Step 3Drilling Jig
For speed, you need to be able to drill a hole in the same place in the CD consistently, for this I designed and built this jig. It has to be the ugliest conglomeration of wood and nails I've ever thrown together.
I found that the hole should be drilled anywhere on the ring where the central clear area meets the foil. This will allow you to nail through the CD without the CD below it needing a hole in it. The pictures should explain better than I can.
A stack of disks can be push into the jig once the drill bit is centered on the cross, at which point 10 or more disks can be drilled at a time, tipped out and then another load done. Easy!
If you don't have a pillar drill, build the same jig then screw a baton across the top with a hole in it in the right place through which to stick your bit. This should be equally quick. I ended up using my Dremel with a plunge attachment and a 3mm metal bit.
