rods for warping #weaving
|
Jane Eisenstein
I like to use rods for lashing the warp to the warp beam and weaving headings to lash to the cloth beam. I'm currently using a couple of flat narrow wood sticks in the heading and they are bowing under tension. I've also used wood dowels in the past.
I'd like to get flat metal rods, but not seeing rods with the right dimensions at my local hardware store that are not aluminum. I'm concerned aluminum would bend under tension.
Do you have suggestions for narrow, unbending rods?

Thick walled steel tubing will give a higher ‘strength to weight’ ratio. Investigate what is available at a nearby steel stock-holder.

Jane,
I use 1/4" or 3/8" cold rolled steel available from most welding shops. The 'cold rolled' form rusts less, and to further prevent that, I wipe it down thoroughly and coat it with paste wax. The rod will deflect a bit with narrower warps but will return to
its original form when the tension is removed.
That rod is then lashed to the apron rod or inserted directly onto a string apron depending on the loom.

I've used a metal tube with a wooden dowel inside of it and it works well. Janette

I'm not a big fan of metal rods. I use sticks made from hard wood. One thing that would prevent the bending is only lash the width of the warp, not the entire length of the warp. That advice came from Jane Patrick (Schacht-Spindle owner)

Metal rods are far stiffer than wood and less likely to break catastrophically, using tube increases the strength/weight ratio. Certainly it makes sense to ensure the width of the fabric is lashed and not depend just on the ends.

May I ask why you use the combo instead of one or the other? Thanks! kathyo On Nov 16, 2020....

I ordered a stainless steel solid rod from https://allmetalsinc.com/ . The rod itself was cheap but the shipping wasn't. But it was exactly what I wanted.

bamboo is supposed to have a higher tensile strength than steel. Has anyone used bamboo?

It is true that the tensile strength is higher (weight for weight) , but the feature which matters is the bending modulus (ie stiffness) where steel wins.
Bamboo is also weak across the nodes, the joining two growth points where it breaks in bending.

Hi Everyone
You are going to need 2 rods and cord if you want to stop the bowing of the rod
rod for tie on -------------------
cord lacing /\/\/\/\/\/\/\/] This is the best I can do for example.
Rod in hem of apron -------------------

Kathyo, my DH had tge opinion that metal tube would be less likely to bend with dowel. My 3/4” dowels bowed only when I tightened it too much. But together DH thght they would not bow or bend.

I use hollow aluminium rods which are a centimetre wide and a metre long. They never bend. I lash my rod at either end of the warp (and once in the middle) - to the warp beam.
I had solid metal rods, but they were very heavy and so, for me, a nuisance. They are available in any hardware shop here in France. Ann

Hi Everyone
I have a Cranbrook loom two of them 1 48 and the other 63 wide
Now who makes the Cranbrook looms? Schacht-Spindle Jane Patrick's husband, Now the example I sent to the list about how to stop a rod from bowing is how the rods are set up on my Cranbrook loom There is a misunderstanding here some place. :>)

My second-hand loom came with (I assume steel) rebar for the rods.
I have seen the same product at the big box hardware stores.

Joe, I laced the width of the 12" warp plus an inch on either side to the cloth beam rod and am seeing bending. Sounds like I should have not laced beyond the warp's width. Right?

I also have a very strong metal rod on one of my looms. I find the heaviness of the rod makes it a bit more difficult when lashing on. The aluminum tube with a dowel inside seems to be just the right weight and it does not bend. I also only lash on the length of my weaving, but I want high tension for my work so it's important that rods do not bend. I like the other idea suggested of using two rods. I have not done that yet, but it makes sense. Janette

Using rebar has been discussed before. Rebar (steel rods used for
reinforcing concrete) is designed to be easily bent. It is bent to fit the form to be reinforced. So not the best tie on rod. Mild steel works much better. Sandra
