I’ve been keeping an eye out on eBay, so many makes out there. I’m hoping to not buy wrong thing 

A lathe on a Borel stand with a countershaft and a sewing machine motor is the best setup. And make your belt out of boot leather for no noise. Here is one of my many videos.

There are many options, from single speed motors with countershaft to give a limited range of speeds, to variable speed AC/DC motors with or without countershaft, usually with a foot pedal rheostat to vary the speed, to more modern DC motors with variable speed, often with a knob to set the speed but could be with foot pedal or knob and foot pedal for on/off.

 

In my early days most lathes I encountered in the U.S. had the AC/DC "universal motor", mounted on the famous Borel base,with foot pedal, which is familiar to most watchmakers, and which I despise (haha). I hate not having a fixed speed, and those motors hate being run slowly- no torque- so a countershaft is really necessary in my opinion to step down the speed from a fast spinning motor.

 

DC with a proper control will give a very wide range of speed with plenty of torque at slow speeds. There are usually some DC motors with controler ready to mount up for sale on German Ebay, a friend got one and it is very nice. These tend to run very smoothly, and as stated, have plenty of power over their range, are quiet, and eliminate the need for a countershaft. Aside from the mentioned one that's offered as "for watch lathe", there are many industrial sewing machine motors available on Ebay, often marked as servo motor. A servo is just a DC motor that has a precision control. These tend to be overkill in size for a watch lathe, but there are smaller ones, and they tend to come complete with control. That would be far, far, better than the motor on your mother's sewing machine, which is usually a lower rpm "universal" motor, controlled by rheostat.

 

As for belting, that's a matter of choice. There are many options, from miniature V belt, to leather (which is fine), to fusible plastic/rubber belt, which is the choice of most folks I know, myself, and industry. If you have an industrial belting supplier in your town or nearby, they likely carry Habasit belting, which comes in a number of varieties of flat and round shapes. The round stuff is called Polycord and is very good. 4mm would be perfect. It's fused by cutting it to length cleanly, then put a piece of 1 or 2mm sheet brass (or steel) in a vice, and heat with a torch until hot enough to melt the belt. Press the ends on opposing sides of the hot metal, face to face, let melt, and slowly slide it off so the ends meet up. Hold until cool, then trim off the bead around the joint. I have belts joined like this that have been in use for a decade, zero issues.

 

In the pics you can see my primary lathe, the Leinen, with a 380v industrial 3 phase motor, with built in countershaft. That lathe had a motor integral to the base when bought, which was switched to a DC with control in the base, and finally I liked the industrial motor so much I pulled out all the DC stuff and have been running it this way for almost 20 years. The other lathe is a Favorite that my workshop mates use, it has a single speed (1400 rpm) motor, no countershaft, but 4 options on the pulleys, and they are very happy with it. The pic of the motor and controller is the one a friend bought off German Ebay (sells internationally). From the screwdriver stand you can get an idea of the size. Nice looking stuff, was under 200 bucks as I recall.

I’ve been looking at this motor, it’s just motor though.
