How fast should my Velcro backed sanding disc be spinning?
There aren’t that many choices – fast spinning disc and slow spinning disc, fast spinning wood, slow spinning wood, and no-spinning wood. They all sand the wood. If the adhesive on the sanding pad melts, we are spinning it too fast. If we are hand sanding and burn our fingers, we are spinning the wood too fast. If we burn the wood, we are definitely spinning it too fast. I sand with a slow spinning disc and stationary or slow spinning wood.
