The Singer 403 Slant-O-Matic was a sturdy all-metal manual machine that was a star of its day. It combined some of the newest and most advanced features of its day into a domestic machine, making it one of the most popular models available at the time. It is not equipped with all of the functions that are standard in today’s mechanical devices.

On the other hand, it is a real workhorse and it is quite simple to use. It requires a lot of effort and may keep you occupied for a considerable amount of time. It contains various features that you would not expect to find in vintage sewing machines, which without a doubt explains why it is still the victor of its day and why it has stood the test of time.

At A Glance

The Singer 403a Slant-O-Matic appears to be no different than any other vintage sewing machine when viewed in modern times. This piece of equipment, on the other hand, was the most cutting-edge product available at the time it was developed. The slanted presser foot shank assembly had never been considered for use in the house before, and professional seamstresses were the only ones who had access to the myriad ornamental stitch possibilities.

Before the invention of the Slant-O-Matic, slant shank presser foot and front drop-in bobbins were features that could be found on just a select few models of industrial sewing machines. The invention of the Slant-O-Matic made it feasible for all of these benefits to be accessible in the sewing rooms of every single home. It fundamentally altered the method that was utilized by home seamstresses all over the world.

Features

Although the conventional features supplied by the Singer 403a Slant-O-Matic were pretty much unheard of in homes at the time, many of the unique features are now ubiquitous in today’s sewing rooms. The Singer 403a Slant-O-Matic was a pioneer in the home sewing machine industry. They are as follows:

Singer 403 a vintage all metal sewing machine fully restored
  • 9 different kinds of stitches, both practical and beautiful
  • Capability to stitch virtually everything and everything you can think of.
  • Manual for the owner that is concisely written and simple to grasp

Working on the Singer 403a Slant-O-Matic

It is a piece of cake to wind the bobbin on the Singer 403a Slant-O-Matic sewing machine. Everything is very literally within reach of your hands. After placing the thread on the spool pin at the bottom of the machine head, you will need to loop the thread through the guide next to the spool pin and all the way up to the bobbin, which will be positioned on the winder a distance of less than three inches above the thread spool.

After that, the needle motion is stopped by holding the balance wheel while moving the stop motion dial a quarter turn in the other direction, toward the back of the instrument. Then you just need to step on the foot pedal, and presto, your bobbin will begin to wound.
The Singer 403a Slant-O-Matic is exactly as simple to thread as any other model. Just follow the simple instructions that are displayed on the machine’s board, and before you know it, the machine will be threaded and you will be ready to sew.

The fact that double needles were not yet available for use in domestic settings when the Singer 403a Slant-O-Matic was being produced did not deter the maker, however. In addition to having the capacity to use two needles at once when sewing, this machine also provides the user with the option of choosing between three distinct needle positions. Turning a dial and moving a lever to the correct position are all that are required to make adjustments to the needle position, as well as the stitch length and breadth.

It may be because I’m used to being able to pick decorative and utility stitches with just a touch on an LCD screen or by calling up a desired stitch on a keyboard, but I found the process of selecting stitches on this machine to be a little bit of a chore. I think this is because I’ve been spoiled. In order to produce the required stitch, in addition to inserting the disc, it is also essential to make a few modifications to the stitch length and breadth, and in some instances, even the needle plate.

But because I was working on the first home sewing machine that had any decorative stitches at all, I had to confess that I was fascinated by the diversity of stitches and the ingenuity it needed to build such an inventive machine

In fact, I was working on the first home sewing machine that had no decorative stitches at all. Taking everything into consideration, this device is more than half a century old. When you think about that piece of information, it’s not only incredible to think that all of these firsts were jam-packed into one sewing machine, but it also compels one to take a second look at what we may refer to as a challenge. When you think about it that way, it’s amazing to think that all of these firsts were jam-packed into one sewing machine.

As difficult as it may be, we really have to think about the fact that the Singer 403a Slant-O-Matic is the groundbreaker that it truly is and then reconsider our criticism about the stitch selection process. Luckily, the owner’s manual was available. With the manual in hand, I was able to use it as a guide to do the different stitches with the least amount of trouble. What may be a challenge for the 21st-century home sewer was no doubt a dream come true for the home sewer of the mid-1950s.

My complaint about having to take time to change discs and machine settings just proves how spoiled we have become in just a few short years. With that in mind, and my own inability to get the hang of going through so many steps to achieve different stitches, I must admit that the stitch quality is excellent… better, in fact, than some of the newer machines I’ve had the pleasure of reviewing.

