YAW AXIS

[Breezee]

Is it okay to use a spindle and hub off a automobile for your yaw axis? I was wondering if it would turn to freely? I am putting a gravity tail on it for side furling. I have noticed everyone using pipe inside of pipe for this.

It will work as long as you can keep the water out.

The frictional damping of a simple pipe bearing is an advantage especially in turbulent winds. For a free turning bearing you may have to make the tail a bit longer to get some extra damping.

The commercial machines all seem to use some sort of bearing arrangement.

Well there you have. Sometimes computers work and for me most the time the don't?

Its funny I do the same thing every time. But my picture post only work 1 out of 3 maybe.

I try one more if it don't work then bill Ga$%^(%#@%^&S can shove this puter up his $%&^.  JK TAS Jerry

Its just a conspiracy against you Jerry....

(just kidding)

You should be able to post as many pics as you want in a comment.  If you ever want to try to figure it out though... try this:

go over a page that works... and click the right button on your mouse, and select "veiw source"

and then go to one that doesnt work.. and do the same thing.  Youll see the picture address is inside some html tags, there is something wrong, or missing about yours there.  I should've check so I could make it clear, but I allready deleted the defective ones... so perhaps next time well try.

I guess Id have to agree with Flux...

some "engineer types" I've met get really bothered by pipe over pipe.

But its never going to sieze... it's probably never going to wear out (if it does itll take a LONG time)

and it provides nice resistance to yawing which is nice... very fast yaws are hard on things, I think a bit of stiffness in the yaw bearing provides some stability.  It may also be of advantage when we have the "dangling" wire down the tower, to help prevent it from twisting up too fast.  pipe over pipe works great

I wouldnt complicate things.

But if you like to complicate things and want to spend the xtra money and all - I suspect a wheel spindle would work fine. Of course, youd almost have to use a tight bearing if you chose to incoorporate slip rings...

My bet, is any bearing you choose though will fail before pipe over pipe fails.

Dan;

I think it is the AOL browser or at least at one time that was my diagnosis of jerry having trouble with pictures and perhaps the intro limit problem too. Nothing any of us can do to fix that.
