"GJ and S" on wing nut - Garage Journal Stumper - they knew even then!

Edit to add the one in the drawing with the round knob on the mount clamp bolt looks a lot like a real old Craftsman I have, couple pics here http://www.garagejournal.com/forum/showthread.php?t=289921&highlight=Craftsman

Luther is another popular brand of those hand grinders, used to have one of those.

 

[Shiftless]

The clamp knob looks similar to the one on my Wissota (a common clamp on grinder) But the wing nut on mine is not labelled. I know that the tool rest on mine is missing. But considering I picked it up for a dollar at a local garage sale I can't complain. I did have to dress the stone a bit to make it look this good.

Snerk.

I agree, the round crenellated clamp knob on that Craftsman is a very close match! (That is a sweet grinder, by the way! Looks OD and military and possibly WWII to me.) But I've also closely matched the clamp knob to a Modern Grinder (Milwaukee, WIS) No. 00 Model B.

So maybe that feature is not a good enough distinguisher on these hand grinders.

Luther is a very popular brand, but neither the grinder in the manual or the green one I am trying to identify is a Luther. Here is a Luther I have:

The clamp knob looks similar to the one on my Wissota (a common clamp on grinder) But the wing nut on mine is not labelled.

It looks "knobbier" for lack of a better term (with fewer crenellations).

This is a long shot, but this is what is left of the decal that was on the green one. I forgot to include it in my initial post.

That's a great 7-inch grinder (I don't think 8" wheels would quite fit), and the same as I used to build my "Frankenstein" belt grinder.

http://www.garagejournal.com/forum/showthread.php?t=293283&highlight=frankenstein+belt+grinder

Lots of power, way more than any 1/2hp grinder I've ever used. You stole that one!

Thanks for the comments and info, I'll have to look at the size, I thought the wheels on it were 8" when I measured them but will check again. I did put on some 6" 3M Convolute Wheels and the right tool rest couldn't really reach in that far for proper set up.

Does anyone recognize the left tool rest?

Not sure what I'm going to do with it as I much prefer belt grinders over stone grinders, even convoluted wheels but it runs so well and quiet like my Blador. Interesting to know that these grinders were made by Kingston-Conley.

In the past I have praised Craftsman box grinders but have since sold all five of them, those pail in comparison to this grinder in strength and smoothness and to mu Baldors.

What you did to your grinder is brilliant and beautiful, now you have me thinking about what to do with this grinder. The cut off and belt grinder attachment would be more useful in my shop. I could see making cut off jigs and a table with a slot/guide for the jigs/holders to cut small items. G_P who posted his restored green Stanely on your thread is also very nice.

I wish the axels were longer because I like using this for flaps & bristle wheels without safety guards. I'm spoiled by my polishers with this setup and could use more but I'm not complaining for $10 purchase other than it's damn heavy.

Thanks for all the info and enjoyed reading your restore thread.

I have possession of my Grandfather's old Black and Decker bench top grinder. It doesn't work and I ave no idea what year or model it is. I am wanting to bring it back to life, but I need some assistance in my research. Does anyone on here have any ideas?

This is a Heavy Duty, 1/3 HP, 6" Black & Decker bench grinder, made by Van Dorn (Van Dorn was acquired by B&D and continued to make grinders/drills for B&D for years). I think it's a model 67. These were made starting in the late 1940's until the late 1960's. The tag suggests this was late 40's-early 50's.

Surprisingly, the tool rests are mounted to the wheel guards. The holes in the base are not used. I believe they were for an earlier design that was abandoned in favor of the guard mounted rests.

Parts are extremely scarce as these grinders are not very common; you'll be better off finding another complete grinder and stealing parts.

A word of note - if you do take this apart, be very careful of the brush holders. They are rather fragile.

It's a very nice grinder if you can get it running.

 

[454ragtop]

Welcome, can't help with the year, but at 110 volts, instead of 115, guessing 40's or 50's. First thing to check is the switch and wiring. Do you have the guards and tool rests?

 

[ndnchf]

I picked up this cool old grinder off craigslist on Christmas eve. I'm guessing 1930s - 1940 era.

 

[Outlawmws]

Any maker on the pedestal?

 

[ndnchf]

I just got it home last night, have not looked close yet. But I'll check it out tonight.

This one i dont think is super vintage, but it is older i believe. is there a way to date it? serial number is W4-85.

a year or two ago i asked my snapon guy if he had a bench grinder to sell. He told me he had this in his garage that he didnt use. I guess he had to repo it from someone that never paid for it. He dropped it off and wouldnt tell me what i owed him, and he kept saying dont worry about it for now. He still never let me pay for it. I dont think i could find a better snapon guy. He used to come to my dads shop when i was a kid, i always looked forward to the bowl of candy on his truck. hes known me as long as i can remember. Wish i had more money to spend with him though, i feel bad when the majority of the time its just a tool waranty!

i think im missing part of the rests? i have a carridge bolt on the one side that works okay, but theres gotta be somthing better!

 

[454ragtop]

Nitro, Wissotta made that for Bluepoint. Can probably get some rests from Baldor that would work, look into parts for their smaller grinders. Probably won't be cheap though. Easy enough to bend some up out of flat stock, fab them from angle iron.

Edit to add the W4-85 is probably a date code, April 1985.

 

[ndnchf]

Any maker on the pedestal?

The only markings I find on it are "CS" cast into it. Not sure what that means.

