Heh - I only just noticed that :)
My etchtank is a modified polypropylene cereal storage tub. I drilled three
holes in the cover (one for the heater's power cable, one for the bubbler
hose, one for a thermometer). The only problem is, when the bubbler is
running, it produces a fair bit of FeCl3 mist. Plugging the holes with
Blu-Tack and kitchen paper (and careful setting of the air pressure) seems
to lessen the effect though.
The only major problem is the loss of etchant when the tank gets drained and
cleaned. I seem to be losing about 10mL each time I use the tank. Not a big
problem, 'cos I can always top the etchant up, but it gets annoying when you
need to etch a Eurocard and the etchant level is a bit too low to etch the
board properly :-/

Later.
