Mounting into an enclosure.
Unlike previous incarnations of this rig, the jacks are not board mounted. This was done primarily to make room for board
mounting the two band filter parts, but has the side benefit of making a wider choice of enclosures besides an Altoids tin
possible.
The drill template below can be used to locate the holes which need to be drilled into an Altoids tin or other enclosure. The
diagram should print to true scale, but make sure the printer setting is for 8.5 x 11” paper and no page scaling.
Double sided tape can be used to hold the template down, but be sure to get it lined up well first. Folding the template
over the sides of the tin will locate the holes for the jacks.
Drilling the thin sheet metal of the tin does not generally result in the cleanest holes. The best results are obtained if you
have a drill press. You should always make a dimple to center to drill bit with a center punch or other shape, pointy object.
Then drill a pilot hole using a small diameter bit, say 1/16”. This will keep the larger bits from wandering when you make
the larger holes. Back up the tin with a small block of wood so you don't deform the tin as you press in with the drill. Use a
hobby knife or round file to de-burr the hole.
The phone and power jack can't be located quite far enough down from the lip of the tin so that the lid will close. A small
notch in the lip of the lid will have to be made with a round file to make clearance for the mounting nuts for the jacks.
