for the first time since i've owned it (lotta time, but very little use until now), i've needed to swap out the sanding strip on the drum sander. the left side went pretty much ok, but when it came to the right side, it was, as they say, a whole 'nother smoke. hard as all get out, and needed pop's extra hands. now i know something like this shouldn't be this much fun. any opinions on what i'm doing wrong?
