Can You Put a Buffing Wheel On a Bench Grinder

As you can see, it is possible to put a buffering wheel on a bench grinder. The process is not that difficult and any handyman can do it in a few minutes. Yet there are some more things you need to know before you make the switch.

First, there may be a reverse thread on the side of the bench grinder you want to place the buffering wheel. If there is, you will want to watch how you thread the wheel and the bolt.

Second, after placing the buffering wheel on the bench grinder, you may find that you do not have the space needed to polish all the angles on your project. You can add a second wheel, an arbor extender or spacer to help you get that room.

Third, 8” wheels are better than 6” ones although the latter can work well. You just need to watch how hard you press.

Fourth, all motors are not the same and if you press too hard then your wheel will get slowed down and not do a great job. A variable speed bench press may give you the power to avoid this issue.

How to Convert Bench Grinder to Buffer

Converting a bench grinder to be a buffer is not as simple as changing the wheels. This takes a little time and a little ingenuity to make sure you get the parts to fit and work properly.

Here is one way to make the conversion in your own workshop:

  • Bolt the grinder down to your work bench or a solid piece of wood. This helps provide you with stability you need as you work.
  • Next, you remove the wheels, protective wheel guards and any other unnecessary part. You do this till you are down to the motor and the axles.
  • ​You may need to cut the axle to size which means you take a hacksaw with a strong blade and cut down the axle. This is easy if you turn the grinder motor on and place the hacksaw blade on the moving axle. Let the axle do the work.
  • ​After you let the axle cool, just slip the buffering wheels spindle over the axle and screw it on nice and tight.
  • ​Now the other axle on the other side of the bench grinder may be too thick to quickly attach a spindle. In this case you take a hard tip for a lathe chisel and place it in a pair of vise grips.
  • ​Turn on the motor and place the hard tip next to the spinning axle.
  • ​Take your time and carefully use the hard tip to remove the extra thickness on the grinder’s axle. Just remember to remove just enough thickness to fit the spindle on securely.
  • After the axle has cooled, add the spindle and screw it into place.

Now you have to buffering wheels to make your polishing life a lot easier
