We recommend that you take steps to examine and tune-up your loom before every project. Here are a few things to check for: 1. Be sure your harnesses are hanging at about the same height. If not, you can move the s-hooks connected to the harness cables up or down the corresponding adjustment chain. You can also adjust the copper collar on the harness cables, then move the two cable lengths in opposing directions until the harness is level. 2. Be sure that all harness and lamm cables are sitting on their corresponding pulleys (refer to your loom manual to see how they should look). If not, follow each cable back to its harness or lamm and move it back to the correct pulley (be sure not to twist cables in the process). 3. Check that all nuts and screws are fully tightened. There are a few fasteners that should be left loose enough to allow the piece to move freely (such as the brake pedal, pawl, brake bar, etc.). 4. If any moving wooden parts, such as pulleys, start to stick or squeak over time, you can use spinning wheel oil as lubrication. A needle nose applicator is helpful to fit in tight spaces.
