BEFORE YOU BEGIN
■Please read through the directions before beginning to
assemble your loom.
■Unpack the loom parts carefully. Do not throw away
the carton or any of the packing material until you have
checked to see that all of the parts and hardware have been
received
■All hardware is sized in inches. Illustrations of the vari-
ous hardware and an inch scale are provided to aid you in
determining the correct piece of hardware to use.
■Before starting the assembly, read the instructions com-
pletely and familiarize yourself with the drawings and parts.
■Follow the exact order of assembly. Take care and work
slowly. If you have someone to help you the assembly will
be easier.
■The wood parts have a removable label on them to iden-
tify each part. We recommend that you leave the labels in
place until the loom is fully assembled.
■When you nish assembling the Wolf loom, go back over
all of the screws and make sure they are tight. It is a good
idea to re-tighten the screws every few months. Remember
not to tighten those screws and bolts which are supposed
to allow their parts to pivot freely.
■All wooden parts of the loom have been nely sanded
and nished with a hand-rubbed Danish oil. From time to
time you may wish to apply more nish to the loom. Use a
Danish oil (tung oil and polyurethane mixture) and hand
rub the wood with a soft, lint-free cloth. Be sure to follow all
the manufacturer’s instructions.

brace. Place two washers on each of the rods. (Figure 11-A)
4-Shaft Looms: Place a #1 jack assembly on the pivot
rods. Place a 3/8" washer on each rod, followed by the
second #1 jack assembly. Continue with another washer
on each rod, a #3 jack assembly, another washer, and the
second #3 jack assembly. Finish by placing two more 3/8"
washers on each rod. (Figure 11-B & 11-C)
8-Shaft looms: Place a #1 jack assembly on the rods. Place
a 3/8" washer on each rod, followed by a second #1 jack
assembly. Continue in the following order: a washer on
each rod, a #2 jack assembly, a washer, the second #2 jack
assembly, and a washer. Continue with a #3 jack assembly,

Parts: 2 – 1/4" x 4-1/2" carriage bolts for 4-shaft or 2 – 1/4"
x 7" carriage bolts for 8-shaft; 2 – 1/4" lock nuts.
Push the jacks down in the center and insert the carriage
bolts (4-1/2" for 4-shaft, 7" for 8-shaft) through holes in
the front castle cross brace and on through the holes in
the rear castle cross braces. Align the square part of the
carriage bolts in the square holes and tap them rmly into
the holes. Put a washer on each bolt and secure with a 1/4"
lock nut. Do not tighten the lock nut all the way. The wash-
er should remain loose.

13. Install heddles on the shafts.
Parts:
For 4-shaft looms: 4 shafts, 8 heddle bars, 400 heddles.
For 8-shaft looms: 8 shafts, 16 heddle bars, 800 heddles.
Note: The heddle bar hooks in each shaft are slightly
o-center. The hooks should all be lined up when the shafts
are installed in the loom.
Lay a shaft on a at surface. Push up on the slide lock on
the heddle bar hook and pull the heddle bar out of the
hook. Release the slide lock. Flex the heddle bars enough
to remove one end from the slot in the side of the shaft
frame. Remove the bars from the frame.
Lay the heddle bars next to the heddles. Carefully slide a
group of heddles onto the heddle bars. Keep the heddles
loosely tied until the heddle bars are installed in the shaft
frame. Be sure to keep the heddles oriented in the same
direction for easier threading.
Replace the heddle bars in the shaft frame. Insert one end
of each heddle bar in the slot in the frame. Flex the heddle
bar and insert the other end into its slot. Divide the heddles
approximately in half and push them to either end of the
heddle bar. Push up on the slide lock and place the heddle
bar back on the hooks. Put the shaft back in the loom, and
secure the jack pin with the hex nut.
Repeat for the other shafts.

end. Slip the threaded rod through the hole in the right
inside leg as far as it will go. Fit the pin in the other end
into the stopped hole (does not go all the way through) in
the left inside leg. You will have to gently spread the right
and left legs apart to accomplish this.
17. Install the brake barrel nut.

stalled on the right inside leg.
Put the brake bar and a 1/4" washer on the screw. Take
the loose end of the brake cable attached to the brake bar
and wrap it around the brake drum. Start at the side of
the brake drum next to the loom leg and wrap going away
from the leg to the center of the loom, making sure not to
overlap the cable. Place the loop end of the cable over the
screw. Put on another 1/4" washer and a slim 5/16” lock

from the end of the brake cord.
20. Install the brake eyebolt and brake spring.
Parts: 1 – eyebolt, 1 – brake spring, 1 – 3/16" washer
21. Attach the brake spring to the brake bar. Insert the eye-
bolt through a 3/16" washer, through the hole in the long
barrel nut, and screw it into the spring.
Tighten the eyebolt until you can’t turn the warp beam
away from you when you twist the beam with both hands.
When you hold the brake release pedal down, the warp
beam should turn freely in either direction.
By tightening or loosening the eye bolt, you can increase or
decrease the tension on the friction brake. There should be
small gaps between the coils of the brake spring once the
proper tension is reached.

on the threaded shaft extending through the leg from the
brake end of the warp beam. The wood crank handle faces
away from the loom. Secure with the 3/8" cap nut. Tighten
the nut by placing the handle over it and turning clockwise.
To engage the crank for turning the warp beam, pull the
hexagonal hole in the crank onto the cap nut. While weav-
ing, the crank should be pushed off the cap nut.

For 8-shaft looms: 80 tie-ups
Push the loop end of a tie-up through each hole in the
lamms. Put the button end of the tie-up through the loop
and pull tight. To attach a shaft to a treadle, slide the button
end of the tie-up into the slot in the treadle. Make sure the
tie-up hangs straight down to the treadle.

Parts: 2 – apron bars, 10 – Texsolv apron cords
Insert one end of a cord through a hole in the cloth beam
and pull the cord through. Then insert the other end
through the second hole in the end of the cord that you just
put through the beam. Pull rmly on the cord to tighten
(A). Repeat across the cloth beam and the warp beam.
To attach the apron bar to the apron cords, take a pinch
of the cord about 4" from the end (B). Insert the pinched
cord through the second hole in the cord. Pull on the
pinched cord until a new loop forms that is large enough
for the apron bar to slip through (C). Slide the apron bar
through the loop (D) and pull tight. Repeat until all cords
are attached to the apron bar. Attach the other apron bar to
its beam in the same way.

FOLDING THE LOOM
■To prevent treadles from dragging on the oor when the
loom is folded, attach every treadle to at least one tie-up
cord. Loosen the two black fold knobs one full turn and pull
them up to start folding the loom.
■With one hand on the rear beam and one hand on the
front beam, pull the loom together as far as it will go.
■Tighten the knobs. Push the slide lock bars in towards
the front of the loom.
UNFOLDING THE LOOM
■Slightly loosen the two black fold knobs on both sides of
the loom. Generally, a single turn will do.
Note: Loosening the knobs all the way or removing them can
cause the loom to collapse which could result in injury.
■Stand at the side of the loom. Hold the front and rear
beams together slightly, and pull the slide lock bars out
toward the back of the loom.
■Continue holding onto the front and rear beams and allow
the loom to unfold all the way. If there is a warp on the loom,
step on the brake release pedal while unfolding the loom to
loosen the warp.
■When the loom is all the way down in the open position,
push the fold knobs to the bottom of the slots and tighten
them.
