You're right, and my heart bleeds for you. However, even subtracting the 
shipping, it was an expensive way of buying 15 sheets of paper - and at 
least if they'd been blank sheets I could have re-used them...

No, but in the intervening year I have added more *free* articles to my own 
website, on other topics. Work on other stuff has gotten in the way of 
paying serious attention to PCB milling, but it is still on the list.

And by the way, for the benefit of other visitors to John's website, before 
you pay $35 for his plans of a 4th axis constructed out of "Two gears, a 
floppy drive stepping motor and some PVC" (to quote John' own words), check 
out:

http://www.jeffree.co.uk/Pages/divheadmk2.html

which describes how to construct a CNC 4th axis that, unlike John's design, 
is actually usable for light milling of materials harder than soft wax or 
wood - I have successfully used it to machine items in brass and steel, for 
example.

You're right...and a year on, $18 for sweet FA is still way too much.
