Vintage Windmill and Wind Generator Forum

Thanks Paul, for the pdf on the Trade Fair Event Schedule. I did notice an auction for 1:00 pm in the parking lot on Saturday.

Challenge 27

Have received the trade fair packet; but unlike previous years there was no list of events or a schedule.

I am hoping there will be a "end of the trade fair" auction like there has been in years past. I want to bring a pickup truck load of parts &c; much of it will almost certainly end up in such ...

Perhaps the first windmill to utilize the "off-center wheel" concept was the Perkins Solid Wheel. Perkins patented his windmill in 1869. Just when the first ones were made is uncertain. In 1873 he and his brother founded the "Perkins Windmill and Axe Company." But Perkins had been making windmills ...

There is a feature assures that this is a Challenge 27 wheel.

Note the 2 beads on the outer half of each blade that are at a right angle to the wheel rims. Due to the horizontal positioning of the wheel, in this instance they will appear to be "under" the wheel clips. I do not know of any other ...

I should consider myself fortunate. While still in high school (way, way back in the 1970's) I went through Atwood and saw that windmill.

It had been restored by a man with the first name of Anton. I am not sure of how to spell his last name correctly. It was pronounced something like "Dozoba ...

"Burdick was 600 miles West, doubt he would have put them up. I also don't think he began until the 20's maybe."

Quite correct. Burdick didn't begin until the 20's.

Burdick was quite the photographer and T. Lindsay Baker published a book titled Blades in the Sky Windmilling through the eyes of B ...

Your are a very fortunate windmiller, Windcatcher530 Dan. A NOS Challenge 27 still in the crate!

Honest confession is good for the soul. What size is your C-27?

I believe the blades or "wheel slats" (as the Challenge company referred to them) were the same for all three. The 8 and 9 footers had 18 blades, the 10 footer had 24. All three had six wheel sections.

The 9 footer was essentially an 8 foot wheel stretched out to 9 nine feet wheel diameter; perhaps ...

Referring to my trusty 1941 Challenge catalog, which includes a parts list, the parts number for the "nosepiece"(as the Challenge company referred to it) was 4056 for the 8 and 9 foot size; and 4054 for the 10 foot size. So the nosepieces for the 8 and 10 foot size weren't the same.

Challenge did ...

Sorry for you loss.

May God be with you.
