Holy crap! I am WAY too lazy for all of that. I was just thinking for self-use, something a step above trying to use a knife to cut around the edges of a paper template.

I see from the link in the comment below yours that I could make some amature ones from aluminum and scissors - I might give that a try before I go professional. ;)

But what I *really* want to know is - you've done this before? What did you make? Why? How? Where? I want the scoop on how such arcane and detailed knowledge was acquired!
