Singer Heavy Duty, Most In-Depth Review on the Internet. No Really, I'm Not Joking. 

Great job Wes! Well done, & unsponsored too! These are exactly the types of videos sewing enthusiasts want to see to make a buying decision, especially on the lower priced sewing models. I, personally, would like to see comparisons and “Tear Downs”, specifically, big box brands vs dealer brands, comparable machines tested against each other, to see if the public is getting what they pay for in quality and durability, & long term expectancy. Finally, your professional opinion, and experience with issues you have seen with repairing these models at all price points. Point out the average price for particular machines, and is the cost a reasonable price for that particular machine. KEEP MAKING THESE KIND OF VIDEOS! Well done! 👍👍👍👍👍 (5 Thumbs Up) My highest review rating!

I repair/rebuild 300U Chain stich machines daily for a very large mattress co and I just got to say my hats off to anybody who can tear a sewing machine down to the frame and reassemble it. With the end result being a fully functioning head.

I just bought this machine prior to watching this. I like the edit and angles. No fluff just good info.

You solidified my decision about buying this machine. I was looking everywhere for info about upgrading the motor to sew heavier materials. Your video is the ONLY place I found this info. Thanks!

After both my expensive electronic machines began having issues I started looking for something a little more basic. No more electronics. This was the best video review I've seen. I bought this not expecting to love it, but after a couple of months using it I do. It works and works well. I really noticed the difference when I was sewing over a thick spot of multiple layers. My old machine would have balked, but this little Singer sewed it with zero drama. I was always sort of a sewing machine snob. I hated my first singer so badly I returned it and wouldn't touch a Singer product. 40 years later I've finally bought another one, this one, and I love it. Thanks for all the time you put into doing this video, was a real help.

Broski, your video totally solidified any doubts I had about my recent purchase as I am proud to own a serviceable machine these days. Hats off to singer & the crew that makes this channel possible! Cheers!

Thank you Wes for the in-depth review of this machine. I bought this exact model in February and REALLY like it. I'm glad to know that the machine truly is a heavy duty one!

I have had my Singer Heavy Duty a couple of years and love it. Your video really explained how it works very nicely..thank you ! I'm glad I bought mine ! Your videos are great !!

Thank you. I had looking at this machine for a while. After this video my husband got it for me for Christmas. It is a dream to sew on!

Makes me feel much better about my purchase. I sew a lot of hooded towels and my old Singer Future 100 just couldn't handle it anymore.

Appreciate your videos! So thorough! Especially thankful for this one and other peoples comments! Hope to get years of service and many projects done with this one.

This is by a large margin the best sewing machine review video I ever came across. Dense information, conveyed in a minimum of time - excellent use of bandwidth 😉 Being a fan of old Berninas (105, 114, 117 K&L) and Singers (206G and 316G) which I love for their indestructible sturdiness, smooth operations (specifically the Berninas with their rotating hook 🥰) and absence of plastic (except for the 316G's fashion discs - what were they thinking when constructing it?) I was considering something more modern and back friendly when lugging it around. You answered practically all my questions with regards to the Singer 4432 HD in one go and gave me confidence that I would not waste my money on one (being ~ 10 times more expensive than what I usually pay for my old beauties). Excellent job, one follower deserved and gained 😅 ... please keep up the great work!

This is very helpful. I've owned a 60 year old heavy duty Singer 328k for the last 50 years. and it's never given me a moment's trouble. I just ordered a Singer heavy duty 4452 and hope it does as well.

EXCELLENT ! Much more detailed than I expected . I rebuild small air compressors and appreciate your showing the individual parts within the Singer . Nice to know before making a purchase that this will probably do the job. I don't have the experience in using a machine as does Tracy , but ..... here goes ! Good job !

Thank you so much for this video. I bought this machine about a year ago and I've had no issues at all from lightweight to heavy and it sews like a champ. I have a 30 year old Viking Prisma and it beats it even for lightweight fabric. A friend recommended it to me since I sew just about everything from clothing to quilts and this little machine works great.