Other owners of this grinder have found parts through Wissota. They're still in business and only making ice skate sharpeners now but still stock some replacement parts, IIRC.

If you use Google to search [blue point wissota site:garagejournal.com] without the brackets you can probably find threads about this.

I know these Delta Triple Duty Grinders have been posted before but here is one I just picked up last night. It had been a pedestal grinder but the PO is using the pedestal to mount a restored police call box onto. I couldn't talk him into letting go of that. Also missing the side covers and the water pot but this thing sounds like brand new. It was manufactured in 1944.

Brad,

That's a really nice one, well done. I like the tool rest's a lot, they don't get better than those and of course the eye shields are cool.

Glad to hear it's still purring. Cheers

Brushes? The rpm suggests a 2-pole synchronous motor---no brushes.

I had the same grinder (branded Milwaukee) and the original rests aren't all that special. You should be able to fabricate something to fit. I would also suggest that you also replace the rest brackets as well, possibly like I've done for similar machines.

My 30yr old / 1987 Date Stamped Dayton 3/4 HP 8" Bench Grinder, bought new in the box this past summer off eBay... What a great find it was, so much powa!

It has those ports on the back you can hook up a vacuum system to, I usually just open my garage door to let the stuff blow out there...

Sorry for my mistyping (didn't mean to make it plural). It's part of the centrifugal start. Check out http://vintagemachinery.org/photoindex/detail.aspx?id=5570 for pics.

I think the original pieces were some kind of resin/bakelite(?). I have seen reference to and even talked to a couple of guys about this assembly breaking during disassembly.

*that said, I do not know if the design was ever changed, so there may be other variants of this? This style was present for 20 something years.

 

[dngrmse]

Picked this Grinder / buffer up from an old factory shop in Paterson, NJ. It's made by "U.S. Electric Tool Co." that's actually still in business. I'm going to hit them up tomorrow to see if they can date it for me. From a similar looking grinder on OWWM, it appears it may be as old as late 20s or early 30's. Definitely going to restore this one, just figuring out my plan of attack. It's a 3 phase, so looks like I'll be learning about VFDs in the next few days.

VERY cool find dngr! I one day want to find such a critter!

Maybe before sinking any money into it, hook it up to your 240v single phase and give it a spin to start (obviously wire-nut one of the unused legs so you don't shock yourself). Without a load is should be okay single-phasing just to make sure the motor works and bearings are okay.

It runs, and the machine sounds good. The seller started it at the shop. I just had to disassemble it to get it out of my tuck. I'm guessing it weighs about 200+ lbs with the pedestal.

Thanks outlaw, funny thing is I went to that particular sale to look at some metal cabinets which were gone by the time I got there. Then one thing led to another.... So much for downsizing, I recently sold off a few grinders but they just keep coming back.
Here's a pic of the cabinets- similar to a set I picked up a couple months ago.

wissota is still in business. they quit making bench grinders but still mfg. ice skate sharpeners. last time i checked, they still had some grinder parts in stock.

Awesome, that may be the coolest vintage grinder/buffer I've ever seen. Have 4 pedestal grinders now, don't need any more, but if I found one like that I'd snap it up in a heartbeat. Can't make out the tag, how many amps is that? Can probably get a 115 volt in VFD to run that, work out slick.
Congrats.

It's 1.8 amps

 

[454ragtop]

Something like this http://dealerselectric.com/L510-1P5-H1-N.asp would give variable speed and 115 volt single phase conversion.

 

[exmaxima1]

It's 1.8 amps

Is that 1.8 amps at 220/240 volts? That seems very low, maybe it's 440 volts. Hopefully it will run on 220 as no single phase (115) VFDs seem to output 440 (3 phase). What is that horsepower of that grinder? Could it be much smaller than it appears in the pics.....

Or use a 115v VFD with a 220 to 440v step up transformer.

The plate said 220, but wouldn't that be 1.8 X 3 due to 3 phase? (Not a 3ph expert)

 

[tool_scrounge]

The plate said 220, but wouldn't that be 1.8 X 3 due to 3 phase? (Not a 3ph expert)

Power (Watts) = volts x amps x power factor x 1.732

Power factor is between 0 and 1. It is 1 for purely resistive loads, which a motor is not. But most folks assume it is one for simplicity.

Power (horsepower) = power (watts) / 746

 

[exmaxima1]

The plate said 220, but wouldn't that be 1.8 X 3 due to 3 phase? (Not a 3ph expert)

I couldn't read the plate voltage, so if 220 it will be easy to find a VFD for it. And with about 1/2 hp, it will be a cheap VFD.

 

[Davefr]

The price delta among the Teco L510 family of 115VAC VFDs is pretty minimal from .25 HP to 1 HP. (about $10-15)

I'd order the 1 HP version. It's overkill for that grinder but you could use the VFD for larger HP motors if the need ever arises out in time.

 

[dngrmse]

Been ******* with work today, just saw the replies. Here's a better shot of the tag, and a shot alongside my 1/2 horse Baldor. It's actually not that big in size, probably looked bigger without a point of reference. So the concensus is that its a 1/2 horse?

 

[EOC_Jason]

So the concensus is that its a 1/2 horse?

I've given up trying to rate bench grinders by HP, I just stick to their amp rating. But if you doubled the amps for 110v it's 3.6, so that's like 1/3 to 1/2... Probably would be rated as 1/2 because it's 3 phase.

 

[GETRIDAONE]

What would be a good guess on HP for my grinder ?
