The improvised picker returns work fairly well, but now I have another problem: the shifitng of the boxes.

Sometimes (maybe a third of the times?) when I shift the boxes, the one coming up stops short of at the correct height. Another try will get it all up. This happens at both sides, and from what I can see the elastics are not in the way.

Is there some maintenance I should have done? I looked through the manual but couldn't find anything on that. It has been more than 6 months since I last used the double boxes. I have tried to lubricate everything I could think of, but the problem doesn't go away.

Any tips?

On my AVL double box there are set screws that can be adjusted to fine tune the drop and lift height.  Maybe they need re-adjusting?

Is it the shuttle sticking out too far preventing the box from moving all the way?  (That's what happens on mine, but I have a different system so it may be unique to my loom.)

cheers,

It can't be the screws, as their function basically is to prevent the box from rising too high - mine now stick at the middle height.

I don't think it can be the shuttle sticking, as the shuttle in q is trapped on the lower level. When I want it up for weaving, it sticks. I'm thinking that the fact I was able to lower the box with shuttle inside should nudge the shuttle "enough" not to create a problem? The side that lowers always goes the whole way - it is just the rising side that sticks.

(I suppose it can be a pilot error - as I said, for the last 6 mo or so I have been using the single box... a longer session tomorrow will tell)

The problem is identified. It is partially a result of the improvised picker return, partially a pilot error.

The way I mounted the improvised "returns" (buttonhole elastic) means that the picker does not quite return to the starting point (a matter of about 0,5 cm, more or less 1/5") and the pilot's hard throwing of the shuttle - the shuttle sometimes can stick out "under" the picker, preventing the free movement of the box:

As you can guess, the workaround is "put something on the picker to make the shuttle move over a bit" - in this case a piece of paper, tied to the picker.

It works, but after some 1500 picks, it looks like this:

which means I have to find something more durable than paper...

What I'm weaving? A double-layer scarf:

However: I still can't understand: as I first send the shuttle to the left, then lower the left side box - why doesn that not "nudge" the shuttle far enought to let the box come up next time?