Your fantastic in depth videos are exactly what sewists of any level of experience need. For beginners to start their journey with a healthy knowledge of maintenance can only be a good thing, as well as giving them the confidence to sew without fear of the unknown. I have successfully stripped my Brother FS130QC, (that I've had for many, many years) cleaned, oiled, and reassembled to full working order, and I have you to thank for that.

I read a lot of reviews, before buying this machine, two years ago. I have owned numerous machines of all makes over the years. I like this machine. I'm glad I chose it. I chose a manual specifically to be able to maintain it myself. I have done some oiling and cleaning on it, but after watching this video, I will do more. I'm very thankful for your video. I mostly make fancy doll clothes.

Thank you I bought one yesterday and learning how to use it for the purpose of fixing my sailboats sunbrella enclosure. I feel encouraged now that it will do the job. God Bless You.

As an engineer who sews stuff.....this was a really informative review. thanks.

Outstanding review! I bought one of these machines HOPING the Singer name still stood for quality. Your effort here was enlightening, thank you!

Thank you for taking the time to breakdown and explain through your knowledge of the mechanics of the machine. I'm a newer machine sewer (with a few hand sewing projects under my belt) and am hoping to purchase a machine that will last through a wide variety of projects (home and clothing). I've been debating between a used singer heavy duty or waiting to snag an older, all-metal sewing maching. This is definitely super informative and helps me be more informed as I figure out my options.

You, sir....are the MAN!! Ripped it down, and put all the parts and pieces back together! Thank you for easing my mind with my purchase!

Personally I would spend your cash on a pre-1950s Singer that's had a good service. They are built to a MUCH higher standard and will give good service for generations. They are simple, bombproof machines that you can service yourself if you are at all handy - the manuals are available online and parts are widely available.

Thank you for doing this video. I needed to know if this machine was heavy duty. I have this machine and I do like the way it works. Not knowing enough about sewing machines left me kind of doubting if it was heavy duty. Happy about the results.

Thank you so much! I really appreciate your video. Im currently looking to replace my sewing machine, i was hesitant to buy this machine to begin with, because of few video reviews i saw on youtube. Mostly because of the plstic exterior. Nobody does a depth investigation and review like you did. This is very helpful and fair review, and im so grateful to find your channel. From the bottom of my heart, im thanking you very much.

Excellent review. Thank you. Would be great if you looked under the hood of other machines too. It was great to see where the secret screws are! I tried to strip my pfaff but couldn’t get case off. And you can’t clean the tensions discs with it on. But you’ve given me an idea now !

I’m so glad I watched this video on Singer Heavy Duty machines. I just bought a second-hand Singer HD. It ha been serviced and seems to sew well. Now that I’ve seen your video, I am especially pleased with my purchase. Thanks for all the great info.

Excellent! My wife doubted that this machine I bought for my craft work was really "heavy duty." This review helped me have more confidence. Thanks.

Looks more well-built than I expected. Those gears on the motor shaft usually have a hex head set screw and motor shafts are pretty much universal so you can switch it as long as the relative position from where the motor mounts is the same. Very nice for a modern machine but I'll stick with the Pfaff 130-6 that I beefed up significantly.

Makes me very glad we still also own a 80 or 90 year old tradel machine! That baby never stops running!!!

Thank you for your thorough examination and investigation of this sewing machine. May you and your ministry be blessed.

Great video!! It's good to know there are some modern models that can be maintained without breaking all of the plastic that holds them together. Thanks for sharing.

The belt is called a toothed belt operating on the toothed pulley on the motor. They have exceptional life expectancy and transfer power better than traditional gears and shafts in the older machines.

