Milwaukee Bench Grinder?

[PBCampbell]

After many years of wanting a decent bench grinder, today one falls in my lap. A "Heavy Duty" Milwaukee, model V-101, 1 HP, single phase, dual voltage monster of a grinder. 10" wheels, 2+ feet of width, and a good 100+ pounds my sore aching back says. Now for the questions. It needs a new power cord, as the "welding cable" sized one on it has serious cracks. At 11 amps on 120v it will need a dedicated circuit. I'm pondering as to just go ahead and rewire for 240v, any reason to go for that extra expense? I'll have a 40+ foot of run to add in for this new circuit, so not a huge extra expense. There is a slight RPM difference according to the tag if I'm reading it right, (1425/1725), or is that maybe related to the cycle as it also lists 50/60 hertz. That makes more sense, but just to be sure...
Needs eye shields and rests, so if anyone could point me to links showing what these may have looked like, I'd appreciate it. The right rest bracket looks original, but everything past looks cobbled up. Left rest bracket is broke off. Eye shield brackets are different and neither look original given the extra holes in the guards. Good point is the wheel guards appear original and intact and the monstrosity does run.
serial number is 103-1230-cx-c if that helps. Frame is e66s and number below that is 14n or 11n, I can't sort out what that is for as tag is difficult to read.
I appreciate all and any replies. My apologies for no pictures, hopefully in the near future I'll figure out a way to do that.

Thanks, Pat

pics?

Pics will hopefully come later when I clean this big dog up. I don't even know how to get pics on the computer yet, let alone upload to the internet, lol. This is already looking like a lot of work, HaHa.

I think at different times Doerr and wissota supplied those. If you look up the wissota bench grinder thread there is probably some useful info in there and the member that started that thread knows a ton...

In short, yes the 1425/1725 is difference between 50/60hz. The number of poles determine the speed. AC power in the US is 60Hz, so unless you install a VFD the speed will be 1800 under no load, then 1725 loaded. 4 pole motors are calculated to turn 1800 rpm.

The formula is the number of cycles (Hz) times 60 (for seconds in a minute) times two (for the positive and negative pulses in the cycle) divided by the number of poles.

(60 x 60 x 2)/4 = 1800 (1725 under load)
(50 x 60 x 2)/4 = 1500 (1425 under load)

Thank you for confirming that Gearhead1. I suspected that, but I believe that's the first motor I've ever seen spec'd that way.
I've looked through some threads per 1982FXR and it resembles a Doerr grinder moreso than a Wissota.
I really need to get some pictures and get those uploaded. By this time I should know this, lol.
To be honest this is the first good score I've ever had and it was within walking distance. The real score for me is a Craftsman GT18, but some bits are missing so I'm on to other forums to try and see what I need to be looking for there.

Having recently sold my Wissota-made Milwaukee 10-inch, I can tell you it weighs about 80 lbs (not 100) and the current draw is about 8 or 9 amps (can't recall exactly). Yours is most likely made by Doerr.

These might help with the eye shield configuration.

No tool rests came with the CL find.

It's a 1 HP, 60Hz, 115/230VAC.

These might help with the tool rest design.

1/2 HP, 60/50Hz, 115VAC.

Yeah, I think I got pictures up, lol. What a pain, lol.

Only thing not showing up is the serial number at the bottom of the tag. It's 103-1230-cx-c as best as I can tell.
I'm pretty sure it's a Doerr from what little I've been able to find on the internet so far. The bulk of old grinder info is on Garage journal it seems.
Much of the left side eye shield exists and a good bit of the right side rest is still there, so I at least have some idea as to how to replace whats missing.
It was mounted on a commercial (restaurant) table pedestal which I think I'll add some sort of top to as it has some weight and a wide base to prevent tipping.

Thanks to all who've given info so far and I'll appreciate any additional info.

I have a V-121, which is a 7" Milwaukee grinder. I looked for a V-101, but could never find one. Very nice. You can see mine in the vintage grinder post.
