What is a Heavy Duty Sewing Machine?
A question that we see often in the sewing community is: “What is a heavy duty sewing machine?”
Simply put, a heavy- duty sewing machine is a sewing machine designed to sew heavy duty fabrics.
It is the real workhorse for heavy fabrics. It can work daily without burning out.If you’re new to sewing or even if you are an advanced sewist, this article will help you better understand what a heavy duty sewing machine is and what they are used for.
More specifically, we will cover:
- What a heavy duty sewing machine is
- The best type of needle and thread to use with heavy duty sewing machines
- A list of recommended needle sizes for heavy duty sewing machines
- 10 Types of Sewing projects that Require Heavy Duty Machines
Let's dive right in.
How Does a Heavy Duty Sewing Machine Differ From Lightweight Sewing Machines?
Well for starters, heavy duty sewing machines are used to sew heavy duty fabrics. This includes fabrics such as denims, canvas, leather, mattress, upholstery and polyester.
Oh and here's something else worth noting:
These sewing machines are also equipped with stronger motors that will help you sew garments faster.
Whereas smaller light-duty sewing machines like this Singer 3232 portable machine are a bit slower.
How Do Heavy Duty Sewing Machines Work?
The heavy duty machine is also different in the way that it works. It has some automated functions and features that you may not find in basic sewing machines.
For example, the machine has a self-lubricating function. This is a good thing because bigger sewing machines require lubrication more often than the smaller ones.
Secondly, heavy duty sewing machines also stitch at high speed. For example, some of these machines like the Singer 4452 Heavy Duty Sewing Machine can sew up to 1,100 stitches per minute.
Talk about a true workhorse!
This is about 4 times faster than a small sewing machine that can do only 750 stitches per minute.
Compared to a home sewing machine, a heavy-duty one is quite versatile. It can be used for special tasks such as quilting, monograms, buttonholes and blind hems. All these are heavy-duty sewing jobs that would be harder to do with smaller machines.
What Type of Needle Should You Use with Heavy Duty Sewing Machines?
A big part of your sewing success with heavy duty sewing machines depends on several things. One of these things, perhaps the most important one of them all is the type of needle that you choose.
With heavy duty sewing machines, you will need to use a heavy duty machine needle.
Here’s the thing:
To an untrained eye, a needle is just about how thick and how long it is. However, in the sewing world, a needle has different parts.
In this section of the post, we will give a brief breakdown of these parts and explain what they mean.
The Anatomy of a Heavy Duty Sewing Needle
Here is a quick breakdown of the parts of a sewing needle:
- Shank – This is a flat back and round front of the needle that goes into the machine. The machine holds onto this part and keeps the needle upright.
- Shaft – This is the part immediately beneath the shank. This is the part that determines the size of the needle.
- Front groove – This is a small slit located above the eye. Its work is to hold the thread in the right way for better stitching.
- Point – This is the sharp part that penetrates the material that you are sewing. It is also the part that is responsible for passing thread to the bobbin hook to make a stitch. Points come in different shapes depending on the material that you are sewing.
- Eye – This is the small hole where the thread will pass. If you use thick threads, you need a needle with a bigger eye and vice versa. The most important thing is that the eye should allow the thread to pass through easily.
- Scarf – This is a small indentation that you will find at the back of the needle. The importance of the scarf part is to ensure there are no skipped stitches. If you have a precisely-timed machine, use a needle with a shorter scarf. If not precisely timed, use a needle with a longer scarf.
Why It’s Important to Use the Correct Needle with Heavy Duty Sewing Machines
If you use the wrong needle, a lot could go wrong. Some of the issues that you can potentially run into include:
- Damage or even breaking the bobbin hook
- Making low quality stitches
- Making the wrong seams
- Creating unsightly holes in your fabric
- Tampering with the machine’s timing
Before choosing a needle for your heavy duty sewing machine, there are a few things that you should consider.
For example, you will need to think about the thickness of the fabric. The heavier the fabric, the thicker the needle you will need.
Your choice of sewing machine needles also depends on the type of stitching that you want to do.
Recommended Needle Sizes for Heavy Duty Sewing Machines
When you start using heavy duty sewing machines for your sewing projects, you will need to familiarize yourself with the needle sizes.
The most common needle sizes for heavy-duty sewing machines include the following:
Type of Fabric
For medium heavy fabrics like corduroys
90/14 needle size
For heavier fabrics such as Duck Cloth and Denim
100/16 needle size
Fabrics such as tapestry or canvas
110/18 needle size
For the heaviest fabrics such as boat canvas
120/19 needle size
One of the best places to get affordable and heavy duty sewing machine needles by far is Amazon.
They have a ton of heavy duty sewing needles that you can use for a wide assortment of sewing projects.
What Is the Best Heavy Duty Thread to Use?
When it comes to choosing heavy duty threads there are a few things to be aware of. For starters, thread sizes are measured by numbers. The higher numbers indicate heavier threads. Lower numbers equate to lighter thread.
It's easy to assume that you can use any type of thread that you find in stores with a heavy duty sewing machine. However, this is not the case.
Threads with cotton and polyester will help you sew denim, double knits, drapery fabric, leece, leather and faux leather, quilted fabrics, and upholstery with much ease.
