My floor loom is a LeClerc ‘Minerva’, 23” weaving width, folding jack loom. It’s a ‘4–now-4–later’ model that allows you to add an additional 4 harnesses.
Because I’m interested in doubleweave I had always planned to add the extra set. Last summer I finally ordered the upgrade kit. (I guess you’d call this an upgrade kit, weaving being the ansestor of computers and all that…)
Before and after pics. 4 to 8 harnesses, 6 to 10 treddles.
Early on I found that with the extra harnesses (this is specific to jack looms as I understand the issue) – 6 or more, there is sometimes a problem with floating harnesses. Fortunately the LeClerc site describes the problem and makes helpful suggestions. Rummaging around at the local hardware store turned up something that I could use to add weight to the harnesses. So far this seems to be solving the problem.
Here’s my first attempt with an 8–harness twill. Pattern: Reversing Point Twill by Kris Bruland,

for 8 Shafts, 8 Treadles. (Someone correct me if I’m wrong but aren’t shafts and harnesses interchangeable terms?)
