Homebrew PCBs

Tom-

Up here in Canada lye is commonly (and cheaply) sold in Home Hardware
stores. Soap-making hobbyists buy it to make soap. Some food stores
here sell "Gillette's Lye" in the cleaning supply dep't; it is used to
clean clogged drains. Incidentally the claimed purity of the
Gillette's is higher than some lab grade NaOH I purchased at much
greater expense! (not that the difference has any practical
implication, as far as I know, for my purposes).
