Thank you so much for stopping by and I will see y’all on the next video!!
Let me tell you. Harrison is The Man ! He fixed my tension problem and other issues in a quick and easy video call. He talked me through every step of the way and got my machine up and running in No Time ! Very easy to deal with and very knowledgable. It was so worth the call ! I Highly recommend him for any issues with this machine. He really knows his stuff ! Thanks man for all your help ! I truly appreciate it !
Harrison, I bought one of these machines a few months ago. It worked well right out of the box. Then I changed to a heavier thread/needle combo , and all hell broke loose! It was just one problem after the other. Thanks to you, and your numerous videos, I was able to fix each of the problems as they came up. You are my Chinese Sewing Machine Sensei!! Thank you so much!!
No worries, thank you for commenting
my machine works backwords i can not get the timing right waking foot works in the wrong way
@@waynekneese2162 Check your rear cam (farthest out from the machine)....it should be pointing away from the machine when you set the timing (to the rear)....
I swear, every time I’ve got an issue with my sewing machine I find one of your videos and immediately solve the problem. Thanks a ton!
You are so welcome!
I don't know who is making this contraption but they for sure owe you a commission. Without your channel I would have junked mine. Thanks
I wish I could give you 2 thumbs up. You solved my issue. The bobbin timing was off. Keep up the good work and thankyou.
@15:00 - it's not that engagement you're mentioning, it's the needle rod hitting the top of the presser foot (since the presser foot is lifted). I just got mine and have been having fun cranking it slowly and watching how everything works.
Thank you very much for putting these together. I just got done tearing mine completely apart for a deep clean and reassembly was helpful thanks to you.
Dude. Correct 100%
Finger tested for needle depth; set cam wheel to 12, reset bobbin & holder to 3 = everything started working properly.
Thanks man.
So, after looking at these machines for a while, (over a year) and after hours of research, i decided to go to youtube. Lots of people and lots of videos. Well, my machine arrived today. I took a lot of stuff off to clean, polish and lubricate. (I'll strip and paint her proper when I can get back outside). Got my bobbin wound and thread threaded, grabbed a hunk of scrap leather, cranked the handle and no bobbin thread. Back to your videos. Nobody else is as thorough as you. Anyway, bobbin carriage was off by 1 tooth. 12 and 2 got it close but the needle refused to pick up the bobbin thread. Finally pulled the bobbin out of the shuttle and just started spinning the handle and watching. Soon I decided that the carriage didn't advance far enough for the shuttle to catch the needle thread. Back to 12 and 2. The carriage was so close to the 3 o'clock that I was getting ready to disassemble the whole thing. Watched another Hightower tutorial, moved the carriage....again and finally stitched some leather. Still need to adjust the thread tension though. Top stitches are a little loose but I recall seeing you explain all that so tomorrow I'll watch that video again and hopefully be creating lots of wonderful leather goods! Thank you. If not for your videos and encouraging words I'd likely be the proud owner of a new anchor. Keep on doing what you're doing my friend and God bless you! Best regards and Happy New Year!
Thank you for your help. None of the timing was even close to correct on my machine. Your voice instructions did not actually fix the timing. However, after matching my cams to the images of your machine in the video, it works perfectly.
For the spool fix, I switched the thread post to a tall threaded rod and cut rounds of flexible packing foam to stick up the middle of the spool to get the proper spool tension.
The final problem of snapping threads was caused by the needle not going low enough. Also, upgrading to a Big Spade Foot needle to match my #38 thread probably helped.
I can't tell you how grateful I am for your excellent advice, and especially your video.
I should mention that prior to this I had spent considerable time smoothing, sanding and polishing various parts to make it more reliable. For all the bobbin area parts I used Birchwood Casey SUPER BLUE LIQUID GUN BLUE, and soaked in oil to prevent the parts from rusting after getting down to shiny bare steel.
I now have a reliable machine. (after failing at least 2 dozen times to get it right).
Thank you so much for your comment and advise!!
Thank you for this video and time you spent explaining!
Great information. I got my machine two days ago. After building a stand, I completely disassembled it. I painted it and polished all the moving parts and contact surfaces. Some grease, oil, a few washers, and a little tweaking of the arms and she is smooth as butter. I'm pretty mechanically minded but your videos helped me understand the interaction if all the parts. I'm waiting on needles and thread but am confident it will sew like a champ when I'm done.
Thank you very much for this precious video. Now, my chinese machine is perfectly working.
