That looks exactly like mine. See the extended lead screw supports, very unique.
Hopefully you will enjoy yours as much as I do mine.

I wish mine looked like yours. its pretty filthy and the table, although not beat up, is terribly discolored/ oily rust. I don't think it has been terribly abused, just terribly neglected.

These machines are very robust with hardened boxed ways. If it hasn’t been abused, it will clean up just fine

I have this vise and I am very happy with it.
TECO sells a similar vise of equal quality.

If you want to go cheap check out Shars other import vises.
I wish I would have seen your post Sunday. It looks very good, and I'm sure would have been perfect for me. Sunday evening I ordered a Kurt DX 6 it's already on the way.

It is moved.
We had the Hillman rollers if we needed them . But the dollies I made worked great. Not a problem.

Sorry for the double post.

One hitch in my plan. Or I should say the first.
It was wired up to 480 volt. The book says "most"spindle motors can be wired 240 or 480 the plaque on my motor says 480. Not sure if can be as easily switched to 240.
Does anyone have any insight on particular issue?

I’d take some pictures of the motor plaque. That plaque is the key to what motor is on the machine. Also take a picture of the wiring in the main box of the mill. And post those in the electrical section of this site. Some real sharp guys on that section. I’m confident you’ll get some good answers there.

nice mill. Sharp is a good machine. I like Japanese products. Always top notch in my opinion.

Attached is a picture. Not really any better in person.
It's definitely a one voltage motor I'm certain it's been rewound. Only three wires coming out of the motor. Wishful thinking I even took the top bearing plate off hoping I would find some more .
I have had two quotes for a rewind $2000 and $1100. I called Sharp to ask what a new motor would cost..... $$$? $1312 and change. Comes with the drive pulley.
I ended up talking not a technician. And in perfect chinglish, he told me that the original motors had problems. The shafts would vibrate and wear out. BTW not a jab to the Tiwanese fella I talked to. I have a english as a third language Asian wife. I do seem to have an ear ear for broken english.
I have the motor out now and was, in a weird way hoping I would find a worn out shaft to make my decision for me . It looks just fine. I haven't measured anything yet but it looks pretty good.
So as it looks to me cheapest route.
Transformer and 480 volt VFD.
Next rewind keep the VFD that I already have. And the likelihood that I will ever run this thing long enough to wear the motor shaft out is remote.
Then there is the peace of mind that would come with the brand new and improved motor. With the new drive parts.
It's a lot of money either way I go. But it's mine now.
