Rotary four wheel attachment for 2"x72" belt sander/grinder

[garycullen]

I made a rotary 4 wheel turret for my 2" x 72" belt grinder. It uses 3",4" 6" and 8" x 2" wide wheels. Instead of 4 separate arms for each wheel it uses only ONE ARM!. It is 6-1/2" wide and the pivot is in the exact center and all 4 wheels are the same distance from the edge of the pivot arms. I set the distance for each wheel using a telescoping gauge. When you change to a different roller the belt lines up exactly. I didnt even have to adjust the tracking for any of the rollers whether on one side or pivoted to the other side. I also made the pivot on the side arms offset, so when you go from one roller to the other you don't have to adjust the arm a lot to tighten the belt.
