    The pretty one on the left is the 1930 model...
    I believe the 1930 on the left is a model 127 and the 1929 is a model 66.

    You can check the serial numbers here to confirm the model family and date the # was authorized.

    Thanks! I'll visit the link you provided and confirm that.

    Those things are a joy to use. For light work and quick tasks, they excel!

    Those two are some beauties Mac!
    I spent the day building a new sewing table for Stella, cleaning my sewing room, adding a new foot peddle to Judith and just generally getting ready for the Texas Hang...

    You are right about the style, Rat... Stella looks like it was designed by the same folks that created some of the WWII aircraft!

We've all had the experience of coiling rope where just one more twist, even over a span of several feet, causes a rope to lay wrong or subject it to risk of tangling.

    But, thread is put up on tapered spools so there is no additional twist if it comes up off the top, correct? And if so, there is an unexpected twist if the spool rotates. Please correct this if wrong.
    Not sure how I missed this discourse earlier, but...

    Spools are wound one of two ways:
    Straight wound and Cross wound, a spool is a spool; we say spool to mean the 'regular' small spools for home use but a cone is also on a spool. It is how the thread lies on the spool that causes us to call it a cone.

    The small spools are straight wound.

    Sometimes the larger spools are cross wound as well. The Gutermans thread we all use is cross wound, but it isn't shaped like a cone. Again, just look at how the thread lies on the spool.

    Cones, on the other hand, are almost always cross wound.

    In either case it doesn't matter which end is up or, on a straight wound spool, which side the thread spools from.

    A straight wound spool needs to be on a vertical pin with the thread coming off the side of the spool and the spool rotating.
    A cross wound spool/cone needs to have the the thread coming off over the top but the spool does not spin.

    It is easy to see the difference in a straight wound spool and cross wound spool. The straight wound spool has the thread laid up nice and parallel; cross wound is spooled on a bias. The difference is easily seen on the cone; the bias wind forms a triangle pattern when the thread lies on the spool.

    If it is wound straight it comes off straight... No amount of distance will 'untwist' the thread if it is spooled off incorrectly. Eventually the thread will twist so badly it will cause breakage, jamming etc. This is caused by the twisting thread increasing in diameter and eventually fraying or wreaking havoc with the tension.

    Below are: Cone cross wound, Gutermans spool cross wound and Spool straight wound; the bias is clearly visible on the left and center spools.

    Rat, for the old fashioned curs and sailors among us...

    straight wound is loaded by turning the spool, the way a winch works, so you have to turn the spool to unwind.

    cross wound is the way kids used to use a kite string... or the way a net needle is loaded.

    I believe this is correct. Stella would know!

    Yes, that's the basic idea; even though in the manufacturing of spools of thread the spindle is turning. Cross winding machines use a motorized arm to place the thread at a higher rate than the rotation of the spool. Straight wound use a free arm that allows the layup to form naturally. Just like you said, a winch and a kite string spool.

    Cross wound spool


    Good info on spool vs. cone.

    So, I just happened to check craigslist after reading this thread and found a 500A for sale locally (just a few miles from where I live)...

    http://seattle.craigslist.org/sno/art/3378019851.html

    If anyone is interested, I'll go check it out in person... There is no need for Stella envy...
