I happened to stumble across the Spider Sander and instantly it was one of those “well, of course” moments. This is a great idea – adapting existing supplies to a new application. This sander head can loaded for aggressive material removal or for fine finish sanding. I like the swept area and with the floating loops it should smooth surfaces in a very natural way. I haven’t yet located a place to buy a Spider Sander but, in time, they will be here.
