Threading with the AVL Cross Maker

I set out to thread a warp today on my 24S Glimakra but ran into problems. I had the threading cross on lease sticks suspended as usual  right behind the heddles. Note the cunning use of the snitch knot to get the lease sticks at the right height!

Normally reaching through the gap between the heddles (24 shafts worth of them) to pick up the next thread from the cross is fine but because I have slightly wrenched my shoulder playing tennis I found this tricky today.

My solution to the problem has been to move the threading cross to in front of the heddles. I have used the cross maker from my AVL warping wheel to act as a little set of lease sticks and the photograph shows the rather industrial way that I am holding it in place. The selected threads are easily slid of the ends of the sticks. I thread in blocks of four, selecting and grouping the correct heddles and then taking the threads off the cross. I still have to reach through to bring the threads into the correct position for threading but it this is much easier on the shoulder (and the eyes) than trying to get hold of threads that are 2 feet away.

I have a rubber band (not shown) that I put into place on the cross maker to hold the threads firmly in place. I put this on every time I get up from my sitting position which is the danger time for knocking things out of kilter. I take it off again when I am settled back down again and ready to resume threading.

The next photo shows the total set up. The ubiquitous milk crate ( I have seen a students bedsit completely furnished with these) is just the right height for a seat. The loom controller foot pedal is sitting on the knee beam and always remember to take your watch off before starting to thread.

I have a special threading draft that lifts each shaft in a block of four in turn. This is when I select the heddle. After I have threaded them I use the draft to lift all four shafts together so I can check that all is correct.
