I was silly and chose this antique wheel on impulse for a Christmas present. The person I bought it from was using it for decoration, but the person SHE bought it from used to spin with it.
Its all moving and I have managed to get some yarn out of it, but it only seems to have one ratio - 6:1 and im having trouble keeping a steady speed.
So here are pics with what I think is wrong with it. Please could someone tell me whats missing and give me some tips?
Thanks

Nothing much wrong with this. Its a castle style wheel....

In this one, i'm wondering if the hole for the crank is meant to be this shape? Its a little loose and it makes a hell of a noise, and sometimes falls off mid spin. Should it be just round? I can easily fix it if thats the case.

It only came with one drive band, wrapped like this around the wheel and the flyer whorl. But as you can see, the bobbin has a groove too. Should the drive band wrap around this too? Is this for a brake band? If so, what else would the brake be attached to?
Also, the bobbins are tiny. 3in across. Does anyone know of another wheel that has these, or will I have to make them myself? (I'm pretty good at woodwork) It only came with one, or at least thats all the seller could find. This is what I've managed to make, but I've put it aside for a while as i'm sure it is meant to work better than it is.

Any input would be well received.
Thanks
