Things are tight in this circuit and one result of this is that
pad OD's are not much bigger than the corresponding ID's.  (Space
is at a premium in the enclosure.)  So drilling the pads open a
bit for eyelets or other wires is not going to be easy, or even
possible.

[ PCB was originally designed expecting to go to a proto-house
but I really want to get it done before leaving town tomorrow. ]

I've just tried a couple things, and the best answer is that of
leaving the components a bit higher off the board and getting in
there with a small pencil iron.  I do have some space behind the
board, so in some cases (depending on which side the signals
connect to) I'm going to mount the components on the back of the
board.  I have space on the back since I had already planned to
mount the TO-220 components on the back for easier heatsinking.

Since this board will be in a car, I'll probably have to pour on
some epoxy, hot-glue or similar to secure the components better.


Thanks,
