Harbor Freight Chop Saw Fix

I just about ruined the armature on the chop saw cutting 
bricks. The dust got into the brushes and almost ate up 
the brushes and segments on the armature. Chopsaw.jpg 
shows the bad spot and Chopsaw2.jpg shows what it looks 
like after about .005" is removed from the copper. Small 
cuts and slow feeds should be used or you'll rip up the 
segments from the armature. Then use a file at a slow 
speed if the finish isn't good. After the file use about 
a 500 grit sand paper to smooth out and scratches. After 
all that is done clean very carfuly between each segment 
to get the chips and copper dust out or it will short 
across several segments burning things up again. Questions, 
leave a message on rec.crafts.metalworking.
