Homebrew PCBs

Hi Tom,

I used to work at a "job shop" too at one time, for a few years. Many 
years ago and for someone other than myself, but I learned quite a 
bit. The owner was quite nice and let me learn all about the 
bussiness. I would have stayed or got into my own, but for the 
terrible smells. After a while it got to the point that I got almost 
sick just thinking of the smell... :(

I was actually doing electronic design, so I just moved to a cleaner 
place to work. And that was that for the PCB manufacturing experience.

Tom, I do have one question.
What kind of table surface would you suggest for the laser cutter?
I just have a throw away cardboard surface. With the compressed air I 
would think there needs to be an exit somewhere, so a metal mesh or a 
perforated surface or something with negative air pressure? Is there 
something that works the best?
