Hey the page of R.G. is interesting, didn't know that one.
<http://www.prototrains.com/>

He uses a pump to spray the etchant. too bad i didn't buy that all  
glass/teflon chemical pump on ebay..


I have terminated the rotary etcher a while back due to various problems,  
and it will be a while before i attempt a spray etcher again, but i'll  
still be very interested to hear about your system.

Also, the photo-process stuff is sure interesting for many here, as it is  
basically the same problems with PCBs you have/had to solve.

It will be great to read more about your setup, and i think there are  
people here that know how to solve the bubble-problem with laminate.
