This is how I was using the drive band and the scottish tension - in fact I had it on the bobbin, the whorl AND the Scottish tension on once - impossible.
I found Spindlicity from a link on Abbys Yarns, and on this page there are two videos which have helped me to spin the way I want to now.
Just one second in the first video made the penny drop for me about ratios. Reading about ratios did not enthral me and I found it hard to understand, now I know which whorl to use and to put the drive band on my bobbin as well. I had been struggling with the Haldane wheel I have using it as a single drive wheel. I had the double length drive band on the small groove on the whorl and used the Scottish tension. So I was spinning very fast and found it impossible to spin big yarn and pronouced thick and thin yarn.
The second video and the photographed instructions for spindle spinning down fibres, like camel and yak and I suppose my Akita dog. I had had a go at spinning my dog's fibre and the air was blue with me swearing at the wheel. Now I know that it is better to use long draw and because the fibres are so short and have a lot of air between them it is actually better to squash up the fibres and roll them in your hands before you spin.
I spent more than an hour hand carding some of the Cheviot fleece I had washed myself, with a royal blue merino roving, mainly to try and soften the Cheviot a little, and for interest. I made about a dozen large rolags of fibre. When I changed the ratios on my wheel so that I could attempt spinning 'big' again, I used all the rolags in about 15 minutes - I need a drum carder NOW !!
