The Master Key

With the variety of accessories and attachments that one can use on these machines I decided that I needed to test out every one of them if I can. However, I wasn't interested in taking parts out of one of the "books" or "Towers of Power" so I designed a master set.

With the large number of parts that I had acquired, I was thankfully able to give each machine its own unique set according to its manual and still have plenty left over. With this I created my own master set, a master key to unlocking all the possible potentials of the sewing machines.

Lets note that first I purchased an adapter off of ebay between the Super High Shank to Low shank, so that if I had any attachments that were some how special or unique to Low Shank I could use them (in this case one of the monogrammers and a buttonholer)

The standard attachments that all the machines can work with are the same across all the lines, and are pretty typical to any sewer.
  • Zipper
  • Cording
  • Overcasting
  • Open toe/Applique
  • Straight Stitch
  • Zig Zag Stitch
  • Satin Stitch
  • Plastic Zig Zag
  • Plastic Satin
  • Binder
  • Edge stitch
  • Narrow Hemmer
  • 1/4 inch Hemmer
  • 3/8 inch Hemmer
  • 5/8 inch Hemmer
  • 7/8 inch Hemmer
  • Gathering
I was additionally lucky enough to find SHS feet in these varieties
  • Ruffler
  • Walking foot without teeth on the upper dogs
  • Walking foot with teeth on the upper dogs
  • Low shank ruffle/gathering with slit for a straight material
  • Quilting foot
  • Wide base monogramming foot
  • Modern Kenmore Monogramming foot
I will check each of these feet for alignment as I am aware that the 1802 and 1601 models have different alignment of the needle bar to the throat plate, but may not end up sewing much with them. I plan on using a Satin stitch foot for the vast majority of my testing. In this case that will be the B foot according to most documentation related to the devices.

The Master Key set also includes one of each of the monogrammers that I mentioned in the monogramming post. With the adapters for the low shank to the Super High Shank, as all the machines in my set are SHS. I'll see if my theory works on these larger mechanical bits. As I already know it works on the regular feet.


I will test a variety of buttonholers on the machines as well, the buttonholers however have little to no variation besides material and how you select the button hole and the shape of the cam. The one difference however being a low shank more modern buttonholer that takes its queues from the original buttonholing feet seen in the 1940's nd 1950's. Please see the buttonholers post (will be added in the future) for clarity.




Perhaps the most important part of everything for the run tests is reviewing the pattern cams on all the machines, and seeing which work and which do not for these machines. And how well they work in comparison to the built in stitches of the same style. I suspect that external cams will be of equal or lesser quality as the cam stacks inside these machines are nearly identical to the external attachable C-style cams, but are made of metal instead of plastic. For a quick visual difference between cam styles see this pinterest link: Cam Styles

With this I have searched high and low for cams. And their numbers are as follows:
1, 2, 3, 4, 5, 6 (there are two different 6's with identical end pattern, but different shapes and I will work with both), 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 47, 48, 50, 53, 56, 84, 85, 86, 87, and 88.

An important thing to note with the C-cams and these pattern numbers are that many of the low number cams are hard to come by because the majority of sewing machines have them built in. For example: 1 is a basic zig-zag stitch, which is standard on most every machine of the C-cam era, but common to see in the E-cam era shortly before.  So having these low numbered cams are often unnecessary.

The unusual thing to note about the cams that are in the 8x range is that they are tri-leveled cams, instead of the bi-level back stitch cams which are numbered 20-56. These tri-leveled cams are for later machines than the ones I am testing, they are for the 198x models an other late 70's models. The third level of the cam has the same general shape as the second level, except it adds a little magnet nub. My guess, because I don't have experience with that is to either allow for a complete pattern and trigger that, or to be a counter. I'll look into those more shortly.

Another thing to note about thes 8x cams tri-level cams, is that the pattern that is on them is reverse of another pattern in the 4x and 5x bi-level range. So you aren't really missing out on anything special.

Please see my C-Cam, bi-level, and tri-level posts for more specifics.

Jane Doe: Discovery

The next 1601 I tested, and the only other one in my possession is Jane. A 158.16011. Right off the bat, I know she's going to take a little bit of work before I can send her on her way one day. Her drop feed sticks. The feed dogs have no problem being up and working, and being down and staying there. But transitioning between the two can be a bit of a challenge. This, thankfully doesn't keep me from doing any testing with her, I just need to make sure I get that resolved between now and October (when I hope to post the machines up for sale) Boy oh boy does she sew. What's that Mazda slogan, "Zoom, Zoom"? She's got that in droves. In a way that I'm actually having the feeling I'm going to have to investigate. Because she flies a bit free after I lift my foot from the pedal. Inertia keeps her going for sometimes as much as TWO whole new stitches. She's a smooth operator/drag racer. A design change I can note between Helen and Jane is the reverse...

To Helen Black: An introduction to 1601s

I'm working with the machines now, not in chronological order, but in complexity order. So the first machine I have worked with is Helen. This bird is a 158.16010. She has a slightly green, maybe mint, enamel casing. Quick things you'll note about her and what basically drew me to these generations of machines is the simplicity of the design. Proof Helen is indeed a machine Basic features that are identical across the 1601/1701/1802 line are the side opening door to get to the light bulb, the easy to remove top (it is just held on with a tension clip around), and the order of the knobs. From left to right up to down, Stitch Width, Reverse Stitch Modifier, Stitch length (with reverse button), and Stitch Selector.  Everything is upfront and easy to access. All the machines I will be testing are flat bed, so to get to the bobbin casing there is either lifting up the machine and tilting it back, or popping out the access plate and hoping your hands are small enough to re...
