Homebrew PCBs

Hi Alan,
        I put a wall of masking tape around the edge of the
PVC bed. This keeps the dust from vibrating off the bed into
the leadscrews. Since I went back to 16,000 RPMs the dust
is not so bad. The best fix is to put 5 drops of motor oil
on the board. Spread it around with your fingers. This will
cut down most of the dust. Then wash the board with dawn
dish detergent.  If you think that dust is bad,try sanding,
cutting and shaping MDF wood. Then some PVC! I have it 
everywhere!
