Loom upgrade continued (fixing the floating harness problem)

Since the “loom upgrade” or adding the 4 extra harnesses to my LeClerc Minerva I’ve run into what I’ve seen described as a common problem with jack looms and 6+ harnesses – the floating harnesses. The LeClerc site suggested adding weights. Wandering around my local hardware store I found something that seems to work. I’m not sure what they are or are actually for but now are loom harness weights.

So far this seems to be solving the problem. I don’t know if anyone else has had any experience with this? Solved in any other manner?
