I decided to change from the original cotton heddles to Texsolv heddles on my 1970s era Cranbrook. It seems the original cotton heddles are longer than the Texsolv white tie heddles (11") and shorter than the blue tie heddles 11 1/2". So, when I went to put the new 11" heddles on my loom, I could barely move the heddles on the shafts. I can shorten the side metal pieces between the shafts or I can make new ones to make them longer for the 11 1/2" heddles. I've been on the phone to Schact, and we finally decided it would be easier to shorten one of the metal pieces 1/4". Before I take the Dremel tool to my loom, any feedback? Is there any advantage to having a shorter or longer heddle?