I wish you were in my country so I could get you to service and upgrade my machines. I wish you more success

I have had my machine for over a year and have no problem at all with it I didn’t know where to oil it thank you for showing me

Exactly what I needed to see, love the technical aspect of this review. Understand the electronics better than just words

Very informative and interesting. You have helped me to decide which machine to buy and it will be this one. Thank you 🙏 xxx

Thank you very much for taking the time for this video. As other people said, we are trying to get a better machine, as a heavy duty that can sew several layers of vinyl and others. I was watching some videos about the ST371HD from brother, it will be very interesting if you could show us in the same way if it is a real heavy duty. The brother has the possibility to lift the needle bar a little more than the singer and the other domestics so it will be important if this comparison could be done. I'm sorry if my english is not so well, I'm from México city, thank you very much

Great video. My in laws bought me this machine a few years ago so I could repair denim and heavy work clothes. From my experience this machine is a real workhorse. After watching this I can see why and I will make sure to open it up and maintain it well.

Excellent video! I am currently shopping for a heavy duty machine for some upholstery work and I am so glad I watched your video. I was really excited to see the tear down and where the machine needed to be oiled.

Great review. That was my first machine. I had it for 4 years and just this week upgraded to a Janome with auto thread cutter and so many other upgrades. I will always love this singer and highly recommend it to a beginner to sewing. Thank you for sharing scripture too. God bless!

The stainless steel bed cover is to help fabric glide across the bed and withstand scratches from pins better than plastic.

I so appreciate your videos. I’ve been able to “fix” my machine a few times by watching❤

Thanks for this. I was watching videos on how to use this bugger and stumbled across yours. I think I made an OK choice. I bought mine at Walmart and just need something that will hold up to everyday type sewing. I doubt I'll ever need to sew more than 3 layers of leather! I love that mine has the needle threader. What a treat after all these years of threading sewing machine needles. I'm saving this for when I need to oil the beast. Without spending a fortune I think this is as close to what I learned to sew on back in the 1970s - no real bells and whistles to cause problems. Again, thank you!

Excellent review, thank you for the in-depth break down. I have this machine and like it. Gets the job done and versatile for its price point. It is still too plastic compared to what Singer used to manufacture. Everything is produced to lower costs as much as possible sacrificing long term quality. They just won't last 20+ years as the older models. Plastic gears/parts lasting 'a little bit' doesn't cut it - it wears down over time. 'Plastic' and 'gears' should not be in the same sentence. I bought a used 80's vintage Singer machine with a dozen basic stitches, is built like a tank, and even where plastic casing is used is hard and beefy compared to my 4452. No plastic gears, all metal-on-metal mechanics. If the timing becomes an issue, I can fix it. Cleaned and oiled it runs as new. My friend still uses the family's 1960's vintage Singer which works as well as it did brand new. Occasional cleaning/oiling and it keeps going. High quality.

WOW This is the first time I have watched one of your videos ... it will not be the last! I am a researcher. It will take me 6 months of research to make a decision, but when I do, it will be A GOOD DECISION. You just saved me 6 months. You are so precise and thorough, I am ready to buy. Please stay true because we need honest, unbiased reviewers like you

I was dying to see inside of my machine! Thank you so much my husband really appreciate!

Thank you, your video helped me to repair my own Singer, I couldn’t figure out how to open it. Your video demo really made it easy for me!

Very interesting and informative and also great video presentation. Not in the market for a machine like this, but would feel comfortable recommending the model next time someone asks. I'll also recommend your video! IMO this would be a great starter machine for anyone with little or no experience. Thank you!

I just purchased the 4432, which I was told is the same as the 4452. I enjoyed learning from you that the machine is heavy duty.

Thank your for the information. I have been using this machine for years and love it. I also have a $6000.00 Viking electronic embroidery machine that has cost me many hundreds of dollars for maintenance and for a power supply. It needed another power supply a year after the last one was replaced. (Which I have not replaced. And yes, it is on a surge protector.) It now sits on the floor in my sewing room. The Singer is constantly used and works fine. Thank you for letting me know how to oil it. Update - I just finished cleaning and oiling my Singer Heavy Duty. Thank you so much for saving me a lot of money.

