A bicycle headset for a Yaw bearing ?
« on: March 12, 2006, 04:02:26 AM »
   Okay here's the picture so far....

It was doing about 140 rpm in a 6mph wind (we

tend to call anything over 3mph here in

Conneaut a wind) If you can have a cigarette

dangling in your mouth without the smoke drifting

up into your nose...that's at least a breeze,

LOL !





Yeah that's it the front fork...now see how they

curve? Now if I curve it just a little more

it'll be offset similar to a regular furling

system....

Facing the mill the blades turn clockwise ...

so the offset would be to the right ?

  Now I guess the angle for the tail will not

be quite so simple...anyone got suggestions ?

  Greatly appreciated....

   ...Oh I guess I have it curving the wrong

way at the moment...so if this is wrong (it's

going clockwise in this view)..I just have to

switch tines ??

How about attatching a set of handlebars in the other end of the forks?


You could then weld your tail onto one of the bars to create the offset for it.


A set of mountain bike handlebars would be pretty strong.


I'm liking your thinking.  But the wife is getting worried about her mountain bike that's sitting outside.  She mentioned that mine is a lot more beat up than her fairly new one!!   LOL


(Oh, and she said my son's bike is out of the question!!)


Gawd, she knows me too well!!


Now that I've got my tax return and a little "disposable" cash (read: what the wife hasn't gotten a hold of yet), I'm looking to start building my first genny.  Browsing the Forcefield site I saw those 3/4" X 1/4" disk magnets and got me thinking about a small one to start with.......


Hel, I'm still working on my "redneck outdoor woodburning stove"!!  :)

Hi,


your picture looks nice.


Instead of the front fork

you can fix a part of

the frame there to get

the platform for the

wind rotor (to get easily

the offset needed)?


- Hannu


P.S.


I'm not married, so I can go

around with the tools to

break even ladies' bicycles.

  Here's how I did it, with all bike bike parts. Furl, yaw and offset.

Just now hit me. Didn't see it earlier.

The fork being used is offset from the head already.

Bend the unused fork around to the 'proper' angle,

mount the tail to the unused fork.


Or cut, flip, weld it.

Then it'll be reversed, other side from the axle.

Ghurd,Hannu,Nanotech,and Professor:

  You guys have been a really big help, my first

one will be as Ghurd suggested,since I'm already

there, next will be Nanotech's, all I would have

to do there would be to put the fork the right

way stick the handlebar assembly in, wouldn't

even have to cut the fork for this one, the

Professor's was a little more involved but

ingenious....and Hannu I can imagine you've seen

more of this stuff using bicycle parts than the

rest of us combined, but we don't break bicycles

....We modify them...right?....LOL !

I just did something like this over the weekend, I have it setup so the windmill itself is the furl, but the bicycle fork does not have enough lever arm for the miniscule amount of wind I get, so I stuck an inverted frame up as a pivot with the windmill in the fork tube(pivot at the seat post), now just have to get some bearings to it...
