[Elecraft] Help w/KPA100 paint removal

[Don Brown]

Hi

The heatsink is really not painted it is anodized so it is much harder to mask off areas on the metal. I use a Dremal tool with a small wire brush to remove the anodized coating. You need to run the motor at a slow speed or the brush may get away from you and damage an area you don't want cleaned. Another way to is to glue the sandpaper to a small square wooded stick and use it to remove the coating. Put masking tape over the areas you want to protect and carefully sand the screw mounting areas.

  Hello All:

  I'm building a KPA100 and I'm at the point I've got to remove the black
  finish paint around the 4 screw holes on the top and sides of heat sink.
  The manual says to do this with the provided sandpaper.  I'm concerned about
  scratching the surrounding surface.

  I'd really like this to look nice when I'm done.  I'm wondering if anyone
  has tried alternative methods?  How about a Dremmel tool?  I don't see how
  I'm going to remove all the paint around the flat surface of the hole
  without making a scratch or two that wasn't intended?  I wish these areas
  were never painted in the first place.

  Frank, W4FMS
