Was looking for a hole punch solution for a craft project,
and
got to thinking: how would you punch a hole in the middle
of
an arbitrary piece of paper/cardboard.
There are some solutions:
Drill
Laser cutter/craft cutter
extra huge hole puncher
Custom die cut
Metal punch
Each of
these has problems, whether cost, size limits, or
clean cuts.
Which got me to thinking: is there a way to make a punch
where the cutter and receiver would line up perfectly in an
arbitrary position on the stock in question?
I did a search, and found nothing.
Then I thought of this: what if the cutter and receiver had
specially positioned and oriented magnets that allow you
to
line up the punch, then fix the receiver below? Set the
whole
thing on a flat surface, then punch!
Or, you could align the magnets at the edge of the
material,
and glide the rig to where the hole needed to be.

If you are willing to drill an initial (small) hole, then this tool can punch out a nice smooth large hole. [Vernon, Jul 23 2016]

The magnet solution is slickety slick. I think it would work. Nice halfbake SK. |

Yay, magnets! See [link] for related idea. |

The anvil might need chamfered edges to assist
with minor misalignment depending on stack
thickness. |

Handgun loaded with .22 short wadcutter rounds. Job done. |

I wondered if hold was intentional, referring to the ability of this punch to get a purchase on any area. |

Size of tool(∝ energy) versus work space orientation. A laser via conduction cable would have smallest head and the most flexibility in a tight corner. Magnets won't slip around a fold. |

Best to punch the clean sheet and, because of planning, fold and assemble around the hole. |

Hummingbirds already can put their beaks in any flower at any angle. |

They just need a portable back pack punch strapped on and a bit of training. |

Or maybe smallish flamethrowers. |

Those programmed permanent magnets might be useful
for fine alignment. |