I will have a look on another one to be able to set with a heavier needle and thread: I sew a 6 to 8 oz veg tan leather and I need to set my machine for this kind of job.
Thanks again and go on doing more videos like that.
If it wasn't for your video I wouldn't have got my machine to work, thank you!
You are very welcome
After watching your videos three times, I finally got my machine to so thank you very much.!
Awesome info. I just picked one of these up after hand stitching for years. I tried to rope my Mother into helping me, she's been sewing for 50 years with machines. Turns out she doesn't know much about how the machines actually work, though 🤣. Had to Turn to the interwebs and found your channel. Helped a ton.
I've watched your videos over and over, paused and checked, adjusted, tried, reviewed, paused, adjusted and so forth. Today, I managed to make my machine stitch for the first time without breaking the upper thread. The machine I got was off in just about every place it could be. I'd played with the bobbin timing for hours, and finally decided that the presser foot cams must be the issue as you included them in this video. I made a change there putting the cams where you show and it worked right. I still need to fine tune the thread tension, but it's pretty close as is. Thank you for taking the time and patience to answer our questions!!
Awesome, I happy I could help
Omg, thank you! I recently got the heavy duty version and even though it seams I threaded it correctly, the thread kept snapping. Drove me nuts. I'll try this setting and see if it'll do. Thanks!
You helped me so much, this machine would be useless without the hard work you put in troubleshooting and uploading these videos.
Glad I could help
Thank you. Thank you and thank you for your posts on these machines ✌️
Glad you like them!
Thank you so very much. I would have been lost without your videos (this one in particular). I am forever in your debt. Thank you again.
You are so welcome!
Just moments ago I watched your video on this machine made 4 years ago and stated I was curious if it was still working. Think I'll order one for myself tomorrow because you being so informative. That gives me fath in you and what you say.
Oh yeah, it's still working
Lowering the needle worked for me. Thank you for all of your videos. Very helpful.
Harrison I can't thank you enough. I was getting ready to throw this machine out, but I watched a couple of your videos and it works fine now. I subscribed because I want to keep up with your info. Hope this message finds you and your family happy and well.
You are very welcome, thank you for the views and sub.
Thank you so much. I had given up on my patcher until I saw this video about how to check and adjust the timing. After a few adjustments of the cams and bar I am back in business. Thank you again.
Glad it helped
I've never stitched anything in my life yet I randomly came across these machines on youtube and now I really want to buy one, use my machinist knowledge and tools to make many improvements and either put it to work making things just for fun or sell it onto someone who'd benefit from it! Thanks for sharing.
There's a market for that kind of work on these machines.
@@MainelyAcresFarmBrooks I think I'll be buying one soon to upgrade and sell on. Cheap enough for a bit of fun.
Thank you Harrison for purring this video out there. I dropped my machine soon after unboxing it. It threw the cams all out of wack but after watching your video, 3 times ;), I was able to get everything up and in working order.
Flip the needle y’all, I checked my timing and whatever he’s showing here. I read the comments they said to flip the needle, the flat part of the needle is touching the base now and it worked perfectly. Just flip your needle.
Thanks! I’ve been looking for a video that explained this exact thing for weeks. This was perfect for me to finally get my machine running correctly.
Awesome, I am glad I was able to help out. Thanks for the super and have a wonderful holiday season.
Thanks man! now if i can get my back stich as nice as the top we'll be golden. It is working now though.
You can do it!
@@MainelyAcresFarmBrooks i did! Thanks
Thanks for this picture of the bobbin shuttle, I fought the timing on my machine for almost an hour lol.
A summary of my woes, cured:: FINALLY got my stitcher to sew a row, after a week+ of looking around, watching ALL videos available.
I finally realized my cams were almost 90° OFF (timed *early) after watching *this video 3-4 times.
Hunh? Am I *that stupid? Evidently. [My rockers might have gotten bent in transit]
WHAT I HAD MISSED was that the FOOT HAS TO BE UP to find the appropriate resistance with Crank @2:15.
Get the Crank there, position cams as shown, (WhereEVER they are now). Get the cams correct BEFORE any other modifications...
yeah like he says.
My thread channel [above the needle clamp from the needle driving tube] was VERY sharp and needed a hone and rotary buffing to eliminate cutting the upper thread!
BTW, any thread feeders MUST direct the thread to leave the top of the spool or thread WILL jam if off the bottom.
