Aligning Metal and Wire Heddles for Efficient Threading

I never thought too much about my heddles on my looms until I started restoring a couple looms and again a few days ago while helping a friend thread a loom. There is a definite difference in how to install them depending on if they will be threaded left handed or right handed. 

It pays to check the loom before threading so any changes can be made ahead of time.

These are an example of typical wire heddles.  Enlarge the photo to see the direction of the angle of the eye.  These are installed for right handed threading.  The eye slants from front to back, left to right.  Because of the direction of the slant, it is more difficult to thread by someone who is left handed.
By flipping the heddle end to end, you can change the threading direction to left handed. The angle slants in the opposite direction (front to back, right to left).

It pays to watch which direction the eye is facing when putting heddles on the loom. When I was helping a friend thread a new-to-her loom, one shaft had the heddles backwards with a left handed angle, which made it awkward for threading and slowed the process. I have noticed it on a couple of my looms also. I think it is worth the time it takes to fix them and will do that the next time the looms are empty.

 Here are a few heddles from some of my looms.  From the left, the first one is an inserted eye heddle.  The second is a wire heddle.  The third is a stamped metal heddle and the one on the right is a Leclerc repair heddle.  They all have some differences to distinguish front and back or right and left handed.  They don't come designated right or left.  That is determined by how they are installed.
The inserted eye heddle has a slight bend near the top and bottom.  Flipping it side to side will not change the eye angle.  To change from right to left, the heddle must be flipped end to end.  The bends on the ends won't really help much for determining which end is up, so the best thing is to hang one end loop on something stiff and see which way the eye angles.  The chenille wire works well because the heddles don't slip off the wire.
The other wire heddle is like the inserted eye heddle above, with nothing to distinguish the top from the bottom.  Hang them and adjust the eye angle.
 The stamped heddle is the easiest to determine left and right, because the top and bottom loops are different. One end is straight.
The other end has a wavy top.  Line up the wavy tops in the same direction and the eyes should all line up correctly.  Decide if left or right threading is what you want and install with the wavy side up or down, depending on your choice.  Just make sure they are all the same.
This the end of the Leclerc repair heddle.  I love them and have several.
They slip over the heddle bars easily.
Just make sure the eye is facing in the proper direction for threading, just like a normal heddle.

If a whole shaft has the eyes backwards, it can be an easy fix in a lot of cases by just flipping the shaft frame over, just like flipping one heddle over to change eye direction.

Many weavers are not aware of these differences and can't figure out why threading the loom doesn't go as smoothly as they would like.  Take the time to fix the eye direction one time and have years of easy threading.  It will be worth it!

Making a Repair Heddle and Adding a Warp Thread

Life can change unexpectedly.  Four weeks ago today, I was diagnosed with ovarian cancer.  A week later I had major surgery to remove the masses.  After a week or two of healing and waiting for my chemo to start, I was thankful to have some weaving in the works that wasn't too heavy for me.  It is something I enjoy and can occupy my mind with something other than being sick.  I make dishtowels for all my girls every year for Christmas and I had started that project just before my diagnosis. I had part of it threaded, so was able to pick up where I left off.  I finished the threading, and then..... 

Oops!  I missed a warp thread right in the center of my warp and I discovered that fact after the whole warp was threaded through the heddles.
The loom I am using is my Leclerc Jano table loom.  It has wire heddles, so to do the repair, I need these handy diagonal cutters which are available in any hardware store.
 To get a better view, click on the picture. 

Clip the top and bottom loop on the heddle in the center.
Here is a better view without the cutter in the way.  This is just one of the extra heddles that were pushed off to the side.  Gently remove the cut heddle without unbending the wire too much.
Insert it into the proper spot on the heddle frame.  Tighten the wire loop a bit so it won't slip off.

Prepare a warp thread a bit longer than the other warps and thread it through the repair heddle from the back and incorporate it into the bundle of warp threads where it belongs.

Since everything was threaded, I tied my warp threads on to my front rod at this point.
When everything is tensioned correctly, I take the added warp thread in the back, and wind it around my fingers to take up most of the length.  Wrap some of the warp around the loops, fold it in half and insert an S hook into the to loops.

The warp thread dangles off the back of the loom.
The hook might be enough weight but if not, add fender washers until the right tension is achieved.  It should be the same as the adjacent threads.  If it is too tight, you will notice it when you start to weave because it will pull at the fell line.
 This is a handy little gadget used to spread the warp threads if any break while weaving or if you discover a threading error when you start weaving, or if like me, you miss a warp thread.
Insert it where the error is to hold the adjacent threads out of the way.  I made this today in about 30 minutes with a cedar shim, a utility knife and some sandpaper.  If you prefer to buy one, search for a warp spreader.  I have seen several that are made with nice hardwood.

If I happen to break a warp thread while doing these towels, I will do another post about that type of repair.
