For many conversions or scratch build projects we need small discs: buttons or rivets for instance.
Some punches are available commercially but they tend to be for punching smaller discs up to 2 or 3 mm in diameter and limited to very thin plastic card.
The attached pdf contains instructions explaining how I made a jig which can punch out nice, clean discs from 1.5mm up to 8mm diameter out of plastic card or soft metal up to 1mm thick.
