Notes: 

This loom was given to me, already threaded from the spools, in original Lily 20/2 cotton. I decided to try out the two Atwater patterns in the instruction manual to see how the loom would weave. It weaves GREAT. Once I started weaving, I realized the original owner used the wrong colored spool in the middle. So I replaced that spool with the right color, only to find that spool had more yarn on it, hence it fed into the weaving at a different rate than the rest. So I had to rig up a bit of weight on the back so that it would feed consistently with the rest of the spools, under similar tension. Each bottle weighed 4 oz, so that was just over a pound of weight on that one spool.

If you want access to the drafts, they can be found under the files folder over at [email protected] 

I felt a little badly these designs didn't come out squared. On such a small loom, a "large" design like this disappears before you get a chance to visually make sense of it. The surprise for me was comparing my sample to the picture in the 1950 manual—their sample pattern was also elongated! (I didn't feel so badly after that.)

That's a great pattern.  And

That's a great pattern.  And of course, the Structo just jumped right out at me when I checked the recently finished projects (big surprise that!)

240-4

I just got a 240-4! Would like to find spools and the spool hexagonal spool holder. It is somewhat threaded on the roller.

For spools

You can certainly watch Ebay and other sites to see if they come up for sale, but frankly I have replaced all my spools with plain beams.

Unless you know *precisely* what you are doing and can wind every spool under exactly the same high tension (the yarn in the spools should be rock hard), and wound with a spacer to keep the threads in exact alignment to keep them from biting into the previous warp, you will probably have better luck using your 240-4 like a regular loom.

I tried reloading the spools using a short warp of the same epi as the original, under high tension, and it wasn't very successful. I had to make thin cardboard strips to put between the warp layers on the spool, as the warp wound on inconsistently. Without some kind of guide, the warp would pile up on one side or the other of the interior of the spool.

Ironically, I found an original Structo Spool Warping tool at a studio sale a few weeks ago. I need to find my spools and give it another try. The tool has a comb-like device with very fine teeth (30 epi), that guides the warps into a consistent path within the spool.

If you don't want to weave at 30 epi, again, I would recommend going to the plain beam, which can handle a variety of warp grists.

Just some thoughts:Looks

Just some thoughts: Looks like a sort of sectional. With a tension box with comb to fill the sections, maybe this is an option? Like a sectional or flanged warp beam, the warp has to be to width and even, going on like a flat sheet. Since the dividers are large, you have to compensate in the sections with enough density to thread in the reed enough ends for your width. So 48 epi in the sections, might translate to 32 epi in the reed. I deal with this on my sectional, as my sections are full 1" wide, not 7/8" (taking into account 1/8"  bent rod for the dividers) so I actally gain 1/8" in width from section to section across the width. Might be 35 sections to get ~40" of width for instance. :)

"Portable" sectional, yes.

I see what you are saying - yes, each spool has 60 warps wound on them. (60 x 4 spools = 240) When I tried this, my results were dismal. I am willing to try again with the Structo device I picked up a few weeks ago, as the very fine comb is the key. And yes, I would have to double the warps in the 30 dent comb to feed into the spool at 60.

Having seen contemporary industrial warp winders, I can see why individuals trying to recreate this process have difficulty. I think Structo had these spools wound on industrial machines, and the home winder products probably won't produce nearly as good of results. The warp wound on each spool from the factory is rock hard. Even with a tension box and an appropriate-sized comb, I am not sure that I can manually apply the amount of tension needed to achieve that same firmness.

For Structo (and other loom companies that had similar systems) the idea was to make additional money selling pre-wound spools or warp beams. Considering how much many weavers hate warping, I can see where it would be enticing!

FYI, these looms are called "240-4" because when they came from the factory, they had 4 shafts, 60 heddles per shaft, and a 15 dent reed.

The spools were loaded with 20/2 Lily cotton, planned for a sett of 30 epi (2 per dent) at 8" wide, so the owner had a total of 240 warp threads - hence the name. It was expected you would weave at full width, with the provided warp.

P.S. The backstory

This was the project where I re-loaded a set of Structo spools. The warp was only 4 yards long. Most might be happy with these results, but being used to perfectly tensioned and taut warps, I was not a totally happy camper when weaving.

I got the weaving completed (which was a slow process anyway due to the technique). When the project was finished, that's when I made the decision to shelve the spools on my Structos.

Interesting project in the

Interesting project in the link. I've always thought of doing something like this but a narrow project  like your scarf or runner, and do some Barney and Fred cartoons or something. Remember the vitamins commercial for Flintstones vitamins? 10 million strong and growing! Even my grandfather liked that cartoon, it was a lot like Jackie Gleason, but in cartoons. Back to weaving. :)

I DO remember

And... I even have the plastic Flintstone car that came in a box of Fruity Pebbles, vintage 1970s.
