Wind Generator Mount (on a budget)

Wind Generator Mount on a budget “option”: Sharing a relatively inexpensive and simple way to mount a wind generator (or any other mast device). I contemplated this endeavor for while – couldn’t stomach the costs of a pre-fab or engineered mounting options ($700.00 or more)! We put our Marine Kenetics 450 on our aluminum mizzen mast using the following materials for a total cost of $ 182.97 (plus respective shipping of materials) and about 2 hours of self-labor with a drill, 3/8”tap, an allen wrench and a box-head wrench. The rig supports my weight (200 lbs) and does not vibrate. Picture included of the finished mount on the mizzen mast with the Wind Generator installed.


1.5" NOM. (1.9" OD X 0.1" WALL X 1.7" ID) ALUMINUM 6101-T61 EXTRUDED PIPE SCHEDULE 40 from company will cut to your specified length but the tube is easily cut with a skill-saw. I used 4 x 4ft lengths for the mount legs (trimming the primary and stalk legs to 32” for my specific blade span).

Aluminum fittings (1.5” for hand railing) from – These fittings have allen-head set screws to hold the tubing (I notched the tube ends for each contact point:
- #3-8 90 Degree Elbow - 1-1/2in (2 ea) …………….. $ 15.26 ea
- #11-8 Side Outlet Tee - 1-1/2in (1 ea)…..............$ 20.58 ea
- #47-8 Rectangular Base Flange - 1-1/2in (1 ea) ..$ 14.63 ea
- #41-8 Adjustable Flange - 1-1/2in (2 ea) ………... $ 19.16 ea

Bolts/washers from Lowes:
- 3/8 x 1 ˝(L) Stainless Hex Head Bolt (course thread) (10 ea)… $ 1.12 ea
- 3/8 stainless washers (10 ea)… $ 0.30 ea

King Board (Spacer) shaped to fit forward edge of mast curve for the rectangular flange above) 2” x 4” x 3/4” (scrap on hand).

Hopefully someone will find this experiment/discovery useful? I have already seen 56 knot winds with this rig with no issues - the Marine Kenetics Generator has a hysteric brake that slows the blades above 30 knots. I am starting our TRACPHONE and TRACVISION dome mount projects using this technique.
