very satisfying sound, smooth. The DC motor is quiet and smooth running. I have the original motor on mine and it hums and periodically the sound goes up and down. Must be the bearings so will change those out. Want to keep the original as long as I can. But I must say changing the speed on a fly with VFD is neat, I dont much like changing them O ring belts but its not too bad. Great little true running machine.
@gyrogearloose1345 Жыл бұрын
Interesting to see what you have done. Thanks for sharing. One thing comes to mind: With the larger pulley on the motor you've got tremendous speed for the spindle but lacking torque. Better to go the other way, Belt reduction to spindle - More torque delivered to work, less droop under load, less motor heating.

I'm considering buying this lathe used as I'm interested in machining. Does anyone know if this lathe would be a good lathe to learn on? I'm 22 and a student so the cheap price would make it really convenient. And then i could swap the motor down the road. Great video👍
@proprietarysonics3723 Жыл бұрын
Yes I bought this when I was a student and it was very helpful. You can cut up to 50mm diameter in soft metal/plastics. The best point for me is the compact size, it can be moved by hand unlike other lathes. That being said, these machines are quite expensive now. I believe I would rather go for a larger, older lathe you could find locally on Facebook or something similar. You will get a much more capable machine for a few hundred £. When I bought this Emco they were reasonably priced still. You could get a Myford/boxford or similar for what they cost now. Regardless, having a lathe will really help you improve skills as a student, as it did with me a few years back

Nice chuck - seems much larger than the standard emco one? I have the same machine but I haven't got round to using it yet - the old motor is pretty worn and am considering a brushless upgrade. Where did you get the indexer from, if you don't mind me asking? Nice one on the pulleys as well - when mine give out I'll know who to turn to :P
@proprietarysonics37233 жыл бұрын
The chuck came with a few extras when I bought the lathe. I tend to use this keyed one more oftern than the thin chuck. It is made by emco. I spent sometime looking at brushless motors but the options for RPM and speed control are not are desirable at a large DC motor from my research. Check out my other videos to see the motor setup details. The Indexer is a cheap 75mm table from India, about £60 new. Thanks

@proprietarysonics37233 жыл бұрын
The autofeed attachment is very clever, but the ratio between the spindle and screw is quite high and unadjustable, so I always found the feed to be too fast. I have been thinking about making an autofeed system by having a small motor behind the lathe and a belt running to a pulley that fits right over the feed handle. It would need some kind of clutch though I suppose
