Thank you so much for stopping by and I will see y’all on the next video!!
I recently purchased one of these machines and thought I had been taken. Ran terrible, rubbing metal, hard to crank. I saw our video and took it completely apart, did a lot of grinding, polishing, greasing and adjusting. Now it runs very well and smooth. Thank you for teaching me how to improve it.
Thanks for your support and I am glad I could be helpful.
Yes they need lube and running in and a little blueprinting never hurts.
I just wanted to say thank you so much for taking the time to make this. I watched this once waiting for it to arrive, and a second time to actually reassemble it and make sure I didn't miss anything (I did). It's hard to describe how big of an impact a proper cleaning and greasing can make. This went from a crunchy, sticky, barely functioning machine - practically speaking it would be unusable, to something that operates buttery smooth and feels like a robust machine made before planned obsolescence. Like I just found a treasure in a thrift shop. I never would have been able to get this back together, or even have had the confidence to take this apart if not for this video and I'm extremely thankful for it.
To anyone considering doing this, or on the fence, if you've already got a dremel and some spare elbow grease this is definitely worth it! Other than saving a lot of money, the hidden benefit of DIYing this machine vs buying a far more expensive machine is that you also end up learning how every piece of it works as you put it back together - so maintenance in the future will be a lot less daunting and quicker.
Again, thank you so much!
Just got my machine in yesterday. Been watching your videos before committing to purchase. You have been an absolute wealth of information. Thank you so much for your time and videos!
No worries, I am happy I could help out
I just unpacked my machine, was scratching my head on where to begin and ran across this video. Now I have the confidence to disassemble it, because you showed me how to reassemble
and time the thing, Thank you so much!!
I have to tell you ... out of ALL the video tutorials i've watched re; "Chinese Patcher/Cobbler Machine" ... you SIR! ... are the best, in-depth, most knowledgeable, detailed oriented, troubleshooter regarding these finicky machines on RUclips or on the Internet for that matter ... Full Stop! ... Thank You!
Wow, thanks!
Really appreciated the step-by-step instructions on this video. I was able to completely disassemble the machine and successfully reassemble it because of the information you provide. I typed up the steps for my own sanity but had to keep referring back to sections on the video to watch how some pieces fit back together. Thank you very much for going to the trouble to make this. Very helpful.
New to CLSP and your channel but love your concise narrations. For springs, I suggest getting 12 inches of heavy thread, stick it through the end of the spring, fold thread in half and pull up on the string to stretch the spring onto its post (biker trick). Also, while apart, get a cheap tap set with the 4 smallest metric threads ($5) and run all threads on all parts. Experience has taught me that when a Chinese manufacture uses the same taps 50,000 times, the threads they cut are BAD. My bobbin cover screw came with damaged threads and the hole had no clean threads. Tapped it out, got a longer screw, put in a drill and reduced the screw head diameter and taper to make it more counter-sunk and smoother on top. Also used bright heat shrink tubing on foot lift lever and sewing head swivel ears. Easy to see and gives them a rubber-like coating.
BTW, thanks for all of your videos. You are one of the main reasons I went ahead and spent $100 when I already have machines costing much more that are motorized, finely tuned from the factory and are ready to go. I am in the process of reassembling my newly arrived patcher since I like to tinker. Your videos, and now this one especially, are extremely useful for knowing how to operate and tear down/reassemble these machines. I figured I would do a top-down fine tune up before really even trying anything.
Keep up the good work and information sharing. I appreciate your passion for creating and sharing, especially on this machine.
I'm on the reassembly phase after polishing and painting. After watching this video (based on your years of experience with the machine), I'll be cleaning off and re-lubricating with grease especially in the sewing head.
GOAT u are. Best videos on the Tube! Thank You Sir!!
It seems like most people have the attention span of a goldfish these days...
I was so glad to see someone that would go so in depth about what craftsmanship is all about.
From a fellow tinkerer, thank for your time brother...
I absolutely enjoyed this , and I needed to know all of what you went over , thank you so much
great vid..you have no idea how much the community depends on your videos...thank you so much!
I know this video is a couple years old but I just brought one of these machines and I'm waiting on it to arrive. While waiting I'm trying to learn as much as can be learned by watching videos. I'm an old dude, 73 and just filling time till it's time to go home. Thanks a bunch for taking the time to share what you have learned. May God bless.
Thank you for your comment!! If you run into any issues feel free to send me a email at mainelyacres@yahoo.com
Just found these videos and they are extremely helpful. Now for me to polish my machine.
