let's see your craftsman block grinders

barney rubble · Nov 18, 2012

I bought a 1/3 HP from a guy at a yard sale last summer for $5.00. He plugged it in to show me it worked and said the only thing wrong with it was it spun for a long time after you shut it off. lol.

In restoring these grinders, is there anything which should be done to the armature and stator? I'm seeing some light rust on them in places, but I'm kind of feeling that since it worked before, I shouldn't do anything to it. Last thing I'd want to do is screw up the motor!

Teter09 · Nov 21, 2012

Has anyone done anything to clean the armature or stator? And if so, what?

Jim C. · Nov 23, 2012

I'm not sure if this qualifies as a block grinder because the shape of the motor housing is a little different than most of the others depicted in this thread, but I figured I'd post a couple pictures anyway. My dad bought this grinder new back in the mid 1970s.

Found this one on Craigslist, 100+ miles away. Seller still had it a week later when I was making a trip down that way. So, 30 miles out of my way, & $30.00. Guess I did ok. Model 397.19391

nine4gmc · Nov 26, 2012

anyone ever see a block grinder style tool sharpener? I just ran into one yesterday but the guy didn't want to sell. Looks a lot like a block grinder but has no outside covers and the label has tool sharpener instead of grinder.

Confusing to say the least- current draws:
1/4 HP -257.191200 - 4.9 Amps
1/3 HP -257.190170 - 2.1 Amps
1/3 HP -397.19580 - 3.5 Amps
1/3 HP -397.19391 - 4.7 Amps
1/2 HP -397.14460 - 3.1 Amps *
1/2 HP -257.191401 -5.1 Amps.

Numbers taken from pictures previously posted.
Theoretically,
1/4 HP = 1.55 Amps
1/3 HP = 2.07 Amps
1/2 HP = 3.1 Amps. *

Even assuming less than stellar efficiency, some of the numbers seem odd.
I do have a 1/4 HP motor on my scroll saw that draws about 4.5 amps, measured. Doesn't vary much from no load to full load either.

Odd, I say, Just ODD.

GarageEnvy · Dec 5, 2012

Guys, I need your sharp eyes. I'm looking at this

http://fresno.craigslist.org/tls/3455845838.html

I called the guy and he really couldn't provide much information. He didn't know the HP but thought it was 1hp because it was the same size as another one he had. He didn't know the wheel size either. When I asked if he had the wheel guard, he said he had a wire wheel on it. He thought the brand was Baldor but then called back to say it was "industrial".

So does anyone recognize it? Is it an old block grinder?

87Pomona · Dec 5, 2012

The other wheel guard looks to be stored under the table/stand.

87Pomona · Dec 5, 2012

Looks like a Craftsman to me.

You didn't do good you did OUTSTANDING. I have exactly that grinder and it is great.
Mine needed new bearings and I paid 45 now with new bearings it is just great.

It is an old round top block grinder. The guard is beneath it on the stand. As long as it doesn’t make any heinous noise it is worth $50

You can almost see the crown logo in the photo.

buy it NOW!

PipesTA · Dec 12, 2012

Here's my Craigslist score for today. $40 with the stand. 1/3 HP. Stand has a bit of overspray but it should clean up. Came with a drill grinding attachment. Please forgive my crappy cell phone pics. A little elbow grease and it'll be as good as new

emeraldcoupe · Dec 12, 2012

nice!

Sure, any particular angles or shots you want? It came with some papers, let me see what I actually have.

You got a good deal on the grinder/stand!

barney rubble · Dec 12, 2012

So I quess some of these actually have a brake system on them. Never seen one of them. How do they work?

87Pomona · Dec 12, 2012

First time I've seen one with a brake. Let us know how it works, when you figure it out of course lol

PipesTA · Dec 12, 2012

Flip the switch over to break and it slows down, that's how it works

look at the rear grinder in the top picture of the first post on page two.

I no longer own it.

90 deg straight side view, and a couple angles. If you have a scanner you could make a PDF of the instructions and I'd PM you a real email. :thumbup:

1950's Craftsman Block grinder I picked up today, my x-mas gift

This thing is huge compared to my 1974 Craftsman Block Grinder. It will get a full restore when time permits.

Found on Craigslist and had to drive in a snow storm to acquire this beauty:

ShadowRuleZ · Dec 29, 2012

Nice, there are a lot of guys looking for the elusive 8" wheel and/or 1 HP models.

Another amperage figure (7.6) to add to the list from the previous page:

mcmlvif100 · Dec 29, 2012

Craftsman 1/3 HP. Craigslist find. As purchased / not cleaned up yet.

Anyone have information on the disc sander attachment? Haven't found any manufacturer's identifiers.

nine4gmc · Dec 29, 2012

893cv, what's the base look like? Good score!

Holy **** Shootingblanks, I would have walked both ways uphill in the snow storm for that 1hp!!!

And mcmlvif100, that disc attachment looks kinda DIY but I would rock it!!

You guys all scored, good posts!!

Teter09 · Dec 29, 2012

Here is my follow up to my original post #101....

The 1/3 HP has been torn down and repaired a few items and turned it in to a Christmas Present for my father. Hopefully he liked it, he didn't say much about it when he opened it.

View media item 27118
View media item 27119
View media item 27120
Next up is that 3/4HP from the same post #101! :evil:

Edited to add colors:
Rustoleum Hammered Copper and Rustoleum Ivory all in one Paint and Primer. The Ivory is over a base coat of Rustoleum all in one Flat White to help the Ivory be true.

Part of the difference may be split phase vs. capacitor start motors. I have seen small fractional HP split phase motors take very large amounts of current. One 1/6hp motor used 9 amps unloaded or loaded. I presume the power factor was very low unloaded and increased with load.

Teter09 - nice job!

What colors did you use, very good combination. :thumbup:

Thanks Torqueman! I couldn't have done it without your other thread and the label!

I wound up using Rustoleum Hammered Copper and Ivory. Though I will say, I had to use a bit of Hammered White Primer and Paint All-in-one instead of my other primer (which is gray). For some reason the Ivory does NOT cover at all, despite multiple coats, it looked more like a clear coat with glitter! So I had to sandblast the eye guards twice in order to get them right.

MrKona · Dec 31, 2012

Here's my current project. This poor 7" grinder has seen better days... is currently disassembled. I'll give it new bearings, strip the paint and repaint it the original brown/gold, new glass, wiring, cord. It likely took a fall at some point in its life which cracked the glass and bent the shield frame (which I just straightened). When I disassembled it, I could also see a visible shaft wobble on the right side which measured around .01" with the dial indicator. A hammer, a block of wood, and carefully placed whacks later, the shaft is straight to less than .001".

I also have the original pedestal stand, but unfortunately, the pedestal table is missing a chunk of metal at one corner. If anyone has an "extra" original Craftsman grinder pedestal table, please let me know.

Factory date stamp is November 7, 1962.

I'll be sure to post an "after" picture when this project is done. Really looking forward to running this grinder.

let's see your craftsman block grinders
