LOADING THREAD ON A BOBBIN
a spool of thread on the bobbin is very basic and this article will be
helpful when tying your first fly. The use of a bobbin tube threader
will make it very easy to pull the thread through the bobbin tube when
loading a new spool.

Attach the spool of thread on the bobbin.
The spool bearings are placed in the holes
on the spool of thread.
Place the bobbin spool bearings into the holes on the spool of thread.
Insert the threader into the bobbin tube tip and push completely through.

the thread through the bobbin tube. Extracting the threader will pull
the thread back through the bobbin tube with it. It almost doesn't need
Adjust the tension of the bobbin arms. You can physically bend the arms
on the bobbin. It only takes a little pressure on the bobbin arms to
increase or decrease the tension. Squeeze the bobbin arms together to
increase tension or spread them apart for less tension.
Fly Tying Bobbin Thread Tension Test
This spool of thread easily rotates on the
bobbin, but there is just enough tension
that it will hold it's own weight when
hanging in the air.
HOW MUCH TENSION SHOULD THE BOBBIN ARMS APPLY ON THE SPOOL OF THREAD
Tension can't be photographed and words are inadequate. The spring arms
on a fly tying bobbin are designed to apply tension on a spool of
thread. The proper amount of tension will let the spool of thread
rotate on the bobbin spool bearings, while still having enough tension
to prevent it from freely unraveling. If you have too much tension the
thread could break. The secret will be finding a happy middle ground,
which you will figure out with a little patience.
When using Kevlar or other high strength
thread for applications such as spinning deer hair will need more
tension to prevent the spool of thread from rotating when applying the
necessary torque. When extreme thread torque is used, instead of
adjusting the bobbin arm tension as described above, manually keep the
bobbin arms squeezed together in the palm of your hand for the required

Homemade Mono Bobbin Threader
An five inch piece of xx pound mono.
Use a razor blade to cut a grove near the
tip of the mono. The thread can then be
slipped in the grove and pulled back
through the bobbin tube.

Ram Rods used to clean Bobbin Tubes
(Standard and fine tube sizes)
BOBBIN TUBE CLEANER
using waxed thread, the wax can build up inside the bobbin tube and
should be cleaned if needed. Generally the worst problem caused by wax
build up is that it makes threading a new spool of thread is more
difficult. You can buy a ram rod designed for this purpose or use a
length of mono to push through the tube. Don't use a stiff wire that
could damage or score the inside of the tube, which could cause the
thread to break or fray.
MANUALLY THREADING A BOBBIN
An easy way to thread the bobbin is push the thread into the tube as
far as easily possible, then place your lips on the tip of the bobbin tube and suck the
thread through. It really does work, but make sure there isn't any wax
build-up or grim inside the tube or you could inhale it in the process.
Using a vacuum cleaner to thread the bobbin.
Place the vacuum nozzle up to the bobbin and it
quickly sucks the thread through the bobbin tube.
Most people think this is a funny method.
have a canister style vacuum cleaner and
when placing the nozzle to the tip of the bobbin, it quickly and
effectively sucks the thread into and through the bobbin tube. Most
people think we are crazy, but it works.