Accessories

The following items were included in the accessories case that was included with the Singer 403a Slant-O-Matic when it was purchased:

  • 8 Presser Feet
  • Straight stitch
  • General purpose
  • Special purpose
  • Button
  • Zipper
  • Rolled hem
  • Multi-slotted binder or bias tape foot
  • Ruffler
  • Seam guide
  • 8 Drop-in fashion discs to give the user access to various decorative stitch options
  • Lint brush
  • Screwdriver
  • Oil dispenser
  • Extra bobbins
  • Extra needles
  • 2 needle plates
  • Owner’s instruction manual

In addition, the optional presser feet listed below were also available at your neighborhood Singer retailer:

  • Darning and embroidery – This one is very much like the darning foot that is used in the 21st Century.
  • Tucker – I have to confess that I have never seen a presser foot that looks just like this before. This strange-looking attachment actually contains two distinct gages, one for measuring the distance between tucks and the other for determining the size of the tucks themselves. The instructions state that users have the ability to produce tucks that are up to one inch deep with professional precision.
  • Gathering – Although it is referred to as a collecting foot, its primary function is in fact that of a shirring foot. Any person who employs this specialist foot will be able to manufacture “single or multiple rows of shirring” professionally and swiftly, as stated in the owner’s handbook.
  • Edge stitcher – The illustration that is included in the owner’s handbook looks nothing like the edger stitchers that are available today, but the end effect is essentially the same. This presser foot is utilized for the joining of fabrics, the insertion of lace, and the stitching of French seams, which is a method that is becoming increasingly archaic.

A set of 12 more fashion discs is also available as an extra optional accessory. This brings the total number of decorative and utilitarian stitch possibilities available to a grand total of 21.

The Brother CS5055 Computerized Sewing Machine, which is newer and more advanced than its predecessor, the Brother CS5055PRW, has since been discontinued.

The CS5055 has a total of 60 built-in stitches in addition to 7 buttonholes, however, the CS5055PRW only has a total of 50 built-in stitches and 5 buttonholes.

In addition to that, its needle threader mechanism is much improved. The dial for adjusting the tension is moved to a location that is more convenient to the stitching area, and the bobbin case snaps shut in a slightly different manner.

It is a completely automated sewing machine that makes use of the most recent sewing machine technologies to make stitching much simpler.

Selecting stitches is a piece of cake because of the uncomplicated nature of the buttons and the lucidity of the LCD screen.

This machine is equipped with a presser foot lift, an auto-declutch bobbin winder, a needle threader, and a stitch width of 7 millimeters that may be set manually. On the LCD display, you will also find buttons that let you move the needle up and down, as well as a button that locks the stitch. When quilting or sewing with a high level of precision, it is helpful to have a start/stop button located immediately next to the needle.

This machine does an excellent job of sewing up little holes or hemming a pair of pants to the appropriate length. The reverse button offers a number of benefits, one of which is the ability to reinforce seams.

This piece of equipment comes with a storage container that can be removed, which is really convenient for when you need to store things. Janome’s 50-stitch sewing machine provides users with the assurance, accuracy, and durability necessary to successfully accomplish their sewing jobs.

Tying Off The Loose Ends

Even now, after over 55 years, the Singer 403a Slant-O-Matic is still widely regarded as one of the most trustworthy and durable sewing machines now available. Changing fashion discs and machine settings is a time-consuming and even difficult process. However, the fact that this sewing machine is the first to feature front drop-in bobbins, slant presser foot shank construction, and a multitude of utility and decorative stitch options makes it a machine that is worth considering.


The Singer 403a Slant-O-Matic that I examined is only available for use in the sewing lessons offered by Think Outside the Store in Silver Spring, Maryland; it is not for sale to the general public. Finding one that is available for purchase is probably as difficult as trying to find the proverbial needle in the proverbial haystack. However, this does not imply that finding them will be an impossible task. I was able to purchase it via eBay.

The asking price was $224.95, which is a monument to the value that has long been associated with a machine of this era. Sewing machines that were manufactured by other firms around the same time period and are about the same age are typically offered for sale at substantially lower prices.

A further advantage is that it is manufactured by Singer; hence, anyone who buys a 403a Slant-O-Matic will have access to the technical support resources made available by Singer. This machine may be serviced and repaired by any authorized Singer dealer or repair specialist in exactly the same manner that they would service and repair a brand-new Singer sewing machine or Singer serger straight from the box.
