Warlock Pinhole Drawing

A Pinhole drawing was a very important part of the Pinball Design Process.  Before the age of computer aided design (CAD) the dimensions and layout of the final playfield design had to be transfered to wood.

The process was very simple.   The design was drawn or copied to a sheet of mylar.   A technician would attach this mylar sheet to a blank sheet of playfield stock.  The technician then would take a metal punch and transfer the locations of the inserts, playfield posts and any other design detail that would later be drilled into this blank.

After the mylar was removed there would be small holes the size of the punch used in the mylar.  Hence the name “Pinhole Drawing”   Generally there is only one such drawing per game so this is the father of all the playfields of this title.   Pinhole drawings are rare and very collectable.   This is also a very small production title.
