(use 220# sandpaper or finer). In times of high humidity especially, the
grain at polar sides of the drum may raise and prevent the cable from
slipping.
Note:
Never, under any circumstances, should you apply wax, talc, or other
finishes to the groove. The wood here needs to be raw for the mechanism to
operate as intended.
Harness Float
Some threadings, such as Summer/Winter, call for many more ends to be
carried on one or two harnesses. In this instance, you may experience
“Harness Float”. An indication of this problem is the looseness of heddles on
a particular harness, above the warp ends, and the ends pushing against the
top of the heddle eye.
If you find that this is interfering with your looms ability to create a clean
shed, you may wish to order a few extra springs to help alleviate this
problem, mounting a second spring on the eyehooks.
On occasion you will find that one or more of your harnesses will misbehave.
That is more likely to happen with harnesses with Polyester Heddles. There
are a finite number of things that can cause these problems.

Possible Cause
How to Fix it
A.) One or more top
harness stick
collapses; it assumes
a diagonal angle and
one leg of the
harness cable from
which it is suspended
goes slack.
1.) Your heddles are
bunched together
towards the center of
the harness or on one
side only. This is a
problem because the
heddles are part of
the harness structure.
Move a few heddles to
each end of your
harness sticks; just to
the inside of the
harness wires that
connect the top and
bottom sticks. That way
your harnesses will be
balanced.
2.) The harness cable
supporting the shaft
has come out of its
pulleys at the top of
the loom.
Trace the cable back
through its pulleys in
the Harness Pulley
Support and make sure
that the cable is
properly seated. Check