Bobbin edges, bobbin cases, and bobbin drivers must be honed; I used a Dremel buffing fiber wheel that comes impregnated with polishing compound. Also useful: Dremel wire wheels in a drill, a triangular machinists’ hand burr remover.
Also, I used cold gun-blueing on the needle driving tube (turns steel black), so I could visualize wear.
Do not over-lube, or it’ll come out onto your leather(!) Avoid red sticky grease, use bicycle lubes. Mo,later.
Good Luck.
Thank you so much for sharing you experience with all of us!!
thank you sooo much for these videos!!! this one and the needle height video got my machine running! your videos have done a lot for this niche community
Glad I could help!
Harrison you don’t have any idea how much you have helped so many of us.THANK YOU.
I’m still waiting for mine to be delivered . Thank you Harrison .
Excellent video thanks very much! You might want to retitle it to this is the second video in this series you should watch. Thanks again.
Thanks for the tip
You explain things sew well
You make the best videos on operating this machine, and thanks to you I'm having a ball with mine. I've sewn everything with it. Thanks again.
Glad to help
Love the pipe screen laying behind the machine.
It's simpler for me to adjust the timing on a small block chevy than this, but this is very informative and should get the job done. Thanks...😊
LOL, Thanks for watching! 😂
I got some good stuff from this, but you put the first order of timing business at the end.
Thanks for the video. I used my machine after a break and timings were quite a bit off. Now it works fine 😊
Had this machine for a while but it started shearing again. Your vid solved it! You're a legend!
Glad I could help!
Thank you very much, just brought a cobbler sewing machine, was sewing nicely then started playing up. This has helped greatly
Love your patient, methodical approach
Thanks so much, you are saving us time, thread, curse words and needles
I am happy I could help
Hi Harrison,
Thanks to your tips, I finally got my machine working!
My thread kept snapping. Adjusting the depth of the needle with my finger underneath did the trick.
Thanks for your help! After a few days of tinkering with my new machine it runs like a charm! Good advice
holy crao you saved me again! you are the man! Thank you sooooo so much. I would have just thrown my machine away by now if not for you
Glad I could help!
Super helpful. I just did the needle conversion and am now deburring and fine tuning
Want to thank you for these tips. Have been fighting my machine and giving up on a regular basis. I have a Willys Wagon I've been meaning to do some minor leather work on, say the armrests, perhaps a sunvisor or two. But until I did all the modifications tonight that you had suggested I have had no success with my machine. Tonight my test piece went almost perfectly so now I will put the machine away and wait until the day that I need to work on the armrests, but knowing that it will be working out. Really appreciate the fact that you addressed all my problems. My UA-cam channel is Three Willys for Jeremy Wilson.
Great info. I am setting mine up tomorrow! Thank you so much.
Good luck!
Thread snapping/fraying can also be caused by a damaged needle. I was a professional costumer for many years, and in my experience incorrect tension and damaged needles (burrs or dullness) are the most common causes, so if you have already sewn a few inches on that piece of leather, and your stitches looked balanced on both sides, then I would recommend changing the needle before you do anything else. It’s simple, needles are cheap, and you will save yourself a lot of time/aggravation.
Hey thx man. Ur vids really did the job. Mine is running fine. I just got it friday too lol.
God bless you for making these vids ! helped me out big time.
Thanks and many blessings to you as well.
TY for doing such a good job, havnt fooled with my machine in a while, went downstairs and made one or two small adjustments and now its sewing. still making minor adjustments to get my stitches just right but its working.
My machine should be arriving in the next few days, and I'm certain you've helped me already!
Great to hear!
Hey there Harrison. I'm glad you posted these videos because they gave me a place to start from once I got my own machine. Mine seemed to come extra special messed up, complete with a slightly bent drive shaft, snapped off needles in the pitman arm, and a bent presser foot arm.
It's been a few months now of tinkering and not being able to get it to run without snapping thread. This video finally put me over the hump. After adjusting, sanding, and polishing just about everything on this machine, the last thing needed was shifting the cams so the presser foot was advancing while the needle was out of the leather. That took a deadblow hammer and cold chisel though because the cams seemed to be glued to the shaft at first even with the set screws completely removed.
Now though it finally works! Thank you so much for posting these videos!
Thank you so much for this video. Saved me a whole lot of aggravation. Nothing on this machine was right when I bought it. After going through this video step by step pausing to get things set. I was finally able to get this thing to work.
