 Much better than the reviews said February 24, 2006

I was a little hesitant to buy the Delta after I read the reviews but I really needed a way to sharpen my lathe tools. I did a lot of research comparing the Delta to the Tormek and in the end bought the Delta. My reasoning being I couldn't afford the Tormek and all of the accessories to go with it and the two systems "spec out" about the same.
I am a complete novice when it comes to sharpening but I am able to sharpen all of my tools on the Delta with out difficulty. Here are my thoughts: 1 Yes the 23-700 is a great idea for a tool but it is built a little "cheesy". 2. As far as sharpening speed it is just slightly slower than the Tormek based on RPM 70 vs. 90. No big deal. 3. The small wheel is not intended to "rough sharpen" lathe tools or anything other than drill bits etc. You just don't put a good tool on a 3450 RPM wheel. The tool rest does just what it's supposed to do. This should not be an issue. 4. The large wheel is soft and I do have to dress it often but I don't ever over heat my tools. 5. The wheel does wobble just like all the reviewers have said. Delta really missed this one.
The bottom line is, I am able to put a razor sharp edge on my 10 tools in about an hour. This tool has been much better than expected. (I have considered buying the Tormek adapter for the 23-700 but so far I haven't needed to.)
 A rare bad outing from Delta February 8, 2006

This has been a disappointment from day one. Take a look at my other reviews and you'll see that I'm a straight shooter, and only too happy to give praise when warranted. Here, however, the right rating is one star. The comment about the rests being unsuitable for lathe tools is precisely right. Worse, the one on wheel wobbling is spot on, too.
The stone that came with my unit had a "hard spot" that wouldn't true no matter how much I tried to dress it out. Eventually my dressing stone "caught," and there was an ugly "snap." I opened the unit up and was amazed to find that the main wheel was splined onto a nylon gear. Instead of engineering a steel gear with a shear pin to take an overstress, Delta went with a cheap nylon gear. Mine was in pieces, all over the gearbox.
I won't waste the cash to repair it, and I'm not kidding.
It's been weeks since I endured this, so this isn't a hot-headed review. I am, frankly, amazed that Delta let this piece of junk have their name on it.
If this is what Delta is becoming now that B&D has them, I'm concerned.
Delta 23-700 grinder review July 23, 2005
12 out of 12 found this review helpful
This grinder is a very good design and configuration for tool edge preparation. It lends itself to a good rough out then polish of the tool edge.
The flexibility of the large wheel tool rest is excellent. The overall design eliminates all vibration, and runs smoothly.
However two main points of the operation are very lacking.
First the 6 inch wheel rest does not accomodate itself to the angles of lathe tools. Attempting to adjust this rest to more than 15 degrees is not possible because the rest design and attachment point prevent this.
Modifying this attachment by adding spacers to provide clearance will allow securing angles needed. Once this is done though, your rest will be too far away from the wheel. You will then have to add an additional plate to the rest that extends closer to the wheel.
The second detriment, is the speed of the large polishing wheel. The speed this wheel turns is too slow. It is very difficult to hold or guide a tool with an irregular edge across this wheel at the perfect angle without gouging a channel into the large wheel.
Gouges appear almost instantly, and then attempting to dress the wheel to repair these gouges takes way too much time because of the slow speed it turns. Extreme pressure is needed to grind the wheel true. This one aspect, trueing the large wheel, takes many minutes with the best of diamond dressing tools.
It will take considerable practice to use the polishing stone effectively, and the use of this wheel will consume many minutes of your time to use. Time you should be using to use the tool you just sharpened.
If I can recommend to the engineers how to improve this grinder I would suggest to:
Redesign the 6" wheel tool rest to incorporate greater flexibility of angle configuration.
Redesign the polishing wheel gear reduction to increase the rpm's of this wheel to 500 rpm.
If this were done, this would be the perfect tool sharpening grinder value available.

A disappointment from Delta April 29, 2005
11 out of 11 found this review helpful
I loosing faith in delta slowly but it is happening. this grinder looked and sounded OK for my purposes. But the slow wheel wobbles side to side so much it is not worth the aggravation. I tried Truing it, Shimming it and reversing the wheel. All to no effail. upon Reversing the wheel I noticed that the wheel shaft is machined to small creating the wobble. there is nothing that can be done. I am disappointed in delta For this design
 Works exactly as advertised. September 30, 2002

When this unit is used properly, dry wheel for grinding and wet wheel for honing, this tool does a more than adequate job. When honing, using the entire wheel by sliding the blade across the surface using using moderate to moderately strong, even pressure eliminates the need for frequent dressing. Cleaning could be easier and the guide could stand some improvement, but overall this is a very good tool, especially considering the price. I got what I paid for.
