I use a 6" grinder w/ the Wolverine to grind my gouges. Recently, I
have heard some comments relative to 8" being better. Can someone
explain the specific advantages of getting the 8"? Second, is there a
reason to go with something more expensive like a Baldor or is a grinder
like the Jet 8" good enough?

Thanks all

I like the 6" as it makes a more prounounced concave bevel

the 8" is too expensive for the little benefit - whatever that is

a cheapo Ebay grinder is just fine - make sure the wheels run true!

George--

I've split the difference -- I use a 7" Baldor which I bought for around $200.00. I also use
the Oneway balancing rig. Before that I had a cheap import 8" grinder with 7" wheels.

The Baldor properly balanced is a pleasure to use. It is quiet, smooth,... I grind pretty
frequently and sometimes when I go back to it, I find it is still spinning down.

This grinder has a 5/8" shaft and many of the imports use a 1/2" shaft. Is this a factor? I
don't know. Are better bearings a factor? Don't know. But it sure runs sweetly.

Woodcraft has an excellent 8" slow speed (1700rpm) grinder for around
$100.00. I've owned one for several years and I have been very satisfied
with it. Runs very smooth and true with little or no vibration. Mine is
not even bolted down.

You do want the slower speed for grinding and I don't think slower than
3600rpm is available in 6" grinders. If you plan on being around
forever, you may want the Baldor. Otherwise a good quality 8", 1700rpm
grinder is fine.

Can't comment on the Jet, as I don't know anyone whe owns one.

It'll pull 25" of grit over the tool in the time it takes the 6" to pull 19.
Other than that, and price, I'm stumped. I seriously doubt the
oft-mentioned concavity is discernable over the 1/4" or so of bevel, not
that it makes a difference, anyway. The concavity is for ease of
resharpening. The way the tool is used, it makes no difference.

There are a couple that I know of. Sears has a variable speed 6" for 70
bucks that goes down to 2000 RPM, which gives a slightly lower surface
speed than an 8" at 1750,
@ & vertical=TOOL&pid=00921152000&subcat=Bench+Grinder s
and Delta has a similar model
http://www.deltawoodworking.com/index.asp?e=136&p=848 which normally
costs about the same but is currently on sale for some absurdly low price
at Lowes Delta clearance, if you can find one in stock--ignore the prices
on the Web site--they're still showing the Delta midi lathe at twice what I
paid for it.

Of the two, the Delta is the better deal simply because it comes with fine
and coarse wheels and it the fine one is white, while the Sears comes with
a fine gray wheel and a wire brush. Add the Lowes sale price on top of
that and it's pretty hard to beat.

If you plan on being around
forever, you may want the Baldor. Otherwise a good quality 8", 1700rpm
grinder is fine.

Get a Tormec. Makes all others pale in comparison. Doesn't ruin the temper
and once I have the tools sharpened, successive sharpening takes about 5
minutes. I now turn with only razor sharp tools. Spoilled, I guess.

Wet wheels still have the same maintenance problems as with dry grinders.
e.g.: wheel need dressing and truing etc. and the wheel will need replacing
every so often. Many woodturners have badly shaped tools or have bought new
tools that need re-shaping, in this case the wet wheels will take
considerable time to create the new edge, and also cause a lot of valuable
wheel wastage.

Not everyone can justify the expense of the wet system and all the jigs. A
good dry grinder will work extremely well and when you have honed the tool
after grinding, the edge will be just as good as any wet wheel. As for
ruining the temper: HSS will not lose the temper below red hot, but I
advocate frequent dipping of the tool into water (with a little soluble oil
to stop corrosion) to keep the heat down below 200 deg C or touch heat.
