I am in the process of ordering grinding and wire wheels for a number
of bench grinders when I considered that I might want to ask what
others use.

So what do you like to have on your bench grinder and why?

Thanks

================
Given the abuse/misuse that most shop grinders get, consider
installing some belt sanders, possibly with the dobbie-pad belts
installed.

Let me know what you want to do with wire wheels.

I am going to shop for a stainless wire wheel. I have a 1/2 hp motor
and want to mount various wheels to it (wire, buffer, flap, diamond)
using arbor adapters. One i want to buy is a wire wheel, maybe 8"

Timely message. Just today, I picked up a 1/6 hp motor from Lee Valley to
connect via a pulley to a grinder I've had sitting here for a number of
years.

Is there a general speed that one would run a grinder? Would I be wiser to
attach a pulley with a number of steps on it? I expect to be mostly
sharpening knives and such, maybe a few chisels or perhaps some drill bits.

What is the speed of the motor?
What is the max speed of your grinding wheel?
Does the 'grinder' have an adequate guard?
Do you know how to calculate speed output using different pulleys?
These questions MUST be answered before you proceed.

My sharpening book recomends 600 rpm. Feet per minute would have been
better but it looked like a 6" wheel. Too high a speed and you'll burn
the temper out of your knives.

The wheels that came with it, because they came with it, and I haven't
wore them off yet. I know a lot of guys like the friable stone wheels
for sharpening, but you learn to have a light touch fairly quickly if
you use the standard wheels.

In a wood shop, I'd skip the wire wheels. They throw off little bits
of wire that can mess up a freshly sanded surface real quick. Great
in a garage or shed, though.

1/2 hp is kinda' wimpy for an 8" wheel. Why Stainless? You only use
Stainless brushes on stainless workpieces. Consider a pulley driven arbor
and get the speed up to 4k or so with two 6" carbon steel wheels made of
..012" wire, stacked-up. One trick is to stack-up a .012" and a .008" wheel.
Lean the piece to the coarse to clean and to the fine to polish.

An 80 (or maybe it's a 60 G) and 120 grit, white friable Norton wheel.

I use the grinder for rough shaping and renewing damaged edges on edge
tools before honing.

I turn, so I have an 80 grit aluminum oxide on the left for sharpening and a
50 carborundum (which came with the grinder) on the right for rough shaping.
I replaced the tables with workable ones and put a jig on the left. One of
the things I notice in a lot of shops is the lack of cleaning of grinding
wheels. Get a wheel dresser and use when the wheels glaze. It makes a lot of
difference. My set up is on my web page under sharpening.

So what do you like to have on your bench grinder and why?

Well, if I had room for two grinders, I'd have a 60 and a 100 grit
on one and a wire wheel and a buffing wheel on the other. As
it is, I have an 80 and a wire wheel, which has been a reasonable
compromise. I found a more rigid rest to swap out for the one
that was on it, which helps. So does occasional dressing with
a dressing stick (I like it better than a star dresser).

I probably use the wirewheel the most, usually for derusting and
deburring.

I also have a cheapie belt grinder, which also comes in handy,
but there are still some tasks I prefer using the wheel for, though
it is faster to change belts than wheels if you find you need to
change grits a lot...

General purpose bench grinders usually run at standard induction motor
speeds. 3600 rpm (actual speed usually listed as 3450 or
there about) for grinders up to 8", and 1800 (again, actual
1725 or 1750 rpm) for 10" & larger wheels.

There are also low speed grinders that use the 1800 rpm motor for the
8" and smaller wheels. These are better for sharpening since they
don't get the workpiece as hot, but naturally much slower at removing
metal and rough grinding. These slow speed grinders are best used with
wheels designed for them rather than the general purpose wheels used
on the standard speed grinders.

I wouldn't try anything bigger than a 6" wheel with a 1/6hp motor.

I've got two grinders. One has a medium wire wheel and a spiral sewn
cotton buff on it, for cleaning up and polishing metal, the other has a
medium and a fine Norton gray wheel on it for sharpening and shaping
metal. I've also got a coarse and an extra fine wheel for that grinder,
but I rarely mount them. I've got a general purpose basement metal and
wood shop, typical of a home hobbyist, with metal on one side and wood
on the other (mostly) to keep the machine oil off the wood. (I also
have TMT - since I've consolidated my Dad and my Granddad's shop into
mine over the years).

I hope it's not too late to return that motor. 1/6 hp is WAY too small
to run a grinder. What will happen is that the motor will bog down
when you try to remove more than the smallest amount of material. For
instance, sharpening a lawn mower blade would be totally impractical.
1/6 hp might be OK for sharpening kitchen knives, but not for removing
material. Removing material (shaping) is a very useful function for a
grinder, you should build yours with that in mind.

I have a 1/5 HP grinder, which I can only use for deburring.

Ok, thanks for the information. What minimum hp would you recommend
considering that I'd be using the grinder mostly for sharpening purposes and
other what I'd consider to be light duty uses?

I wouldn't have any problem returning the 1/6 hp motor, but the price was
right and I'm wondering what things I could use it for?

you can use it for sharpening small things, deburring, minor
beveling. I would keep the little one and also get a bigger one. You
can look for one in a used market. I am happy with a 1/5 HP (in my
basement) and a 1/2 HP (in my garage) grinders. 1/5 HP is useful to
remove metal around holes after drilling, etc.

1/2HP, 1750 RPM, minimum.

Some kind of a fan or other air handling device.

1. Don't limit your perspective by what you would be using it for now.
A grinder can be used more than you'd expect and you should build it
with a lot "head room" (room for expansion of your uses).

2. A wire wheel is useful on a grinder, but you tend to lean into it
more and you do need power for that.

3. I have 2 grinders, each is 1/3 hp. I could use more sometimes, but
1/3 hp is generally OK.

Ive three grinders bench mounted. An old Tombstone Craftsman, 1/3hp,
with a soft wheel on one side and a fine wire on the other, a 1 hp 10"
with a big rough wheel on one side and a course wide knotted wheel on
the other, and a 1/2 hp Souix with a white wheel on one side and a pink
on the other for roughing tooling. Or I use one of the 3 mounted belt
sanders....
