Need help ID'ing this vintage bench grinder

[rolenrock]

Hi! I'm new to the forum, signing up to be able to ask if any of you can identify this bench grinder and have information to share about its inner workings. I hope to be able to restore it to its former usefulness so I can use it in my shop so I'm going to need to find specs, manual or service manual. I appreciate any help I can receive.

Model number starts with B so maybe a really old Baldor?

Are you sure it's worth your time?

This listing has a grinder with a BGA prefix. Cincinnati Electric Tool company. Might be a path to go down.

You don't really need any model info, just open it up and measure the bearings.

looks like a fun project .good luck on it.

I could see that being a Cincinnati.

I could see that being a Cincinnati.

I second this. Although it’s heavily modified, it looks very much like an older Cincinnati. I would figure out wiring first and then figure out what manufacturer it is afterwards.

 

[rolenrock]

If it is a Cincinnati, where can I find the wiring schematics? Also, it has four wires coming out of it, does that mean it's two speed? It turns over freely, the armature is good and clean, brushes are still intact. My hold-up is figuring out the wiring because the wires are "rotted off" the base of the motor.
Thanks for the help... Deb

You probably won’t be able to find the exact wiring schematics but most Cincinnati grinders were for industry using 3 phase 208V, 220V or 440V.

It’s not too hard to figure out but you do need a high amp switch or even better a magnetic starter. You can use wiring diagrams from any 3 phase bench grinder they are all built and wired very similar.

I can see this grinder becoming a money pit without a good finish. A new Baldor grinder will cost less that a total restoration. I asked about having and Old GE 5 HP rebuilt at a local motor shop. The cost was nearly double of the cost of a new motor. I bought a new US MOTOR. https://us-electricmotors.com/
for the safety of those who might be operating that grinder, it should have guards. I had a new grind stone explode on my Baldor. The guard save me from harm.

I agree that it is an old Cincinnati grinder. I also agree that it would be a huge waste of time---those old windings, cloth wires, sleeve bearings, and missing parts would be a nightmare. Invest in a better donor grinder for a restoration project.

While there's a lot missing to restore it as a grinder, you have the makings of a decent wire wheel or even a buffer ( although the arbors on a dedicated buffer are longer). The biggest issue is to determine what voltage it is wired for; the fact that there a four wires coming out of the motor argues that it may actually be single phase, dual voltage (110/220). Usually grinders of that class are three phase,as has been mentioned, but I would be surprised if they didn't offer a single phase version at one time or another. Either way, those leads look awful and should be replaced.

My STERLING drill-bit grinder. From a decade of neglect at the back of a warehouse to fantastic. Yes, it works as it was designed to. I built the grindstone guard. I had a grind-stone explode a few years ago, and I was lucky, that time. http://www.sterlingdrillgrinder.com/

Just couldn't pass this old orphan up today. So now another project ahead of me. My drill press is 99 percent finished, with photos to follow. But not now.

Is there a sentimental reason you are restoring this? I only ask because that’s a 90’s made in China or Taiwan unit. They work fine but you can find a made in USA grinder for pretty cheap. The craftsman block grinders are built better, durable and plentiful.

Check the data plate! It's a 1974 and made in the USA.

 

[1982fxr]

Ehh, where does it say made in USA, I don't see that part? Just a company name with USA after it isn't the same as the term Made in USA. If that's what it says?

I only see 197 on that tag, which I'd guess January 1997. Can you show closer pics of exactly what you're seeing? To me I'm with catcher1984.

I was looking at that, and assumed they would stamp or write on the last digit.

As is called out in this thread, his was a 1979. I am assuming we could not see the 9 that he could.

Info about a 2HP 10" DURACRAFT BENCH GRINDER???

Hi Guys, I picked up this monster this weekend. 40 bucks. 2HP, 10", 18.5 amps, 1725 rpm, 1979. Runs damn good. Got new wheels with it also. And it has that cool light and rickety stand on casters. I can't find any info on these. One thread says blatant knock off of name brand stuff. I'd like...

That's what it is, 1979.

Sorry I was assuming the year it was made since I’ve handled a lot of bench grinders. But the year doesn’t really matter it’s the quality of them. The plastic on off switch and the steel cast guards are the same ones they used for a number of bench grinders made in China/Taiwan.

Don’t get me wrong though a working machine is better than nothing, it’s just that there are much better options available. Especially if you are planning to restore and use it for a long time.

In the end if you’re happy with it that’s all that really matters!