Thank you for putting this all on one video. It drives me nuts when someone will break their videos up into pieces what should be left whole. Too much of a pain to find them all and gather them up into a cohesive and coherent block of info. There are hundreds of videos about this machine on RUclips. I've watched dozens of them and I must say this is by far the single best video on the CLSP that I've seen. Some guys will present solutions that are unfeasible for the average DIYer, casting, forging and machining parts from scratch. Others who pretend to know what they're talking about, but in reality when you try what they suggest it becomes apparent that they don't know. You definitely have an intimate knowledge of the machine. your mechanical ability is sound and all your tips are possible for the average person. I congratulate you on producing the best video for someone interested in getting the most from this machine. Well done sir. I'll be working my way through the rest of your CLSP playlists.
Best Comment Ever!! Thank you for checking out my channel.
Great video,keep them coming!!!! The length was needed to cover all the good information!!
Thanks! Will do!
I have had mine only since feb .My wife and sons bought it for my Bday . after about a week of using it the thread started snapping after two cranks. Went two weeks going crazy not sure what was wrong I was doing. Finally watched one of your videos and saw exactly what was wrong . Simple thing of the screw holding the presser arm loosening it move all of about 8th inch if that. Moved it back, and I was back in business. I owe you a thanks. Also I watch your videos laughing how simple your channel is ;no flashy backgrounds . I have learned a lot about my sewing machine from you . So thank you so much.
Thank you so much for the videos. I just received my machine, which I probably wouldn't have done without seeing your instructions. Thanks again for taking the time to help others. I truly appreciate it.
Glad I could help
Your video did indeed prove worthy of watching and learning the tips you show in this video. My machine was a disaster in the way of irregularities. I had to do a lot of filing and polishing and Dremel work to it as per your recommendations in your video. After reassembling it with the step by step instructions in your video, it now works perfect and smoothly. I can't thank you enough for the handy tips.
Awesome, happy to hear your up and running smoothly.
Excellent tutorial. I appreciate not having to figure out the mechanicals. Things mechanical can always be figured out but you did the work. It's very cool that you shared it.
I am trying to get my sewing machine to stitch the way I had it when I first got it but I can't get the thread to tighten up enough when I stitch it I have the 3:00 and 12:00 with the wheel but it's still not working better but not great
Ditto
Thanks for your time and information again.
Absolutely one awesome video. Thanks Harrison.
Although I've had my machine for three years and did clean and lube it when I got it, it was not done to the extent in your video. I definitely will be taking it apart and following your instructions.
This is by far the best video ,(IMHO) on this subject. If new owners follow your instructions when getting their new machine, it would eliminate most of their problems when first using it.
god bless you i never have touched a sewing machine in my life. but today i received my chinese sewin machine and only with your tutorial i made it up and runing and sewed a lot of leather sewing.
Wonderful!
Great presentation, very helpful.
I completely disassembled my machine yesterday. I will start by deburring and grinding away all the rough areas, and polish everything. It’ll get a new paint job that isn’t green. Next, I will be installing bronze bushings in the arms (which get extensive grinding and smoothing). I also will be installing a pillow block for the cam driveshaft on the cam end, plus I’ll put in a new longer driveshaft to add a 12 “ dia. pulley. I am going to enlarge the bolt hole in the frame where the lifting arm bolt goes through, and build my own lifting arm that works on the front side of the machine, plus the lifting arm contact point will have a bearing. I’ll also be adding a 600W sewing machine motor with a two-stage pulley system.
Thank you for such a thorough and articulate breakdown of this machine. It has helped me tremendously!
Extremely helpful, cheers chap from a happy man in England 😉 great video
Glad it helped
Priceless! Thank you.
You bet!
Nice to see you finally repainted your machine, looks so much better now
You sir are a god among men. Thank you for this video. Amazingly detailed and easy to follow.
Machine is coming today. I have been binge watching your videos since last night, and feel I have a good handle on what I will need to do. Basically disassemble clean file, sand, and polish any mating parts. Modify the spool holder or build a new one. lube, time, align, and adjust! Wow Good rainy day project, but from what I see ; if I do it all well I will have a dependable machine for $100.00 and 4-6 hours labor as opposed to $600.00 and 2 hours of fine tuning on a better machine. I know the process will make trouble shooting and maintaining it much easier. Thanks for making these videos, and letting us follow your progress!
