This sander cranked on like smooth and worked wonderful. I came across this one, which has met all of my needs. I find this one to be a vast improvement over the Rockwell. It could just be that some bolts are lose, but I'm not sure. It's sander that you have to apply a lot of hand pressure to.

"There's a lot of thick metal here!"
This is very similar to my old one with a few differences. After it lost the roughness I bought 3x18 belts from Walmart. I did it in my yard to i don't really care about dust. Also take a short break every 15 minutes to let belt cool off. It's sander that you have to apply a lot of hand pressure to.
