Ingersoll Rand 1hp 8" Grinder

[flippin]

Hey Gang, a while back I found an Ingersoll Rand grinder for sale online. It was quite a ways out of town, but the deal seemed good enough ($75) that I asked a friend to swing by and pick it up for me. Well my schedule has prevented me from getting it till now. Holy ****, I had no idea how big it was. This thing is a beast and it was all I could do to lift I up to the tailgate of my truck. There is no doubt that this is the quietest grinder I have ever used. Furthermore the wheels ran forever after the power was cut to suggest that the bearings are in good shape.

Kinda curious what people suggest for wheels. I tinker mostly and don't have any major fabrication plans in the future.

Despite my best efforts web mining there doesn't seem to be very much info on this industrial grinder. If anyone has anything to add good or bad it would be appreciated.

I have no knowledge about it whatsoever, but at $75, I think you made off like a bandit. I have a 1/3rd horsepower at home, but use a 1 hp grinder at work. And man, can you tell the difference. Dont get your fingers caught in it!

re-badged Baldor. Nice score!

Very interesting that it has the same amp draw as my 1/2hp Baldor!

As communicated I don't know much about the grinder other than it was originally made by Miller Falls. Are you pretty confident that it is a Baldor? The grinder is really massive for an 8". Thanks in advance

Millers Falls grinders were made by Kingston-Conley, but your I-R was made by Baldor (looks like an early 8100W). The model number even looks like a Baldor number. Trust me, you got a screaming deal.

The top wheel guards are gone but the bolts are there. Consider making some. They help prevent a broken wheel from hitting you in the pecker.

Throw away the grinding wheels and use a flap disc on a 4.5" angle grinder.

Then remove the gaurds, place in a box in a safe place, and put a 3M deburring wheel and the 3M radial bristle brush on the other side. Or even a good wire wheel.

Grinding wheels are for old men in the 1960s that try to sharpen lawn mower blades but just gouge the **** out of them instead.

You grind HSS lathe form tools with a 3M deburring wheel?

Flippin you ****!

Well, shoot. You got me there. Just used to CNC I guess.

Thanks Dave, love the idea of using synthetics. I have a bunch of angle grinders which I use with flap-discs and love the performance. I am insufficiently experienced to use grinding wheels without feeling like I am wielding a crude instrument. Traditionally I have used my bench grinders for cleaning up after cutting, removing rust etc. With this "new to me" grinder I just wanted to consult the GJ Braintrust for advice on setting it up. Now here's another question. I will follow your advice and purchase 3M deburring wheels (scotchbrite?) as well as 3M radial wire brushes. As mentioned my bench grinder usage will be for the most part restricted to cleaning, deburring, rust removal etc, how would you best setup the 8" IR and a 1/2hp block grinder to compliment each other? Should the deburring wheels go on the more powerful IR and the radial bristle on the block?

Thank you so much for your help?

Exactly. 500 or so different grinding wheels available, and they all have only one purpose. To sharpen lawn mower blades. Thank you for removing the scales from our eyes.

I have a 10" 2hp with a steel wire wheel and a brass wire wheel.

I have a Baldor 6" 1hp with deburr and bristle. No guards.

I have Cman block 6" with very fine wire wheels for delicate. Full guards and glass.

Have 6" Boice Crane that's getting flap wheels. No gaurds.

I have Baldor 8" like yours with full gaurds, glass, and lights and coolant holder I'm restoring right now. It has grinding wheels and I never used it. Don't want to sell it b/c all the pieces are there and its in good condition.

These are used for cleaning up old stuff AND working with new material.

Granted, I also have 2 Burr Kings, a Foley Belsaw, 12" disc, and a 6x48. So, I wouldn't use a grinding wheel.

****...sorry 404. What do you do with grinding wheels? It seems there is always a better option...

 

[flippin]

Dave, your comments got me thinking and it's funny, despite having grinding stones at my disposal, I head to the disk/belt sander combo far more frequently for any "grinding". Now based on your recommendation I will convert my "grinder" to a "buffer" by removing the guards. Obviously in the absence of the protective shields greater caution must be excercised however how much "fire" will I be playing with? Also given the 360 degree access to the deburring wheel and bristle brush should this now be mounted to a pedestal?

Again thanks so much for all of the collective knowledge.

No problem I was just returning the sarcasm. I sharpen tools. Remove large volumes of hard material like the mushroom top of a chisel. With a powerful grinder and a coarse wheel metal removal rates are high. Wheels lasts a long time. A wheel material can be chosen to reduce heating of the metal being ground.

Grinding with wheels is a huge area of specialty far beyond anything I do. I don't have a surface or cylindrical grinder at the moment

If you are going to use a grinder to sharpen tools, keep in mind that most wheels that they come with are aluminum oxide based which will suffice for most tools but any chilled iron or brass tools will need silicon carbide wheels. A grinder with a quench tray and variable speed will make a world of difference - nothing ruins an edge on tools like blued steel (overheated due to friction, won't hold a good edge again).

I have a Baldor 6" 1hp with deburr and bristle. No guards.

Damn, I don't think I've ever seen a 1 hp 6-inch grinder

 

[Mohawk Dave]

Damn, I don't think I've ever seen a 1 hp 6-inch grinder

oh oh....i just checked, it's a .75hp and was sold as a 7" grinder. I'M A BIG LIAR!

 

[tedsters]

that was definitely made by Baldor, and the guy that could probably tell you the story behind it would be ww11jeep i don't know how he finds all the info on these older grinders but he does, BTW thats a great find for that price whatever you do use it for it will be great

Agreed. I have an ever expanding selection of wheels from people who get tired of them.

( 'E's passed on! This parrot is no more! He has ceased to be! 'E's expired and gone to meet 'is maker! 'E's a stiff! Bereft of life, 'e rests in peace! If you hadn't nailed 'im to the perch 'e'd be pushing up the daisies! 'Is metabolic processes are now 'istory! 'E's off the twig! 'E's kicked the bucket, 'e's shuffled off 'is mortal coil, run down the curtain and joined the bleedin' choir invisibile!!)

So I have more choices than I know what to do with.

With sincere and profound respect, for those amongst us that have had the chance to use both conventional grinding stones and applicated abrasives (deburring wheels, sanding discs/belts etc) what are some of the situations best handled by conventional grinding stones.

Thank you so much again for the shared knowledge.

I haven't had a problem with "playing w/ fire". Even when bare skin hits the deburr or the bristle, it doesn't take skin off (You'd have to jam into it to do so).

Mine's on a pedestal. I would say yes to pedestal because everytime I use it I'm moving the workpiece in/out/up/down/around/circular etc. If the machine were on a bench, it would defeat a lot of the purpose.

Or do the cool trailer hitch thing onto a bench if you need floor space.

I just hooked up this one at work and man is it nice. If you look the guards and tool rest are the same as yours. I would definitely look in to the top wheel guards, you might be able to use the new grinder parts.

I've never used a surface grinder with anything but a conventional grinding wheel. Seems to be a good application for them.

Ha. I doubt my skill level or appetite for disaster will ever include a surface grinder in my lifetime. Oh well if Jeopardy ever has a question "best type of abrasive to use on a surface grinder" ........"What is a conventional stone, Alex"

Thanks!!

Flap wheels are great for polishing and rounding surfaces, useless for shaping. I keep one grinder with hard wheels and one with a brush and a nonwoven abrasive. They all have their uses. For lawnmower blades, just use an angle grinder.
