Rockwell/Delta belt/disc grinder

Yes, but you might need to bypass the overload heaters as single phase motors tend to draw more current than 3P for a given horsepower. BTW, I have the same sander and it needs a boatload of power to sand wide boards---don't skimp on the motor size.

I have a 1.5 hp.
I bought this machine about 8 years ago. I paid $350. I put it on CL and it sold for $500 in a few hours. I would have kept it, but it sis not have the 12 inch disc.
I bought this much nicer condition unit, with the 12 inch disc, for $600 including a single phase 1.5hp.
I may touch up a piece of wood from time to time, but my main interest is metal fab.
thanks for the advice.

If you wire the input mains to L1, L2
wire a jumper from T2 to L3
wire the motor to L1, L3
Then you don't have to worry about the overload heaters unless they are sized wrong but its not going to trip for phase loss. Each heater is experiencing the same current, the fact that the (2) and (3) heaters are experiencing the exact same current is not a thing as the single phase motor won't run in a phase-loss condition.

I am being encouraged to buy a phase converter.
I will try the PC first then move to option two.

Yesterday, I did an hour of due diligence for a best price for an American Rotary phase Converter. AMAZON had the price and the product. I ordered a 10HP CUL Listed American Rotary Phase Converter 10HP 1 to 3 Phase CR10-CUL … It shipped from Toronto yesterday.
I am watching for a Kearney and Trekker milling machine.

My son and I replaced the black bottom skirt with a flat steel plate and four casters. Two of the casters are locking.
The bottom space will be a good for belt storage.
The Delta grinder moves easily, now.
My ordered American Rotary phase converter should be here on Monday.

The knock on the door and the delivery I was waiting for just happened, three minutes ago. The American Rotary phase converter I ordered arrived. The next pleasant surprise was, THE PACKAGE WAS NOT DAMAGED. The deliver driver may have not seen the 5 FRAGILE tags and missed his opportunity to take up the challenge of how much abuse can this package take.

I have to be careful with how I answer your curiosity question.
I do not know enough about phase conversion, so, I had to rely on experienced persons I know and trust to help me make the right choice for my situation. My understanding of my situation was this. I would not have any concerns with an AR RPC. There were circumstances where a VFD may not be my best choice.
Almost anything I can say, at this point, will give persons cause to dissagree because of their experience or beliefs.
My due diligence made my choice easy. I cannot discuss anything where a persons beliefs are involved. Belief makes it personal.
The choice I made certainly was not the least expensive, by a wide margin.
After I placed my order an American Rotary representative called me on my cell. He wanted to know if I had done my "homework" and he asked a bunch of questions. In a few minutes he was satisfied with my choice. I offered to move up a $1000 to a expensive and more powerful model. I was told this would not be necessary.
AR set up an account with my name on it, so if I have any questions the base information will be there.
I am totally confident with my choice. The American Rotary is 100% MADE IN USA. The unit I bought came from a Canadian American Rotary retailer, in Canada. There is a Canadian Maple Leaf on the Canadian model and a Canadian UL approved sticker on the side.
I always look for made in USA or Canada, first. I have never been to that store that sells nothing made in North America.
I am too old to start a business of my own, so, the minimum I can do is to support a locally made industry.

Thanks.
I appreciate the convenience of the rotary converter, especially if multiple 3 phase machines are involved. The VFD would have provided variable speed control, as well as soft start and dynamic braking (which is a good safety feature). Both are great options. And congrats on supporting USA industries.

At first I thought this was it. Another look at the shipping label suggests this box is 2 of 2. So, where is 1 of 2?
A quick call to the courier customer service put a trace on the lost package. It had been delayed in Calgary, recovered and sent on to The West Coast. When 1 of 2 arrived at the terminal, it was put out on a delivery truck for another area. An on-the-road transfer to the right truck the drlivery was complete.
The first box weighs 20.9 pounds. The better late than never second box weighs 219 pounds. I will need some help with that one.
The second box contains, what is called "the idler". The idler is a Made in USA BALDOR procuct.

I have decided to mount my American Rotary phase converter to as repurposed pressure washer cart. The cart will be powered from a 25 foot heavy cord I have been using as an extension for my welders. The cart will have a plug-in for a 220V single phase for the welders and other plug-ins for three phase power.
The original hose hanger, after some minor modifications, will become a cord hanger.
I have not put as much time into this project as I would have liked. Life got in the way.

I have had other distractions and I have not done anything with the rotary phase converter and cart. Soon, is all I have to add.