Great to hear!
You sir are a sewing genius.
I have been fighting my machine since I received it. Watched this video thru and then started with the alignment on the back side and then the bobbin.
Thank you sir.
Glad I could help
I want to thank you for sharing this video with us on how to set up the timing on the Chinese Leather Patching machine, without it I would have sent my machine back. I could never get mine to work and had just about given up until this video allowed me to get the machine to make a good stich. I could not see online any really good video's about the timing issues until I found your video and I wanted to reach out to you and thank you personally. I have also watched a few of your other video's and found additional information that I found very useful such as the video on properly lubricating the machine as well as other things. Have a great day and keep up the great work in getting useful information in an easy to understand method out, because it really helps.
Thank you so much for that heartfelt comment!! Means so much to us!!
Wow!!!! You are the man !!! I've had my machine 3yrs now (two of them) and just found out the timing is set way off, set up at the factory (Although they still work). Just reset cams then the bobbin etc. The stops at 12 and 2 make more sense to where the needle and foot rest between movements. and I think it is working much better really great !! Thanks a bunch!
No worries, I am happy I could help.
Thank you for talking about the cams 🙏🙏🙏
I was so frustrated and about to send my machine back! I had no idea the nut on my wheel was loose and the whole thing was off timing. Thanks so much!
Glad I could help!
Worked for a day. Now my top thread is snapping... I’ve done everything 😑 this machine is going to be the death of me!
It’s strange, it works great with no material under the needle, then as soon as I place a test piece, the needle re-pierces the top thread making a knot? So weird.
thank you very much for your time an clear explanations.
Glad it was helpful!
Thank you very much! I was having an issue with thread breakage and needle binding with the presser foot. Watched your videos and the machine now runs like a champ. Thank you again
Glad it helped!
You saved my life with this. This is THE video. I watched all of yours ....been tinkering and trying for 3 weeks but couldn't even pick up the bobbin thread. The more I tried the worse it got. With this vid, the machine started to sew in under 10 mins. Omg. Interestingly my 2nd cam, the one with the rolling element, seems fixed on my machine...? It has the thread and screw, but I could not get it to move even with a hammer (carefully). However, it was quite in the right position as soon as I set up the first one, closer to the machine, according to your instructions, so I did not try too hard. It looks exactly like your setup - your screws are not centered exactly 100% either as far as I can see. And it works, so, whew.
Thank you very very much, most sincerely. I had all but given up hope.
I happy to hear you are up and running. The cam might just be stuck, it shouldn't be permanently attached to the drive shaft.
Thanks very much for sharing your knowledge of these machines: I didn't know how to sew, but had some leather bike stuff that needed new zips and other repairs. After watching many of your videos, I got a machine and 2 days later; my leather repairs are complete! I was expecting a difficult bodge and many problems but it all went very smoothly, thanks to your preparation given on needles, threads, bobbins, tensions, common failures and how to set the sewing machine up. My results look as if they were done professionally - I'm so pleased! I'm now looking for other things to sew... Thanks again for sharing your skills. All the best!
Thank you for your comment!!!
Awesome video! Received Cobblers machine today. Still had a piece of leather under the foot. Stitching was good. Threaded and test sewed a piece of my own leather. Timing was WAY off!! The foot was walking the material while the needle was still in the material. I was worried that I would not be able to figure it out. This video helped immensely and after setting the pitman rod and cams, I was up and running in minutes. Thank you for the video! I’m very happy :-)
Thanks for commenting and I happy to hear your up and running.
Thanks, your videos have proved very helpful.
I appreciate it all!
Great tip about the big spools up on top and tension.
After the video I got a bit of foam pipe insulation and electrical tape and was able to make that post about 1" diameter to better hold the big spools. Not as elegant as your solution but probably quicker.
Thanks for sharing
Thank you very much for the informative video. after carefully following it i was able to resucitate my DOA machine after dusting it off the shelf!
First of all, please allow me to say THANK YOU!! for such good videos. I've learned lots from them. Your channel is by far the most recommended source of info for the CLSP machine. Now I've got a question for you about this video on timing the machine: Looking at 9:36 point in the video you talk about checking the pittman rod, with the handcrank just past the 2 O'Clock position. At this point the needle is down, and the cam on back is just starting to move the rod that causes the foot to "walk". How can the foot walk with the needle down? I'm sure I'm missing something, but with my machine timed in that manner it just won't sew. If I set the cam timing so the cam hits the arm allowing the foot to walk while the needle is up, it sews ok. I'm looking for guidance here, what am I missing?
