Modified Vertical Axis Wind Turbine (1/4" Motor Shaft)

Description

Intro ----- I Have A Motor That I Wanted To Test With Hooptey'S Vertical Axis Wind Turbine. He Was Kind Enough To Post The Sldpart'S So I Went To Work And Modified Both The Hub And The Arms. The Changes Are: + Attachment Screws Changed To 3.12Mm Locking Torx Screws (Http://Www.Mcmaster.Com/#99397A626) On Both Arms And Hub + Hub Gear Removed And Modified To Have 1/2" Shaft Instead. Shaft Locked In By 1/4"-20 X 1/4" Coarse Thumbscrew. + Rain Protection Built Into Hub, And Optional Rain Cover + Motor Mount Added ___ Testing --------- Testing Began With The Finishing Of Version 6. It Was A Massive Failure. Not Only Was Wind Not Very Strong, But I Did Not Have Blades Required (The Blinds). Instead I Cut Out Cardboard Blades. When Tested With A Leaf Blower It Became Clear That There Is A Specific Angle That Must Be Caught. The Arms Will Have To Be Changed. Another Issue Could Be I Need Gearing To Turn The Motor, But There Is So Little Force Needed It Might Not Be Needed. After A Little Research, It Would Make Sense To Do Longer Blinds, And Possibly More Arms. _____ Parts List ------------ + 3.12Mm Locking Torx Screws (Http://Www.Mcmaster.Com/#99397A626) Note: These Are What I Have On Hand, And This Might Change! + Motor: + 2€ Body Diameter X 3-3/4€ Long + 1/4€ Shaft Diameter + 140 Volt 3700 Rpm + Four (4) X 1/4"-20 X 1/4" Coarse Thumbscrew ___ Change List ----- + V7 + Rain Cover Eliminated + Second Tier Added, Held Together By 1/2" Garden Poll / Screw + Rear Motor Mount Changed Slightly + Hub Top Added.
