Ok, I just pulled it out and took a closer look. I barely even got to look at it earlier as the kind people loaded it right in for me. Wow what a beast. For a home shop this thing is pretty impressive. I struggled a little carrying just the grinder into the garage.
I fired it up and while it did seem a little slow to get going it did go right up to speed and is rock solid. No vibration even with the wire wheel and not bolted down.
So how do you date these things? The rockwell seems to have a 68 in the serial but no luck with this one. Man that little rockwell looks like a toy now.
-edit- ah I do see 780 as the s/n. I suppose that is 7/80 which seems about right. Not quite vintage but certainly built like it is.
Also kind of cool the exact same model is still being made with parts available. Might have to snag a quench cup for it although $43 is kind of steep.

Lafester, that is a great grinder! I have almost the same exact one. The eye shields are a little different. Do yourself a favor and swap the bulbs out for LED's. Mine had a missing shield clamp too. I was able to make a new one pretty easily. Let me know if you need a close up picture.
My 1/2hp Baldor of that same era spools up very slow as well, so I always give the wheel (or belt, in my case, as I mounted a Multi-Tool on mine) a spin with my hand when I turn it on. Those capacitor-run motors don't have much start up torque.
Maybe you could add a pic of the label so we can see the model number and specs.
........... I really want to mount my multi tool on this beast but it will take some time to modify....
Not sure what you mean. The MT comes with a mounting plate that should bolt right up to your Baldor. It does not require a thick spacer like a Block grinder does. I had modified my MT years ago to use 2x42 belts, and also made mine adjustable for angle by employing a sandwich type locking mechanism. I think the only issue you might have is if your arbor is 3/4" diameter, as I think the current MT is bored for 5/8"




I just purchased this buffer from CL this weekend. It seems to run well enough, although I have not put it under any load. It is larger than most that I have seen (65 lbs., 19" long, 11" tall). It has been repainted. The badge is 2 1/2" x 2", and it completely rusted so I cannot identify the make/model. Originally I was thinking it was an old Baldor, but perhaps it is an old Kingston-Conley. I can faintly read on the badge, going from top to bottom:
807A (model?)
1/2 (HP probably)
110 (volts probably)
50/60 (Hz probably)
1
2850/3450 (RPM probably)
5.2 (Amps probably)
180062 (serial no.?)
The arbor is 5/8". Would anyone know more about this buffer (probably repurposed grinder) including manufacturer, model, characteristics, and likely manufacture date? I tried to search for Model 807A and came up empty. I wonder if it is worth investing the time/energy into refurbishing it too, as I know some of the older ones are considered better than newer vintages.
Any assistance/direction you can offer is much appreciated.

I installed the multitool on the 6 in grinder and it fits perfectly. I have an exposed wire wheel on the other side so it really does have to work a bit to get up to speed. Seems to be plenty of power but of course I have not fully tested it yet. Honestly compared to the 1/2 hp block grinder I think this one wins. .

Can you show how you modified your MT for the 2x42 belts?
The aluminum socket has sheared away from the rivets that hold it in the bottom of the porcelain insulator. Looking closely at the picture I can see tiny bits of metal remaining under both rivet heads.
Maybe my neighbor installed the last bulb...It might not have been from some hamfisted bulb installer, it could have been vibration induced metal fatigue from a bulb bouncing just a bit due to an unbalanced wheel(s).


Looks to be 5in or so.You’ll love that setup. My Baldor w/MT is our most used grinder at the shop. I’m curious what the diameter of the drive drum is. My setup is about 20 years old, when the drum was attached with a Browning-style tapered hub, and looks a bit larger. What is your drive diameter?

^ Your Stanley looks almost identical to a Blue Point I picked up at an upholstery store sell-off late last year. Side guards were trashed so I have it set up like yours. Cannot for the life of me find the left-handed screw for the LH arbor.

If you need any bits, let me know and I can rustle through the box of parts with the grinder motor.I think they are identical. I have a blue point and i’m putting stanley lighted eye shields on it.
funny I just saw the ad for that in marketplace.
Picked this up from the state surplus warehouse yesterday. There is no switch though. Did people plug them into a switch box?

that’s the first block grinder i’ve seen without a switch hole cutout.
I just picked up a 6" Ford-Smith bench grinder which came with the table and vice for fifty Canadian dollars. I bought it from an old guy and he said it was made in the 1950's. I'm going to mount the bench grinder to a pedestal and scrap the table.
