[CAUT] Fall board

[Douglas Wood]

These are all good ideas. I have another that is very easy to try  
first. Us bicyclists are familiar with a product known as "white  
lightning". It is a waxy chain lube. It is designed to soak into the  
chain and coat the pins and then dry, leaving the wax behind. One  
treatment is almost always successful. Wipe with a cloth or tissue or  
paper towel after. Try not to let it drip too much, though the  
solvents don't seem to touch the finish. A second try is worth the  
very little time and expense. If there's still noise, look for other  
things--there are supposed to be rubber buttons on the backside of  
the lip, e.g.
If there is still noise, and you're sure it's the hinges, then  
disassemble them, etc.
