Yes, but, cost to build? Space required? Possible failure
considerations? (doesn't he mention having ferric chloride spraying
around the garage in one particular disaster?)
It does look great, and I'd be working more on etching brass sheet
(non-PCB) like he is, but a lot of us here are probably thinking more
along the lines of "what's already laying around and twenty bucks for
what's not"
Regarding the floating & flow discussion, you guys reminded me of
something (photography) related I read a while back - a guy suggested
putting a vibrator in the tank. He was using it in the corner of a paper
developer tray as his primary agitation and claimed that it, a small
"egg" type vibrator, provided good agitation and even development. (?)
Personally, I just rock the paper tray.
Makes me think though, if I use the "floating" (horizontal)
configuration in the etch tank with a vibrator moving the etchant, and
helping to agitate and move the heavier etch products away from the
material, that might solve one of my current cheapo-engineering problems.
Then the question is whether it would do the same in a vertical
configuration, as I need to accomplish two-sided etching. hmmm. =8/
