Greetings Harrisville loom lovers! I’ve gotten dear hubby to design a shaft riser that will work on the 4 shaft Harrisville looms. We tried to create an 8 shaft version but was not able to figure out a good way. These shaft risers work great on the 4 shaft loom however and I think are a big help in threading in that not only do the shafts rise in a step up manner but the riser also separates the shafts approximately an inch apart so that also makes seeing the shaft you want to pull a heddle from easier too. Here’s a link to a quick video I made of how to install and use them. Please contact me via email or private message on Facebook however email is preferred.
