It's a Shed, Not a Barn

One of the reasons I like my small counter balanced loom is that it makes great sheds.

What is great about this shed, you may be asking?  Isn't it a problem that the upper 'ceiling' of the shed is split?

Actually, no, it isn't a problem.  In fact I didn't even notice that it wasn't even until after I'd woven a towel and was halfway through the next.  :)

The thing with sheds is that they are just that - a shed, not a barn.  The threads only have to open sufficiently to  let the shuttle pass freely from one selvedge to the other.

IMHO, a shed to be considered good needs to have the following:

The floor of the shed must be even.

The floor of the shed should not change elevations every time you open it.

If the loom has a shuttle race the shed floor should be on the shuttle race, not floating above it in a different place with every opening.

Counter balanced and countre-marche looms form their shed floor by pulling down on the ends that form the shed floor.  Jack or rising shed looms create the shed by lifting the ceiling ends to form the shed.  Some rising shed looms do this better than others.  For example, my AVL forms a fairly small shed but with a good floor because of how the shafts are situated - they are not all on the same level but slowly descend in elevation and are held in place with springs which keeps the shed floor tight against the shuttle race as the rest of the shafts lift to make the space between the ends.

So, am I going to change the tie up on my Leclerc Fanny to make the ceiling of the shed more even?  Probably not.  I'd rather be weaving.  :)
