Ok, the wheel is a single drive, flyer lead - meaning that the drive band goes from the flyer whorl, around the drive wheel and ends back at the flyer whorl. When you treadle the wheel, the drive band turns the flyer.
The bobbin has a break, which is the Scotch tension. This band, which most likely looks like nylon fishing line is attached to a peg which will turn on one side and the nylon line should have either a rubber band or a spring on the loose end. There should be a hook on the side of the wheel opposite of the beg to hook the rubber band or spring to. Place the nylon line over the whorl on the end of the bobbin and tighten it by turning the peg.
You set the tension on this wheel by turning this peg...tightening it adds tension, loosening it removes tension.
Put the flyer in place and make sure you have a nice long leader on the bobbin and that the leader is attached to the bobbin tightly so it doesn't just slip around when you're trying to get started spinning.
Now, look at the main drive band - see where it fits into a groove at the top of the small wheel? The grooves in this small wheel are the flyer whorls on this particular wheel. These govern your wheel's ratios. On your wheel the ratios are: 6, 8, 11 & 14:1. The ratio tells you how many times your flyer will turn each time you treadle: one treadling turns the drive wheel one time and the drive wheel then turns the flyer X number of times. The largest diameter whorl gives you a ratio of 6 and the smallest diameter whorl will give a ratio of 14. Now, every time the flyer turns once, one twist is inserted into the fibers. So if you use your largest diameter flyer whorl (recommended for learning to spin) and you treadle once, the flyer will turn 6 times and 6 twists will go into your yarn. So...if you draft 1 inch of fibers, 6 twists will go into that 1 inch, giving you 6 twists per inch. If you draft 2 inches then 6 twists will go in and you will have 3 twists per inch. Ok, for now, just put the drive band on the largest diameter whorl
Now, thread the leader through the orifice and try treadling. Is the leader usnspinning? They often do - keep treadling and it will spin up again. Check to see if the leader is slipping on the bobbin.
Most importantly - is the leader taking up on the bobbin? If not, then your yarn will also not wind on. If there is no take up, then the tension is too loose. Turn the peg for the Scotch tension to tighten it - just a bit and try again until you get some take up. Too much take up yanking the fibers out of your hands? Then turn the peg to loosen the tension - again, just a bit. Scotch tension has quite a fine adjustment and you develop a feel for it. You will know when you have the tension set just right when the yarn winds onto the bobbin BUT you can still gently pull it back off of the bobbin through the orifice. As the bobbin fills, the tension will change and you will most likely have to make minor tension adjustments as you spin.
I hope this helps. Keep us posted on how you're doing.
