Some time ago it occurred to me that since I've owned various printers that will produce CD labels or can print directly on to printable CDs, using a CD as a degree disc (mainly for setting points timing) would be useful. With that in mind, I knocked up a drawing to do exactly that.

The precise method that you use to print the disc will of course depend on what printer and software you have, so I'll leave that as an exercise for you. It's a good idea to do a few practice runs, as I've found that different printers seem to need a tiny nudge in the settings to get the output dead-centre on the disc or label.

Whilst it was originally intended for CD size, I've kept the image reasonably high-resolution; consequently it will enlarge well if you want to use other size media.
