Beater height adjustment
With the David, the shed is created by shafts being pulled down.
The optimum shed has the lower half of the shed lying on the shuttle race so that your shuttle
slides smoothly over shuttle race.
As you weave and the fell line gets closer to the reed, the shed becomes smaller and the lower
half of the shed can start to lift off of the shuttle race. For optimal weaving comfort, we
recommend the distance between fell line and the reed be 18 cm
(7”) or more. After every 5 cm
(2”) of weaving, advance the warp a little further.
The warp will deflect upwards when you start weaving and the tie-up bar has not yet passed the
breast beam. At this point the shed can be a little higher above the shuttle race, decreasing the
size of your shed.
It is also important that the left and right sides of the beater are flush against the buffers on the
castle. This is mainly determined by placing the hinge hooks of the reed exactly flush and
perpendicular to the side upright.
Position of the warp in the reed when
the blocking pin is removed
When the treadle is pressed, the lower half of the
shed is on the shuttle race.
•
The hinge hooks mounted on the
lower cross bar must be exactly
level and perpendicular to the
side.
•
The locking nut must be tight.
•
The distance measured from the
flat ground must be 5 cm
(2”) to
the center of the shaft.
o
Measured from the bottom of
the cross bar, the center of
the hinge hook needs to be
8.5 cm
(3 3/8”).
5 cm from floor Or 8.5 cm from the cross bar
