I found a good source for it at All Electronics
(http://www.allelectronics.com)
They supply the solid stuff (ferric chloride) rather than the more
'spillable' solution. I found ferric chloride works better than
anything else I've tried. I have found them to be prompt and helpful.
They are also a treasure trove of 'odds and ends' for all kinds of
projects.

If you are making PCB's, they also stock 'transfer film'. Just print
on a laser printer and iron on to the PCB. It transfers better than
laser-anything else. I was getting really frustrated (trying all kinds
of papers and other materials) until I found this stuff ... never had a
bad board since!!!! I even do double-sided with it with great results.

There are a few schematic capture and PCB layout programs for free that
seve me well ... making it much easier than 20 years ago. Hmmmmm ...
can I produce an EFIS for under $1,000?

Hope this helps.

Getting ferric chloride from Radio Shack is getting problematic. Is
there a common household chemical that I can use for etching a circuit

to do it in the not to distant past, but I can't find anything about it
in my back copies of Kitplanes.
How 'bout:
