Did you get an answer to your problem? I just set up my Orco 74 over the holiday weekend and I can take a picture of mine if it will help.
I would love to see a picture of the brake setup on a Orco 74, please! I have pulleys, hooks, a cord and a long spring. My loom is missing the handle for winding the warp and setting the rear tension? The rear drum fits tightly in the rear housing, no room for a sprocket like the front. Help, I’m itching to get started. We have a grandchild on the way! Thank you!
We have not satisfactorily resolved the issue. Your photos of what a correctly rigged brake tension aparatus looks like would surely help
Thank you for offerring.
