Do you get these HDPE cutting boards wholesale? I went to buy one and it was $10 for a 8"x12" piece.

I still have to fabricate the frame stand and and add shaft collars to the gears. It's looking like it will work.

I may have to add a brace to keep the gears perpendicular to the PMA shaft.

Hi, I completed the pedal and gear frame assembly. I have to cut more bearing housing and gear hubs, then I can complete assemble to see if it will work.

Hi, the larger blades are adding a lot of drag and has reduced the RPM . I can increase the gear ratio at the transmission and modify the top blades for less drag. The design shows promise when used with a F&P. I just have to find the correct combination of all the parameters.

You sure you don't want to donate that to an art museum? Damn that's nice looking.

Peak wind speed 11 MPH, Average wind speed 6 MPH.

The top blades are acting as a speed control that limit the VAWT's RPM during high winds.

I will have to reduce the drag on the top set of blades. I  may be able to use a stock F&P stator with this blade configuration. More testing is required.

square hole in the pedal cranks is now a round hole, I still have to drill and thread the holes for the set screws

Hi, yes someone could, this is easier for me. I do not have to weld and I have poor metal crafting skills.
