old aperture lens - fix .2

well this time, the mech. was easiest, 

i used some spring from old CDrom but it was a little too long

looked like this .. 

then i thought why not to use a rubber band? i made alot of those things from bicycle tire last winter..

cut a nice piece and made it look like this

if i would have smaller spring or rubber i would use it but i dont..

but well check it out, all is working again ;) 

nice... 

i am sure there is multiply possible ways to made it work : )
