The cost is low and the materials are easy to come by. The material the wheel is made from is mat board. Yes, it is the mat board you find at art supply stores and framing shops. You adhere layers of it together with a PVA glue such as Elmers. Be sure you cut accurate circles so you don't have to spend a lot of time shaping it into a true circular surface after you mount it to a motor. I did the final shaping of my wheel with a coarse grit sanding block while the motor was spinning the wheel. The sanding to a true circle creates a lot of fine dust so I used a vacuum cleaner nozzle right next to my sanding area to collect the dust. Don't forget to wear a dust mask! After the wheel is trued you can put honing compound on it.
I used 8 layers of double thick mat board in this wheel. I put weights on the stack of mat board disk while the glue set to prevent voids in the layers. Getting voids is a defect that will spoil the effectiveness of the wheel.
I have glued my new stropping wheel onto a plywood disk screwed to a faceplate so I could spin it with my lathe. It is very important to look at the photo above to see how the wheel should be turning in relationship to the tools you are sharpening. I am standing on the backside of my lathe while I am sharpening my carving tools to get the correct spin direction.
What a difference using this wheel is making in my work. I can't get my carving tools this sharp with hand stropping on leather. The tools now glide through the cuts with little effort or pressure leaving a nicely polished surface. I hear that lovely ssssstt noise as the tools cut. The noise that only happens when you have razor sharp cutting edges with polished bevels.
