Craigslist Pedestal Grinder - Baldor?

[sbosecker]

Bought a Pedestal Grinder off a Craigslist ad today. All I've done so far is make sure everything works properly (seems to) and take some pictures.

The gentleman that sold it to me said it had belonged to the local county's education system before he bought it. I don't think he had had it very long.

Obviously some parts are Baldor (pedestal, lights/safety shields) but I can't say for sure that the grinder itself is due to the red paint and missing Manufacturer's plate.

Any way to determine the manufacturer of this grinder? There is what appears to be a sticker with a wiring diagram low and on the back of the motor. If I enhance the picture I took in photoshop, I can make out some writing. If some one has a Baldor grinder from this vintage with an original wiring sticker, I'd appreciate it being shared.

Looks very Baldor to me. Nice setup. See if you can find a casting mark somewhere to verify.

 

[sbosecker]

I just took off one of the covers...

Appears to be a 3/4-inch arbor. Maybe room for an 8-inch wheel but 7-inch seems more likely... I don't know how much clearance is normal.

SB: it looks like you have an 8 inch baldor and maybe a 3/4 HP or at least a 1/2. how does it run? i'd make that a dedicated wire wheel grinder or a stone and wire wheel.

i also like the original cast iron Baldor stand that i think was about $350 new. the lights were also about $350 or more for the pair new. even if you have to spend a little time cleaning it up and maybe putting in a new pair of bearings you did good buying that one.

post it in the vintage tool section on the vintage grinder thread either as is or spiffed up.

 

[sbosecker]

There's a well worn wire wheel on one side and this 7-inch grinding wheel on this side.

This grinder was advertised as a 6-inch 1/2 hp Baldor Grinder. It seems to run smoothly and doesn't bog down when either the wire wheel or the grinding wheel was used briefly. It took about 40 seconds to spin down after the switch was turned off.

SB: here's my 6 inch Baldor i'm going to spiff up and a 7 incher i sold a couple years ago that i kept the lights from. they both look smaller than yours so maybe take a measurement of the inside of the guard to see if anybody has their baldor handy to give you.

i'm not 100% that your grinder is a Baldor, but if it isn't it is a quality one with those cast iron wheel covers and tool rests. not to mention the cast iron stand and the Baldor lights.

It looks nice a nice machine but I don't think it's Baldor. The tool rests, guards and base don't look quite like Baldor to me.

It looks a lot like my 712, except mine doesn't have the exhaust guards.

 

[Strouty]

It looks similar to my baldor from the side. It even has the two bolts placed identically.



The base looks different, but yours looks older.

[bluebolt]

A 612R is 6" and does not not have exhaust ports.

That is probably either a Baldor 7306 or 7307 7" wheels.
I measured my 8" Baldor and I has 9" where yours has 8"

Does the wiring diagram have 115 or 230 options?

 

[bluebolt]

And check out Sheriff Roscoe's rebuild of a 7" Baldor.

[tedsters]

its a 3/4hp 8in baldor its identical to mine the grinder anyway the 3/4in shaft is a dead give a way and the exhaust ports
and the 7in is a 5/8 shaft 8in=3/4 10in=7/8 the shaft will determine the hp

Bluebolt,

My wiring diagram sticker is painted over. I took a picture of it and I'm able to make out a little bit of the lower left writing. I am hoping someone will fulfill my request to take a close-up picture of their wiring sticker. Then I will have something to compare to and maybe I can see if there's a match or not.

Best regards,

Scott

tedster,

Could you take a close-up picture of the wiring diagram on the rear of the base of your grinder and post it?

Best regards,

Mine is 1 1/2 HP, 8" grinder, what size shaft would it have? I have not measured so I am seriously curious.

 

[tedsters]

heres a pic, btw ya got a nice set up

 

[TapperMan]

This is a 1959 Baldor that I bought from a university surplus shop. The switch on the base looks similar.

 

[tedsters]

to be honest with you i could not find even what wheel size goes on yours just the hp and belt size but the regular grinder with 2 wheels the hp and shaft size are pretty easy to identify by baldors site, you got me curious now i will have to investigate a little ya got curiosity going now

 

[Strouty]

Sorry

 

[sbosecker]

heres a pic, btw ya got a nice set up

Thanks for the kind words & the picture...

