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.
Hello. That’s a beast. You better be ready to answer some ? That’s best Unimat 3 I’ve seen on here. Like the dro to its great 👍🏻 keep them video’s rolling and stay safe.
@@proprietarysonics3723 I fitted a 3 phase 1/3 HP 3,000 rpm motor with a VFD......you can get infinite control using a 3 phase motor and VFD. To get the torque for low speed work I used a 1:3 belt reduction with speed range 0 to 1,000 rpm.
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
Looks like the outrageously expensive Bison M14x1 baby chuck. Still made in Poland but even the key and replacement jaws are silly money. Sometimes come up 2nd hand, but may need tidying up.
