I have a relatively new Accura 25" dual drum sander and I have not had the greatest luck setting the drum height...my latest attempt, after following the owner's manual and talking to the place I bought it, gave me some pretty significant burned-in racing stripes on a practice piece of white oak. I am using 150-grit on the front drum and 180-grit on the rear drum. I also used a rotcator to set the drum hieght, and I know I have plenty of suction to remove the debris. I am pretty sure that this is a case of operator error.
Can anyone give me any advice, tricks or helpful hints on how to set the height on the rear drum?
Thanks!
