Variable speed a minus? March 17, 2008
The Engineer
OK, I own the twin to this unit, a Steel City grinder without the quick change feature, but what I find is that it is difficult to balance the wheels for different speeds. Yes, I can balance them nicely for slow speeds, but then they spin with a different harmonic at high speeds. And when the wheels are not balanced, the light bulbs blow out immediately. I gave up on the light. As with most grinders, the tool rests are virtually useless. Try setting these up to grind a proper angle on a chisel. I'll rework these or make my own. I'd like to hear from others on the quality of wheels these days. These Chinese jewels that came with the unit were out of round and out of true every which way. Are Nortons better?

Too Much Vibration of Plastic Shields February 7, 2008
Jack F. Olivieri
The grinder seems stable at low, med and high speeds without the eye protective plastic shields. When the shields are installed (A NECESSITY), they vibrate very badly, making a loud noise. The shields are not secured well enough to the grinder. As a result, at high speed the vibrate as much as 1/2 inch or more! This puppy is going back..

Quality Concern October 1, 2007

The packaging was good as the box was unpacked. From there, it progressively got worse. The brackets to hold the clear shields on do not offer adequate fit. The bracket to hold the tool rest is finished for a left hand application. Once again fit & finish is not a concern at Delta. When I turned the machine on, It almost vibrated off the bench. I turned the variable speed up to see if it would make a difference and in doing so, it stayed on full throttle. The knob is totally inoperable and does nothing. The Wheels could not be trued using the supplied stone dresser. Looks like they will have to be replaced with better quality. Delta support line is closed tonight. Hopefully they will support this mess of a machine!!

My husband does woodturning and needs this tool for sharpening his tools at a lower speed. He's very pleased with the quality.

I also own a Delta 23-725 which is a much better machine, but this one isn't all bad. I use this one for grinding, and the more powerful 23-725 for wire brushes. As mentioned in anther review, the stone quality is poor, they have to be trued up. The 23-725 probably won't come with any better stones, but it is a much better machine. The variable speed on the GR450 really serves no purpose, and no grinder should turn over 1800 RPM. In my humble opinion the GR450 is a 6" machine with 8" wheels stuck on it. It you don't need a lot of power, and you have some strange need for the variable speed go for it; if you want a great grinder get the 23-725. I should also mention I've had my 23-725 for six years; if they've changed it I wouldn't know about that.
