About That Knee Beam .....

I have been weaving away on a one yard sample warp, trying out various yarns and ideas with multiple tabby weave. Things were going pretty well until I advanced the warp. I was surprised that as I treadled, my knees were hitting the apron rod. That had never happened before. Finally, after treadling bow legged for a bit, I stopped to take a closer look.....


That's when I realized that the apron cords weren't going over and behind the knee beam. Somehow I had missed it altogether when I pulled the apron rod up to lash the warp to it.

If I had puzzled about usefulness of that knee beam before, I certainly understand its functionality now. And I won't forget to make sure my warps travel the correct path anymore, either!

Wow, this is really amazing! I had to run and take a look at my looms. I have never heard of a knee beam. I was relieved to see that neither of my looms has one. I thought I had overlooked them all these years. I can see where it would be helpful though.

Been there, done that :-)

(Release the warp tension, lift off the knee beam and put it back from underneath the apron cords).

I've never heard of one either (I don't have one) but I can see how it is used. I'm musing on the name now.....

So that's why they call it a knee beam...! Thanks for letting us in on the secret.

Doh!

I agree, it was a bug doh *lol* Kind of like the first time I warped this loom and somehow had the cloth winding around the cloth beam backwards. ;)

Textil, thanks for the tip! Brilliant!

You are not the first to do this. Only a couple of looms at the school have knee beams, but without fail, when a student put a warp on one of these looms for the first (or sometimes second or third time) they forget to warp around the knee beam.

I'm not laughing at you - I'm laughing with you. I made the mistake on one of my first projects of not lowering the back beam and running the warp *over* it - then I couldn't figure out why I couldn't get a shed. I'm glad I don't have a knee beam so I can't make a mistake with it &^)

I've been guilty of this too, Leigh! You are in good company. Just remember, only God is perfect. :)
My, look at all that weaving space on that loom! Hmm...bigger projects in the works?

Looks like there's a bunch of us that make pretty much the same mistake. I don't have a knee beam but made the same sort of mistake with the back beam and hate to admite but more than once.

The GlimÄkra makers seemed to anticipate this problem by designing a beam which can be lifted in and out. Your problem (and mine too on my last project!) can be solved easily. It makes one want to give a little jump for joy.

I've done the back beam one not the knee beam one yet.......

Dorothy said...

I've done this too! In fact, when I started weaving I actually wove a couple of warps before I worked out what the knee beam was for!!

Pretty colors in the piece on your loom. What do you do with the loose weft ends? What are the yarns? Thanks for a great blog!

Leigh said...

Thank you Michele! My next post will be about that very piece!
