Homebrew PCBs

Does sound rather messy but maybe fast. I know you can get a fine mix of
flux and solder that is used for surface mount. I wonder if you could spread
some of this paste on the board and then cooked it in the pan. Is there an
easy way to form tiny particles of solder? I know the first lead shot was
formed by pouring it from a great height and letting it land in a big pail
of water.

I did it this way:  I used a frying pan, peanut oil and something to keep
the board off the bottom of the pan.

Solder dip and wet rag. 

The oil residue was tough to remove.  I would not use this method on
critical circuits though.
