Have you seen this one.

 

[BurtEggley]

yes. Thank you. I am thinking the jet 5 amp 6" jet if it will fit, but I don't know the base size. If not then maybe the dw756 or dw758 because they will fit my stand. They have no light so I will need to add something there because the grinder and stand are in a darker part or the garage, but i can add a light above them if needed. The DW756 6" is 4.0 amps and the DW758 8" is 4.2 amps. Either would work on my stand. The old grinder is 2.8 amps and is a 6" craftsman. Who knows, maybe I can rig a stand that fits the press when I am not using it and have both the old and new. Kudos to anyone who has stayed thru this with me.

8" has draws more amps, but it's also gotta turn a wheel that's 33% bigger in diameter, which means that it's probably easier to stall, which seems to be a concern of yours. That said, if you let the wheel do the work like you should, the 8" will remove material faster because of the higher sfpm, all else being equal.

From Jet re JBG-6A for anyone who has the same question:

Per Tech Service the base measure is 9 L x 5.5 W inches.

From Jet re JBG-6A for anyone who has the same question:

But no one has the bolt pattern dimensions you needed.

Not sure if this is considered trolling, but I can't see why anyone would invest in a new bench grinder. A used grinder made in Taiwan (not China), much like those sold by Dayton, would be a great basis for a BELT GRINDER. Having used and built numerous belt grinders over the past 20 years I rarely ever use a wheel grinder.

You can buy a decent adapter for $120 and belts are much cheaper (and safer) than wheels.

My opinion is find a nice used one. They are out there. My 40 yo or so 1/4 hp no name made in Tiawan grinder that I bought new is starting to make noise. Decided to upgrade to a larger used grinder and put a wire wheel and buffer wheel on the old one. eBay prices seem high, some nice ones on Craigslist but I found this 1/2 hp Craftsman Industrial rated on marketplace for $50. Has the water trough also. Original owner passed and his daughter is selling. Suppose to pick it up Wednesday. Almost pulled the trigger on a 1 hp Dayton but this seller contacted me just before I did, after a week of waiting. A “brand new” one like this one with the additional cast iron base and tool post just sold on ebay for $270.

It largely depends on what you're doing.

A bench grinder is designed to sharpen and shape tool bits and drills. You need to change out wheels for different grits and compounds to cut various tools.

Bench grinder wheels being round automatically put relief angle and clearance into tool bits. You can dress the wheel to cut angles, slots, tapers and radii into your tool. The round wheel also gives your hands clearance for sharpening drills and chisels.

Belt grinders are better for shaping metal parts and removing lots of stock quickly. But they **** for sharpening and shaping tools. Ever try to grind a brazed carbide bit on a belt sander? How about a corner radius tool bit?

Bench grinder wheels are VERY long lived compared to belts as well. You can sharpen tools for literally years on one wheel.

You can also run a wire wheel or buffing wheel on a bench grinder.

If you're shaping metal, removing lots of stock or deburring saw cut parts, a belt sander/grinder is for sure the way to go. But it isn't a bench grinder.

I will also say I see a lot of people using a bench grinder "wrong". They just grind metal on it as though it was a bench mounted angle grinder. That isn't how they are intended to be used, and in that case, yes, a belt grinder is the better option.

Interesting!

That link seems to be a clone of the Multi-tool grinder.

Jesus, Mary, and Joseph! All of this chatter over a cheap freaking grinder. Just go buy one for God's sake. Also, I must say the tone of some of the comments explains why I come here less and less. Someone "kindly" told another that their father was full of BS. Well, that's lovely. I am getting tired of all of the people on-line and in person. Now that I am retired, a good week is when I only have to go out with the dullards and rude people in the general population once or twice. Less, if possible.

My experience of new box store and common online grinders not been that great, much lower power than expect from rating plus not as smooth running as some older units .
Another old used market grinder option is Black & Decker HD range . I got 2 of these, one is still in daily use in my autoshop and has been for over 2 decades, cost me 10 bucks (didn't have the spare cash buy anything high priced) and all I ever done to it was regrease bearings, replace power cord and add nicer grinding & wire wheels as tasks/use required . .
For sure OP doesn't need industrial spec but if buying new you going have dodge the mass of **** that saturating retail market .
Doesn't sound like used good route for OP in his location/situation so hopefully some of the reviews on new equipment will help him dodge the garbage and find the gems .
Always plenty of used bench grinders for sale, this listing made me look at what going locally and spotted a steal on a grinder on nice stand but unfortunately too slow and that gone, Nice stuff at nice prices used is a case of daily checking and acting fast .

Everyone is just having fun, except you, apparently.

Thought I might update. Found a dewalt tool arm that would work so ordered it. About $15. Then immediately four of the same grinder I have came up for sale locally in a 24 hour period, made reasonable offers and one accepted. Used the new dewalt arm on it and used its factory arm to replace my broken one. As soon as I get a chance, plan to replace the present stand and grinder with a two speed 8" bucktool grinder, and probably a rikon stand. In the meantime, the grinder I have now will work until some other projects are finished first. Sold the spare and it worked out fine. However I still don't get some of the prices people have on used equipment. I sold the spare for $15 less that I bought it for. Paid $45 sold $30. $15 was a fair price for the tool rest arm. There is a duplicate model, equal shape for a "bargain" price of $279 nearby. Gotta LMAO at that price. The $30 price was a give away deal to a young guy setting up his garage. Hey, we were all young and struggling once, right? Happy to help him. But the guy who wants $279, what the hell is he smoking (don't tell me.) So I am back to a functioning grinder again, although looking forward to a new one that has a low and a high speed. The low speed should work well when sharpening drill bits and chisels etc..

Yesterday I picked up a new-in-box Craftsman grinder for $50 on Craigslist. It is 1/3 H.P., 4.7 amps, model # 397.19391, made in 1976.

I was the first to open the box and I had to assemble everything except the wheels. I inspected the wheels and no damage, the plastic eye shields are crystal clear, and just to check for spiders I peeked under the hood and no critters.

Wow! You ****! Nice find.

That's a Sears cheapy and it probably is more handy than the craptastic HF 6" Chynermans i purchased for my rented shop.

My dad had that exact same grinder when I was growing up. Sears knew their market pretty well, and this was perfectly fine for the typical handy homeowner shop.

It worked fine for sharpening lawn mower blades or axes, and for dressing the ends of punches, but it was not powerful enough to do real work, and the guides were not good. I don't think I ever tried it with a wire wheel, but it would have been okay at it, I think.

More handy? How would that work, a third wheel?

Maybe there's supposed to be an arm and a hand that attaches to hold the work steady so you can use your own hands to scratch your, uh, noggin?

Kudos for the great find.

He said he’s in his seventies, and use tapers off with time.

Your father is full of BS. I picked up a Chinese grinder on clearance when a hardware store that was going out of business in about 1986. That’s forty years ago. Still works fine. That was in a residential situation. It’s moved a couple of times and is here in Az now.

I have a power feed drill press, 2 x 8" grinders and a large horizontal bandsaw bought in '86 = Taiwan, not Chinese. All still work just fine after many years of abuse. NOTHING was coming out of China then except Hong Kong and diplomatic students who played wicked table tennis.
