Hi Ryan,

I got copper foil from the big hobby store.  It is used for "tooling" metal
pictures.

Then I got a compass from the office store.  One of the good ones with a
screw wheel adjustment that will not slip while making a circle.

The office supply store has just the compass part for about $5.  I bet you
could make one free with a little wooden board, a nail, and an Exacto blade
;-))

I just used a sharp metal tip clamped into the end instead of the usual
pencil lead.  Just turn it in a circle for awhile and soon it will slice
through.  Don't use much pressure at all.  Be sure to cut the larger circle
first ;-))  Also, be sure the compass is big enough to cut the circle you want.

Cheers,

	Terry
