First attempt at self-reproducing machine tool (SRMT)


In 1984 I coined the term Replikon to denote a self-reproducing *conventional* machine tool closed to matter reproduction of non-stock parts, open to energy input, and open to control inputs from the operator; this definition was not published.
From about 1993-2003 I discussed the concept in news:rec.crafts.emtalworking. Look for "SRMT" and my name there.

constructed a self-reproducing machine tool in 1995-1997 and sold it for $300 in 1997. 

The machine incorporated its own reproduction template, a drill jig made from 3/8 cold rolled steel. 

The method of incorporation was to include the 4x6 x 3/8 inch drill jig with its 3 x 5 inch array of 1 x 1 inch spaced 1/16 inch holes, 15 holes in all, with the exception of a 5/8 bushed hole in the center, as the cross slide in the cross vise, replacing the vise, supporting the included four jaw lathe chuck in its vertical axis mode, unfortunately not shown. 

The horizontal axis mode is illustrated in the picture here using the collet indexer component. 

120 teeth were cut into the chuck rim with manual feed and a rack gear cutter.

The jig could be copy drilled or lacking a copy, originated with the cross vise.

The jig patterned matching holes in the base and vise.

The jig was a working part of the machine.

The jig was sold with the sold machine, and no jig copy was kept.

Since the advertisement and not the cash receipt state "self-reproducing milling machine", and
since the cash receipt names a private buyer, it is not provided here; copies are available by correspondence.

The machine--the pair of machines--took two years to build.
