I was in the market for a drum sander a while ago as the small one I built wasn’t able to do the larger pieces I needed. I scored a great craigslist find on an older Performax 16/32 that was sitting in this nice old man’s garage. The only thing it needed was a new conveyor belt.
Anyways, I’ve made all the adjustments and leveled the drum, but I’m running into a minor problem that is driving me crazy. I can run a cutting board through, say a 15×11” board. Using 80 grit with light passes, the sander takes more out of the center of the boards than the ends. It’s not much, about a 1/16”, but to me it’s noticeable. My wife says I’m crazy. I just ran one through to clean it up and at the front and back, both left and right sides are about 1.250”, but in the center of the board, it’s about 1.200. Call me OCD, but I’d like to try to get it closer. I’ve tried angling the wood, as well as adjusting the speed. I’m just not sure what adjustment on the drum to make. Could it be the tension rollers? Has anyone had any problems like this? I looked in the manual but didn’t see anything that related to the center being low, just sniping of the ends.
