David harness adjustments

The David loom assembly requires that you adjust and set your harness heights yourself. Louët provides fixed height positions for shafts 1 and 8, and the remaining shafts must slope evenly between them.

All Texsolv cords used to attach your shaft bars are carefully measured and installed at the factory. Always attach the shaft bars to the last usable loop of each Texsolv cord. This is important—using any other loop will make it much more difficult to achieve correct shaft heights. Louët supplies detailed information on Texsolv cords.

If you are experiencing a split shed—where some warp threads sit slightly higher or lower than the rest—you will need to adjust your harness heights, most likely between shafts 2–7.

Shaft heights are adjusted at the lam, where the Texsolv cord connects to an eye bolt secured with two nuts. Only the lower nut is functionally required; the upper nut is used only for shipping. Louët sets an approximate starting position using a jig so that most shafts begin close to the correct height.

Bottom shaft bars must always be attached to the last usable loop. Do not attempt to adjust shaft height by moving the shaft bar to the second or third usable loop.

How to adjust harness height – Loosen the top nut so it is out of the way. Raise or lower the bottom nut to adjust the height.

• Lowering the nut lowers the shaft bar

• Raising the nut raises the shaft bar

Adjust each shaft so it follows the correct, even slope from back to front.

This process can be tedious but getting it right the first time will save significant frustration later. Attention to detail is essential at this stage.

Here is an excellent article and video that shows, in detail, how to adjust your harnesses.
