First tie up

So I put my Julia loom together last week and I think my knees have recovered enough that its time to do the first tie up.

With 8 shafts and 8 treadles, I'm not sure how to do that.  Apparently there is no 8/8 "universal" tie up.  And I'll be weaving 4/6 to start with anyway.

So what do I do with the left over treadles and shafts???

Extemporating from my first weaving school experiences:

* when you beam the warp, *everything* (yes, everything: treadles, lamms, shafts...) should be *off* the loom: it should be beamed as a "bare frame" (with he exception of the beater, which holds the reed with the pre-sleyed warp)

* after beaming, take the beater off, hang the number of shafts you will need; thread the heddles

* that done, hang the beater again - sley the reed

* mount the number of lamms and treadles you need

* now start with the"upper tie-up": mount the horses (if using CB) and hang the shafts. If using CM: hang/mount the shafts. In both instances make sure the shafts are somehow held in position ("shaft holders" or, for CM, fudge it with using the CM pins in place)

* start the "lower tie-up": connect the lamms (one set for CB, for CM start with the upper lamms, go on to connecting the lower lamms, still with the pins in place)

* get out your tie-up plan. Tie accordingly: if CB, tie the lamms for sinking (all not-tied shafts will rise, due to the CB action); if CM tie all sinkers between upper lamms and treadles, all risers between lower lamms and treadles)

* tie the warp to the front apron rod; tension.

* free the shafts (take them out of the shafts holders and/or take out the pins). Test the sheds/treadles by stepping on them, one by one. Look for uneven sheds (shed floors - shuttles ride on the bottom of the shed, therefore it is of less importance if the top of the shed is even). Adjust shed floors accordingly.

* weave!

OK - so as soon as I had my own loom, I stopped stripping it to the bare frame between warps. However, I always take off shafts and lamms I don't use, as they tend to get in the way.

In my experience, the *only* important thing is that the shed [floors] are even, because that is where the shuttle rides.

- I also do not believe in "universal" tie-ups. It could be "just me", but I find it so much easier to have a "logical" treadling sequence than to have to memorize lots of combination treadlings. Besides, I weave on a CM, and any kind of universal tie-up is against the idea of a CM action...

With 4/6 there is a "sort of" universal tieup.

Assuming you will "walk the treadles" - place the tabby treadles (1&3, 2&4) either in the center or the outside of your six treadles.

Now, tie the remaining four to a 2/2 twill - 1&2, 2&3, 3&4, 4&1 - in an order that you can remember. (I do it left to right, switching feet in the middle).

This tieup is the one you can use for about 75% of Davison's "Handweavers Pattern Book" - good for tabby, twill, overshot, monk's belt, fancy twills, and many more.

By the time you need a new tieup, you'll be experienced enough that it isn't difficult at all.

My usual setup - tabby on the outside - is as follows

1. 1&3

2. 1&2

3. 2&3

4. 3&4

5. 4&1

6. 2&4

I do the same as Sara on my four shaft loom.  For 8 shafts there really isn't a 'skeleton' tie up as such because there are so many more options for combinations depending on weave structure.

cheers,

Be aware that the universal tieup presented above does not work for countermarche, if you want to use both feet.

(Or, if you wish to use it with a CM *and* use both feet, remember to tie for rising only - or for sinking only.)

Sorry about that! I completely missed this was a loom assembly tie up question, not a particular draft question. (I'll slink out of the room now...)

No reason to slink away!  I probably SHOULD pick a draft first, just in case it needs a non-"standard" tie-up.

But I'm having trouble settling on a first project ... and then I need to buy yarn ... all in all, very uncoordinated about the whole thing!
