Red Green has demonstrated the bizarre behavior of belt sanders. That's not an exageration. It takes lots of practice to get the doggone things to behave. I hate my belt sander. There, I've said it. A civilized belt sander would be fixed on a tool where you could bring the wood to it, not some over torqued, wild west bucking bronk of a tool. Sometimes I've wanted to shoot the darn thing, but instead it sits, unused, in its corral, waiting to die for want of sawdust. Good riddance, I say. Instead, saddle up the ROS. Not that I have strong feelings about this.
The more I do, the less I accomplish.