What an absolute perfect demonstration on prepping the machine to run properly. I was seeking something JUST LIKE this video. Thank you very much! I'll watch it again and begin assemble mine with the same TLC in the process!
I just got my machine running smoothly and now your video has me wanting to tear it apart. Thanks a lot. No, seriously. I'll need your video to put it back together. You've helped make this machine so much better.
No worries, I am happy I could help
Yep, made it ..
A well considered and well made video, 10/10
Hallelujah :)
I think it's the best video on that sewing machine I have watched quite a few videos on the Chinese shoe patch sewing machine and I think that is the best
Thank you
Thank you so much for your time and excellent advice. I'm very grateful for your clear advice and slow demonstration as alot of other guys tend to skip the details unlike you. I now have the confidence in maintaining the machine that I have just bought. Definitely subscribed thanks
Thanks for the support
I have no use to have one of these right now, but your machine sounds so buttery compared to the ones I've seen right out of the box. Also your method of explanation was very easy to understand.
Thank you so much for your comment
I looked through the description and comments but didn't see a link to the bearings. Thank you so much for this video. You have saved my throwing this thing to the curb.
Awesome video. I'm looking forward to pimping my machine out.
That is the most informative vid I have seen on this machine. Thanks.
Got my machine a week ago,followed your videos advice tore it apart and polished everything up. The parts that rub together in the head of the machine were very rough filed them and polished them, also all the bobbin parts and area. It sews like a charm! Thanks for all your great videos
Thank you. Your videos are a perfect answer to my prayers.
When I got my machine, it was mostly assembled except for the hand crank and wheel. After installing it and checking out everything to make sure it was in place properly I tried to crank it. It went halfway around and then it froze in place, and I couldn't crank it any farther forward, so I tried cranking it backward and the same thing happened at the same point on the machine as the forward position. So, I removed it and noticed that there were rough spots all over inside the bearing grooves. So, I decided to remove it and watch your video about how to make it run wicked smooth 3 times so I could really familiarize myself with it. The tips about polishing and smoothing out the bearing grooves on the inside of the hand crank wheel proved to be invaluable. Tomorrow I will reassemble it and let you know how it works then. Thanks for the knowledge and the great tips!
You have to write a book on these machines with all your knowledge. I would buy it in a heartbeat.
Maybe a downloadable eBook?
Thank you for making such an excellent detailed video. I've got all the tools but I don't know squat about sewing machines and timing them. Very much appreciated brother.
My friend you have blazed the trail for so many of us. May God Bless you and your family. The strokes I survived limits my work but you are a good man thank you for the inspiration and teaching! Old Mountain from Great Smoky Mountains firekeeper 👍🙏🤛
An excellent video! Very informative.
I just unpacked my machine, and your video was super helpful. I feel much more comfortable with it. Thank You!
Awe I was hoping to see you run the machine.
Really nice informative video, learned some new tricks to use.
Considering how oily these machines arrive in the box, not one moving joint or bearing had any lubricant! Just adding oil and grease where it was actually needed made my machine work smooth and quiet.
Well thank you! Detailed video on a machine I was considering buying but had doubts as to getting it to work. Thanks to your help I now have confidence to buy.
Glad you are back. It’s late at night so I’m going to watch the whole video in the morning. One of your earlier posts showed me how to set timing. It was so incredibly useful. Never would have done a single stitch if I hadn’t found you. New project is to polish and prep for smooth sewing. Thanks again.
Outstanding tutorial. You will be my reference library.
GOOD JOB BUDDY!
Thank you. Definitely the best explanation. Just bought one of these and I’m more confident now that I’m following your videos.
I watched to the end, TBH I did increase the speed. I'll go back over some parts later when I do the actual work.. clear instructions. Was not sure if I wanted to get a machine but saw some other videos on it and looked good. Saw yours and was like "Cool no problem to get this apart and back together and at least 3 hours of swearing saved from tring to figure out what's what & how to line stuff up" Thanks
Always a pleasure to watch your videos.
Thank you for your supportive comment!!
I have now watched several of your videos. I got the timing right on the machine and the needle depth correct. I put a nice thickness thread on, and now it stitches nicely. Thanks for all your help.
I made it all the way to the end! Great video, very well done! Thanks for the detail!
Just received my sewing machine from Amazon. Your detailed instruction videos inspired me to purchase the machine. Although there appears to be a lot of tweaking and setup involved in getting the machine running well, your videos make it look manageable. I look forward to “playing with my new toy” using your tutorials as a guide. Thanks.
