imperial droid?? any info??

[deathproof]

I'd love to build one of these as well... I had started gathering some photos from across the web.

I'm wondering how they actually built the life-size version for Empire... if they hand carved all the parts, used a vacuum table, if they used existing pieces, etc. We all know parts of a jet engine were used for IG-88's head and for other thing in the original films.

I wish I could find some sort of production notes and blueprints on exactly how they built the probe droid.
