Hello. I’m in the market for a bench grinder and am wondering what advantages if any would an 8 inch grinder have over a 6 inch?
I will be using it for sharpening lathe gouges a lot as well as restoring other old chisels and some metal shaping.

Any thoughts or ideas would be appreciated.

The 8” gives a lower hollow grind, so its a stronger edge. Get a slow speed for sharpening.

I concur with Don.
An 8” is better than a 6” in every meaningful way.

Kind of what i was thinking but is it that much of a difference that it would be noticeable?

I was looking at the Porter Cable vari speed grinders. lowest rpm is 2000.

Yes I would definiately recommend the 8” Grinder. 8” is has way more power than a 6”. I have a review of a Porter Cable 8” Grinder, with a video. http://lumberjocks.com/reviews/3058 Check it out. Its been a good grinder for me. I know the reviews arn’t the best, buts its been great for me.

Lot of folks recommend this grinder because comes with white friable wheeks. If live near a Woodcraft store might be worth a look. If can make an instore purchase without lot of time fine.

Feel same way about in store purchase of Porter Cable, or other brand grinder. Never know today if going to get a good grinder until out of the box and running. If all grinder needs is wheels trued okay, if other problems take it back for exchange or refund. No matter where or what grinder buy get a diamond wheel dresser at same time.

For friable AL wheels shop sales.

I do not care if grinder rpm is slow or fast either will blue your tools if do not know what you are doing. Been using a 6”, 3400 RPM, 1/3 HP grinder for almost twenty years to sharpen my lathe tools. Until that grinder dies not in the market for a grinder. I would like an 8” grinder because most come with 1” wide wheels. Think Harbor Freight 8” grinder come with ¾” wide wheels, not sure why.

I have a Palmgren variable speed and am very happy with it. Bought it from Sears website.

I have the wet / dry from Harbor frieght. Has a 6 inch dry wheel and a 10 (?) wet wheel. It does a surprisingly good job for me.

I’ve got a hand crank 6” grinder. Works for me. Infinitely variable speed :-)

I have the 6” PC bought a number of years ago. OK for 6”, wish I had an 8”. Had the HF hoosier talks about, sold it at my garage sale.

Also, the latest 8” PC variable speed units are shipping with standard medium blue wheels, not the better white friable wheels they used to put on one side.
