re: Drum sander issue

GeorgeWest- I will double check the wrapping.  I struggle with getting it all lined up, but cannot remember when this issue started (before or after I changed the paper).  

Splintergroup- I'll try measuring as you suggest.  I don't think this board even was on the in/outfeed extension, but maybe.  I can hear a difference in the sanding so something is "catching" and then levels out.  

Thank you!
