RAME
X-Frame sides:
1)
2)
Note:
The Cloth Beam Bracket is on the inside of the frame.
3)
4)
For the left side you will need legs A and B. If you are assembling
the frame for the two-beam version, use legs B and E. Fit the legs
together at the notch in the center
Slide a 2-1/2” carriage bolt from the outside through the center
hole at the crossing of the legs.
Slide a Center Brace onto the bolt. Install a washer and wing nut,
and tighten to ‘finger tight’ condition.
Repeat this process for the remaining four holes using the 2 1/2”
carriage bolts, washers and wing nuts to fully secure the Center
Brace to the legs.

IMPORTANT:
The Cross Brace is plywood and should not be confused with the solid wood
Separation Beam.

3)
The X-Frame should now stand without support.
Attach the Cross Brace to the inside of the Right Side and secure
with black thumbscrew (long) from the outside of the leg.
Stand the Left and Right Sides approximately 17” apart (for the 16”
WDL) or 25” apart (for the 24” WDL) with Center Braces facing
each other.
Secure the Cross Brace to the Left Side with a black thumbscrew
(long) from the outside of the leg.

Install the IDU
1)
Set the IDU onto the Center Braces inside the X-Frame so that the
Dobby is on the right side of the loom.
Figure 24 - WDL with IDU
2)
Note:
As before, the bolts are inserted from the outside through the X-Frame and
through the IDU.
Secure the IDU to the X-Frame using the (4) 2” carriage bolts,
washers and wing nuts.
3)
NOTE:
A light tap with a hammer on the end of the bolt may be used to help seat the
bolt.
Interchangeable Design Unit (IDU) Page | 15
Tighten all the wing nuts so that the square part of the carriage bolt
head sinks into the outside of the X-Frame.
WDL Assembly Workshop Dobby Loom User’s Manual
HANGING THE HARNESSES ON THE IDU
Review the lay of the harness cables to make sure that they are arranged on
their proper pulleys. Cable ends should hang freely over the pulleys and
down inside the IDU.
Heddles:
You have been supplied with 25 heddles per harness plus 200 extra. You can
purchase additional heddles from AVL. Heddles are shipped in bundles of
100.
You can divide the bundle of 100 heddles into smaller bundles to place on the
harness. Without removing the original twist-ties, count out the number of
heddles you want on the harness. Place a new twist-tie around each smaller
bundle. Remove the original twist tie and cut the smaller bundles apart.
1)
Insert an Eye Hook Retainer Tube over each harness cable loop and
up above the crimped Nico. You will slide the eye hook retainer
back down over the loop once it has been hooked onto the harness
stick.
2)
Figure 25 - Eyehook cover on Harness
Lay two harness sticks flat on a table or floor with the screw eyes
facing away from each other.

3)
Slide the top harness stick through the loop at one end of a heddle
bunch, then slide the bottom harness stick through the opposite
loop of the heddle bundle.
Figure 27 - Place heddle bundle on heddle sticks

5)
Remove the ties on the bundles.
Now clip the loops of your heddles -- it is easier to cut the loops
when your harnesses are off the loom. You now have one harness.
