The _only_ reason I used CAD software to design these things was to farm
out fabrication to a CNC shop. Of course I don't _need_ to use CAD software
to design covers and doublers, and don't _have_ to farm out the fab to a
machine, but it will save me a lot of time making 18+ of the large
perimeter/doughnut shapes in .040 by hand -- not to mention all the pilot
holes -- and will make the parts more uniform than I ever would. The cost
for 7 pairs of covers & doublers -- $113 USD, including material -- is,
IMHO, quite reasonable. The decision to flush mount does, obviously, entail
more work. That decision having been made, I prefer to minimize as much of
that work as possible, 'cause I'm still lazy. That I could design and fab
these myself is, to me, irrelevant. For those who would rather knock these
out by hand... fine, have at it.
As for the ongoing flush vs. surface mount debate, I'm not eager to
participate. The points made so far are all things I considered at length
before making a decision. No doubt, they will be useful to those still in
decision-making mode, but I've no interest in defending what is just a
personal preference after weighing the issues -- on my own scale. That is,
after all, one reason we build these things -- to do it the way we want,
and produce the result we prefer. (Call me contrary, but the more
emphatically someone asserts his way is the only correct way to do
something, the more careful consideration I tend to give the alternatives.)
Bottom line is I decided to flush mount the covers, and have a procedural
plan that I think will maximize the odds of success. To each his own.

I don't think that I'd need to design a patch with CAD though. A
sharpie, coffee can and a straight edge is all you really need.
