Bobbins
The Block Rockit uses a size M bobbin, enabling you to quilt for a longer period of
time without having to change the bobbin. The bobbin winder on the Block Rockit
has its own motor so you can refill your bobbin without unthreading your machine.
For instructions on filling the bobbin and installing the bobbin case, refer to the Block
Rockit’s user manual.
A COUPLE NOTES ON FILLING
THE BOBBIN:
• If the thread is not filling as the
bobbin spins, wrap the thread
around the bobbin case a few
more times so that the thread
is tighter and will catch as the
bobbin starts to spin.
• Make sure the thread on the bobbin is wrapped very tightly. The thread should not
be loose. If it is, it will affect the tension as you quilt. When the thread is wrapped
tightly, it will be hard on the side; if it is loose, it will feel soft and move around. If the
thread is loose, make sure the bobbin winder is threaded correctly and that there
are no obstructions to the thread, and then fill it again.