Have fun!
One of you handy guys could start a business setting up these for those of us mechanically challenged.
Made it to the end, very complete. Thank you for taking the time to help others
AWESOME JOB. I HAVE ALOT OF WORK TO GET MINE SHIP SHAPE. THANK, GOD BLESS.
Thanks again for a well detailed how to. I've had my machine for about a year now, or I should say CASH MACHINE and your videos keep me in tune.
Excellent video. Thank you.
When setting your cams back on, use a business card pinched between the cam and the shaft block. Once tight, pull out the card and spacing should be good and consistent.
I Appreciate Your Service Sir
I appreciate that
Absolutely wonderful video, Thank you very much. Just got my machine and trying to get it to work.. Your videos are the best!
i just came back to see if anything is new. I put mine in storage back in 2019 it had timing issues.. im gonna try this again. thanks for your help..
Thanks, you have really helped me fix the problems with my machine!
Very nicely done Sir!
Thank you kindly!
Thanks for doing this. My contraption shows up today. ;)
I made it all the way to the end. Good stuff. Thank you.
Awesome video bud!
Great Video. Keep them coming.
Thanks, will do!
Thanks for the great content!
Harrison, thank you! I on week three of working on my machine … not there yet… I’ll press forward exploring every video available… thank you!
New subscriber here. I just received my new to me sewing machine!!
You're the man! All your videos convinced me to purchase one of these, and these videos have been such a huge help, THANK YOU!!!
Awesome, thanks for sharing
Greetings from Ukraine, very interesting and usful video
Thanks Sir, fine video😊
Most welcome
that was excellent!!
Thank you just got mine will look at what you have suggested.
I've been thinking about buying such a machine, and your videos seem to be a nice treasure chest on the subject. Thank you!
Highly recommend one of these. They will stitch 2 layers of 8oz leather with ease. And they are versatile. You will need to follow his videos to make it hum along as the product as delivered can be rough but once sorted out it will last forever as long as you can get needles and thread you’ll be sewing even after the zombie apocalypse. These machines are built for 100 years with periodic lubrication and cleaning.
Great video! Just waiting on my machine to arrive so it was great to hear all of this info!
Hope you enjoy it!
Absolutely brilliant treatment of the topic! That is from a retired mechanical engineer. This machine is typical of similar complexity equipment from China. That is, good basic design but needing substantial finishing work (smooth and polish moving parts) and substantial adjustment. In other words, NOT a machine for someone who does not have way above average mechanical aptitude and skills. Damn nice video!!!
watching and enjoying all your videos. I'm going to use some green corn grease, I think it's called on the parts. You helped a lot of people.
Excellent video. Thanks for sharing your experiences and knowledge. God bless!
Lee and Mary
Great video (as always). Thank you
My pleasure!
My machine keeps hanging up seemingly where the bobbin sets in wants to ride up and it hangs and absolutely will not turn just like it's stuck any help I can get with this I sure would appreciate it thank you sir
thanks, and yes I watched it all.
my man, you solved my problem! i couldnt get the bobbin thread to pull up with the top thread. i watched your other video about troubleshooting that, but my problem wasnt the bobbin shuttle lining up with the crank, its because my needle wasnt centered with the hole! it was hitting the outer edge and not making contact with the bobbin.
Glad I could help, Thanks for the support!!
I did get to the end, lots of useful information.
Thanks, really helpful!
Great video,just what I needed. My machine came a year ago and haven't set it up, a little fear on my behalf after reading the horror stories. Tired of hand sewing larger projects so this video made it seem pretty straight forward and non scary.
very interesting thank you
Thanks for the video, I learned a lot. Now the work starts on my machine. I'll give you an update later. Again Thank you !!
Wow Harrison this is an Awesome video. Long but needed for all the detail you needed to cover. Plus, the links for additional information needed to do a complete repair/recondition of the unit.
Thank you for sharing this wealth of information. I will be ordering my unit this week so i can time its arrival. Your video convinced me that it can be a great tool.
One question, you mentioned fine sandpaper to polish are we talking like 600 grit or do i need something finer ?
Great job... Dan 😊
Nice video. I enjoyed it. Thank you, Sir!
Question? What is the walking foot wants to move while the needle is down? How do I adjust that?? And thank you so much for the detailed video. Just got mine yesterday and this is the best video out of all of them.
Your cams need to be adjusted, check out my timing videos
Great video, made it to the end.
