Please note the construction of the foot assembly for the 107wsv. It is open in the center and each toe moves independently of each other up and down. Each toe is also hinged independently and can pivot on its hinge point.

The 107w class of machine is a Wheeler and Wilson style hook machine. New Wheeler and Wilson hook machines are not available for Embroidery, due to lack of demand for machines that would incorporate this expensive style of hook. New standard zig-zag sewing machines with Wheeler and Wilson hook are available for regular zig-zag sewing. They are typically in the $3000. range on up. The Wheeler and Wilson style hook is the smoothest hook design. It is fully capable of working with size 5 needles and correspondingly very fine thread. On the other hand, regular 107w's (107w1, 107w3, etc.) with Wheeler and Wilson style hooks are widely used for binding carpets with size 24 needles! This exceeds the performance capability of standard hook machines.

Some dealers are familiar with "Singer Irish" machines. These are called so due to their association with the manufacture of Irish and other dance dresses. The best of these is the 107w102. This machine is the same as the 107wsv, but has no feed dog! The operator moves the work by hand. This is a very skillful operation. When not done correctly, the satin stitch will not be consistent. Still this is the widely used professional model. More recent versions (without feed dog) are the 20u62 and 20u142. The 20u63 and 20u143 with feed dog are considered to be much more user friendly, ensuring an exact satin stitch length. To use the machines without feed dog, you must be highly practised!

The 107wsv is not a common machine. In fact, the 107wsv is not known by many dealers, even those involved in Irish dress machines. If you ask for one from a dealer who is familiar with Singer Irish machines, he will almost certainly tell you he can provide one, and then provide you with a 107w102 instead, believing that is what you had meant to say, and that there is no such thing as a 107w102 with feed dog. In fact, in the excellent book "Advanced Embroidery Techniques" published by B. T. Batsford Ltd., London, the author Beryl Johnson (who details the use of Singer Irish machines), laments the fact that the 107w102 was not made with feed dog, when in fact one was! I believe that very few 107wsv's were made. I was fortunate to hear from an old timer in the Irish Dress industry about these machines long ago. He said they were unobtainable in general, so I have scoured all sources over the years, and now have a few.

The 107w class of machine was made in the USA at a time in which quality was important. It is of a heavier duty class than the 20u machines and the knock-offs of that class. It is actually designed for continuous duty, that is, 24 hour a day service. The 20u143 and similar machines will be fine though for most applications, and will give long life when used in standard 8-hour a day shifts or less. The main problem anyone has with the feed capable machines (20u53, 20u63, 20u143, B-652, etc) is that the foot obscures the work, and this is where the 107wsv has a great advantage. The other alternative is to use a "Singer Irish" type machine without feed dog, which of course, allows full view of the work.

All of the embroidery machines discussed in this document have a knee control which allows the operator to vary the width of the zig-zag while sewing, or the control can be set for a given width (normal setting).
