrench included with your turbine).
The base “T” should now be placed on the position chosen for the base of the tower, perpendicular to
the direction that the tower will be raised. Once assembled, the tower will pivot on the base tube as it
is raised into position.
Depending on the nature of the soil at the site, the ground staples (included) should be driven or
cemented into the ground so that the base tube is captured. If cement pads are to be used, the base
tube can be supported at its ends and used to hold the staples while the cement is setting. If the
base is to be on solid hard rock, expansion bolts and chain should be used in place of the staples.
For softer rock the staples can be cut shorter and cemented into holes drilled in the rock.
Step 6: Assembly of Tower and Turbine
Note: If larger than 6 gauge electrical wire is to be used, it may be necessary to cut or file a
relief in the bottom of the lower tower pipe section for increased wire clearance. This should be
done before proceeding. Make sure that the inside edge of the tower pipe is smooth and free of
burrs that could damage the electrical wires (see figure on page 13).
