Notes on tools:
Online reviews can help flesh out the tools dedicated pages, after checking with people currently using the tools to find out drawbacks and good qualities. Here's a review of the Central Machinery Oscillating Spindle Sander: [] This seems to be the manufacturer's description since it was on both Amazon and Pricegrabber: "This oscillating spindle sander features a sanding spindle that moves at 58 oscillations per minute with a 5/8" stroke, for faster material removal! The design of this oscillating spindle sander helps you sand curved and contoured surfaces on your work piece that would be difficult to accomplish with a hand or orbital sander. Includes (5) rubber sanding spindles, (6) sanding sleeves, (6) table inserts and (4) spindle washers."
Here's a product description of the Ridgid Oscillating Edge Belt Spindle Sander EB4424 at Home Depot []: "Constructed as 2 tools in 1, the RIDGID Oscillating Edge/Belt Spindle Sander operates with rotary and oscillating motion to help you easily and quickly achieve burn-free finishes on edges, contours, faces, inside curves and outside curves. The tool-free conversion from belt to spindle helps you quickly and easily make changes, so you can complete multiple jobs quickly and easily, and the onboard accessory storage neatly holds the belt mechanism, washers and more to help your work area stay neat.
