I don't mind using up electrons when needed, but I do have to pull out my corded random orbital sander to finish the job a bit, then clean up the sawdust and wrap the cord before having to put it all away after three minutes be a bit difficult. I now have two hand-powered sanding blocks that use the same Velcro sanding pads and can keep my most-used abrasives handy and return them immediately after use. I can put a wired grinder in the attic.
