That is the question we tackled in one of our most recent Ask The Woolery videos. The drive system is what determines take-up or how fast the fiber is pulled from your hands. Each drive system is made of the same parts—flyer, bobbin, mother-of-all, drive wheel, drive band, whorl (or pulley), and uprights. How these parts interact determines the kind of drive system.
Scotch tension a “single drive” system, the drive band travels around the drive wheel and the flyer whorl. The brake band travels over the bobbin whorl. You can change the take-up by adjusting the brake band. Many folks like the minute control you get with this system. You have to make micro-adjustments as you spin, particularly as the bobbin fills.
Irish tension or bobbin lead is another single-drive system. The drive band travels over the drive wheel and the bobbin flange and the break band is on the flyer. This create a very aggressive take-up that is great for plying and bulky yarns.
Double drive, as you may gather by now, is a double-drive system. The drive band travels around both the bobbin and the whorl. Take-up is adjusted by changing the tension on the drive band. Many spinners like the consistency of this system. It excels at making medium-weight and soft spun yarns.
There you have it in a nut shell. Watch the video to see these systems in action.
