Harrison M300 Lathe

I only have one mill and one lathe. Since the mill already had variable speed I used a rotary for that. Thought it would be helpful to have variable speed for the lathe too so used a vfd for that.

Sir, that is a very poor choice. I know that you mean well though.
 
I put an American Rotary in my shop to run some 3ph bandsaws I bought from a machine shop. Its the most simple way to do what you are trying to accomplish. The lathe should have a transformer to step the voltage down to run a light, DRO, coolant pump etc.
Wire in / supply single ph 220 and that's all you have to do..

Mark, I didn't need to step down any thing as I never had a situation that I needed flood coolant.

I run my Logan on a Grizzly. My Logan is a beast and it runs great. Grizzly actually sells one that they have made in Missouri. I have no complaints. I don't know why you're calling it a poor choice.

I'm glad that you are happy. I don't like that for one, they are 70% efficient. I can send you the steps and help turning yours to a rotary.

That's cool. All I can say is it was super easy to hook up I haven't had any problems and my lathe has amazing torque it's a five horse. So, it works great and I've never had any problems with it. I really don't think it's poor choice. I'll just say that.
 
It's Chinese right?
M300s were China some other Harrisons are not. I always wanted a 10AA
Not all M300’s are china. The early green ones were from the UK then they went through a transition. At some point in the transition they were painted white. Current white ones are from China. Some early white ones were rumored to be from Taiwan but I could never confirm that. Clausing refused to provide any info about where they were manufactured when I inquired years ago.

I’ll add that even though they currently are from China they are very well made.

All of the Harrison AA’s I’ve seen were from the UK and were the same green as the UK M300’s. A friend had one. I should have bought it when he wanted to sell it. Headstock is a bit too long to chamber through the headstock. It can be done but you’d have to do the bushing method like Jackie Schmidt or Bruce Thom of BAT.

They went to china for a short time. All the newer ones are Taiwan. MSC will give you any info you want on them.
 
I had 3 phase at my old shop. Now I run my stuff on a Phoenix rotary. I almost feel like the lathe is even smoother. Id say to get one twice the size as your largest motor. Super easy to hook up and runs quieter than my lathe motor. When I bought my new lathe I was told a static converter will void the warranty. Why, I dont know.

They only get the motor turning with 3 phase by use of a capacitor. Once it's running the motor is crippled and running single phase. I can't imagine it would be very smooth
