Homebrew PCBs

Hi

I've taken some pictures of my new PCB drilling machine, and 
made them available online at
http://home.alphalink.com.au/~seychell/drill_MkII.html

Hope the pictures don't take too long to load.

The machine has virtually come straight from the workshop 
and I've yet to use it for PCB production. When I start 
using it I'll find all the problems and most probably will 
be making alterations. One feature I'm thinking of adding is 
laser diode pointer for guiding the hole location on the 
PCB. I've never fiddled around with visible laser diodes.
Does anyone know if those cheapy red laser diode modules be 
any good for this ?
