Chinese Leather Sewing machine Mods. 4K

Motorising, replacing bobbin winder etc....

[@shakerson]

Fantastic solution. I'm a sewing machine repair tech and am only watching videos on this topic out of interest, and this is how it's done. The other designs, even with the larger size of universal sewing machine motors, they will burn out the motors long before this thing even slows. I haven't even seen anyone running those little 1.5 Amp (or less) motors with reduction gears to drop speed to increase the low end torque and ultimately the control over the machine . Also, they will be running the motors slow, which will convert the electricity running through the foot pedal to heat and ultimately wear them out prematurely. Your setup is ideal.

[@kiyotakakaneko3602]

I was able to run it on a 30w motor with a reduction pulley. I bought a 180w motor but it was really a 30w motor. It is dangerous to trust anything made in China.

[@JamesThomas-gg6il]

A little intelligent engineering with a hammer. Best line ever

[@jtjones73]

Thank you for your video and knowledge, that is exactly what I was looking for. A little help for those wanting to motorize the machine, here in the USA (I have no idea about anywhere else, I would assume other countries actually use their exercise equipment) we can usually find treadmills that people are getting rid of either for free or very little money. Most have decent motors and speed controls, I have made many shop "tools" out of old treadmill motors.

[@Debbie4729]

Cool!I would have never thought of that idea!

[@fredprobst199]

Nicely done sir. You are quite the craftsman. I just finished putting my Chinese Patcher back together after dismantling, cleaning and doing some mods, although not to the extent that you have modified yours. My biggest hurdle was timing the machine once it was back together. That was quite the effort, but once I finally grasped the concept of the operation, it was smooth sailing. Congratulations on a job well done. I'm sure your wife will be pleased.

[@anarchytelevision8445]

Thanks for taking the time to do the video, I've had my machine for a few months now and I have found it very user-friendly and easily customizable and modifiable, I've done a few things to my machine and made a couple of videos showing what I've done on my channel, thanks again 😊👍🏻

[@boondoggleking4512]

You forgot to install a cup holder for your favorite beverage... ;) Nicely done!

[@automotivedyi1984]

Fun to mess with. I love mine and hard purchased some other industrial machines to restore. Thank you for your video. Very helpful. Cheers and thanks again from st Louis Missouri. GREAT JOB

[@alfonsoramirez3164]

Super nice set up

[@gergemall]

I have a new machine like yours and need to clean it. Thank you so much for your video 😊

[@mountainfisher4183]

Laughing I Love that, Intelligent and careful engineering with a hammer. Thanks for the tips i did just what you said and very pleased with the results. Thank You Sir.

[@jasonianfoo627]

Great delivery mate. Yours was an exception.

[@Tubefish07]

For all your efforts my good man I will now and henceforth more refer to you as “Lord Servo of Ramsbottom”! Brilliant! Cheers mates!!

[@HB-co2uq]

Crummy? Not a chance you did a way better job than some of the other mods I have seen .. us British just gave higher expectations if our selves lol ..good job mate!!!

[@HB-co2uq]

[@daverush2426]

Very well done and especially helpful , I really appreciate the way you explain everything , you've gave me good ideas on how to set up my machine.. All I have done is far is set my machine up , so now I'm looking at many videos and I was going to use a singer motor but I have a treadmill that's not being used , I am glad that I seen your video, so far you have made the best video I have seen.. Thank you..

[@tearl5676]

An excellent video, thank you for sharing this. My only complaint is I wish there was some way to note at the beginning of any video that this can be accomplished with regular house hold tools or if you need to have a lathe/foundry/milling machine etc. instead of it being in the middle of the video. Again not slighting your video, but some of us are not home machinists.

[@Centar1964]

Here is an idea to do with that machine (if I had one)...drill a small hole in the spindle on which the bobbin carrier rides...run a thread up from the bottom of the sewing arm through it (maybe some wire thread guides leading to it) and leave out the bobbin all together (but leave in the carrier) and never wind one again. Remove the bobbin winder. That's how comercial machines work.

[@tuna22lm]

For being an engineer you sure have a hard a long winded time of explaining everything. Love the job you've done though.

[@Trapezius8oblique]

Thank you, very helpful, quality work

[@joonyer3143]

Best one I've found yet. 👍

[@moonolyth]

Excellent placement for the bobbin winder mite you by chance remember what Model machine that bobbin winder came from Please. I have 2 of these machines, one came with bearings one the armatures, and both sides of the cam, but I also had to bend and tweak these arms for better placement. Regarding the sheave grove on the cam drive, if one has a grinder the grinder could be placed/clamped to the machine or held in place with a brace, while someone turns the crank and form a belt grove. Excellent information Sir.

