Change a grinder into a buffer. Convert a Hercules variable speed grinder into a variable speed buffer. Step-by-step instructions and its use are demonstrated.
2000 to 3400 RPM, 1750 rpm is the normal slow speed buffer rpm but 2000 would be just fine, good work. Remember slow speed for soft metals and high speed for hard metals. Make sure your buffing wheels are rated for the higher rpm. They also make extensions for grinders buffer conversions that move the buffing wheel away from the motor and give you more room for your work piece. Thanks for sharing
Thank you, Taz man Great comment. The only issue with the extensions is that they need to be perfectly in line. Otherwise they create a terrible wobble which can be very problematic. I don’t think there’s a need for an extension in this application and I agree that the proper buffing wheels are important, especially at high speed. Thanks again consider subscribing Joe.
Thanks for the vid. Only issue I saw was that you moved the workpiece from the coarse wheel to the fine wheel without cleaning it first, thus contaminating the fine wheel with coarse polishing compound.
You have a valid point. Thank you for your comment. Yes to be sure that you not contaminating 90 fighter grit be certain that there is in any of the course grit on your material. Consider subscribing. Thanks Joe
Thanks for the video. I just purchased this and was wondering about adding a buffing wheel to it. Would adding a wire wheel work as a well? If so do you need to add a spacer for it as it doesn't seem like you added a spacer for the buffing wheel. This model didn't seem to come with a spacer.
Thank you for your comment. The need for a spacer is always depended on the width of the buffing wheel or wire wheel you are placing. If you put a Buffing wheel the same sickness or width as the grainy will you were removing you do not need a spacer. If you put one on that’s more narrow you to do. Take care joe
i have bench grinder and i remove the stone wheel and put MDF wheel that has already covered with silicon carbide powder for sharpening knives....when i turn it on , there was a strange sound comes from the mdf wheel when i get the blade near of it as an air pressure sound, then, a strong explosion sound happened....but without damaging the grinder... what was that!!! it happened a couple times...
Hello Cheryl Howard Thank you for your question. Sometimes that inner space or flange requires a little work to get it off. A gear puller works great but also a large plier opened up and then tapped can push that off. Consider subscribing. Thank you - Joe.
Dr Joe would you share the information & where to purchase the wheels and compound you acquired for the conversion? Did you order it from somewhere like Amazon? My local Lowes or Home Depot doesn't carry much other than stones and wire brushes. I have an extra old 6" grinder want to order exactly what you are using. Thanks for the video!
Hello, thank you for your comment and question. No Home Depot or Lowe’s are not gonna have what’s needed for the buffer. I went on Amazon and look for the type of buffing wheels that I wanted as well as the buffing compound. I will try to put a link for these in the description within the next few days. Good luck with your conversion. It will work fine. Take care consider subscribing Joe.
I bought the grinder at Harbor freight and I believe I bought the buffing wheels there also. The buffing compound I purchased on Amazon. Thank you for your question. Consider subscribing. Thanks, Joe.
Thank you for your question. I believe the reason that people use the threaded cones is to change buffer wheels frequently. This set up I think is very useful and it’s the one that I prefer. Consider subscribing. Thanks. Joe.
Hello sledge. I should have put the link in the description. Sorry about that. Here it is for you.

Hello Damien! Excellent question. You can leave one side buffer in one side grinder without any problems. Think about it, we always are using a tool on one side or the other, so it will not harm the motor. Consider subscribing. Thanks, Joe.
Hey there thank you for your question. I purchased the buffer pads on Amazon, but they’re readily available at many other places such as tool supply stores. A soft one and a firm one is a good combination. Consider subscribing. Thanks, Joe.
Good question. Sometimes a polishing machine have an arbor that’s longer than a grinder so that the wheels are further away from the body or the motor. This allows larger items to be manipulated around the buffing wheels or polishing wheels. That’s the make up of a classic buffer.
Hello Bruno, thanks for your comment. I don’t fully understand because I was able to get buffing wheels on mine because they’re the same thickness as the grinding wheels and the large washers and nuts went on those just fine. Subscribing. Thanks, Joe.
Hello there. Yes I went back and reviewed that and I understand your concern. I was looking away when I was buffing that cap. Yeah it could’ve been dangerous for sure. Consider subscribing. Thanks. Joe.

Yes a Grinder should be able to be converted to Buffer good work

Hi Dr. Joe, did you get your grinder, buffing wheels and compounds at Harbor Freight? Hercules is a good brand.
I bought the grinder at Harbor freight and I believe I bought the buffing wheels there also. The buffing compound I purchased on Amazon. Thank you for your question. Consider subscribing. Thanks, Joe.
Great video. How come people are using these long threaded cone like screw attachments and just screw the polishing wheel onto them. I am confused.

Could you provide links for the buffing wheels you used in this video?

What’s the difference between a grinding machine and a polish machine? Are they the same machine?
Good question. Sometimes a polishing machine have an arbor that’s longer than a grinder so that the wheels are further away from the body or the motor. This allows larger items to be manipulated around the buffing wheels or polishing wheels. That’s the make up of a classic buffer.
This would only work if you have a long shaft or threads the nut is left out on mine