Harrison, thank you for your videos. They have helped understand a lot about these machines. I had been using my machine without any issues for a while and then I started having problems with it (i.e., snapping thread, breaking needles, and jamming among others). I oiled it, replaced several needles, followed the instructions on resetting the cams, pitman arm, and needle depth. After several hours of micro adjustments, it was able to sew. However, sometimes it jams and won't allow for a full rotation on the crank wheel. It stops around 7-8 o'clock and acts like it is stuck. I have to raise the foot and work the crank back and forth to get it to finish the rotation. I'm using the bigger 140/22 needle, which works, until it doesn't. I'm also using strong thread, but not too thick...T70 maybe. Any suggestions would be helpful, and thanks in advance. Blessings.
I seriously love your videos on this machine. You're amazing!
Thanks from western Colorado!
Life changing!! lol I missed one of the guides when threading. Thanks sooo much!! 🙏🏻🙏🏻
Many thanks man, it helped me to get my new machine working. 👍
Thanks for the videos on this machine. The instructions that came with my machine were definitely lacking and hard to understand. These videos help a lot!
Harrison, I was watching some guy sowing leather and at the end he gave you a shoutout. I was thinking about making saddle bags as a hobby and looked up some videos. I then remembered that you are into sowing leather. John
You should do it!! If you need any help, send me a message on Facebook. How's the family doing?
Clearly my machine was way off. I still have to go to fishing line on the top thread. Every grade of thread I can get my hands on breaks. I'll try to adjust the needle as soon as I can. The needle holder already pushes the foot down though. It's almost 4am. My patcher is made a little different than yours. I do not like one of the differences. I'll catch you later. Thanks for the info. It is helpful. -Ron
Just a tip. Your camera is auto focusing on the box of buttons on the table instead of on the bobin as a result of the box being larger and brighter. To fix this don't leave the box there and shine a light on the bobin. I love your videos. Very insightful and useful to get to know the workings of these sewing machines..
Thank you for those tips, I am always improving how I shoot videos
Great video. Have been fighting the timing for hours!! Have a great day 😀
Thanks, you too!
Thank you so much for your helpful videos!
You are so welcome!
Super helpful! Thanks!
Glad it was helpful!
Thanks for the this video --fixed my cam problem!!!
Great to hear!
Thank you this is a great full description, and explanation. Just what I was looking for .
Thanks for the advise
Any time!
After many frustrating attempts to catch the bobbin thread with the center of carrier at 3 o'clock like you said, mine finally caught the thread and sewed well centered at 5 o'clock? Is there an explanation of that? Should I just leave it alone and continue or make another adjustment?
Very good videos and glad mine is sewing now.
If it's sewing good I would leave it alone. The reason it's different on your is due to the pittman rod timing.
Tanks for your help
Been waiting on a video!!!🔥🔥🔥🔥
Thank you👍
Awesome video great help exactly what I needed help with you the man
Awesome video thanks
Glad you enjoyed it
Meet sweet petite
Right to the point 👍
Its alive
..thank you
Good to hear
i really enjoy your videos , you have been a great help. i sewed 3 patches on my vest it worked fine, then i came back a few weeks later to sew more patches on my vest , now it keeps bunching the patches up, i loosed the foot but its just bunching up my patches and not sewing anything. but seems to be working fine. and it is also bunching up thread on the needle. am i missing something ? thank so much for any help.
Excellent explanation! Thank you!
Glad it was helpful!
I found a circular needle works great for pulling the thread through the holes in the bobbin.
I appreciate the information. Many thanks good sir.
Hi Harrison, I was watching this video because of a similar issue and I noticed a small detail on your machine and mine. As you were threading yours I noticed that your second
tension wheel is on the bird whereas mine is on the machine body. Would that matter any? I have also noticed on my machine when I sew a few stitches my thread spool starts to loosen its tension and then the thread snaps. I think you have covered all that you can on this constant issue. Thanks for all your videos. I have to keep working on the timing to smooth things out. I will make it work.
The placement of the tension disk doesn't make much of a difference, that's just the way my machine came. Is it your upper thread or bottom thread that keeps snapping?
That slipknot hat is awesome! I’ve watched a video or two but after that I had to definitely hit the sub button.
Awesome! Thank you for the Sub!
Appreciate the video
