Start at the top of the loom and locate the centre. This Glimakra loom is 60" wide, so the centre is at 30". Now locate the centre point from both edges to the centre. This is where the upper pulleys for the shafts should be placed. The pulley is 1" wide, so I place it at 14.5" from the edge of the loom.
	It is important that the tie-up to the shafts is perpendicular and centered and that each tie-up yarn is of equal length. I use texsolv cord, as it is easy to check that each cord is the same length, by counting the number of loops in the cord. The distance between the notches on the horses is 6". To check that the tie-ups to the shafts are also perpendicular, they should also be 6" apart, and the texsolv cords should be at right angles to the upper shafts. The distance from the edge of the shaft to the outer tie-up cord is 13".
	With your loom threaded, check on the side of the loom to see that the warp is running through at the centre of the heddles. If necessary, adjust the height of the cords that run from the upper pulleys to the horses. On this loom, this distance is 12". Note: I have placed a rod through the small holes at the ends of the shafts, to help hold them in place while setting up the loom.
