Lots of potential banana skins with this idea.
I hope you have good insurance!
When you start cutting it up make sure you know what it is made of. On some a/c parts of the undercarriage are made of Berilium. Highly toxic if the dust is inhaled. Also Some use depleted uranium as mass balance weights for flying control surfaces. Not sure whether the Tristar uses either of those materials but you would do well to get in touch with some old Lockheed engineers as 'technical advisors'.
That is if you can find one who is so down on his luck he would associate himself with such a project.
Oh hang on haven't I just done that....bu88er!
