I recently stumpled upon the contraptor site and love the idea of it. Since I live in Europe I would be looking into the metric contraptor and hope that it is still alive and kicking and making progress.
Whilst I was thinking how I could acquire all the parts, I wondered if it is not possible to create a super mini cnc, which solves the only task of drilling the holes into say a 1m beam of the aluminium profiles. The meter could then be cut manually. That way one could basically bootstrap building parts of the complete kit, e.g. for building the CNC contraptor and one would require to purchase only a minimum set of new elements.
When the material to be drilled is only the beams of profiles, it would save an axis and make the bootstrap CNC machine easier and simpler to build, wouldn't it? I'd love to hear from you,
