I noticed that the most recent AWW Journal pictures a 3" pneumatic orbital sander on page 64. My smallest orbital sander is electrically powered and 5". It's really too big for most of the work I do. Does anyone have any recommendations re: a good mini orbital sander (powered in any manner) to use for small (4" to 10") bowls and similar small work? Has anyone tried the new Dremel 1100-01 Stylusâ„¢ Cordless Rotary Tool as either a sanding tool or carving tool?
