Homebrew PCBs

Fred,
     It might be cheaper and simpler to use a dental drill, the new 
kind that shoots grit instead of using a drill. The problem with 
Mechanical Etching is the epoxy in the board. It is very abrasive to 
the bit. There is probably a type of board out there that will give 
better bit life. It would be nice to see someone come up with a
real easy way of making circuit boards. Tilting the table does not
remove the abrasive aspects of the epoxy in the board. At one
point I was going to submerge the board in an oil pan while it
gets milled. Then the thought of having oil soaked grit to get rid
of hit me!
