I'm looking to do some Bike Volunteering/Bike Cook

I'm an intermediate bike mechanic and fixie rider.

I know how to clean,wax,degrease and rust proof all
metal parts.

I know how to repair flats,install tires, align chains,install cranks
install bottom brackets,install chainrings,install cogs and lockrings.
I know how to install some cross levers and brakes. I know how
to install stems ,bars and wrap bar tape

Weaknesses: headsets,forks,truing,geared bikes

I'm not looking to get paid, and I don't want to be paid. I just want to volunteer 1 day of the week to grow and learn more about cycles ,and to offer
my services to those that need them.....

Are there any places that are looking for bike volunteers
or bike cooks?...I want to shop-volunteer.. I want to keep my hands
dirty at all times...
