Basically, it can't be done in your basement.  Not if you want reliable
results that you can *use*, as opposed to a demo that more or less works
sometimes.

Convincing copper to stick to the insides of the holes is tricky.  Making
it stick reliably and consistently requires fussy control of things like
temperature and solution chemistry.  It's just not a basement process.