It looks like we may have a match.

It is difficult to say since there is so little visible in my sticker. I have a couple of images that I punched up in photoshop. One is in color the other black & white.





Looking at the bottom left corner.

Lowest line: Word appears to be "Caution"

Next line up: Word appears to be the start of "Connect"

Next line up: Word appears to be the start of "When"

Best regards,

is there any info on the back side of the wheel guard cover at all on the casting or inside the wheel guard anything that may even look like a small clock

 

[sbosecker]

A few more random pieces of information:

Inside the dome on the inner side of the cast wheel guards are numbers. The one that covered the wire wheel was the easiest to read. It appears to be 88-106. The "88" could be "BB" or "B8".

Above that is some other sort of stamp that might be a date stamp of some sort.



Just above where the missing Manufacturer's plate should be is a painted over sticker. By holding a light just so, I believe I can see the U and part of the L of the UL symbol. I have seen this UL sticker located in this position on other Baldor grinders. The following picture shows (poorly) each leg of the "U" of the UL symbol (see arrows pointing at legs). I can see it better than it photographs.



The 7-Inch Grinder rebuild referenced (and linked to) earlier in this thread, gave a value for the distance between a couple of bolt holes in the Wheel Guard. The value for the 7-Inch grinder was 7-1/4 inches. My measurement between the same two holes is 9-inches.

 

[sbosecker]

OK. Here's the wheel guard off of the wire wheel side.

That's one fully depreciated wire wheel!

Scott

tedsters,

Well I didn't get the New Old Stock brand new in box deals for $50 that I read about here but I'm happy enough with the price. Ha!

The guy was about 10 minutes away from me and I paid $350 for the setup.

Best regards,

Scott

 

[Strouty]

That is a fair price, especially with the pedestal.

it will last long enough to be handed down thats for sure, did you ever figure out what rpm it is yet

 

[bluebolt]

That's G8-106
From parts list for 8107 8" grinder

[Outlawmws]

Well BB nailed it down, but honestly if the 8" wheel clears, it's an 8"...

Nice score!

Tedsters,

At this time I have not determined the rpm of this grinder.

I've been examining the wealth of pictures and such of Baldor Grinders on the internet. Based upon what I had seen, it seemed that my grinder had been produced sometime before the 1980's but later than 1960.

Today I see on eBay an auction that will end in a few days. It looks pretty close to my grinder and there's a nice shot of the Manufacturer's Plate with a serial number (F679) that might indicate it was made in 1979.

Is my assumption correct about the serial number being a reference to 1979? Pictures that I gleaned from the eBay auction are attached.

Best regards,

Scott

 

[sbosecker]

There appear to be several layers of paint on the grinder that I acquired.

During the 60's & 70's did Baldor ever use a greenish paint on their grinders?

Scott

 

[drivesitfar]

SB: yes they had sort of a light green for a few years on their grinders. you should see a few of the green Baldors in the vintage grinder thread and WWII seems to have the history memorized. i also think he made a post or two telling us what the history of Baldor was.

 

[tedsters]

i had a 6in baldor that was a 1954 the original color was green had the carry handle on it

 

[sbosecker]

...did you ever figure out what rpm it is yet...

What an age we live in that one can have a package delivered - by the United States Postal Service! - on a Sunday. Amazon.com, like glaciers & tides, is an amazing, irresistible force if it can accomplish such a thing.

Today I received a non-contact tachometer from Amazon. I had been thinking about getting one of these and the question about the grinder's rpm pushed me into action.

I wrapped a bit of black electrician's tape around the grinder's shaft and then placed a small square of the reflective tape included with the tachometer on the black tape.

I flipped on the grinder's power switch, pointed the tachometer at the shaft and pushed the "TEST" button. The laser illuminated the shaft and a number quickly appeared in the display.

Although I don't really have a feel for how fast 3600 or 1800 rpm is, my instincts while testing the grinder was that it was the slower of the two possibilities. This was confirmed by the rpm readout of around 1800 rpm.

Looks like my grinder is a model 8100W that's 35+ years old.

Best regards,

Scott
