Homebrew PCBs

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