Thank you for this review. I had seen a sewing content maker criticize it as being in repair shops a lot & that Singer isn’t same quality since it’s changed owners. I’ve been very happy with mine, and the only times where stitch knotting or tangle happened got fixed by adjusting tension and stitch length.

I'm using this machine now and i love it! 😍 worth the money spend

To test for aluminum or zinc, use a drop of vinegar. If it discolors, by blackening, its aluminum. :)

Its 2 years later and I bought one of these. I did not use it for some time. When I did the bobbin kept grabbing and breaking the thread. Im sure its me because Im not familiar with the machine. The video really helps me. I was worried about my machine being frail but obviously I dont have to worry too much. Thank you so much for leaving this up.

Wes, I just found your channel and wanted to say thanks for the videos. This is the kind of information that I want to know about different machines. Thanks!

These are the type of videos that I would like to see for all the sewing machines

I’ve had one of these but swapped it for a Singer 201K and I’ve never regretted it. The latter is my pride and joy and will last generations to come!

My singer heavy duty will be here in a couple days and I'm so excited, first machine ever!! Thanks for the awesome video. Its really neat to see what it's all about

Thank you so much. They was an awesome review. I just ordered one!

I have this machine and love it so much more than my Eversew 30 sparrow.

This was the video I have been looking for! I bought one of these machines on Black Friday sale a few years ago on Amazon and hate to say how much cause they really came up in price! I originally bought it thinking if I killed it it would be less than repairing my beloved (now vintage) Pfaff creatives (1472 & 1472CD) to sew heavier projects cause I know my baby’s limits! Well, almost 6 years later it’s not died and I and anyone I loan it out to have become big fans of this machine. I take it to sewing get togethers (when we could get together) because it is lighter weight than my Pfaff 1472. It’s not fussy with tension and honestly I’ve barley messed with the tension from lightweight chiffon to Sunbrella. The stitch length is a big one to increase for heavier items. If I were still teaching sewing I’d use/recommended this machine. Now, I have used it on multiple layers of denim for an art exhibition and it did a good 95% well. If I could get it under the needle it sewed it. Don’t break needles as much as getting stuck. But you do have to watch out for the darn presser foot (which I hate) as I find it’s easy to get hung up on something. I’ve done boat Bimini’s on it. Well, let’s say it was NOT enjoyable doing 2-4 layers of Sunbrella but again. It didn’t die. When my man wanted his vinyl Dodger windows replaced I told him I did need an actual industrial machine. I could try a sample but they don’t have the muscle to get through some marine fabrics. Now, overall. I do love this machine. Does she have as beautiful of stitch as the vintage Singer 95? No. But the 95 is hard to beat. I’ve had friends want to buy it but she’s a keeper! Oh, that actually might be another good video. Test a Singer 95 against the heavy duty. Another repair person told me the 95’s were the strongest domestic machines ever made. If you couldn’t see it on them, you need an industrial. I’ve got one and it’s a little tank. I’d also love to see a Sailrite review (haven’t checked your other video yet but will now)! We bought one for the Dodger window project and it made such a difference that they turned out so nice, I volunteered to do the rest of his windows! And I HATE marine sewing!!! But man, that machine had the muscle to get through those layers like nobody’s business. Mine won’t win any speed contests (think you can get a monster wheel or table setup) but it’s not about speed but the muscle to get through some nasty layers (2 vinyl and up to 4-5 Sunbrella) all without a gruff.

I'm new to sewing. I bought my Singer 4423HD about 3 years ago. I've sewn many western shirts, blue jeans and even leather cellphone cases with this machine! I've also repaired nylon winch and tow straps (using the proper needles and thread of course!). I've had a chance to use a few sewing machines and I must say this Singer makes the best straight stitches of all. Since I have no need to do embroidery or other fancy stitches, this little analog machine has served me well! I am diligent about changing my needles and keeping my machine oiled and cleaned. As you pointed out, no need to remove all covers to reach the necessary maintenance points. Good job and thanks for the great video!

