Hi,
I will make the tank from glass 'cause Steve says lexan is no good (thanks
by the way, would have been bad if it cracked after some time.).
Found some 5mm glass, will use it for bottom and sides, the top will maybe
be phenolic board (not PCB, 5mm thick variety).
The 5mm glas will be sturdy enough, and i don't think it will break even
if some part goes flying inside. Also, it will be heavy and help dampening
any vibrations.
I reckon a transparent top is not all that useful, after all the spray
would cause droplets to form which would obscure the view pretty soon. I
will use the sides to view which get cleaned by the spraying etchant.
Right now i wonder what material i'm gonna use for the bearings (of the
ones i have, i'm not buying teflon right now) and how to affix it to the
glass floor....
Must identify the materials i have, i think there are chip burn tests and
similar methods which are reasonably easy to do.
thanks
ST
