Have set up the
garage more. Went to home depot and IKEA. I bought a small table on rollers and
also bought a bench grinder and sanding station. I have been reading up on
methods of sanding. To my surprise folks seem to be using a course grit
sandpaper (60-80) but the FAA Acceptable methods indicates 150 or finer. More
reading suggests that Aluminum Oxide sandpaper is acceptable. However silicon
carbide abrasives are not good to use as the silicon can contaminate the
aluminum. Black sandpaper contains carbon, which can accelerate corrosion. Steel wool on
aluminum is not acceptable either.
