POSITIONS OF SHAFTS, UPPER LAMMS, LOWER LAMMS,
AND TREADLES

If a treadle hits the lamms, lower the treadle that is hitting
by loosening all the cords that are tied to that treadle. Begin
with the tie-ups on the back shafts, since these are most
often the culprits.
The Y-cord (from the upper jacks to the lower lamm)
passes in back of the shaft and the upper lamm. The
cord from the treadle to the upper lamm passes in
front of the lower lamm.
VIEW FROM THE SIDE
To open the same shed height at the fell, the
shafts must form a bigger shed the farther away
they are from the fell.
