Rather than use string that can deteriorate try nylon ties.

More importantly replace the original screws so they don't have a chance to 
destroy what you're trying to save.  As has been pointed out repeatedly the 
right tools are cheap and available through a variety of sources.  Anyone 
working on anything that has value should value it enough to do it right.
