Megado harnesses are sticking

The Megado harnesses are very compact, close together. When changing picks on the Megado, harnesses fall back to the rest position through gravity. Since many weave structures use harnesses 1-2 more than other harnesses, we have weighted these harnesses. If during weaving, your harnesses are sticking and not returning fully to the rest position, 99% of the time, the problem is friction between harnesses.

Too much friction/resistance will prevent harnesses from returning to rest. Most often, this is due to having extra heddles on the ends of your harnesses. If you have extra heddles, they need to be spread out so they do not bind on each other. Staggering heddles from left side to right side can help with this issue.  (ie harness 1, extra heddles on the right side of harness 1.  Harness 2, extra heddles on left side of harness, etc)

Another possibility

A harness can also be slightly bent (particularly on a wider loom).  A quick fix is to remove that harnesses texsolv cord from the groove of the harness and place it on the side that's catching.  For example.   harness 5 is catching on harness 4 - the wood of harness 5 actually rests on the right side of harness 4 when you release the treadle.   Take the texsolv cord of harness 5 out of the harness end on the right side and let it rest between harness 4 & 5.   This small amount of lateral tension will allow harness 5 to miss harness 4 and eliminate the catching.

A Third possibility, although more common on older looms.

Since the dobby hooks are very close together, build up of weaving dust can actually begin to create resistance between hooks.   Also, is humidity or moisture an issue?   We had a customer in Florida where the climate was humid, combined with weaving dust and the dobby hooks started to bind on each other.     The solution was to use fine sand paper between the offending dobby hooks (I would actually sand all 32 hooks on both sides).   Second solution is to spray a small amount of dry teflon lubricant spray between the dobby hooks.

Fourth possibility
Dobby hooks could have worked themselves too low, a slight stretching of the texsolv.   See page 38 of Megado Instructions

Here is an excert...

Another reason for the problem that a screw head does not come high enough to block its
non-selected shaft could be the level adjustment of the shaft in its cords, i.e., the shaft comes
back to its lowest position, but at this position the screw head does not slide over the
blocking plate snapping into the locking position. To check this you need to take the dobby
mechanism or interface off the loom first. When the shafts are in their lowest position, there
must be a 2-3 mm (1/16"- 3/32") clearance between the screw heads and the blocking plate.
If it is necessary to adjust this distance with a shaft, follow this procedure:

To prevent working on the wrong shaft, mark the shaft that needs adjustment with a piece of
colored yarn on both ends. Loosen the small bolts of the clamps that hold the shafts on both
sides to the cords just enough so that the clamps can be moved on the shaft ends. (Please
note that the heads of these bolts require a Phillips screwdriver, not supplied with the loom.)
When the bolts are loose, you can adjust the shaft in relationship to the cords, and by doing
so, to the dobby hook. Tighten the bolts again while the shaft is in its lowest position and the
head of the blocking screw is 2-3 mm (1/16"-3/32") above the blocking plate.