[@gilesengineer]

Good stuff! The bobbin winder was a Singer 99/66

[@davemacgyver573]

That is what I had thought and planned to do also. I dont have access to a metal lathe, so I am going to use a die grinder, hold it very steady, while I have someone else turn the wheel to grind a slot.

[@moonolyth]

@@davemacgyver573 I would probably score a line with a cut off wheel then run a typical wheel to widen and round the groove. It should work fine withe a solid rest for the grinder.

[@funguy4900]

Looks great. Love the motor.

[@weldslikebutterfabrication483]

Add needle bearing washers, to shim for gaps, clearances, tolerances and flat file ect.. for the differences, Needle bearing washers are the cats meow - used them on my snow blower auger as they take a pounding when chopping ice chunks.

[@andrewcahill9808]

Yep, very useful, thanks from aus.

[@gingerbowman5399]

Great video! Love it if you did a video on how you mounted the bobbin winder in it entirety ?

[@andrewelliott4217]

Hi, great video! I bought the singer 99/66 bobbin winder but the bobbin pin is too large on diameter for the patcher bobbins. Did you modify this to make it fit? Thank you

[@MrMcbuck48]

Very good information. Thank you,

[@davegaziano6619]

I enjoyed your video I have a question about the bobbin winder I was looking foe them on amazon but they have so many of them can you tell me the model number you got. Thank you

[@ItAintMeBabe99]

Good job ! Where did the motor come from ? What was it used for previously ?

[@fordfan3179]

If you could buy any AC motor you like for that machine, what would you get? How would you set it up?

[@gilesengineer]

The bobbin winder was a Singer 99/66 Hope that helps!

[@bushratbeachbum]

It would be helpful to many if you added information regarding the rectifier and controller. Interesting video, im about to undertake a similar project but first need to grab a vfd for my hercus 9 lathe

[@fordfan3179]

Elegant! How's it holding up? Still works ok?

[@howardmandel7930]

Treadmills?

[@charlesmalloy8150]

I can't even get the top thread to feed without breaking, loosened the 2 tensioner and still won't work. ANY HELP WOULD BE AWSOME.

[@grantlapointe9152]

Good-day Sir. I have thoroughly enjoyed your video as a machinist and heavy duty mechanic. I have been thinking of purchasing one of these after watching many other video's although after watching your video I now know I will. I have also subscribed to your channel. Please feel free to contact myself if I can be of assistance to your self.

[@mohammedzeco8006]

Fantastic!

[@trevorcmorris]

....often referred to as "Morris" technology....as in " don't use force....get a bigger hammer"...

[@antsalt8409]

cant you see the foot being battered running it with the foot up, we can all retell what he did and the book said, keep reading not advising

[@yhonie714]

Can you list the electronics you've added to the machine. Or put a link to where i can find them

[@cristobalmartinezflores7261]

Hola gracias por su video. Podría explicar como ha realizado para poner el regulador de velocidad.

[@legendarycustomleathers8387]

Swap the washers.. Always have washers when 2 metals meet

[@jenniferoliverosgomez3613]

Hello, would you tell me if I can get the machine in Amazon? I wanna know the price and if I can Buy it...thank you!!! Greetings from Colombia...

[@IzziedeD]

Jennifer Oliveros Gómez yes, there are many brands on Amazon, almost all the same, for around $90-120 USD.

[@1duskyknight]

Jennifer Oliveros Gómez: Hello Jennifer, If you have access to Ebay, you can get one for about £67 british pounds,. sorry i'm not sure how much it is in your currency.

[@hughanderson7285]

What’s the proper name for this?

[@MasterofCrude]

Nice Vid !!! Do You know part number of OR model number of machine "Bobbin Winder" was used on. ThanX

[@gilesengineer]

It was 99/66 type

[@MasterofCrude]

@@gilesengineer ThanX

[@douglaschell1132]

My Chinese Leather Sewing Machine is like that . i put my on facebook.

[@antsalt8409]

careful and intelligent would be marking where it needs bending then taking it off and bending to shape, on a machine like these you was pure lucky the cast did not break, chip or crack, not a good idea at all

[@gilesengineer]

I agree in an ideal world I absolutely agree that it would be much better to take the arms off to adjust them - however, I was unable to (I can't remember why.... It was some time ago). Having spent many years working with a variety if materials - including cast iron - I was of course suitably cautious, allowing for the the inevitable poorer quality.
