Anybody experience in extracting precious metal parts of an f-8 crusader jet/ jet engine .My friends have dumped me 19 engines, plus another 8 still intact. They were able to buy it as scrap from the philippine airforce.I have started to segregate 1 engine, and noticed some silver in the wiring, platinum in the contacts, maybe also in the nozzle tips, a lot of aluminum, nickle alloys titanium alloys , tin, copper silver wires any info i can get would be of much help.
