Homebrew PCBs

Well, if stainless is no good in HCl,
which Materials would be good for constructing
a PCB holder for a vertical etch tank?


I think carbon reinforced tubes are very strong. (from rc model supply)
Does the HCl attack the carbon fibers? I think it should not be
a problem with epoxy resin (as pcbs are also this material).


How to construct a holder?
It should allow for etching on both sides and the full surface (no clamps 
or such stuff)


Any hints appreciated.

thanks

Stefan
