    new life for old paint sample tubing

    My wife snagged these at an LBS that had stopped carrying Cannondale. I heard all they were good for in the shop was falling over making a racket and a mess. The thing turns on the axle so I'm thinking about adding some prop wings for the wind to blow ... anyway ...

    She's a keeper !

    To make it rotate, take a look at how anemometers works.

    Thanks for that tip, it's just in time because I just tried some cardboard prototype props, and it probably turns less with those than it did without them.

    Tried adding saddles and puttng it on a fixed base but it wouldn't spin. Either the saddles don't catch enough air or the tubing weighs too much.

    Thanks for the use of your forum space!

    You have the angle of the saddles wrong, that's why it won't work.

    The saddles must be turned, so that they are pointing towards the center.
    Like they are now, you'll need a hurricane to make them work.

    Tie fishing line to the anchor at the top end of the tubes where the chain is. Drop it down through, and tie a flat object of some kind (I'm thinking rear wheel dork discs would be PERFECT) to the end that comes out at the bottom. A few nuts tied along the length of it to whack the insides, and you have a whole mess of noise making potential.

    If I understand that you mean the nose of the saddle should be pointed directly at the hub so the saddle is at 90* to the center of the hub?

    If so, I started with the rods welded at 90* and tried that. No joy that way either.

    Attachment is the image I based it on - I welded the arms in the opposite direction from that, but I think that just means it will turn opposite of the DIY anemometer shown.

    Good idea about putting the dingers inside, I really didn't want something hanging from the center of the wheel, banging up the outside painted part of the tubes.

    The way you started out was right.
    If you take a closer look at the DIY anemometer, it closely resembles that, as the hub the spoons are attached to, is rather small.

    I'd guess your next step is to service your hub, as it is not running smooth enough then, or you need bigger saddles
