Homebrew PCBs

Just wondering if anyone has run across something on building a small
dip soldering setup.

Someone (I thought it was on this list) mentioned they had seen a small
setup that was more or less a set of rails running through a solder pot.
The board to be was put on the rails or angle and simply pushed through
the solder by hand.

Anyway just wondering if anyone has run across info on how to do this or
what to watch out for when doing this.

Tnx

Dave
