Default bench/pedestal grinder advice

Hobbyist trying to expand my shop. I am looking for a strong bench grinder to work on 1/4 inch plate steel pieces. I am wearing out too many flap discs on my angle grinder. Any suggestions on a bench grinder with "industrial" capability? I have read about Balco and 8 or 10 inch wheels that works off of 115 volts. What do you advise? This forum has always given me good advice. I appreciate your thoughts.
Bruce

You did not say how much material you need to grind off.

The things I look for is hp, tool rests and guard, a light would be nice.

You want a strong tool rest which means sheet-metal guards that hold the rests are out.

This grinder does not look bad.

Look on Craigs List or EBay for a Baldor 8" or larger grinder. I found one using Search Tempest that was for sale on the Boston CL site for only $100. I paid the seller an extra $100 to have him take it to the UPS store and ship it to me in KY. Even at $200 it was a steal as the grinder was brand new.

Another option would be an old, emphasis on old, Sears/Craftsman industrial grade grinder. Probably have to be 20 years old or better to be worth your time and effort.

As GWIZ said sheet metal guards are a sure indicator of a cheap grinder. Look for a cast iron tool rest and wheel guards.

Here's one place to look: http://hgrinc.com/ and another is http://www.lostcreekmachine.com/ (metro Chicago).

Good hunting.

Sounds to me like you are sanding when you should be grinding. Why use a flap disk on 1/4 inch plate?

What I have told all the yunguns I have worked with that a bench grinder is for sharping drill bits and other cutting tools, not for grinding plate unless you have a 10" or larger. Even with one that size i would never use it. If you have to do a lot of grinding chances are you are not getting a clean cut with what ever you are using and a weldment should hardly ever have to be ground. Grinders are for mistakes and general clean up and weld prep. Also I never use flap disks. IMHO

It's been my experience that they're faster. I've got two bench grinders, like digr says, they never get used. I've pretty well switched completely to belt-type grinders/sanders. They're fast, easy to use, and the belts last longer than a flap disc. Does the same job though on parts you can hold in your hands.

Buy or build a belt grinder & change your life 100% for the better.

This one is missing the Guard and one rest unlikely too find replacements.
Looks like this second one did not last long also just deleted.

Default appreciate the feedback

Thanks very much. I looked up the used machine sites--great machines but I would not know how to repair/install parts. The craigslist site has been taken down by the poster but I will try with tempest later... I did not even think about a belt sander for grinding metal--I will research that as well. If any other thoughts/suggestions come up--please let me know.
