Scam Alert. Members are reminded to NOT send money to buy anything. Don't buy things remote and have it shipped - go get it yourself, pay in person, and take your equipment with you. Scammers have burned people on this forum. Urgency, secrecy, excuses, selling for friend, newish members, FUD, are RED FLAGS. A video conference call is not adequate assurance. Face to face interactions are required. Please report suspicions to the forum admins. Stay Safe - anyone can get scammed.

Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!
Possible candidate for 3-phase for my lathe?

Yeah, I need to be able to do the Abom79 .25" DoC every so often
In delrin mind you so there's that
I'll keep saving my pennies

Not a bad deal for a 1hp motor and VFD. Buy it if you've got the cash, and a project in mind for it, but I wouldn't buy it to swap for a lathe with a 1.5 hp currently. Might be nice on a drill press or something though. Or build another grinder.....
I would love something like that for my Myford eventually.

Ah, a Baldor VFD. Maybe that's worth something. But right now, a CE (hahahah) 2.2 KW VFD is about $115, new. So the whole package would look like a deal at $125-150. But the Baldor VFD might change that.
That's a Baldor Vector drive motor. It's specifically designed for VFD applications. It has a max RPM of 6000! New, they sell for over $1,000.00.
Ya, buy the motor for another project.
As @thestelster says, that motor is VFD rated. Setting aside that amazing top speed, it probably has a very low bottom speed too - maybe even zero rpm at full torque.
Ya, buy it.

maybe 1hp is ok if your belt / drive situation is not perfect - I cut my teeth on a Tida branded lathe that looks just like your busy bee and that thing would slip the belt at any opportunity so motor power was more or less irrelevant...
do you find that you bog the motor on your machine or slip the belts first?

I've never had the belts slip except for when I put it back gear but don't release the bull gear
Holy jumpin!
The motor is listed on the e-motors direct site for $3273 :O

General Information
Overview The Baldor Series 18H PWM control uses flux vector technology. Flux vector technology (sometimes referred to as Field Oriented Control) is a closed loop control scheme using
an algorithm to adjust the frequency and phase of voltage and current applied to a three phase induction motor. The vector control separates the motor current into it’s flux and torque producing components. These components are independently adjusted and vectorially added to maintain a 90 degree relationship between them. This produces maximum torque from base speed down to and including zero speed. Above base speed, the flux component is reduced for constant horsepower operation. In addition to the current, the electrical frequency must also be controlled. The frequency of the voltage applied to the motor is calculated from the slip frequency and the mechanical speed of the rotor. This provides instantaneous adjustment of the voltage and current phasing in response to speed and position feedback from an encoder mounted to the motors’ shaft.
