so I bought a mill

[evobuilder]

I just bought a perfect Rutland Mill model 26660530 and its 220. It came with a questionable phase converter but that is where my knowledge ends. I am not able to run 220 into my garage so I am stuck with 110. I have a sub panel but it only has 25amp breakers and cannot accept any higher amperage as my wiring to my detached garage isn't enough to hold more amps.

Is there a converter I can buy that will allow me to run this machine on 110 with mas 25a breaker or did I just buy a boat anchor (at least until I make a significant investment in my historic home and can bring in more power?).

It'd probably just be easier to change the motor on it.

Well from what little I could find this seems like your typical table top mill offered in various models from 110 to 3ph and even with power down feed. So I'll assume the motor just mounts to a swivel plate and runs the quill via a belt or two belts for speed selection. If that's the case you won't have any problem replacing the motor.

And to snswer your question you will not be able to do anything with the circuit you have now to run this machine unless the motor can be rewired for 120v operation.

 

[evobuilder]

so any advice on where to get a new motor? Seems to make sense, just new to this machine so some direction would be very helpful.

Take a picture. Also on the motor name plate there will be a "frame" number. All you need to do is get a 1 or 1.5hp 120 motor that matches that frame size and shaft diameter. I would also suggest you get a reversible motor as well. If you unable to post pictures send me a pm with your email address and I'll post them for ya if you like.

**** I just realized you're in Tustin. If you need a hand let me know and I'll come down and sort it out for ya, I'm in riverside.

You need to give us more information on what kind of motor it has. Pictures help.

 

[evobuilder]

just sent you a PM

 

[evobuilder]

I'm working to upload pics... I am considering selling, but would rather fix (eg replace motor) and make it work.

 

[LXCam]

E, I got your pm but you have yours set up so you can't receive PM's. I know exactly what you need, I have basically the same mill. I'll give you a call tomorrow afternoon.

let me look at my settings, but yes, feel free to call. - Eric

There are VFD's for the smaller hp motors that'll make the jump from 110 to 220. Looks like up to 1.5hp

So now you have a mill... Are you going to be Milling around?

 

[jmarkwolf]

Put a 110 to 220 VFD on it.

Easy peasy.

What he^^ said, or what LXcam said, or you could snag a free treadmill off craigslist, steal the motor (usually 1.5-3.5hp) and run an scr controller/bridge rectifier to power it. This is the "ghetto" way of powering this type of dc motor, but it works surprisingly well. It would help mounting wise if it's a belt drive, as you could rig up the mounting for it. Since you would probably need the mill to build a decent motor mount. I have a 1.5hp dc motor off of a nordiktrack treadmill on my grizzly 10x22, and it is much more capable than it was with the stock 110v motor. Not to change subject, but I'm a fellow evo owner as well

Well **** howdy, learn something new everyday. I didn't know they offered single phase 120-240 vfds like that. But the largest they offer is 1.5hp as you said but unfortunately he has a 2hp motor.

This machine? https://orangecounty.craigslist.org/tls/d/rutland-milling-machine-and/6415723387.html

no neat sig line

Holy smoly Dr. Watson, that'd be the one.

Damn, I wonder if it’d start it? Or try to find a 1.5hp 3ph w same frame only ‘cause 3ph motors are usually CHEAP, esp smaller ones.

You wouldn’t notice a 25% drop in hp unless you’re taking .250” DOC with a 2” face mill. I run my BP on a buzz box theoretically losing 33%

 

[evobuilder]

yep, that's mine. In case I can't/don't swap the motor, I will sell this one and buy a 110 machine.

 

[evobuilder]

the VFD is a cool idea. Seems like a really viable option and I don't think I'd miss the .5hp.

I only have 20amp breakers in my sub panel in my garage so again, since I am not a home wiring pro (not even close), I wonder if this will still be too much.

If these work, I would be really interested because I want to run a 220 TIG welder as well (obviously not at the same time

dont change the motor you can get a small vfd for under 200, probably closer to 100

 

[evobuilder]

changed the motor to 110 (same specs as 220 motor), bought a shaft adapter to covert the new motor from 7/8 to1 inch (came with a new keyway as well). Drilled the factory pulley from 24mm to 1" ID.

So...
I bought the motor for 120
I bought the sleeve adapter and keyway for 15
Paid a local machine shop 20 bucks to drill out the pulley

Now I have successfully converted a 220 Mill to 110 and lost nothing in the process except a couple bucks and increased amperage.

Time to move on to gear reduction on my new band saw.

Kickass bud, glad to hear you got it sorted out.
