Show us Your Vintage Bench Grinders!!!!

[drivesitfar]

Just to clarify my post if your box has room to put a new 20 or 30 amp breaker then running a #10 wire to your new plug would be best.

When I had a Cincinnati grinder I think it was a 1/2 HP snd my buddy that worked on my Hondas needed a grinder. Since I had craftsman blocks, Baldor and a few other decent ones he asked for my Cincinnati and he now owns it and loves it.

It does have a 120 plug. I assumed the outlet it was plugged into when I ran it was a 220. Is it safe to try & run it off a standard 120 outlet without damaging anything? It does have a panel on the top. This is what is inside?

People have been known to wire a 120V plug with 240V, but it is unsafe and illegal. It probably won't hurt to try it on 120V, but just for a couple of seconds if it doesn't spin up to speed right away.

I did a little clean up. I don't think I'm going to paint this one. I like the old original look. I don't know what that red stuff was, but after about a dozen shop rags I got it all off. Here's some before & after pics.

 

[Outlawmws]

Since it has polishing wheels I'd guess the red stuff was polishing rouge

Found a stripped Baldor 712 today.
I have enough bench grinders, but since it's a Baldor...
Hey SOLD! I'll take it.
20 bucks, what the heck

Darn thing is missing everything.....
I guess I'll just run it with polishing wheels

For the past few months, I've been looking for an old beat up 8" grinder similar to my Wissota so that I can rob the tool rests, then sell off the carcass
Then I found this Baldor that's missing just about everything.....

Need a 5/8-11 left hand nut
Does anyone know of a source?

 

[Outlawmws]

A decent Ace should have that LH 5/8-11.

Just picked this 1/2 HP model up at an auction - Looks like I will need a replacement label.

 

[drivesitfar]

John: there is also a craftsman block grinder thread if you’d like to post up your grinder over there. I’m pretty sure if you need a label made they might know a member that can provide one for you.

Thank You

Went for a drive today to adopt this big 2hp Ford-Smith 3 phase pedestal grinder. Spent more in gas than I paid for it ($75).

Time to learn about variable frequency drives. Any suggestions welcomed.

Made in Hamilton, Ontario, Canada.





They were clearing out a ton of neat stuff, and I couldn't resist for another $75 2 boxes of grinding wheels, a McNaught Retractable air hose reel, and a 9" Bosch angle grinder made in Germany.

Look for a VFD rated for single phase input at the 2HP 3 phase load. The single phase input is important. There are other options, but without knowledgeable help, stay with the simple option.

 

[Davefr]

I'd be very tempted to try this VFD:

https://www.wolfautomation.com/media/pdf/ac-drives/tecowestinghouse/l510/teco-l510-201-h1-u-datasheet.pdf

It's single phase 120 VAC input. Your motor is rated for 5.2 amps and the VFD is rated for 4.3 amps with a 150% overload spec. First of all, I doubt your motor will ever consume 5.2 amps continuous except under extreme worst case conditions and possible start up which will likely be very short lived. (VFD's protect themselves after the 150% overload).

I use this exact VFD to power my 3 phase 1.5 HP DP motor with a 5.8 amp nameplate rating and it's been flawless.

Once you go beyond 1 HP VFDs, prices increases exponentially and you loose 120 VAC as an input option.

Thanks for the recommendation. I didn't realize 120v input was an option. I assumed 230v minimum.

Is the one you recommended not 230v input? See picture below.

L510-101-H1-U is 120v unit.​

Yes, that's the one I use with my 5.8 amp 3 phase 220VAC DP motor and it's been perfect.

My recently acquired and restored craftsman 1/2 HP Block grinder. All original lamp, shields, tray - A big shout out to MattBlast for the great job on the label!

 

[Isaiah6113]

Hello all,

Picked this up a few days ago Black & Decker 8" Cat. 74 Type H 220v grinder.

