    Oh well. You'll have this sometimes.

    40 volt Ametek. Hand carved wooden blade. Notice how the hail stones took the paint off.

    It's about a 2 1/2 inch pipe in 3 1/2 feet of concrete but the concrete level is 6 inches below the surface so I'd have the option of cutting it off with a reciprocating saw below the "grass level". That just might be an option.LOL!

    Is that a ladder along side of the 2 1/2" Pipe?
    Not really a triangle tower.
    Any Guy Wires ?
    How high 25' ?
    60" Rotor ?

    Did you use Sched 40 or Sched 80 Pipe ?
    Hope you got some awesome AMPS before it bent.

    Is that your new patent pending furling method?

    The ladder is tied to the pole for servicing. It just happened to be up at the time.

    17feet high.

    No guy wires which would have saved it but I went for "Sex Appeal". Got 2 years out of it.

    4 foot blade.

    Hi Andy,

    A 21' 2-1/2" Sch 40 (or 80) pipe tilt-up would be a fairly easy fix. I have two 6' long pieces of 3"x3" angle impeded about 36" into a concrete base and have two 5/8" diameter thru-bolts that go through angle and pipe to secure it. I pull the top bolt out and use a come-along to raise/ lower it when needed. The two pieces of angle form a channel so the pole can only tilt down one direction, a gin-pole is needed but can be incorporated into the angle or placed perpendicular to the base of the pole. (various options there)

    Just a thought,

    Dave
