Homebrew PCBs

I just signed on to this group.  I was in the commercial PCB 
industry for many years - tech service for DuPont Riston.  Photo 
imaging is just too much of a hassle for me to do at home and toner 
transfer seemed like a good alternative if it would work.  I've been 
looking for TT information to build PCBs for some time and it looks 
like I found it.  

I also want to etch brass and bronze sheet for some modeling 
projects.  Has anyone tried toner transfer to etch say 0.005" think 
metal?