I AM SO GRATEFUL FOR YOUR WORK!

I have one of these. I accidentally sewed through the metal head of a safety pin with it. Literally punched the needle right through it. So I guess it's pretty heavy duty. My only complaint is the plastic housing above the needle is very cumbersome. All of my machines before this one were Singer Touch & Sews, so I'm used to the area around the needle being open and easy to access.

This video is awesome, just what I was looking for. Thank uuu

Thank you, for the recommendation. Your videos are super informative and straightforward. Much appreciated 🙏

I don’t own one yet, but this is the one I’ve been eyeing and you just convinced me 😊 very good information,Great video! Thanks.

Thanks to your example, I'm not going to break the plastic tab off the top plate. Thank you. Great video.

Great review Wes, thank you. What I really valued was that your opinions are backed up by data and hard facts. I love watching reviews but sometimes they're just subjective opinions (which is fine), but the real value is in data. Look forward to seeing more from you. Incidentally, it wouldn't bother me to know you'd taken a machine on loan for a review - it's whether your audience believes you objectivity. Kind regards from North Wales UK

Great video and thank you! I just received a refurbished one and look forward to getting back into sewing after many (many) years!

Very informative. I am getting a HD 110 and this has been exactly what I wanted to know about the Singer HD series. Thanks for posting.

Great review. I've seen 2 of your other trouble shooting vids. Am a new subscriber now! Cheers from NZ P.s...if you do a part 2 ...could you inc. a vid of you actually oiling the bearings, felts & pivot points where you'd expect to maintain, as well as the places to clean out lint/dust - to keep machines running for years.

Good morning and thank you for taking the time out to give us a very in-depth review! I really liked that you opened the machine up and talked about, what is plastic and what is metal. The last couple of days, I've been doing research and reading reviews about this machine and I was really skeptical. But, after watching your breakdown of this sewing machine, I am ready to purchase! Thank you again and God Bless :-)

Great Video. I own a 4452 & I learned A LOT from your video. We are a small ( at this time ) startup company & we're using this machine. We are sewing terry cloth, vinyl, & pet screening. So far, the machine is holding up well, but ? This video has given me the confidence to go inside for R&R. Thanks !!!!

I love your vídeos, thank you so much for your patience, time and good humor. I would love to learn how to desassemble, oiling and greasing a Singer Heavy Duty 6800c. I hope one day in the future I will learn with you. God bless your heart.

Great Job! good info....about this Machine ..I own one and was wondering about the authenticity ...and truthfulness about its being called a "heavy duty" machine!

Singer just came out with a digital version of this heavy duty machine. Please use that one as your computerized test subject.

Thank you for this review! I have had my eye on this machine for quite some time. My sister owns one and loves it. But I’ve been a Singer lover since the mid 1960’s and own a 1963 T&S with all metal gears. That machine, is what I would call heavy duty for a home machine. It’s gone back and forth across the US four times, with all but one time in a car. The fourth time, it fell off a conveyor belt while being loaded onto a plane. And it’s still running. I think the term “heavy duty” by today’s standards means that it’s not all plastic. Cheap soft metal, sure, but no plastic.

WOW! Thank you for taking the time to do this for us! I am going out TOMORROW to buy one!

Love the scripture! Nice surprise! Great going on the heavy duty singer too, thank you.

so glad to see so much metal inside this machine. glad i made the purchase, now to open it and use it.

I just purchased this machine from the Singer web site and I'm waiting for it to be delivered. They were having a Labor Day sale, so I snatched it up for $223, and that includes tax. I'm a novice at sewing, so I started off with an inexpensive Singer Start 1304. After 2 months, my projects have become more than this beginner machine can handle, so I had to kick it up a notch and purchase the heavy duty machine. Thanks for the review. It makes me more confident that I made the right decision in the purchase of this model.

