Drilling holes is boring.
That's supposed to be a joke. Get it? Drilling is boring. The words "drill" and "bore" are synonyms. Uh... yeah.
Seriously folks, drilling holes can be tedious, especially for projects demanding a large number of holes; i.e a whole bunch of holes.
I think the worst part of this hole drilling business, besides the bad puns, is doing all the measurements that determine where the holes should go, plus marking these measurements on the work piece, etc.
But what if there were a way to do most of the measuring in one step? E.g. put the measurements on a piece of paper, and then transfer those measurements directly to the piece.
Well, that's essentially what this instructable is all about.
By the way, the example work-pieces in which I'm drilling holes are some pieces of aluminum channel that I think used to be part of a Venetian window shade, in their former life. These pieces are intended to serve as heat sinks for some hot little LEDs. Maybe you'll see them again in another instructable of mine.
However, the particular shape of these pieces of metal and the pattern of the holes is not important to this instructable.
This instructable is intended to illustrate the general principle of transferring marks on a piece of paper, onto marks on a piece of metal, upon which holes can be drilled.
