Bench Top Grinder

[BigK600]

My Dad wants this knife sharpening system from Dunn Knifes. I was thinking that I should just get the wheels and buffing compound. They don't have the set up with Black and Decker ginder anymore. http://http://www.dunnknives.com/services/sharpening.php

He needs a Bench Top grinder for this set up. What are some good ones. I think a 8 inch would be nice. Variable speed might be nice. Dont really want to spend a ton less than 100 bucks. I'm looking for suggestions for some people that have used one, what are some good features to have what are things you dont need? How powerful of a motor do you need? Other Tips?

Heres the ones I'm looking at:

Delta GR450 seems really nice but kinda more than I wanted to spend,

Hi BigK.

Many ******** knife aficionados don't like powered knife sharpening solutions (and a few do). There's an ongoing argument that it fries (= takes the temper out of) the fragile edge of the blade. You know how quickly a little friction can get a thin piece of steel very hot. It's an ongoing debate, but I agree with the manual grind crowd, your best edges come from handwork, not a buffer. PLUS a good manual jig allows you to put the edge on precisely, whereas handholding on a buff allows angles to vary (unless you have a good jig). But that's my opinion, and the opinion of many other knife afi's.

But that will probably not disuade you or your father. So, in that case, you would want to look at either a SLOW SPEED dry buffing/sharpening system, or a waterborne stone system. If you decide to go with the slow speed buff system, then look for RPM speeds of 1500, 1000, or less. Don't let that edge get hot.

And remember, I'd argue you can get a better edge, with a lot less hassle, and less cost, and less danger (of an edge catching and the blade being thrown across your shop) without a powered system. I have a nice slow speed Baldor buff and it is not allowed near my edges.

PS: What do Dunn Knives mean when they say that their system will sharpen "both stainless and 440V?" 440V is stainless...

Ok thanks. I found this little set up the other day.

http://woodworking.jettools.com/Products.aspx?Part=708015&cat=333164

Ok this is made by JET looks like the best thing out the for sharpening. Its more then I want to spend. And the water would freeze in the winter out in the pole barn.

I think I'm going with the Delta 8" Grinder or would a buffer be better?

Also just found this Delta set up: http://www.deltaportercable.com/Products/ProductDetail.aspx?ProductID=11473#

How well do one of those work?

High speed grinders are the worst way to sharpen tools and knives.

The best powered sharpener is the Tormek system. It consistently wins the comparison tests in the woodworking magazines. It's kinda expensive. I'd love to have one someday. I sharpen all my chisels, planer blades, and knives by hand. I like diamond stones for this, but I've also put an awesome edge on tools with a selection of wet/dry sandpaper and a piece of granite floor tile or 1/4" plate glass. It's called the "Scary Sharp System". Heres the link to the Tormek system:

Yeah I've read reviews on the Tormek system looks good...to much money. There a place up here that has the JET system for 260 on sale. My dad isnt a woodworker, just has alot of knifes for hunting and fishing, and axes.

I guess we already got the dunn kinfe set up coming in the mail just need something to power it.
