Double drive ratios:
The ratio with the drive belt
around the large flyer pulley
is approx. 7.5:1.
To spin a finer yarn while
treadling at the same
speed, move the drive belt
to one of the smaller pulleys
- either 9.5:1 or 13:1.
Bobbin lead:
Place both loops of the
drive belt around the
small bobbin pulley and
re-tension it. Then place
the brake band over the
large flyer pulley. This
ratio is approx. 16:1.
Adjust the brake band
tension so the springs
only just begin to stretch.
Single drive:
Place both loops of the
drive belt around the
large flyer pulley and the
brake band over either
bobbin pulley. Adjust the
brake band tension so the
springs only just begin to
stretch.
To spin a finer yarn move
both loops of the drive
belt onto the small flyer
pulley and re-tension it.
