Greetings! My hubby and I have designed some Shaft Risers that work great on the four shaft Harrisville looms. We have not been able to come up with a design for the eight harness loom at this point.
The Shaft Riser for the Harrisville loom not only separates the shafts so that you can see which one you’re pulling a heddle from, but it also stabilizes them somewhat so that in my opinion anyhow, they make threading much easier.
Here’s a link to a Youtube video of me using mine. They will come with enough texolve cord and pegs to use on looms with a castle. $35 includes shipping in the US. Please pm me to order.
