Topic tags/keywords: tip question jig trick

Advice needed: I replaced the buffing wheels on my buffer with MDF discs that I profile and use for honing the inside bevel on my carving tools. I would like to add two extra wheels: one on the right and one on the left, that I have shaped for honing different carving tools. It’s only a 1/2 inch arbor, so I am hesitant to add arbor extensions to each side. If it was 5/8 inch there would be more stability for that. However, there is an awful lot of wasted space on each side of the buffer because it has very long arbors. I have no idea how I could add the extra wheels on this wasted arbor space, because I cannot see how I would lock the wheels in. I am not a machinist, but wondered if there is some easy way to do this.

My buffer is the Central Machinery 6 inch model: https://www.harborfreight.com/6-inch-buffer-94393.html

You can see that there is easily room for extra wheels on either side of the buffer.

Thanks!

Well Bill its a problem I have also wondered, I ended up just adding undersized MDF “shims” between the buffing wheels, there is no reason why if you had a lathe you could not turn up some specific spacers and you are set.

I do not have a lathe so I just holesawed the MDF to a size less than the buffing pad should work just the same for MDF, in fact you could glue the collars on and make it one piece.

This may help….pitty I cannot buy a polisher for $44 in Aust !! otherwise I would just set up a couple.

BTW what actually goes on in a Tree Farm? ..apart from the obvious growing trees and apart from a forrest or nursery what did you do with them?

While this sort of thing may not stop the
wheels from spinning on the shaft, they will
restrict horizontal travel.

Loren, Yes, this is something I found as well, and it would certainly be part of the equation, preventing lateral movement of the wheels. Another part of the equation seems to be the flanges that stabilize the wheels, which are also available on Ebay and Amazon. The only problem now is how to keep the MDF wheels fixed to the 1/2 inch arbor? Some sort of flange that could screw down onto the arbor and also fasten or screw onto the wheel would probably do the trick, but I’m not sure if this sort of thing is made. I wonder if I just drilled a slightly smaller hole than the arbor diameter and forced the wheel on would be enough to hold it tight? Maybe some epoxy as well would do the trick?

Rob, thanks for the reply. I am not clear what you mean by these “shims” though.

The tree farm we also call a ‘tree nursery’. My dad sold nursery stock in at our home in Malvern, PA: trees and plants use for landscaping around homes and businesses. My mom headed up the greenhouses and flowers which were a big part of the business. I worked there since I was a teen, and worked on the landscape crew for many years before and after college. Hoeing fields and digging trees by hand is amazingly hard physical work. It’s where I learned what hard work really is!

Bill the reference to shims relates to the space between each each wheel.
For example A honing wheel the a spacer/shim then another honing wheel, etc then the nut.

Tree farm. Got it. Its what we refer to in Aust as a forrest or Nursery.

Many years ago I worked at an HF antenna farm it was over a huge area and also a lot of work maintaining them but never saw any growth of new antennas!!
