It is easy to understand why they put large suction discs on the bottom of the Speedylock 1600. My problem with this serger is the amount of noise and vibration. While that is definitely important, it is not the only important thing about using a sewing machine or serger. Lots of sergers don’t have this feature and it is certainly appreciated when working on cuffs, collars and navigating small spaces. The workspace is not the largest I have ever seen on a serger, but it is large enough so that working on the Speedylock 1600 is not uncomfortable or cramped. Differential feed and stitch length/width adjustment dial Somehow, even though I’m lefthanded, I think this control would be more efficient if it were placed on the right side instead. The differential feed and stitch length/width adjustment dial on the side is easy to understand and even easier to manipulate. I have very little doubt that a child as young as ten years of age would be able to master this task with just a little bit of adult supervision.

Unlike many other sergers made around the same time, the easy to follow thread guide inside the looper coupled with the lay in tension system make threading simple enough for someone who has never before seen or worked on a serger to be completely at ease. Threading the White Speedylock Model 1600 and getting it ready to go to work was easy.

Working on the White Speedylock Model 1600 The accessories, however, are all stowed in a convenient case that holds everything you will need very neatly. I was disappointed, however, to discover that there is no on board storage for frequently used accessories like tweezers, a needle threader or extra needles… the things you need to have at your fingertips when working on any serger. When you open the looper door, you will see an uncomplicated, easy to follow threading path that is in my opinion, designed to help make the beginner very comfortable with the whole process of working with a serger. The markings on the dial clearly shows how easy it is to select the settings for stitch narrowing and widening or to handle sewing curves of any size or angle and to make fancy edges for tops, dresses and skirts.

There is a huge dial on the left side of the machine that controls the differential feed. The White Speedylock Model 1600 looks pretty much like all the other sergers manufactured at the time with one glaring exception.
