Vintage Stanley Grinder Refurb

TBone69 · Nov 3, 2013

Picked up a bunch of vintage tools last year that had taken a bath from Hurricane Sandy.

First refurb of a Craftsman machinist vise went well so I next on the list is a vintage Stanley Type 677 bench grinder.

When I got it it sort of worked, it spun and ran when plugged in, slow but it ran. Just pulled out from under then bench and she was frozen up.

My plans are to get it running, cleaned up trying to keep original finish were possible, I like the "patina" look gives the tool some history.

I did the quick search for info on vintagemachinery.org but didnt find much, if you know of a good resource please let me know.

Here are a couple of pics before the tear down. Notice what I think is the homemade stands for the lighted shields.

Ok time to get started on the tear down.

Power cord and wiring shot as you could imagine due to age, dry cracked insulation. Removed the shields, home made stands and wheels. Buffing pad got chucked stone wheel not sure seemed to be ok will decide on that later

At this point I was trying to figure out on how to remove the inner wheel flanges as they seemed to be stuck.

Time for the Puller and lo and behold once the first inner wheel flange came off the grinder free'd up and now spins by hand.

The bearings must be seized, there are gettting replaced anyways, but this now gives me hope that this grinder will live again.

Once the inner wheel flanges where off I was able to remove the wheel guard, well the part that is still there anyways, guess I will have to keep an eye on for replacements.

Thats where we are for this weekend. Next to remove the motor from the base, it's just bolted on from underneath then move on to dissassembly and cleaning of the electric motor.

Wow, that is going to be totally cool restored grinder.

What vintage is this . . . 1960's ??

Really love the lighted shields . . . awesome. :thumbup:

Awesome. Great save. Can't wait to see the results of your work.

Tbone,

Here's my 1/2 hp Stanley with pedestal base. Let me know (PM) if there are any pics you need to help figure out where things go.

That is one cool grinder. I'm excited to see where this goes. :beer:

Should be late 40's- late 50's IIRC. In the 60's they changed to a longer more slender motor profile.

That is down right beautiful. :drool:

Great job on the restoration. :beer:

TBone69 · Nov 3, 2013

Thanks guys.

i am thinking mid 50's vintage as the Craftsman vise dates from 55 and if I remember correcly the Delta Rockwell drill press dates to 58.

I'm liking the pipe fitting eye shields. I wonder if that is factory. :dunno:

Steevo · Nov 3, 2013

Beautiful job. I love those old solid bar tool rest mounts, and the pipe-fitting guards are a cool addition.

No. If you look at his bottom right photo posted earlier, you can see the OEM eye guard mounting post and bracket on the left side, which was originally mounted on top of the now-missing wheel guard, as shown on my similar Stanley grinder:

The OP's grinder is a Model 677, which was sold by Stanley as an edge tool sharpener, hence the 1725 RPM speed instead of 3450 RPM. The left side had a conventional tool rest, and the right side had a clamping and grinding attachment for plane irons and chisels.

Thanks for the info WWIIJeep :beer:

Do you have any pics of the old Stanley catalogs? I can't seem to find any 40's or 50's stanley power tool catalogs online. :dunno:

This is about the only thing I could come up with. I've found a few hand tool catalogs, but not much luck on the old power tool catalogs.

The one you found is pretty good. What year is it?

Here's a 1956 catalog page showing the Model 677, with the plane iron and chisel grinding attachment:

45' I think. I randomly found it online. Do you have the physical catalog of the one you posted or just that image?

Ahhh Haaa, thanks for the info WWII Jeep.

I have the left side rest, it may be in the back ground in one fo the pics and it seems I have the attachment for sharpening chisels. I also got a load of chisels in the load of tools this came out of.

Well in that case, would you mind taking a few pics for a fellow OWWM enthusiast?

Mostly interested in the bench grinder section.

Whoa it's been almost 6 months since I last posted. This project has been languishing for far too long and taking up valueable work bench space.

Had some time today while my Wife is out with her Mom and Sister having a Mothers out afternoon.

The center motor cover had flaking paint so I stripped it down back in November.Today I cleaned it up, shot it with some primer then some gloss black.

The ends/bells were originally black crinkle coat and just needed some freshening up so hit them with a couple light coats of the same gloss black.

Looking forward to getting back on this. I have new bearings, wire, and toggle switch for the rebuild. Hopefully have this baby back up and running in the next week or two.

+1 Love that restored grinder, bj.

Actually, that's not a resto. The grinder is all original.

I stripped the pedestal and painted with POR15. I've been meaning to hit it with some semi-gloss or maybe give wrinkle a shot.

Rust · May 11, 2014

Great thread!
I'm on board.

Although my grinder is not a stanley, it is very similar.
I love the black pipe eye sheild brackets with the compression fitting disconect..never seen that before.
Very cool.

TBone69 · Aug 5, 2015

Wow I gotta get back on this project! Still sitting in pieces on the bench. Been busy restoring a 29 Model A.

I seem to have misplaced my wiring diagram anyone have one? This has the centrifugal speed switch.

TBone69 · Aug 10, 2015

Made some progress this weekend! She is going back together.

Thought I had lost my diss assembly pics when I lost a hard drive in my laptop. Still had a couple pics on my phone that helped. I also found wiring diagrams on the internet. Just search for split phase motor with centrifugal switch.

I had to replace and or extend the leads coming off the field coil. Then at some point during reassembly I broke one of the field coil wires. I lucked out that I actually found it before I got everything back together and I had enough slack on each end. Had to sand/scrape off the shellac, tinned the wires, slide on a piece of heat shrink and held the two wire ends together and touched it with the soldering iron real quick. I now had good continuity thru the coil.

Got it all buttoned back up and armature spins like a top thanks to the new bearings.

Still need to finish up the wiring and bolt on all the bits and pieces and she will be good for another 60 years.

How did you get the woodruff keys off the shaft to replace the bearings? When I rebuilt my Atlas grinder (same as your Stanley) a few months ago, it was the hardest part of the rebuild.

From what I recall, just a chisel or a punch and a hammer, once one end came up a bit I grabbed them with some locking pliers.

The woodruff keys on this grinder are half round. I have had square style keys in the past give me fits though.

During reassembly this weekend I accidentally put them in before putting the spacers on, Oops. I was able to pull them out with a pair of snub nose pliers with some effort.

TBone69 · Aug 24, 2015

Scored the missing left side wheel guard off of Ebay and after stripping 5 coats of various colored paint I shot it with some gloss black.

Also cleaned up the tool pedestal and tool/chisel sharpening attachements. Still need to rebuild/rework/rewire the lighted shields.

Had a spare wire wheel I threw in for now and used it to clean up the tool posts.

Runs smooth and is suprisingly quite, must be because it's built like a tank.

pendragon1998 · Aug 24, 2015

Looks great. Did you keep the wheel? I tossed all my original block grinder wheels. There was just no way to know how they'd been treated, even though they looked good, and I decided I would never feel comfortable with them.

TBone69 · Aug 24, 2015

I do need to get new wheels for it. This was submerged during Hurricane Sandy so the integrity is questionable.

It was just on for a quick test. Being that these are 7" wheels I will have to order them as most places only carry 6" and 8".

pendragon1998 · Aug 24, 2015

Look on ebay. I got some nice Israeli made wheels there, and they had a reasonable selection.