Wow. Hats off to you. Thanks for sharing the insights and practical review

Thank you so much for this review. Very impressed with your skill, method and presentation. My hobby grew to a small business size, and I now do lots of curtains. Mostly hand finishing, but the pleats are giving me grief. 2 plies of heavy damask or thick wool. lining, interlining and buckram - the sheer bulk of it is difficult to get under the foot, not to mention sew through, even though it is not as challenging as leather or canvas. Do you feel that this machine would be a suitable all-rounder, for the curtains but also for "normal" sewing? If not, could you be kind to recommend some machine models under 800$/500£? Maybe vintage? Does such a beast even exist? Thank you very much in advance!

Absolutely the MOST In-depth Review and pleasant to listen to! You've given me assurance that this model would be a good buy for me and I appreciate that. You are a good teacher/demonstrator and your camera work is excellent! So thank you, I'm subscribing and I hope your channel blooms and grows :) Surely Singer should sponsor your singer videos.

Thank you very much for this incredible review, really helpful and inlighting for me, I was looking for some proof of what is inside before purchasing this model. Also it gave me the confidence that, with basic maintenance, it will outstand the test of time; I don't wish to make a habit from buying sewing machines :D. Thanks again!

Thanks so much for this review! I’ve been looking for a new machine and wanted a heavy duty but you can’t go by the ads.! Also, thanks got the scripture!

Amazing what heavy duty means these days for all kinds of machines. Soft metal, plastic gears, plastic covers. Even someone has to disassemble it, so the customer can see if it is actually good and repairable. Heavy duty now means that it is barely good enough, instead of actually be strong and reliable for many years.

If I may make a video suggestion, I would like to see a video about servicing a few common modern machines, specifically the brother SE400/600, and its embroidery only counterpart, the PE770/800. I have noticed that these machines are very popular online, but little (quality) content exists on repairing or maintaining these machines, especially for common problems or adjustments. The only such detailed videos I can recall are those from Vince J Auri, who seems to know a lot about the machines, but has poor filming and editing. I think that is a good opportunity to attract some serious long term views for your channel.

I'm considering buying one of these, so I'm glad to see that it's intended to be maintained, but I naively assumed that all machines would be! Terrible that any manufacturer would make machines without easy access for basic oiling. Though having said that, I don't see any maintenance instructions in the manual for this one, other than how to change a needle, which is hardly "maintenance"! Lucky there's youtube. Thanks for the comprehensive teardown! :)

Just got this model and it jammed on me in the first two hours. You can hear it run but the needle nor the bobbin loader spins. Very helpful to see a proper disassembly.

Hi- Thanks for another great video! At exactly 12:50 in the video your finger is pointing at a metal piece next to the bearing, that has what appears to be 2 small felts. There is a 3rd felt in the part behind that metal piece. Are they to be oiled, and if so how much?

There's also thin felt pads on either side of the motor bearings inside the motor plates with holes in them. Most people miss this. Maybe some shops. Must be careful only to add a very little bit.

Excellent review - I’ve used old Singer machines (1950s), and I even have a hand operated Singer - not easy if you’ve got a lot of sewing to do! Now I’m trying to decide what to buy for a new machine. This looks like the one😀. Your comprehensive review was really useful - thank you!

Nice job! Thank you. I have two of these machines.love them both!

40 HRC will scratch even some mildly hardened steels. Your kit is for hardened steels only. The chasis is not zamak, but it's not pure aluminum either. It's made of silumin, composition of aluminum, sillicone and additives. It can containt up to 25% sillicone, which is basically sand and is dirt cheap, so silumin is cheaper than pure aluminum, but it's also slightly stronger at the cost of greatly reduced plasticity. You can't bend silumin or it will break.

40 HRC isn't soft. The Rockwell hardness C scale goes from 20 - 75. 4140 medium alloy steel normalizes to ~ 30 HRC. 4130 alloy steel normalizes below 20. If it attracts a magnet the metal is steel.

thanks for the instructions regarding the top cover! you saved my day!!!

I’m impressed by this video. THIS is RU-vid at its best!
