- In this video I will explain what i used and what i had to do to make this upgrade work for me.
For further questions feel free to ask in the comment section.
Just bought the same setup and in the middle of fitting it. Wish i had seen this ages ago, it would have saved me some hassle. Thanks.
Great job and great video 👍
Great info. I agree with you about angular contact bearings. I fitted them to my lathe and reduced chatter. The motor upgrade looks like a great idea, I will have to learn how to do it 😁 👍.
no need to apologise , you'r english is better than my german , nice video !
Your English is fine. Great info.....
Your English is fine. Thanks for the info from BC Canada
You're doing fine brother. Keep up the good work and be safe.
Markus your English is fine, easy to understand. As far as spelling goes it is not easy, I am well educated and can't spell very well at all. I just don't understand the rules of English (American version) at all. If you don't know the English word use your native language work then add a bubble box with the English word in it when you edit your video. Nice work and nice video. I'm looking forward to more content from you.
Thank you very much for your kind words 🙂
Very nice job sir. Your English is good. Cheers mate
If you could, would you be able to to supply links and details about what you bought? It would help a lot. I’ve been looking for this kind of upgrade.
Your English is fine
Excellent video. I am considering something similar, but geared for higher speed. I'm considering either 18:28 or 18:30, would it be simpler to fit a 28 tooth pulley on the spindle side? I see you turned down the sides of the 30 tooth pullley, is this mostly to reduce the thickness, or also to reduce the diameter of the gear by removing the shoulders?
Great video, lots of info.
I’m doing the same bearings and metal gears, I’d really like your motor upgrade, this looks like the best I’ve seen so far but where did you get the motor?
New or used?
Keep it up, Thanks.
I bought it new from Ebay and it was around 130€.
If you're interested, this is the sewing machine motor I bought: www.ebay.de/itm/352901663888
but unfortunately it is no longer available.
But there are many other offers offering this motor.
You have to look for the one, where the motor is seperated from the controller because there are also units out, where the motor and the controller are built together.
Thanks, looks like I’m “adding to cart” a bunch of stuff.
Thankyou
Can the motor be used continuously for say 20 minutes without overheating? They seem very small for the power rating compared to normal induction motors.
Why did you choose such small motor pulley? What is the gear ratio from the motor to gearbox and from the gearbox to the spindle? What are max and min rpm on the chuck for L and H setting? I'm doing exactly the same mod and I just found your video. Good job.
I did choose the gearing to have the highest possible torque for threading and i don't need those high speeds either.
Min rpm for L would be 56 rpm and max 747 rpm.
For H that would be 135 rpm min and 1806 rpm max.
Motor has a 14 tooth pulley and on the lathe shaft is a 30 tooth pulley.
I have the ratios for the L and H gears on my Computer and i will reply later for them because I'm not at home at the moment.
greetings from Austria 😀
The motor is variable speed BUT top speed is 4500 RPM thus more than twice normal motor. If you want the best range you need to reduce usual ratio. I'm not sure what speed a normal existing motor has
Could you provide approximate dimensions of this motor I am thinking of using one on a lathe that is a lot smaller than yours. I have found a supplier in the UK but the information on the web site is very limited. Thanks
What size pully did you use on headstock end ? Just in the middle of the same build
The pulley on the headstock is a HTD-5M, 8mm width and 30 tooth pulley
@@markusk.488 Thank you most helpful
@@billpierce6792 No problem, you're welcome
Hey if you remove the spring that is attached on the pedal potenstiometer you can use it like a real potentiometer without pressing it with ur hands?? Does it stays in position or do you have to press it with ur hand all the time?
Yes, if you remove the spring, it stays in it's Position you put it in.
@@markusk.488 i will get tha exact same set up thanks for sharing :) lathe still cuts threads and everything right?
Did you make the pulleys for the spindle and the servo motor by yourself?? or Did you buy them?
I bought them and only had to machine the inner diameter of the bore so that they fit the shaft of the motor and on the headstock shaft.
Is this 750watt motor?
Yes, it's the 750W version.
@@markusk.488 thanks
