[Elecraft] Black Widow Paddle

[Jeremiah McCarthy]

I wonder if using a power sander, which has a soft rubber backing pad, will cause rounding over of the edges of the parts for the Black Widow paddle...

I read the instructions for polishing the brass in the Black Widow paddle using fine sandpaper...The problem is that the sandpaper quickly loads up and stops cutting...I would go to an automotive paint supply and buy "wet-or-dry" emery paper...Wet or dry is usually a gray color on the back side with black abrasive on the business side...

Tape the paper to the table as suggested, then apply a small amount of water to it and start sanding...The water will hold the metal particles in suspension and allow the paper to continue cutting, and the cutting will be FAST...As the cutting continues, the water will thicken into a brass colored slurry which can be rinsed or wiped off, after which sanding can continue using the same sheet of sandpaper...This method is excellent for polishing the edges of plexiglass...
