The Kromski heddle and heddle blocks are designed to hold the loom solid in the up position IF the tension on the warp is fairly tight. Not break the beam tight but it is best described as drum tight. That is a term I have used when teaching miniature punchneedle embroidery which also needs to have the cloth in the hoop "drum tight". On the hoop it is easy to explain - tap on the top of the cloth in the hoop and it sounds like a little drum. With the loom, the warp is not going to make any sound if you tap on it, but if you push gently down on it about an inch down there should be resistance. Here is a photo with my fingers pushing down on the warp when the heddle is in the up position -
You see just three fingers lightly pushing down. On just the warp threads it pushes only slightly further (a photo did not show this well). Getting the tension here is not hard. Wind the warp to put some tension on it. Put the heddle heddle up. If it does not stay up by itself or it falls, increase the tension on the warp to the point that the heddle is solid on the top of the blocks. Like this -
See how the warp holds the heddle in place. And see that there are on need for rubber bands wrapped around the top of the heddle block and there is certainly no need for cutting into the notch on the top of the heddle block! Wow! Somethings that I have heard people do rather than get the heddle to stand as it was intended to.
Once it is staying up there, if you feel there is too much tension, then open a pawl (front or back) and move the ratchet one or two notches less. Put the pawl back on the ratchet to lock it and put the heddle back up - if it stays fine. If not, the tension has to go back to where it was - one notch at a time if you lowered it more than one notch.
One thing to know about putting the heddle in both the top and bottom positions is that you pivot the heddle into place. See how the bottom of the heddle frame sits in the notch in the photo above. Put it there first on an angle with the top of the heddle toward you and push the top of the frame up to put the loom straight on the block. It will move against the back of the notch and stay there.
For putting the heddle in the bottom position it is the same thing - with this same tension, put the TOP corner of the heddle frame on the top notch - both sides at the same time - always - and have the bottom of the heddle frame coming toward you. Have your thumbs push the top of the frame toward the back of the loom so that the bottom of the heddle swings into place to the bottom of the heddle block - and it will make a sound "SNAP" - you might even say "Pop" as in Pop Goes the Heddle. 😄 It makes a very definite connection - and stays there! I love the sound the heddle makes when it snaps into place on the bottom position.
Here is the heddle in the bottom position -
So - it really does work. Don't crank up your tension to the point that it will do damage - but the tension has to be correct for the Kromski heddle to stay solidly in place - up or down! And each time you advance the warp you are releasing the tension to wind the cloth on the front beam and when done you need to return the tension to where it was.
When you finish weaving for the day - or will be away from the loom for several hours, take the tension off the warp - just enough for the warp and cloth to go slightly slack - not too much! This will reduce any stretch on the warp and also any stress on the loom while you are not weaving.
