Inexpensive Sharpening Surface

Even though I’ve been woodworking on and off for a couple of years I still don’t have a set of sharpening stones. Of course I have one of those Arkansas whetstones where the grit difference on one side is probably 80 and the other side around 200.

I came across and article a while back where the author made a sharpening surface from sandpaper and floated glass. Instead of putting one grit on each side of the glass, I decided to allow for 3 different grits on each side.

Materials:

  • Adhesive that will bond to glass (I used Weldbond)
  • 9"x17" piece of glass
  • Up to 6 grits of waterproof sandpaper
  • Glass cleaner

I’m sure my piece of glass wasn’t floated glass, but for under $7 how could I complain? Total cost for this project was under $15 using 3 different grits of sandpaper.

First thing was to clean the glass.

The sandpaper sheets were halved and torn by hand. These will eventually get scraped off the glass when they become no good anymore so I’m not concerned with nice edges.

Glue was applied and spread on the backs of the sandpaper pieces that would be adhered to the glass.

Finally after gluing the sheets on to both sides of the glass, weight was added to the top to make sure the sandpaper didn’t curl on its edges while it dried.
