Crafstman Model 315 Belt Sander
Tool: Craftsman Model 315 11720 – 3″ X 21″ Belt Sander
A relic from the days of quality tools by Craftsman. Do they even make tools still? When I started woodworking a Craftsman saw was the kind to have. I owned a Crafstman Radial Arm saw but it was too much to move East. I picked up this used Craftsman belt sander when a Sears in San Francisco closed it’s doors and auctioned the entire store.

because it still works.
Experience:
I had a great Bosch belt sander when I picked this one up so I put this Craftsman Belt Sander to work on the worst tasks. 40-grit belts to remove huge amounts of material, anything dirty, tough or likely to hurt my super-nice Bosch I saved for this crappy unit.
But crappy this Craftsman is not and I soon realized that with a fine grit belt I could get the perfect concave on chisel and plane blades before moving to a sharpening stone. There is something about the metal wheel and the access to the belt that allows me to grind blades by hand with impressive results on this machine that I cannot do with other belt sanders.
Comments:
Like I said, This belt sander was well-used by 1990. I had a Bosch sander which, after getting this Craftsman, I reserved for woodwork, relegating the Craftsman to heavy sanding.. and you know what? The Bosch died, my Porter-Cable died and this ugly used Craftsman tool is still sanding.
I use a screwdriver to wedge the wheel open to change belts but it still adjusts perfectly, runs smoothly, and sands like a good belt sander should.

Most popular belt sander on Amazon.com, the Bosch 1274DVS ironically the same model this Craftsman long outlasted.

hi i i got one in a yard sale but i can not put the belt can you more details , of how to change belt please thanks
Hello, I’m not sure how you are ‘supposed’ to do it…. but I stick a large screwdriver in front of the front wheel and pry the wheel backward. It locks into place. I change the belt and then I hit it with a hammer or pry it forward. LOL, I know… but I’ve been doing this for 20 years and it still works just fine. In fact, this is my longest lasting and best working belt sander today. Sorry, never looked into how to do this the right way…

You had someone write in asking how to change the belt on a sears 315-11720 sander. It is the same as the 315-11721 and here is a manual site.
