Perforaptor is a semi-manual robot which was designed to make accurate perforated angle for the Contraptor set. When design changed from 3/16" to 1/4" holes, perforated angle no longer had to be accurate, and this contraption was abandoned. Maybe it will be revisited in the context of producing perforated angle for the set.

Perforaptor is basically a light duty, stepper-driven drill press built with asingle purpose to bore holes in the center of aluminum angle stock,movable along one axis. It uses a cheap $20 corded drill (Power Glide VSR from Ace Hardware), and about $130 worth of Contraptor materials, not counting electronics.

The design of Perforaptor uses old linear motion components (leadscrew in the corner of sliding element). The design was never completely documented. See attached Sketchup file and project history.
