I have a pre Grizzly 6"x48" belt/12" disc 2hp combo sander that I have had for years. I have always taken the large belt off when done with a project to keep it from stretching, I guess. Kind of like detensioning a BS blade. I am now doing more woodworking now that I have fully retired and its a real pain to keep having to unscrew the side and take off and on the belt now that I use it more. What do you all do? Will it hurt to just leave it on tensioned? Maybe the worse case is that it will stretch the belt and it fails some day? Randy
