[TheForge] die for a small hinge barrel

[Dave Mudge]

Somewhere in the past I saw a die used with an arbor press.
 This was for making the barrel part of a small hinge.
 As I remember it, the die was a piece of solid stock that had a
vertical slit for the flat hinge material to slide into.
 At the bottom (and off-set) of the vertical slit was a drilled hole
whose diameter would be the diameter of the hinge barrel.
 The flat stock was slid into the vertical slot and when pressed with
the arbor press,
 the flat metal would go down the slit and curl in the round hole at
the bottom thus forming the hinge barrel.

 Question: Is anyone familiar with this hinge die set-up? Was it in a
book or perhaps a video?
 Can anyone tell me where to find a sketch or other info about this process?
 Any help would be appreciated.
 thanks,
