Sanding Blocks

Such a simple idea, yet it makes a world of difference in finishing. StewMac - feel free to copy this design, I've copied enough of yours!​

Sanding blocks are 1/8" neoprene foam (mousepad) glued over 1x2 & 1x3 scrap pine, with 1/4" roundovers ( makes 3/8" roundover with padding. ) Use waterproof contact cement. The large block is sized for 1/4 of a standard sheet of sandpaper, and will also take half of a 1/3 sheet piece. Small block works well for details, inside horns, etc. The neoprene grips the sandpaper exceedingly well, wet or dry, and has just the right amount of 'give' for very fine sanding.

Minor Ding Removal

Minor dings in bare wood can often be popped out by applying a bit of boiling water, which will swell the grain. If water doesn't work, try heated acetone. Place a small container of acetone in a large container of hot water to heat it, away from any ignition source. Steam will also work - to fix up large areas, use an iron on low over a damp towel. I have even gotten the hot water trick to work through a finish, but there is no telling what the result may be, and I don't recommend trying it.