The right wear plate seems to be homemade, but I may have a replacement. Previous owner did a nice job with the eye shields. Stone on the right is basically new. I'll be removing the wire wheel. Made in Canada. I bought it to swap the parts over to a 110 I have, but looking it over I'm going to keep it as is.

Thanks for looking, Matthew

It’s been a while since I’ve been in this thread. That’s a fantastic job you did with your Craftsman grinder restore!

 

[JohnPa]

Thank You - I really enjoy pulling an old classic like this out and cleaning it up.

Restoration of 1940’s Thor pedestal grinder
Safety guards have been removed
I did find it listed in a catalogue, grinder was $100
pedestal was $39.

BDB, beautiful work, and welcome to the forum.

 

[ALTEREGO]

Milwaukee (Wissota?) Model 5051

Not that old or unique but hoping still a good user and worthy of this post. Just got it today.

This is what I can tell is missing so far:
* Tool rests
* Glasses for the safety guards

Did it have a duct at the back connecting both spark arrestors shields?

What else is missing?

 

[slowtwitch73]

I've got a tool rest for that if u want ^^^

Had plastic lenses for the guards.. they are pretty cheap.

Mine did not have a collector... was brand new when I got it. Have since sold it but found a few parts for it recently.

 

[Outlawmws]

If you replace the eye shields with plastic, use Lexan. EDIT - Acrylic is not safe.

 

[bbrown3979]

Found this 10 inch Black and Decker grinder, model 4330. Best I can tell its a Van Dorn clone, late 1930s to 1940s. Came with massive made in USA Surty shields. Grinder plus shields is probably pushing 160/170 plus stand.

No idea if the grinder is made in USA or England. Stand and shields are USA, but bearings are stamped England and it was purchased in Canada. I believe the fellow I got it from said he purchased it from someone who got it gov surplus at auction a few decades ago.

Now just gotta decide whether I keep my 10 inch Wissota or 10 inch Doerr to pair it with.

I was thinking polycarbonate, not familiar with Lexan, will have to look it up.

I have 3 sets of thick glass a friend gave me (he used to work at a glass shop. he cut them to size for me) for a vintage craftsman block bench grinder, how can I tell if it is safe to use for this purpose?

Thank you!

Hi SlowTwitch,

I will send you a PM about the parts you got. Not sure if I need them since I might end up using it as a polisher, thank you for reaching out!

I havent had as much free time as Ive hoped but I've gotten one of the sheilds all cleaned up and the rest of the grinder ready for paint in the spring (snow doesnt melt till April). The other untouched sheild for comparison. Im definitely keeping these for myself.

Good job. Are those shields happen to be magnified? That would be nice for my old eyes.

 

[TerrapinNeck]

Thinking about buying this grinder at an estate sale. I believe they're going to ask 50 dollars for it. It does start super smooth and runs very quietly. The tag is painted over. Can anyone identify it as a Wissota ? Thanks.

 

[seagiant]

Hi,
Had this dropped off as someone heard I had a 3 PH RPC and could run it.

Needs a rebuild, bearings are noisy, and Switch needs work.

No doubt will be a Torque Monster, when finished!

Hi,
Yep, guess it was going to get thrown out, and someone thought about me.

I forge knives for a hobby, so will rebuild it, and use it to grind off the forge scale, instead of using my expensive grind belts on my 2X72!

Straight wired it to test, and it runs!

You lucky dog. That would be the perfect tool to have for knives. Plus 3 phase. I don't have 3 phase but my friends never think of me like that.

Hi,
I built a Stone Age RPC from a 7.5HP 3 Phase motor and start it with a 1/2HP Washing Machine motor.

I've used it for a BP Mill and a Horz. Bandsaw, for about 15 years now.

Some good deals out there if you can produce 3 Phase!

Unfortunately they are not... or not yet. The glass is 3 layers, first two innermost pieces are sealed together and the outermost is loose. Swapping it out should be safe
